There is something truly magical about homemade croissants fresh from the oven. The buttery layers, the crisp golden outside, and the soft center make every bite feel special. But these Sourdough Blueberry Croissants take things to another level. They combine the rich flavor of sourdough with sweet, juicy blueberries for a bakery-style treat you can make right at home.

These croissants are not only delicious but also easier on digestion thanks to the sourdough fermentation process. They feel lighter, more flavorful, and wonderfully homemade. Whether you are baking for family, brunch guests, or simply treating yourself, these flaky blueberry croissants are always worth it.

Ingredients for Sourdough Blueberry Croissants
For the Dough
- 4 cups bread flour
- 1 cup active sourdough starter
- 1 cup warm milk
- 1/4 cup sugar
- 2 large eggs
- 1 teaspoon salt
- 3 tablespoons unsalted butter, softened
For the Butter Layers
- 1 cup cold unsalted butter
For the Blueberry Filling
- 1 cup fresh blueberries
- 2 tablespoons sugar
- 1 teaspoon cornstarch
- 1 teaspoon lemon juice
For the Egg Wash
- 1 egg
- 1 tablespoon milk
Step-by-Step Instructions
Step 1: Prepare the Dough
In a large mixing bowl, combine the sourdough starter, warm milk, sugar, eggs, and softened butter. Mix well.
Add the flour and salt slowly while stirring until a dough forms.
Knead the dough for about 8–10 minutes until smooth and soft.
Helpful Tip
The dough should feel slightly soft but not sticky. Add a little flour if needed.
Step 2: Let the Dough Rise
Place the dough into a lightly greased bowl. Cover and let it rise overnight or for 8–10 hours at room temperature.
The dough should almost double in size.
Why This Step Matters
Slow fermentation gives these Sourdough Blueberry Croissants their rich flavor and airy texture.
Step 3: Prepare the Butter Block
Place the cold butter between two sheets of parchment paper. Use a rolling pin to flatten it into a square shape.
Refrigerate until firm but still flexible.
Step 4: Laminate the Dough
Roll the dough into a large rectangle. Place the butter block in the center and fold the dough over it like an envelope.
Roll the dough gently into a rectangle again. Fold into thirds like a letter.
Chill for 30 minutes.
Repeat this rolling and folding process 3 times.
Helpful Tip
Keep the dough cold during this process. Warm butter can leak out and ruin the flaky layers.
Step 5: Make the Blueberry Filling
In a small bowl, mix the blueberries, sugar, cornstarch, and lemon juice.
The cornstarch helps thicken the filling during baking.
Step 6: Shape the Croissants
Roll the dough into a large rectangle about 1/4 inch thick.
Cut triangles using a sharp knife or pizza cutter.
Place a spoonful of blueberry filling near the wide end of each triangle.
Roll tightly toward the tip to form croissant shapes.
Step 7: Final Rise
Place the croissants on a lined baking tray.
Cover loosely and let them rise for 2–3 hours until puffy.
Step 8: Brush and Bake
Preheat your oven to 400°F (200°C).
Whisk together the egg and milk for the egg wash. Brush over each croissant.
Bake for 18–22 minutes until deeply golden brown.
Let them cool slightly before serving.
