Homemade Sourdough Croissants Recipe
Few baked goods are as impressive and satisfying as homemade sourdough croissants. With their flaky golden layers, crisp buttery exterior, and soft airy interior, croissants are a true bakery classic. Adding sourdough starter to the dough gives these croissants deeper flavor, a slight tang, and incredible texture that cannot be matched by commercial yeast alone.
Making sourdough croissants at home takes patience, but the results are absolutely worth it. The process involves creating buttery laminated layers that puff beautifully during baking, creating those iconic honeycomb interiors and delicate flaky crusts.
Whether you are an experienced baker or trying laminated dough for the first time, this detailed sourdough croissant recipe will guide you through every step for bakery-quality results.

What Are Sourdough Croissants?
Sourdough croissants are laminated pastries made with sourdough starter instead of instant yeast. The dough is layered repeatedly with butter through a folding process called lamination.
As the croissants bake, steam forms between the butter layers, creating the signature flaky texture and airy structure.
Compared to standard croissants, sourdough croissants offer:
- More complex flavor
- Slight tanginess
- Better texture
- Longer freshness
- Natural fermentation benefits

How to Make Homemade Sourdough Croissants
Step 1: Mix the Dough
In a large bowl, combine:
- Bread flour
- Milk
- Active sourdough starter
- Sugar
- Salt
- Softened butter
Mix until a rough dough forms.
Knead for about 8–10 minutes until smooth and elastic.
Step 2: Bulk Fermentation
Place the dough in a lightly greased bowl.
Cover and let ferment at room temperature for 4–6 hours until slightly puffy.
Transfer to the refrigerator overnight.
Cold dough is much easier to laminate.
Preparing the Butter Block
Step 3: Shape the Butter
Place the cold butter between two sheets of parchment paper.
Roll into a rectangle about:
20 cm×20 cm
Refrigerate until firm but still pliable.
Laminating the Dough
Step 4: Roll Out the Dough
Roll the chilled dough into a rectangle roughly twice the size of the butter block.
Place the butter block in the center.
Fold the dough over the butter like an envelope, sealing the edges completely.
Step 5: First Fold
Roll the dough into a long rectangle.
Fold it into thirds like a letter.
Wrap and refrigerate for 30–45 minutes.
Step 6: Repeat the Folding Process
Repeat the rolling and folding process two more times, chilling between each fold.
This creates the beautiful flaky layers.
Shaping the Croissants
Step 7: Roll and Cut
Roll the dough into a large rectangle about:
0.5 cm thickness
Cut long triangles using a sharp knife or pizza cutter.
Step 8: Shape the Croissants
Starting from the wide end, roll each triangle tightly toward the tip.
Curve the ends slightly inward to create the classic crescent shape.
Place on parchment-lined baking trays.
Final Proofing
Step 9: Proof the Croissants
Cover loosely and allow to proof until noticeably puffy and jiggly.
This usually takes:
- 3–5 hours at room temperature
The croissants should nearly double in size.
Baking the Sourdough Croissants
Step 10: Preheat the Oven
Preheat oven to:
375∘F≈190∘C
Step 11: Apply Egg Wash
Whisk together the egg and milk.
Brush gently over the croissants.
This creates a shiny golden crust.
Step 12: Bake
Bake for:
- 20–25 minutes
Until deeply golden brown and crisp.
The internal layers should look airy and well-risen.
Tips for Perfect Sourdough Croissants
Keep Everything Cold
Warm butter melts into the dough and ruins layering.
Use European Butter
Higher-fat butter creates superior flaky layers.
Don’t Rush the Proof
Underproofed croissants will be dense.
Avoid Excess Flour
Too much flour during rolling toughens the dough.
Chill Between Folds
Resting keeps the butter and dough at the correct consistency.
Signs Your Croissants Are Properly Proofed
Well-proofed croissants should:
- Jiggle slightly when shaken
- Feel airy and light
- Show visible layers
- Expand noticeably
Proper proofing is essential for large honeycomb interiors.
Common Croissant Problems and Solutions
Butter Leaking During Baking
Usually caused by warm dough or broken butter layers.
Dense Interior
Often due to underproofing.
Croissants Not Rising
Your sourdough starter may not have been active enough.
Tough Texture
Overhandling or excess flour can make croissants chewy.
