Baking Croissants from Dough
If you've already laminated and shaped your dough, baking is straightforward—but the final proof matters as much as oven temperature. Underproofed croissants bake dense and pale. Overproofed ones collapse. The window is real, and you'll feel the difference the moment you bite into one.
You need shaped, chilled croissant dough ready to proof
This guide assumes you've already laminated, folded, cut, and shaped your dough. If you're starting from scratch, you'll need 2–3 days total. Croissants must go into the oven cold or room-temperature after final proof—never warm. A cold oven will bake the outside before the inside rises.

What goes in.
- 12shaped croissant dough pieces, chilled or at room temperature after final proof
- 1egg, beaten (for egg wash)
- pinchsalt (for egg wash)
Reading the final proof
Croissants are ready to bake when they're visibly puffy and jiggly—not rock-hard, not flat. Poke one gently with your finger. It should bounce back slowly, leaving a slight indent. If it springs back instantly, it needs more time. If it doesn't spring back at all, you've overproofed and the oven won't save it.
The method.
Final proof your shaped croissants
Place shaped dough on a parchment-lined sheet pan. Cover loosely with plastic wrap or a kitchen towel. Let them proof at room temperature (68–72°F) for 60–90 minutes, or until visibly puffy and soft to a gentle poke. In a warm kitchen, they may be ready in 45 minutes. In a cool one, they'll need the full 90. Patience here determines everything.
Preheat your oven to 400°F
Do this about 15 minutes before you expect the croissants to be ready. The oven must be fully hot. Use an oven thermometer if you don't trust your dial—off-by-25-degrees changes the bake.
Apply egg wash
Whisk egg with a pinch of salt. Brush gently over each croissant—one light coat, not heavy. Egg wash gives you that glossy, mahogany finish. Be gentle so you don't deflate the dough.
Bake at 400°F for 18–22 minutes
Set a timer for 18 minutes and check. Croissants are done when the top is deep golden brown and the sides show color all the way down. The bottom should be a shade darker than the top but not charred. If they're pale at 18 minutes, give them 2–3 more. Every oven is different. Rotate the pan halfway through if your oven has hot spots.
Cool on the pan for 2–3 minutes, then transfer to a rack
They'll firm up as they cool. The interior is still steaming. If you wrap them too soon, the steam makes them soft. Let them sit uncovered for at least 10 minutes before serving or storing.
Other turns to take.
Chocolate croissants (pain au chocolat)
Before shaping, place a stick of dark chocolate on the dough rectangle, roll it up, then cut and proof as usual. The chocolate melts into the layers during baking. Use good chocolate—it matters more here than in most recipes.
Almond croissants
After egg wash, sprinkle sliced almonds and a light dusting of pearl sugar on each croissant. The nuts toast in the oven and the sugar stays visible on top.
Mini croissants
Cut your dough into smaller triangles before shaping. They bake in 14–16 minutes and proof in 45 minutes. Useful if you want to serve a lot or test your technique on smaller batches.
When it doesn't go to plan.
Don't skip the final proof. It's the difference between a dense log and a flaky pastry. Underproofed croissants are the most common mistake at the baking stage.
If your kitchen is very cold, proof your croissants in an off oven with the light on, or near (not on) a warm radiator. Aim for 70°F.
Egg wash is optional but gives you color control. Without it, croissants are paler and matte. They taste the same.
Croissants are best eaten within a few hours of baking, but they keep for a day in an airtight container at room temperature. Refrigerate them and they dry out. Freeze unbaked, shaped dough for up to 3 weeks—bake from frozen, adding 5–7 minutes to the bake time.
If croissants are browning too fast on top but the interior isn't done, tent them loosely with foil for the last 5 minutes.

How do I know if my croissants are proofed enough?
Poke one gently with your finger. It should feel puffy and give slightly to pressure, then slowly bounce back, leaving a faint indent. It should jiggle when you move the pan. If it's rock-hard, keep proofing. If it's collapsing, it's overproofed—bake it anyway; it won't puff much in the oven.
Can I proof croissants in the refrigerator overnight instead?
Yes. Cold proof for 8–14 hours in the fridge. They'll rise slowly. Pull them out and let them sit at room temperature for 20–30 minutes before egg wash and baking. Cold-proofed croissants often have better flavor and a sturdier structure.
Why are my croissants pale instead of golden?
Either your oven isn't hot enough, or they didn't bake long enough. Pale croissants are underbaked. Next time, verify your oven temperature with a thermometer and bake for the full 22 minutes. Egg wash helps, too.
Why are my croissants greasy or leaving a puddle?
The butter is leaking out, usually because the dough warmed too much during lamination or shaping, or because the seals weren't tight when you rolled them. There's no fix at the baking stage. Next time, keep everything cold and pinch the seams firmly.
Can I bake croissants at a lower temperature for longer?
No. Lower heat bakes the outside before the layers puff, and the butter has time to escape. Stick to 400°F and 18–22 minutes. Higher oven temps (425°F) work too but darken the outside faster, so watch closely.
Should I score the tops before baking?
No. Croissants don't need scoring. Scoring lets steam out and interrupts the lamination. They're designed to burst open on their own as the steam builds inside.
