Sourdough Starter Preparation: The Foundation of Flavour
A great sourdough pizza starts before you even mix the dough. Your starter is responsible for the fermentation, flavor, and structure of the crust.
A weak or inactive starter can leave you with a dense pizza base that struggles to rise. A strong starter creates a dough that is more extensible, easier to shape, and capable of developing that beautiful open crumb sourdough lovers look for.
Before starting this recipe, make sure your starter is active and ready to work.
How to Know Your Starter Is Ready
Feeding Schedule for Peak Starter Activity
A sourdough starter is at its best when it is strong, active, and predictable. For pizza dough, you want a starter that has enough energy to ferment the dough properly without adding too much acidity.
Building the starter gradually before baking day, rather than using it directly from the refrigerator, gives the natural yeast time to become fully active and may support a more predictable rise.
Here is the feeding schedule I use for this Pizza Portofino dough.
Two Days Before Baking: Morning Feeding
Start by reducing your starter.
Keep 20g of mature starter and discard the rest. Then feed it with:
- 40g bread flour
- 40g water
Mix well and leave it at room temperature, ideally around 70–75°F (21–24°C).
At this stage, you are refreshing the starter and increasing its strength. Within several hours, you should begin seeing bubbles forming, and the starter should gradually rise.
One Day Before Baking: Evening Feeding
Repeat the same feeding process:
- 20g starter
- 40g bread flour
- 40g water
After this feeding, your starter should reach peak activity in approximately 8 hours, making it ready to mix into your pizza dough the following morning.
The ideal time to use your starter is when it has reached its highest point — when it is full of bubbles, slightly domed on top, and has not yet started collapsing.
If Your Kitchen Is Cold
Temperature has a major effect on sourdough activity.
If your kitchen runs cooler than normal, fermentation will slow down. To help your starter stay active, you can:
- Place the jar inside a turned-off oven with the light switched on.
- Use a proofing box set around 75°F (24°C).
- Keep it away from cold windows or drafts.
A small temperature adjustment can make a big difference in fermentation timing.
Expert Tip:
A healthy starter is not just an ingredient. It is an active community of wild yeast and bacteria working together.
The goal is not simply to make it rise. The goal is to build a balanced starter that produces flavour, strength, and consistent fermentation.
Troubleshooting Common Starter Problems
Even experienced sourdough bakers run into starter problems. The good news is that most issues can be corrected with small adjustments.
Starter Is Not Rising
If your starter stays flat after feeding, check these common causes:
Water temperature:
Cold water can slow fermentation. Try using slightly warm water around 80°F (27°C).
Flour strength:
A higher-protein flour can give your starter more nutrients and structure. Try switching to a stronger bread flour if your current flour is not performing well.
Water quality:
Chlorinated tap water can sometimes slow down fermentation. If you are unsure about your water supply, leave tap water uncovered overnight before using it. This allows some chlorine to dissipate.
Starter Tastes or Smells Too Acidic
A very sour starter is usually a sign that it has consumed most of its available food and needs a stronger refresh.
To reduce excess acidity:
- Discard more starter before feeding.
- Increase the feeding ratio to 1:3:3.
- Repeat this process for one or two feeding cycles.
This gives the yeast more fresh flour and reduces the concentration of accumulated acids.
Liquid Layer (Hooch) Appears on Top
That dark or clear liquid sitting on your starter is called hooch.
It is a sign that your starter is hungry and has run out of food.
To fix it:
- Pour off the liquid.
- Keep only a small amount of starter.
- Feed it immediately with fresh flour and water.
A little hooch is normal and does not mean your starter is ruined. It simply needs attention.

Ingredients List With Precise Measurements
Accurate measurements matter when making sourdough pizza. Unlike regular dough recipes, small changes in hydration can affect how the dough stretches, ferments, and bakes.
Measuring by weight gives you much more consistent results than using cups.
For the Sourdough Pizza Dough
Makes Two 12-inch (30cm) Pizzas
Active Sourdough Starter (100% Hydration)
100g
Use a ripe starter that has passed the float test and is showing strong activity.
Bread Flour
500g
Choose a high-protein flour with around 12–13% protein.
Good options include:
- Caputo 00 flour
- Strong bread flour
The right flour helps create a dough that is strong enough to hold toppings while still developing a soft, open crumb.
Water (Room Temperature)
325g
This creates approximately 65% hydration.
This hydration level gives a good balance:
- Easy enough to handle at home
- Flexible enough for stretching
- High enough to create a lighter crumb
Fine Sea Salt
10g
Salt strengthens the gluten structure and controls fermentation while adding flavour.
Extra Virgin Olive Oil
10g (optional)
Adding olive oil creates a slightly softer texture and a richer mouthfeel.
Expert Tip: Weigh Everything
When working with sourdough, precision matters.
