Ingredients

For the Dough

500g bread flour
350g water (room temperature)
100g active sourdough starter
10g sea salt

Blueberry Filling

1½ cups fresh blueberries (or frozen)
2 tablespoons sugar
1 teaspoon lemon juice
1 teaspoon cornstarch (optional, helps reduce extra moisture)

Optional:

1 teaspoon vanilla extract
½ teaspoon cinnamon
Lemon zest

Equipment Needed

Digital kitchen scale
Dutch oven
Banneton basket
Dough scraper
Mixing bowl
Sharp bread lame or razor blade
Cooling rack

Step 1: Feed Your Starter

Feed your sourdough starter about 4–6 hours before mixing your dough. Your starter should be bubbly, active, and able to double in size before using.

A healthy starter is the key to getting a light, airy loaf.

Step 2: Mix the Dough

In a large bowl combine:

Bread flour
Water
Active starter

Mix until no dry flour remains.

Cover and let rest for 30 minutes.

This rest is called the autolyse and helps develop gluten naturally.

Step 3: Add Salt

Sprinkle the salt over the dough.

Wet your hands and squeeze the dough until the salt is fully incorporated.

Cover again.

Step 4: Stretch and Fold

Over the next two hours perform four sets of stretch and folds every 30 minutes.

Grab one side of the dough.

Stretch upward.

Fold over itself.

Rotate the bowl and repeat until all four sides are folded.

You’ll notice the dough becoming smoother and stronger after every fold.

Step 5: Prepare the Blueberries

If using frozen blueberries, do not thaw them.

If using fresh berries:

Mix together:

Blueberries
Sugar
Lemon juice
Cornstarch

Let sit for 10 minutes.

This helps release a little juice while keeping the filling from becoming overly wet.

Step 6: Add the Blueberries

After your final stretch and fold, gently flatten the dough.

Scatter one-third of the blueberries across the surface.

Fold the dough.

Repeat until all blueberries are incorporated.

Avoid overmixing since crushed berries can make the dough too wet.

Some streaks of purple are completely normal and make the finished loaf look beautiful.

Step 7: Bulk Fermentation

Cover the dough.

Allow it to ferment at room temperature for 4–6 hours.

The dough should become puffy, smooth, and increase by about 50%.

The exact time depends on your kitchen temperature.

Step 8: Shape the Dough

Lightly flour your work surface.

Turn out the dough carefully.

Shape it into a tight round or oval loaf while keeping as many blueberries inside the dough as possible.

Let it rest for 20 minutes.

Then perform the final shaping.

Step 9: Cold Proof

Place the shaped dough seam-side up in a floured banneton basket.

Cover well.

Refrigerate overnight for 10–14 hours.

Cold proofing develops deeper sourdough flavor while making scoring much easier.

Step 10: Preheat

Place your Dutch oven inside the oven.

Preheat to 475°F (245°C) for at least 45 minutes.

A thoroughly heated Dutch oven creates incredible oven spring.

Step 11: Score the Bread

Remove the dough from the refrigerator.

Invert onto parchment paper.

Dust lightly with flour.

Use a bread lame to score the loaf.

You can make a simple center slash or create decorative wheat designs like artisan bakeries.

Step 12: Bake

Transfer the dough into the hot Dutch oven.

Cover with the lid.

Bake:

20 minutes with the lid on
Remove the lid
Bake another 20–25 minutes until deep golden brown

The bread should have a crisp crust and an internal temperature of about 208–210°F (98–99°C).

Step 13: Cool

Move the loaf to a cooling rack.

Allow it to cool for at least one hour before slicing.

Although it’s tempting to cut into it immediately, cooling allows the crumb to finish setting and prevents it from becoming gummy.

Flavor Variations

Try customizing your loaf with different add-ins:

White chocolate chips
Lemon zest
Cinnamon swirl
Cream cheese filling
Chopped walnuts
Pecans
Orange zest
Honey drizzle
Vanilla bean paste

Each variation creates a unique artisan loaf.

Serving Suggestions

Blueberry sourdough is delicious served with:

Salted butter
Honey
Cream cheese
Whipped ricotta
Strawberry jam
Blueberry preserves
Peanut butter
Almond butter

It also makes excellent French toast or grilled breakfast sandwiches.

Storage Tips

Store the loaf in a paper bag or bread box for up to 3 days at room temperature. For longer storage, wrap the cooled loaf tightly and freeze for up to 3 months. Thaw at room temperature and refresh in a 350°F oven for 8–10 minutes to restore the crisp crust.

Pro Tips for Success

Use a bubbly, active sourdough starter for the best rise.
Avoid adding too many blueberries, as excess moisture can make the dough difficult to handle.
Frozen blueberries can help reduce juice bleeding during shaping.
Cold-proofing overnight improves flavor and makes decorative scoring easier.
Bake in a preheated Dutch oven for maximum oven spring and a crisp crust.
Let the bread cool completely before slicing for the best texture.

Frequently Asked Questions

Yes. Add them directly from the freezer without thawing to prevent excess moisture.

Can I make this recipe sweeter?
Absolutely. Increase the sugar in the filling or drizzle the finished loaf with a simple glaze for a dessert-style bread.

Why is my dough purple?
Some blueberries naturally burst during folding and fermentation. The purple streaks are normal and give the bread its signature artisan look.

Can I freeze the loaf?
Yes. Freeze the whole loaf or individual slices in an airtight bag for up to 3 months.

What flour works best?
High-protein bread flour provides the strongest gluten structure and creates a chewy, bakery-style crumb.
