Let’s Get Cooking!
Feed Your Sourdough Starter
First things first, a couple of hours before you start, make sure your sourdough starter is ready! You’ll want 150 grams of active, mature sourdough starter. This means it should have been fed equal parts flour and water within the past 4-6 hours and be bubbly and alive!
If you’re down to the last bit of starter, just combine 50 grams of sourdough starter, 50 grams of flour, and 50 grams of water in a glass jar. This way, you can have the perfect amount ready while still having some extra for your bread-making adventures later!
Make, Knead, and Proof the Dough
Once your starter is a happy little bubble factory, it’s time to get mixing! In a bowl, whisk together your sourdough starter, melted unsalted butter, filtered water, and whole milk until combined. Now, add in the organic unbleached flour, granulated sugar, and sea salt.
Using your hands or a dough whisk, mix it all until it forms a shaggy dough. Cover the bowl with a clean kitchen towel and let it rest for 30 minutes. Trust me, this rest is crucial!
After 30 minutes, flip your dough out onto a clean counter, no flour needed here! Knead it for about 3-5 minutes until it’s smooth, stretchy, and no longer sticky. It should feel a bit like a soft pillow!
Now, transfer it to a butter-greased glass bowl, cover it with plastic wrap, and allow it to rise at room temperature until it has doubled in size, about 4-6 hours.
Once it’s all puffed up, pop the dough in the fridge for slow fermentation for a minimum of 12 hours. Honestly, you can leave it in there for up to 3 days. Just keep it covered so it doesn’t dry out.
Le Beurrage (Butter Filling)
On the day you’re ready to bake, grab your high-fat, unsalted butter. It’s important to start with room temperature butter here for easy manipulation.
Fold a piece of parchment paper into an 8×8 square packet. Lay butter slices, about 1/4 inch thick onto the bottom half of the paper. Fold it back up and roll it with a rolling pin into all corners. This is your le beurrage!
Chill the butter packet in the fridge for 6 minutes until it’s cool but not hard. You want it pliable since it’ll be rolled into the dough.
Laminate the Dough
Time to pull that cold dough out of the fridge! Place it on a lightly floured surface and roll it out to an 8×17 rectangle. Your dough should be just slightly longer than your butter packet.
Unwrap your butter and place it on the bottom half of the dough. Fold the top half down over the butter so the edges meet. Now, turn the dough 90 degrees and roll it to about 18 inches long. Flour your surface well—it’s essential to avoid any stickiness here.
Fold Again for Layering
Once rolled, fold the top part of the dough down about two-thirds of the way, bringing the bottom part up to meet it. Then fold in half again, this creates a nice, compact rectangle. Now, turn the dough 90 degrees and roll it out to about 20 inches long again.
Now we’re at the last fold! Fold the top part of the dough down about two-thirds of the way, and then bring the bottom part all the way up over it, like a pamphlet. At this point, if the butter or dough is starting to get too warm, chill it for about 10 minutes before proceeding.
Once again, roll out that dough into a final rectangle, making it approximately 8×24 inches.
Shape Your Croissants
Trim the edges of your dough for clean lines. On the longer side, mark every 3.5 inches, these will be your triangles. Then, make a diagonal mark in the middle of each.
Cut the dough into triangles and then grab one triangle, starting at the wider end, roll it towards the point, gently stretching it as you go. Lay the croissant on a parchment-lined baking sheet with the point facing down.
Repeat for the remaining triangles. You should end up with about 10-12 croissants depending on your cuts!
Proofing Time
Now, whisk an egg and brush it gently over your croissants, this will help keep them moist while they double in size. Cover with a clean towel and let them proof in a spot without drafts for about 2-4 hours. An unheated oven is perfect for this, just remember not to turn it on!
Bake These Little Beauties!
When your croissants have doubled, preheat the oven to 380°F. Give them another quick brush of the egg wash, then place them in the oven. Bake for 25-30 minutes until golden brown and heavenly.
And here’s the best part: when they come out, let them rest on the baking sheet for about 15 minutes undisturbed, this is essential! The rest time allows them to finish baking inside, plus it gives you that magical flaky quality.

Why I Love This Recipe
This is my go-to recipe when I have a craving for baked goods but don’t have the hours to spare. I mean, is there anything better than the smell of freshly baked croissants wafting through your home?

Serving & Storage Tips
Now that you’ve created these incredibly delicious croissants, let’s talk about serving and storage!
Serving Suggestions
These croissants are perfect as is, but you can serve them warm with a spread of butter, jam, or even a drizzle of honey for added sweetness. They pair beautifully with coffee or tea for a delightful breakfast or afternoon treat!
Storage
If you have any leftover croissants (though I doubt it!), you can store them in an airtight container at room temperature for up to 2 days. They may lose a bit of their crispiness, but the flavor will still be divine.
Reheating Instructions
To reheat, simply pop them in a preheated oven at 350°F for about 5-7 minutes, this will help crisp them up again.
Freezer-Friendly? Yes!
You can definitely freeze these croissants as well! Just wrap them tightly in plastic wrap and store them in a freezer-safe bag for up to 3 months. When you’re ready to enjoy, thaw them overnight in the fridge, then reheat as mentioned above.