Even a small difference in water can change your dough hydration and affect:
- How sticky the dough feels
- How easily it stretches
- How open the crumb becomes
A digital scale accurate to 1g is one of the most useful tools for consistent sourdough baking.
For the Portofino Pizza Toppings
These toppings are inspired by the fresh flavours of the Italian Riviera—bright pesto, creamy cheese, savoury chicken, and earthy vegetables.
Pesto
120g (about ½ cup)
Use homemade pesto or a high-quality store-bought version.
For the most authentic Portofino-inspired flavour, look for Ligurian-style pesto made with:
- Genovese basil
- Pine nuts
- Parmigiano Reggiano
- Pecorino cheese
- Garlic
- Extra virgin olive oil
The quality of your pesto will have a noticeable impact because it becomes one of the main flavours of the pizza.
Cooked Chicken Breast
200g
Slice or shred the chicken.
Grilled chicken adds a slightly smoky flavour, while poached chicken keeps the topping softer and more delicate.
Caramelised Onions
1 large onion (around 200g)
Thinly slice the onion and cook slowly in olive oil until deeply golden.
This step takes patience, but it creates natural sweetness that balances the salty cheese and savory chicken.
Cremini Mushrooms
150g
Slice and sauté until golden before adding them to the pizza.
Cooking mushrooms first removes excess moisture and prevents a soggy crust.
Fresh Mozzarella
200g
Use either:
- Low-moisture mozzarella
- Fior di latte
Tear it into small pieces and distribute evenly.
Parmigiano Reggiano
30g
Finely grate over the pizza for extra depth and a nutty, savoury finish.
Pine Nuts
2 tablespoons
Lightly toast before adding.
They add a delicate crunch and reinforce the pesto flavour.
Fresh Basil Leaves
Add a handful after baking for freshness and aroma.
Semolina or Cornmeal
Use for dusting your pizza peel.
It helps the dough release easily before transferring it to the oven.
Ingredient Substitutions and Dietary Adaptations
Step-by-Step Dough Making Instructions
Making sourdough pizza dough is a slow process, but each stage has a purpose. You are not just mixing flour and water. You are building strength, developing flavour, and creating the structure that will give your Pizza Portofino crust its crisp outside and soft, open crumb inside.
The biggest mistake many home bakers make is rushing the dough. Sourdough rewards patience. Pay attention to how the dough looks and feels at each stage rather than relying only on the clock.
Mixing and Autolyse: Develop Gluten Without Effort
The first step is building the foundation of your dough.
Autolyse allows the flour to fully absorb the water before fermentation begins. This simple resting period helps develop gluten naturally, making the dough smoother, stronger, and easier to handle later.
Step 1: Combine Flour and Water
In a large mixing bowl, add:
- 500g bread flour
- 325g room-temperature water
Mix with your hand or a spatula until all dry flour disappears.
The dough does not need to look perfectly smooth at this stage. It will feel rough and slightly shaggy, which is completely normal.
Cover the bowl and let it rest for 45–60 minutes.
During this time:
- The flour absorbs the water.
- Gluten development begins naturally.
- The dough becomes more extensible and easier to stretch.
This means you will need less effort later when building strength.
Step 2: Add Starter and Salt
After the autolyse period, add:
- 100g active sourdough starter
- 10g fine sea salt
Use a pinching and folding motion with your fingers to mix everything together.
Continue until the starter and salt are evenly distributed throughout the dough.
At this point, the dough may feel sticky and uneven. Do not add extra flour. The dough will become smoother as fermentation and stretch and folds develop its structure.
Visual cue: The dough should feel combined and cohesive, even if it does not look polished yet.
Stretch and Folds: Building Dough Strength
Instead of traditional kneading, sourdough pizza dough develops strength through gentle stretch and folds.
This technique strengthens gluten without aggressively working the dough.
During the first 2 hours of bulk fermentation, complete:
3–4 sets of stretch and folds every 30 minutes.
How to Perform a Stretch and Fold
- Wet your hand slightly to prevent sticking.
- Reach underneath one side of the dough.
- Gently pull the dough upward until you feel resistance.
- Fold that section over the top.
- Rotate the bowl about 90 degrees.
- Repeat until all four sides have been folded.
After each set, the dough should feel tighter and stronger.
At the beginning, the dough may spread quickly after folding. With each round, it should hold its shape better.
Expert Tip: How to Check Dough Strength
After the final stretch and fold, your dough should feel:
- Smoother
- More elastic
- Stronger
- Less sticky
If the dough still feels loose and weak after four sets, add one more round.
Higher hydration doughs often need extra support.
A useful test is the windowpane test:
Take a small piece of dough and gently stretch it between your fingers.
If it stretches thin enough to become slightly translucent without tearing, the gluten structure is developing well.
