Ingredients You’ll Need

This Sourdough Croissants Made with Sourdough Starter Recipe uses simple, wholesome ingredients that work together beautifully to create that perfect buttery and flaky delight. Each component plays a key role in the structure, flavor, and crumb of the croissants, so I always like to choose the best quality I can find.

• 150 grams active sourdough starter: Your flavor powerhouse, it provides the natural fermentation and subtle tang.
• 113 grams filtered water: Keeps dough hydrated without impurities that can affect rising.
• 113 grams whole milk: Adds richness and tenderness to the crumb.
• 50 grams butter, melted: Gently enriches the dough, enhancing softness.
• 450 grams organic unbleached all-purpose flour: Gives the dough structure with excellent gluten.
• 45 grams granulated sugar: Adds just enough sweetness to balance the sourdough tang.
• 9 grams sea salt: Amplifies flavors and controls fermentation.
• 250 grams unsalted butter, room temperature: Essential for the lamination to create those iconic flaky layers.

Directions

Step 1: Begin by feeding your sourdough starter so it’s vibrant and bubbly. You need 150 grams of active starter that has doubled within 4-6 hours after feeding. If you want to reserve some starter separately, mix 50 grams starter with 50 grams flour and 50 grams water in a jar.

Step 2: Whisk together the active sourdough starter, melted butter, filtered water, and whole milk in a large bowl. Then add the flour, sugar, and salt. Use your hands or a dough whisk to mix until a cohesive dough forms. Cover and let it rest for 30 minutes to hydrate and relax.

Step 3: Turn the dough onto a clean surface (no flour needed) and knead for 3-5 minutes until smooth and no longer sticky. Place the dough in a buttered bowl, cover with plastic wrap or beeswax wrap, and allow it to bulk rise at room temperature until doubled and puffy—about 4 to 6 hours.

Step 4: After the bulk rise, refrigerate the dough for at least 12 hours to continue fermenting slowly. You can leave it up to 3 days, ensuring it stays covered to prevent drying out.

Step 5: Prepare the butter filling or le beurrage by folding parchment paper into an 8×8 inch square packet. Slice 250 grams unsalted butter at room temperature to about 1/4 inch thick and lay the slices on the parchment, folding to enclose the butter. Roll it into corners and spaces so it forms a neat packet. Chill in the fridge for about 6 minutes until pliable but not hard.

Step 6: Remove the dough from the fridge and roll it into an 8×17 inch rectangle on a floured surface. Place the beurrage on the bottom half and fold the top of the dough over the butter, sealing the edges.

Step 7: Turn the dough 90 degrees and roll it out to about 18 inches in length. Keep the surface floured to prevent sticking.

Step 8: Fold the top third of the dough down, then fold the bottom third up over it to create a square. Fold this square in half, then turn the dough 90 degrees and roll it lengthwise to about 20 inches.

Step 9: For the last fold, fold the top two-thirds of the dough down, then bring the bottom part over it in a pamphlet style fold. If needed, chill the dough wrapped in plastic for 10 minutes to keep butter solid but pliable.

Step 10: Roll out the dough to an 8×24 inch rectangle, trimming edges for clean lines. Mark every 3 1/2 inches on the long side and make intermediary marks on the opposite side in a zig-zag pattern, then slice triangles along those lines.

Step 11: Roll each triangle starting from the wide end to the point to form croissants. Place them point-down on a parchment-lined baking sheet to avoid unrolling during proof.

Step 12: Brush croissants lightly with whisked egg wash and cover. Let them proof in a warm, draft-free place for 2-4 hours until doubled.

Step 13: Preheat your oven to 380°F. Give the croissants a final brush with egg wash and bake for 25-30 minutes until a deep golden brown.

Step 14: Let croissants rest on the baking sheet for 15 minutes after baking to allow butter to reabsorb and layers to set. Then dig in and savor every flaky, buttery bite!

Servings and Timing

This recipe yields roughly 10 to 12 croissants, perfect for sharing with family or treating yourself to several days of flaky bliss. Prep time, including dough mixing and folding, takes about 45 minutes spread across multiple stages. Bulk fermentation requires about 4-6 hours at room temperature, followed by a minimum 12-hour cold fermentation in the fridge. Proofing takes another 2-4 hours, with a bake time of 25-30 minutes. Altogether, you’re looking at around 25 hours from start to finish, mostly hands-off, but with glorious patience rewarded at the end.

How to Serve This Sourdough Croissants Made with Sourdough Starter Recipe

When it comes to serving these croissants, I love to keep things simple so the flavors can truly shine. Warm them slightly just before serving to bring out the buttery aroma and flaky texture. I like to serve them alongside a selection of creamy cheeses, fresh berries, and honey for a vibrant brunch spread. For a savory option, sliced ham or smoked salmon with a dab of crème fraîche make a lovely pairing.

