Artisanal Flaky Buttery Sourdough Croissants deliver bakery-level bliss in your own kitchen, combining tangy sourdough and rich layers of cold butter for golden crescents that crackle with every bite—it’s the perfect advanced weekend project for anyone who loves artisan baking and flaky pastry.
Key Ingredients
Before you begin laminating and shaping, gather these staples for your dough and layers:
- 500 g all-purpose flour: Provides structure for the laminated dough and holds the layers together.
- 100 g active sourdough starter: Brings a tangy flavor and natural leavening to create an airy, open crumb.
- 50 g granulated sugar: Adds a touch of sweetness and helps with browning.
- 10 g salt: Balances the flavors and strengthens gluten development.
- 250 ml cold water: Hydrates the dough and keeps it cool for proper lamination.
- 250 g unsalted butter: Creates the rich, flaky layers when folded into the dough.
- 1 unit egg: Used for the egg wash to give croissants a shiny, golden crust.
- 15 ml milk: Mixed with egg to lighten the wash and improve color.
- 100 g flour for dusting: Prevents sticking during rolling and folding.
How To Make Artisanal Flaky Buttery Sourdough Croissants
This recipe takes you through each step—from mixing and kneading to the multiple folds that create dozens of delicate layers—culminating in perfectly proofed croissants with a crisp, golden finish. With careful chilling and the classic letter fold technique, you’ll build that signature flaky texture before brushing on an egg wash and baking to buttery perfection.
1. Combine the flour, sugar, and salt in a large bowl and use a whisk to ensure the dry ingredients are evenly distributed and free of clumps.
2. Stir in the active sourdough starter and cold water, then mix with a sturdy spoon or your hands until a rough, cohesive dough comes together.
3. Turn the dough onto a lightly floured work surface and knead for about 5 minutes, working the dough until it feels smooth and elastic.
4. Form the dough into a flat disc, wrap it tightly in plastic wrap, and chill in the refrigerator for 1 to 2 hours to relax the gluten.
5. Place the unsalted butter between two sheets of parchment paper and gently pound and roll it into a thin, even square; then refrigerate until firm.
6. On a floured surface, roll the rested dough into a rough rectangle large enough to encase the butter square, then center the chilled butter on top.
7. Fold the dough edges over the butter, enclosing it completely; then use a rolling pin to gently roll the sealed packet into a long rectangle.
8. Execute a classic letter fold: fold one third of the dough toward the center and fold the opposite third over it, creating multiple layers.
9. Wrap the folded dough in plastic wrap, chill for 30 minutes, then repeat the rolling and letter fold process two more times, chilling between each.
10. After completing the third fold, wrap the dough securely and refrigerate overnight to develop flavor and strengthen the dough.
11. Take the chilled dough out, roll it into a large rectangle, then cut it into equal-sized triangles. Starting at the wide end, roll each triangle into the classic croissant crescent.
12. Place the shaped croissants on a parchment-lined baking sheet, cover loosely, and let them proof at room temperature for 2 to 3 hours, until puffy.
13. Preheat your oven to 200°C. In a bowl, whisk together the egg and milk to prepare your egg wash.
14. Gently brush each croissant with the egg wash, then bake in the preheated oven for 15 to 20 minutes, or until deeply golden brown.
15. Remove the croissants and transfer them to a wire rack to cool slightly—this preserves crispness—before enjoying.

Tips For Perfect Artisanal Flaky Buttery Sourdough Croissants
Mastering these croissants is all about temperature control and patience. Keeping ingredients cold and respecting resting times ensures those gorgeous flaky layers won’t fuse together or leak in the fridge. Ambient warmth can speed up or slow down your rise, so adjust proofing until your crescents are visibly airy, not just passive dough logs. Finally, loading your oven’s surface properly will give extra crispness to that tender crumb below. Now, let’s nail those details:
- Use very cold butter to maintain distinct flaky layers.
- Ensure proper chilling between folds to prevent butter leakage.
- Proofing time may vary depending on ambient temperature.
- Bake on a preheated tray or stone for a crispier crust.
How To Store It
Leftover croissants are just as delightful reheated, but storing them properly is key to preserving that fresh-out-of-the-oven taste. From quick fridge holding to long-term freezing, follow these methods to extend their life while maintaining crunch and flavor.
- Room Temperature: Keep cooled croissants in an airtight container at room temperature for up to 2 days, ensuring they stay tender inside.
- Refrigeration: Store in a resealable plastic bag or container in the fridge for up to 4 days; gently reheat in a warm oven to revive crispness.
- Freezing: Wrap each croissant tightly in plastic wrap and place in a freezer bag. Freeze up to 1 month, then bake directly from frozen on a preheated tray.
- Reheating: To refresh refrigerated or frozen croissants, heat at around 160°C for about 5–10 minutes until warm and flaky.
Frequently Asked Questions
Here are quick answers to help you master your sourdough croissant adventure:
- What type of sourdough starter should I use and how do I ensure it's active enough?
Use a mature, 100% hydration sourdough starter that has been fed and doubled within 4–6 hours; it should be bubbly and aromatic. Weigh out 100 g of starter and mix it directly with the cold water into your dry ingredients for optimal fermentation and rise.
- Why is it important to keep the butter and dough cold, and how cold should they be?
Cold ingredients prevent the butter from melting into the dough, preserving distinct flaky layers. The butter block should be firm but pliable straight from the fridge, and the dough should be chilled at around 4 °C for 30 minutes between each fold and for 1–2 hours before enclosing the butter.
- How do I know when the dough has been kneaded and folded enough?
After about 5 minutes of kneading on a lightly floured surface, the dough should feel smooth and elastic, no longer sticky. Each of the three letter folds—followed by 30 minutes of chilling—should create visible layers. After the final overnight chill, you should see six to eight even butter layers when you roll the dough out.
- How can I tell when the shaped croissants are properly proofed before baking?
Properly proofed croissants will appear noticeably puffy, about 1.5 times their original size, and yield slowly when gently pressed—they should spring back just a bit. Proofing typically takes 2–3 hours at room temperature but varies with ambient warmth.
- What is the purpose of the egg wash and how do I apply it?
The egg wash—a mixture of one beaten egg and 15 ml milk—gives the croissants a shiny, golden-brown crust. Just before baking, brush the proofed croissants evenly with the wash, making sure not to deflate them.
- How can I achieve a crispier crust on my croissants?
Bake on a fully preheated tray or baking stone at 200 °C. The direct heat from the surface helps crisp the bottom, while avoiding opening the oven door during the first 10 minutes preserves steam and encourages a strong oven spring.