Bulk Fermentation: Building Flavour and Rise
Bulk fermentation is where your dough starts becoming pizza dough.
During this stage, the natural yeast and bacteria in your starter produce gases and organic acids that create:
- Better flavour
- More complex sourdough character
- A lighter crust texture
Cover the bowl and allow the dough to ferment at room temperature:
70–75°F (21–24°C)
The dough is ready when it has:
- Increased in volume by around 50–75%
- Visible bubbles on the surface
- A slightly domed appearance
- A soft, puffy texture
This usually takes around 4–6 hours, depending on:
- Starter strength
- Room temperature
- Flour type
Visual Signs Matter More Than Time
The clock is only a guide.
A properly fermented dough should:
- Jiggle slightly when you shake the bowl.
- Look airy and alive.
- Hold some structure instead of spreading flat.
If you wait too long, the dough can become overproofed and lose the strength needed for a tall, airy crust.
Dividing and Pre-Shaping the Dough
Once bulk fermentation is complete, it is time to prepare your pizza portions.
Step 1: Divide the Dough
- Lightly flour your work surface.
- Turn the dough out gently and use a bench scraper to divide it into two equal pieces.
- Each dough ball should weigh approximately: 460g
Try not to press out too much air while dividing. Those fermentation bubbles are what help create a beautiful crust.
Step 2: Shape Into Dough Balls
For each portion:
- Fold the edges toward the centre.
- Continue folding until the dough forms a tight shape.
- Turn it seam-side down.
- Roll gently on an unfloured section of your work surface to create surface tension.
You want a smooth, tight dough ball that can hold its shape.
Step 3: Rest Before Cold Fermentation
Place each dough ball into:
- A lightly oiled container, or
- A floured tray
Cover well and let them rest for:
20–30 minutes
This short rest allows the gluten to relax before the longer fermentation period.
Cold Proofing: The Secret Behind Deep Sourdough Flavour
The refrigerator is where this dough develops its personality.
Transfer the covered dough balls to the fridge and allow them to cold ferment for:
Minimum: 24 hours
Maximum: 72 hours
This slow fermentation creates:
- A deeper sourdough flavour
- Better aroma
- Improved texture
- A dough that is easier to digest for many people
The longer fermentation allows enzymes and natural bacteria to slowly transform the dough, creating more complexity.
Before Baking: Bring Dough Back to Temperature
Remove the dough from the refrigerator:
1–2 hours before shaping
The dough should:
- Feel relaxed
- No longer feel cold
- Stretch more easily without snapping back
Cold dough is tight and resistant. Giving it time to warm up makes shaping much easier.
Expert Tip:
Yes, you can.
If you need a faster option:
- Complete bulk fermentation.
- Shape your dough balls.
- Let them proof at room temperature for around 4 hours.
- Bake the same day.
The pizza will still be good, but the flavour will be milder.
For the true Pizza Portofino experience, the 24–72 hour cold ferment is worth waiting for.
Hydration Experiment: Finding The Right Sweet Spot
Hydration means the percentage of water compared to flour weight.
This recipe uses:
65% hydration
That means:
325g water ÷ 500g flour = 65% hydration
This level gives a great balance between:
- Easy handling
- Good extensibility
- A lighter crumb
- Manageable shaping
However, your ideal hydration depends on your experience and the flour you use.

Topping Preparation and Assembly
A great sourdough pizza is not only about the crust. The toppings need the same level of attention.
With Pizza Portofino, the goal is balance. The pesto brings freshness and richness. The chicken adds protein and savoury flavour. The caramelised onions bring sweetness, while the mushrooms add an earthy depth.
The key is preparing each ingredient properly before it touches the dough. Wet toppings and rushed preparation are two of the biggest reasons homemade pizza ends up with a soggy centre.
Take a little extra time here, and the final pizza will taste much closer to what you would expect from a coastal Italian kitchen.
Making the Pesto (or Choosing the Best Store-Bought Option)
Pesto is one of the defining flavours of Pizza Portofino. Since it replaces the traditional tomato sauce, its quality makes a noticeable difference.
A fresh, balanced pesto should taste:
- Bright and herbal from basil
- Nutty from pine nuts
- Rich from olive oil and cheese
- Slightly savoury from garlic
Homemade Ligurian-Style Pesto
For the closest connection to the Italian Riviera, make a simple Ligurian-inspired pesto at home.
Blend:
- 2 cups fresh basil leaves
- 2 tablespoons toasted pine nuts
- 1 garlic clove
- ½ cup grated Parmigiano Reggiano
- 2 tablespoons Pecorino Romano
- ½ cup extra virgin olive oil
- Salt to taste
Blend until smooth but avoid over-processing. Too much blending can heat the basil and slightly dull its fresh flavour.
A traditional Ligurian pesto uses Genovese basil, pine nuts, Parmigiano, Pecorino, garlic, and olive oil. These ingredients create the signature flavour that makes pesto from this region so special.