Presentation can be as charming as the pastries themselves. Arrange the croissants in a rustic basket lined with a soft linen napkin, and garnish with fresh herbs like thyme or edible flowers for a touch of elegance. If you’re serving at a holiday brunch or special occasion, a small bowl of homemade jam or a sprinkled dusting of powdered sugar adds refinement and invites guests to customize their bites.

Beverage pairings I adore include a light, crisp sparkling wine or a freshly brewed latte. On cooler mornings, a chai tea or rich hot chocolate also complements the croissant’s buttery richness beautifully. This recipe is perfect for festive gatherings, lazy weekend breakfasts, or even a weeknight treat—you can never go wrong serving warm, homemade sourdough croissants that feel like a special gift to yourself and your loved ones.

Variations

I love experimenting with this Sourdough Croissants Made with Sourdough Starter Recipe by adding a personal twist here and there. If you want a richer dough, swap the whole milk for heavy cream or half-and-half. For a touch of sweetness, sprinkle cinnamon sugar inside before rolling up the triangles. You could also spread a thin layer of chocolate or almond paste for an indulgent almond or pain au chocolat version that never fails to impress.

For those with dietary restrictions, I’ve found some success using dairy-free butter alternatives for a vegan twist, though be warned this may slightly affect the lamination and flakiness. Gluten-free croissants can be trickier because of gluten’s role in structure, but using a high-quality gluten-free flour blend and adding extra hydration can help. Patience and attention to dough texture become even more crucial here.

Different cooking methods could be explored too—I sometimes heartily recommend trying a convection oven bake for more even browning or experimenting with reduced baking temperature for extra tenderness, though these tweaks might shift baking times slightly. Regardless of the variation, the essence and magic of sourdough fermentation remain the centerpiece.

Storage and Reheating

Storing Leftovers

After enjoying your fresh croissants, any leftovers can be stored in an airtight container at room temperature for up to two days. To keep them from losing their crisp exterior, I recommend wrapping them loosely in parchment paper or using a paper bag inside a sealed container to maintain the flaky texture without trapping moisture. Avoid plastic wrap directly around them as this can make the crust soggy.

Freezing

These sourdough croissants freeze beautifully, which is a lifesaver for busy mornings. Let them cool completely, then wrap each croissant tightly in plastic wrap and place them in a freezer-safe zip-top bag or airtight container. They keep well frozen for up to two months. When you want to enjoy one, simply thaw at room temperature for a couple of hours or overnight in the fridge.

Reheating

To bring back that fresh-from-the-oven flakiness, reheat croissants in a preheated oven at 350°F for 5-10 minutes. This warms them through and crisps the outer layers without drying out the crumb. I avoid microwaving, as it tends to turn croissants chewy and limp. For a quicker teaser, a toaster oven also works wonders to revive the delicate layers and buttery scent.

FAQs

What if my sourdough starter isn’t very active?

If your starter hasn’t doubled or become bubbly after feeding, it might not provide enough rise or flavor complexity. I suggest feeding it for a day or two until it’s lively and vigorous before starting the croissants. A healthy starter makes all the difference!

Can I use all-purpose flour instead of bread flour?

Yes, I use organic unbleached all-purpose flour in this recipe because it strikes a great balance between structure and tenderness for croissants. Bread flour is higher in protein and might create a chewier texture, so I recommend sticking with all-purpose for best results.

How important is the butter temperature for lamination?

The butter needs to be room temperature but still cool and pliable—not melted. Too cold and it cracks, too warm and it melts into the dough, losing the laminated layers. The slight chill after forming the butter packet helps maintain perfect consistency for rolling out.

Can I make the dough and freeze it before laminating?

While you can freeze croissant dough, I find that fresh lamination yields the best flakiness. If you do freeze, thaw slowly in the fridge overnight before shaping and proofing. This requires some trial but can save prep time on busy days.

How do I know when the croissants are proofed and ready to bake?

They should roughly double in size and feel puffy and pillowy. A gentle poke should slowly spring back without deflating completely. Patience during proofing is key for those signature airy layers inside.

Conclusion

Making Sourdough Croissants Made with Sourdough Starter Recipe is one of my favorite ways to blend the timeless art of sourdough with the decadent pleasure of flaky pastries. It requires a little patience and love, but the payoff is truly spectacular—a buttery, gently tangy croissant that’s far superior to anything store-bought. I encourage you to give this recipe a go and discover the joy of creating your own buttery layers at home. Your mornings will never be the same again!