Choosing a Good Store-Bought Pesto
A quality store-bought pesto can work beautifully when you do not have time to make your own.
When shopping, check the ingredient list.
Look for:
- Genovese basil as a main ingredient
- Extra virgin olive oil
- Real Parmesan or Pecorino cheese
- Pine nuts
Try to avoid pestos where sunflower oil, artificial fillers, or unnecessary additives appear high on the list. These versions often taste flatter and less vibrant.
Some reliable options include:
- Seggiano
- Rao’s Homemade
The important thing is not the brand name. It is choosing a pesto that tastes fresh and uses quality ingredients.
Cooking the Chicken for Maximum Flavour
Chicken is one of the heartier toppings on this pizza, so it needs to stay tender. Dry chicken can quickly overpower the delicate sourdough crust and pesto flavours.
You have two good options depending on the texture you prefer.
Option 1: Grilled Chicken (More Smoky Flavour)
For a grilled version:
- Season one boneless, skinless chicken breast with:
- Salt
- Black pepper
- A drizzle of olive oil
- Grill over medium-high heat for around 6–7 minutes per side.
- Cook until the internal temperature reaches:
165°F (74°C)
- Allow the chicken to rest before slicing.
Resting is important because it keeps the juices inside the meat instead of losing them on the cutting board.
Slice or shred before adding to the pizza.
Option 2: Poached Chicken (Juicier Texture)
If you prefer softer, more delicate chicken, poaching works very well.
Add the chicken breast to gently simmering water with:
- 1 bay leaf
- A few peppercorns
Cook for around:
10–12 minutes
until fully cooked.
Then slice or shred the chicken.
This method keeps the meat moist and works especially well with the creamy pesto and mozzarella combination.
Make-Ahead Tip
Both chicken methods can be prepared one day ahead.
Store the cooked chicken in the refrigerator and bring it closer to room temperature before assembling your pizza.
Cold toppings can lower oven temperature and affect how evenly the pizza bakes.
Caramelising Onions: Patience Pays Off
Caramelised onions add natural sweetness that balances the salty cheese, savoury chicken, and tangy sourdough crust
They add a natural sweetness that balances the salty cheese, savoury chicken, and tangy sourdough crust.
The secret is simple:
Low heat and patience.
How to Caramelise Onions
- Thinly slice:
1 large onion (around 200g)
- Heat:
2 tablespoons olive oil
in a wide skillet over medium-low heat.
- Add onions with a small pinch of salt.
- Cook slowly for:
30–40 minutes
until they become deeply golden and sweet.
Stir occasionally to prevent burning.
If the onions start sticking, add a small splash of water and scrape the browned bits from the bottom of the pan. Those browned pieces contain a lot of flavour.
Optional Note: Should You Add Sugar?
A small pinch of sugar after about 20 minutes can speed up browning. However, the slower method allows the onions to develop sweetness gradually without relying on added sugar.
Natural caramelisation creates a deeper, more complex sweetness that sugar cannot fully replace.
Sautéing the Mushrooms
Mushrooms contain a lot of water, which is why preparing them before baking matters.
Adding raw mushrooms directly to pizza can release moisture during baking and make the centre soft.
For better texture:
- Heat a skillet over medium-high heat.
- Add a small amount of olive oil.
- Place sliced cremini mushrooms in a single layer.
Do not overcrowd the pan.
Cook without stirring for:
2–3 minutes
until one side becomes golden.
Then toss and cook for another:
2–3 minutes
Season with salt and pepper at the end.
Why Pan Space Matters
When mushrooms are crowded together, they steam instead of brown.
Steamed mushrooms become soft and watery.
Golden mushrooms add a deeper, roasted flavour that works beautifully with pesto and sourdough.
Layering the Pizza for the Best Bake
Once your dough is ready and your toppings are prepared, assembly becomes the final step before the oven.
The order matters.
Too many toppings or too much moisture can prevent the crust from baking properly.
Step 1: Stretch the Dough
Place the dough ball on a lightly floured surface.
Gently press from the centre outward, keeping a slightly thicker edge for the cornicione (the raised pizza crust border).
Use your fingers and knuckles to stretch the dough into a:
12-inch round
Avoid using a rolling pin.
A rolling pin pushes out the air bubbles created during fermentation. Those bubbles are what create the light, open crumb around the crust.
Step 2: Transfer to the Pizza Peel
Dust your pizza peel with:
- Semolina
- Cornmeal
Place the stretched dough on top.
Immediately give the peel a gentle shake.
The dough should slide easily.
If it sticks now, it will be much harder to fix after adding toppings.
Step 3: Add the Pesto
Spread a thin layer of pesto over the dough.
Leave around a:
1-inch border
around the edge.
Remember, pesto is rich. A little goes a long way.
Step 4: Add Cheese
Distribute torn mozzarella evenly across the pizza.
Avoid creating large piles of cheese because they can release too much moisture.
Step 5: Add the Remaining Toppings
Spread evenly:
- Cooked chicken
- Caramelised onions
- Sautéed mushrooms
Finish with:
- Toasted pine nuts
- A small amount of grated Parmigiano Reggiano
Step 6: Final Peel Check
Before baking, shake the peel one more time.
If the pizza moves freely, you are ready.
If it sticks:
- Lift the edges carefully.
- Add extra semolina underneath.
- Shake again.
Expert Tip: Less Is More
One of the easiest mistakes with homemade pizza is adding too many toppings.
A heavy pizza may look impressive before baking, but it often leads to:
- A wet centre
- Uneven cooking
- A crust that cannot rise properly
Aim for a balanced, even layer.
The crust should still be the star.
Its perforated surface helps release excess flour while the lightweight design gives you better control when sliding an assembled pizza onto a hot stone or baking steel.
Baking Instructions for Home Ovens
A home oven cannot perfectly recreate a professional pizza oven, but with the right setup, you can still achieve excellent results.
The secret is heat.
Sourdough pizza needs a strong initial burst of heat to create:
- A crisp bottom
- Puffy edges
- Blistered crust spots
- Proper cheese melting
Preheating: The Key to a Crispy Crust
Place your:
- Pizza stone, or
- Baking steel
on the middle rack of your oven.
Heat the oven to its highest temperature.
Ideally:
500°F (260°C) or higher
Preheat for at least:
45 minutes
The longer preheat allows the baking surface to fully absorb heat.
No Pizza Stone or Steel?
You can still make good pizza.
Use an upside-down heavy baking sheet.
Place it inside the oven while preheating.
It will not hold heat as efficiently as a baking steel, but it creates a much better surface than placing the pizza directly on a cold tray.
A properly heated baking surface can make one of the biggest differences in homemade pizza. A baking steel stores and transfers heat quickly, helping the base cook evenly while creating a crisp bottom and better oven spring.
This durable baking steel transfers strong, even heat directly into the dough, helping create a crisp pizza base, puffier edges, and a more restaurant-style finish in a standard home oven.
Using an Infrared Thermometer
An infrared thermometer removes the guesswork from baking pizza.
After preheating, check the surface temperature of your stone or steel.
Aim for:
550°F (288°C) or higher
If the surface is cooler, continue heating before baking.
This is especially helpful because many home ovens display a temperature that does not always reflect the actual baking surface temperature.
A useful affordable option is:
Etekcity Lasergrip 774 infrared thermometer
Transferring and Baking the Pizza
Once your oven is fully heated:
- Open the oven quickly.
- Slide the pizza from the peel onto the hot baking surface with a confident forward motion.
- Bake for:
6–8 minutes
The pizza is ready when:
- The crust is puffed
- The edges have charred spots
- Cheese is bubbling and golden
Extra Charred Finish
For a more restaurant-style crust:
Switch your oven to broil for the final:
1–2 minutes
Watch carefully.
At this stage, the pizza can move from beautifully blistered to burnt very quickly.
Expert Tip: Rotate If Needed
Most home ovens have uneven heat zones.
If one side browns faster:
- Rotate the pizza 180 degrees halfway through baking.
- Use the peel to lift and turn it carefully.
This helps create a more even crust
Troubleshooting Common Sourdough Pizza Problems
Even when you follow a sourdough pizza recipe carefully, things do not always go perfectly. The dough may feel different than expected, the crust may not rise the way you imagined, or the toppings may not behave after baking.
That is completely normal.
Sourdough is a living process. Flour, temperature, starter strength, fermentation time, and oven performance all affect the final result. Most common sourdough pizza problems can be addressed with small adjustments. The guidance below explains possible causes and practical ways to correct them
Dough Won’t Stretch and Keeps Tearing
Possible Causes
If your dough keeps shrinking back or tears when you try to stretch it, the most common reasons are:
- The gluten structure is not developed enough.
- The dough is too cold and has not relaxed.
- The dough needs more fermentation time.
A properly fermented sourdough dough should feel flexible and extensible. It should stretch gradually instead of fighting your hands.
How to Fix It
First, let the dough rest at room temperature for longer.
Give it up to:
2 hours
before shaping again.
This allows the gluten network to relax.
If the dough still feels tight:
- Perform a few additional stretch and folds.
- Let the dough rest again.
- Handle it gently during shaping.
For your next bake, try:
- Adding one extra stretch and fold set.
- Extending bulk fermentation slightly.
- Checking that your starter is reaching peak activity before mixing.
Sometimes the problem is not the dough itself — it is simply that fermentation has not done enough work yet.
Crust Is Dense Instead of Open and Light
One of the best parts of sourdough pizza is the open crumb inside the crust: those small and large air pockets created through fermentation.
If your crust feels heavy or compact, something interrupted that process.
Possible Causes
Common reasons include:
- Underfermentation.
- Too much handling during shaping.
- Not enough oven heat.
How to Fix It
Check your bulk fermentation first.
The dough should increase in volume by around:
50–75%
before shaping.
Do not rush this stage.
When shaping:
- Press gently.
- Avoid flattening the edges.
- Protect the gas bubbles you worked so hard to create.
Those bubbles are what expand in the oven and create the lighter crust.
Also check your oven temperature.
Many home ovens run cooler than the temperature displayed on the dial. A thermometer can help you confirm whether your baking surface is actually hot enough.
Toppings Slide Off When You Take a Bite
A pizza that looks beautiful but cannot hold its toppings is frustrating.
Usually, this happens because there is too much moisture or the pizza needs more baking time.
Possible Causes
- Too much pesto or cheese.
- Too many toppings.
- Cheese has not fully set.
- Pizza was sliced immediately after baking.
How to Fix It
Use a lighter hand when assembling.
Remember:
A good pizza does not need to be overloaded.
Try:
- Spreading a thinner layer of pesto.
- Using an even amount of mozzarella.
- Avoiding large piles of toppings.
Bake until:
- The cheese is fully melted.
- The surface begins to turn golden.
- The crust is properly baked.
After removing the pizza from the oven, wait about:
1 minute
before slicing.
This short rest allows the toppings to settle and makes each slice easier to handle.
Crust Burns Before the Toppings Are Cooked
This is a common issue when adapting high-temperature pizza techniques to a home oven.
The crust cooks quickly, but the toppings still need more time.
Possible Causes
- Oven temperature is too aggressive.
- Baking surface is too close to the top heating element.
- Broiler was used too early.
How to Fix It
Try these adjustments:
- Move your baking stone or steel to the middle rack.
- Avoid using broil until the final stage only.
- Watch closely during the last minutes of baking.
If your oven creates too much bottom heat, you can also try a two-stage approach:
- Bake the crust with pesto only for 2–3 minutes.
- Add toppings.
- Return the pizza to finish baking.
This gives the toppings time to cook without burning the crust.
Sourdough Flavour Is Too Mild or Too Sour
The flavour of sourdough pizza depends heavily on fermentation time and starter management.
The good news is that you can adjust the flavour based on your preference.
If the Flavour Is Too Mild
Your dough may need more fermentation time.
Try:
- Extending cold fermentation to 48–72 hours.
- Increasing the starter percentage slightly (up to around 20% of flour weight).
A longer fermentation gives the dough more time to develop those deeper sourdough flavours.
If the flavor is too sour
An overly sour pizza usually means fermentation went too far or your starter had too much accumulated acidity.
Try:
- Shortening the cold ferment to 12–18 hours.
- Feeding your starter more frequently before baking.
- Using the starter closer to peak activity instead of after it has collapsed.
A balanced sourdough flavour should be pleasantly tangy, not sharply acidic.
Baker’s Note
These troubleshooting suggestions focus on common adjustments to fermentation time, hydration level, and starter condition.
Every starter behaves slightly differently, so small adjustments are part of becoming comfortable with sourdough.
If you run into a problem that is not covered here, note what happened:
- Dough temperature
- Fermentation time
- Flour used
- Starter condition
Those details usually reveal the answer.

With a few adjustments, you can adapt this recipe to different dietary needs while keeping good texture and flavor.
Dietary Adaptations
Homemade sourdough pizza is flexible and can be adapted by changing selected ingredients while keeping the same basic method.
Whole Wheat Version
For a more rustic flavour and extra fibre:
Replace:
150g of bread flour
with:
150g whole wheat flour
Increase the water slightly to:
340g
Whole wheat flour absorbs more water, so the dough may feel firmer at first.
Expect:
- A nuttier flavour.
- A slightly denser crust.
- More complex grain notes.
This variation provides a deeper, earthier flavour and a slightly denser crust
Gluten-Free Version
A gluten-free sourdough pizza requires a different approach because there is no gluten network to create the same elasticity.
Use:
- A quality 1-to-1 gluten-free flour blend containing xanthan gum.
- Reduce water to around 300g.
- Add 1 teaspoon psyllium husk powder for improved structure.
The dough will be softer and more batter-like compared with traditional pizza dough.
For easier handling:
- Shape it directly on parchment paper.
- Transfer it to the hot baking surface with the paper underneath.
The texture will be different, but you can still create a satisfying pizza.
Dairy-Free Version
To make Pizza Portofino dairy-free:
Replace:
- Regular pesto → dairy-free pesto.
- Mozzarella → meltable plant-based mozzarella.
You can also use nutritional yeast to add a cheesy flavour.
The sourdough crust itself does not need changing, so the main texture and fermentation process remain the same.
Lower Sodium Version
To reduce sodium:
- Reduce dough salt from 10g to 7g.
- Choose low-sodium pesto or make your own with less cheese.
- Use fresh mozzarella instead of low-moisture mozzarella, which is often higher in salt.
You can still keep plenty of flavour by using:
- Fresh basil.
- Good olive oil.
- Toasted pine nuts.
- Roasted vegetables.
Portofino Pairing Guide: Wine, Salad, and Dessert
Pizza Portofino has rich flavours from pesto, cheese, chicken, and caramelised onions. The best pairings are fresh and balanced rather than heavy.
Think of the Italian Riviera:
Bright flavours. Fresh ingredients. Simple combinations.
Wine Pairing: A Crisp Ligurian White
Vermentino
Vermentino is one of the classic wines associated with the Ligurian coast.
It works beautifully because its:
- Bright acidity cuts through pesto and cheese.
- Citrus notes refresh the palate.
- Slight salinity complements seafood-inspired coastal flavours.
Look for bottles from:
- Colli di Luni
- Sardinia
Pigato
Another excellent Ligurian choice is Pigato.
Compared with Vermentino, it often has the following:
- More floral aromas.
- Almond-like notes.
- A slightly richer character.
It pairs especially well with the sweetness of caramelised onions.
Prefer Red Wine?
A lighter red can still work.
Good options include:
- Chilled Dolcetto
- Dry Lambrusco
However, a crisp white remains the more traditional match for this style of pizza.
Wine Recommendation
A bottle like La Scolca Gavi di Gavi offers a crisp, mineral profile that works nicely with pesto-based pizza.
Side Salad: Simple Arugula With Lemon
A fresh salad is the perfect contrast to a rich pizza.
Try:
- Fresh arugula
- Lemon juice
- Extra virgin olive oil
- Shaved Parmigiano Reggiano
The peppery greens and bright acidity clean your palate between bites.
For extra texture, add:
- Toasted pine nuts
- Cherry tomatoes
Keep the salad simple. The pizza should remain the centre of the meal.
Dessert: Light and Refreshing Finish
Sourdough Starter Discard Variation: Quick Same-Day Pizza Dough
Sometimes you want homemade pizza tonight, but your starter is sitting in the fridge unfed.
That is where sourdough discard comes in.
This quick version is perfect for those moments when you do not want to wait for a starter feeding schedule or a 24-hour cold fermentation.
It will not have the same deep flavour as the long-fermented Pizza Portofino dough, but it still creates a delicious sourdough-style crust with less planning.
Why Use Sourdough Discard?
Adjusted Same-Day Dough Recipe
For this version, replace the active starter from the main recipe with unfed discard.
Ingredients
Makes the same amount of dough:
- 150g sourdough discard (100% hydration, unfed)
- 500g bread flour
- 300g water
- 10g salt
- 10g olive oil
The water is reduced compared with the original recipe because the discard already contains additional liquid.
This creates a more manageable dough with around 60% hydration.
Same-Day Discard Dough Method
Step 1: Mix and Rest
Combine:
- Flour
- Water
- Sourdough discard
Mix until no dry flour remains.
Cover and let the dough rest for:
30 minutes
This shorter autolyse helps hydrate the flour and begins gluten development.
Step 2: Add Salt and Oil
Add:
- Salt
- Olive oil
Mix until fully incorporated.
The dough may feel slightly sticky at first, but it will become smoother as you develop strength.
Step 3: Stretch and Fold
Perform:
3 sets of stretch and folds
with:
20-minute intervals
Use the same gentle technique as the main recipe:
- Pull one side of dough upward.
- Fold it over.
- Rotate the bowl.
- Repeat around the dough.
Step 4: Bulk Fermentation
Allow the dough to ferment at room temperature for:
3–4 hours
Because discard is less active than a freshly fed starter, timing can vary.
Look for visual signs instead of following the clock:
The dough should become:
- Puffy
- Smoother
- Almost doubled in size
Step 5: Shape and Bake
After fermentation:
- Divide the dough.
- Pre-shape the dough balls.
- Rest for around 30 minutes.
- Shape your pizzas.
- Add toppings.
- Bake using the same oven method as the main recipe.
No cold proof is needed.
This is what makes the discard version a practical same-day option.
Expert Tip: Adding More Sourdough Character
Because discard has less fermentation power and flavour development, you can add a small amount of extra acidity if you want a stronger sourdough taste.
Try adding:
- 1–2 tablespoons plain yoghurt, or
- A small splash of apple cider vinegar
These additions help recreate some of the acidity that develops naturally during a longer fermentation.
Baker’s Note
This discard version is a practical option when homemade pizza is needed without planning a day ahead. Compared with the 24-hour fermented dough, the two versions have several noticeable differences:The long-fermented version has deeper flavour and a more complex crust.
The discard version is softer, quicker, and still genuinely satisfying.
Both have their place in a home baker’s kitchen.
Essential Tools for Sourdough Pizza Success
Great sourdough pizza does not require a huge collection of equipment.
However, a few tools make the process much easier and improve consistency.
The following tools can make sourdough dough easier to handle and help improve consistency.
The Non-Negotiables
1. Digital Kitchen Scale
A digital scale accurate to 1g is one of the most important tools for sourdough baking.
Why?
Because sourdough depends heavily on ratios.
Small differences in:
- Water
- Flour
- Starter
- Salt
can change the dough texture and fermentation.
Volume measurements like cups are much less reliable because flour can vary depending on how it is packed.
A scale gives you repeatable results every time.
2. Pizza Stone or Baking Steel
A hot baking surface is essential for creating a crisp sourdough crust.
Both options work:
3. Baking Steel
A steel transfers heat faster and usually creates a stronger oven spring.
Benefits:
- Faster heat transfer
- Crispier bottom crust
- Excellent for home ovens
4. Pizza Stone
A stone also works well when properly preheated.
The most important thing is not the material alone—it is giving it enough time to heat fully.
Always preheat your stone or steel before baking.
5. Pizza Peel
A pizza peel helps you transfer the pizza safely into the oven.
There are two common options:
6. Wooden Peel
Best for launching raw dough.
The surface is naturally less sticky and makes it easier to slide the pizza into the oven.
7. Metal Peel
Better for:
- Removing baked pizza
- Sliding underneath the finished crust
Whichever you use, lightly dust it with semolina to prevent sticking.
8. Bench Scraper
A bench scraper is a simple tool that makes sourdough handling much easier.
It helps with:
- Dividing sticky dough
- Lifting dough from the counter
- Cleaning flour and dough residue
For high-hydration dough, it quickly becomes one of the tools you reach for every bake.
Nice-to-Have Tools That Make a Difference
Recipe Guidance and Helpful Tips
Creating a successful sourdough pizza depends on understanding the key factors that influence the final result. This Pizza Portofino recipe focuses on the details that matter most, including starter activity, dough hydration, fermentation timing, and topping balance.
Rather than focusing only on measurements, this guide explains the purpose behind each step so home bakers can better understand how sourdough behaves.
Factors such as flour type, kitchen temperature, starter strength, and baking equipment can affect the dough, which is why small adjustments may sometimes be needed.
Recipe Updates and Improvements
Sourdough recipes often evolve as baking techniques, ingredient availability, and reader preferences change.
This recipe uses a 65% hydration dough, which provides a practical balance between the following:
- A dough that is easy to handle.
- Good extensibility for shaping.
- A lighter, more open crust texture.
Higher hydration doughs can create a more open crumb but may be more challenging to handle, especially for beginners. A slightly lower hydration level can make the process more approachable while still producing a flavourful sourdough crust.
Frequently Asked Questions
Pizza Portofino combines a naturally fermented sourdough crust with fresh pesto, chicken, caramelised onions, mushrooms, Parmesan, pine nuts, and basil. The crust is crisp around the edges while remaining soft and airy inside.
Use a recently fed starter that is close to its peak. It should look bubbly, airy, and noticeably risen. A weak or inactive starter can slow fermentation and produce a dense crust.
Yes. After the dough has developed and started fermenting, divide it into dough balls and refrigerate them overnight. Bring the dough out about one to two hours before shaping so it can relax and stretch more easily.
Yes. You can follow the quicker sourdough-discard variation included in this article. It is useful when you do not have time for long fermentation, although the traditional active-starter method usually provides better rise and deeper flavour.
A slightly sticky dough is normal because this recipe uses relatively high hydration. Avoid adding too much extra flour. Use lightly damp or oiled hands, and let the dough rest for 15–20 minutes if it keeps shrinking back.
Use a thick pesto and avoid applying too much. Cook the mushrooms and caramelised onions until their excess moisture has evaporated, keep the toppings light, and bake the pizza on a fully preheated stone or steel.
Yes. You can replace up to 30% of the bread flour with whole-wheat flour and add around 10–15g more water. For dairy-free pizza, use dairy-free pesto and plant-based cheese. A gluten-free flour blend containing xanthan gum can also be used, although the crust will normally be denser
Final Thoughts:
With the right preparation, sourdough pizza can become a rewarding home cooking experience.
Whether you choose the traditional long fermentation method or the quicker sourdough discard variation, the key is understanding the role of each step — from starter preparation to fermentation, shaping, and baking.
Pair your Pizza Portofino with a crisp Italian-style white wine, a fresh arugula salad, and a simple dessert like Affogato for a complete Italian-inspired meal experience.
