How to Make Croissants at Home: Lamination Step by Step
Share
Croissants have a reputation for being the hardest thing in a home kitchen. They are not hard. They are slow, and they punish shortcuts. If you understand what lamination is actually doing and respect three numbers (butter temperature, dough temperature, and fold count), you can make real, honeycomb crumb croissants at home with a rolling pin. This is the process I teach, step by step, in the order you will do it.
What lamination is
Lamination means building alternating layers of dough and butter. In the oven, the water in the butter turns to steam, pushes the dough layers apart, and the fat fries each thin sheet of dough from both sides. That is where the shatter and the open, airy honeycomb come from. A classic croissant has 27 butter layers from three folds. More is not better. Too many folds and the layers merge into a brioche like crumb.
Step 1: Mix the détrempe
The détrempe is the base dough: flour, water, milk, sugar, salt, yeast, and a little butter. Mix it only until it comes together, not until it is smooth and elastic. An overdeveloped dough fights you during rolling and snaps back. Shape it into a rectangle, wrap it, and chill it for at least 1 hour or overnight. Overnight gives better flavor and a far easier roll.
Step 2: Prepare the butter block
Use a high fat butter, 82 percent or more. European style butters bend instead of cracking when cold. Pound and roll the butter between parchment into an even rectangle about half the size of your dough, then chill it until it is firm but still pliable. This is the most important temperature in the whole process: the butter and the dough need to be the same consistency, roughly 12 to 14°C (54 to 57°F). Cold enough to hold a layer, flexible enough to bend without breaking.
Step 3: Lock in the butter
Roll the détrempe to twice the length of the butter block, place the butter in the center, and fold the dough over it so the butter is fully enclosed with no gaps. Pinch the seams shut. Now you have one layer of butter inside two layers of dough.
Step 4: The folds
Roll the package into a long rectangle about 8 mm thick, keeping the edges straight and the corners square. Then fold. There are two folds you need to know:
- Letter fold (single fold). Fold in thirds like a letter. Triples the layers.
- Book fold (double fold). Fold both ends to the center, then fold in half. Quadruples the layers.
The classic croissant uses three letter folds. Between every fold, wrap the dough and rest it in the fridge for 30 to 45 minutes. The rest lets the gluten relax so the dough rolls instead of springing back, and it brings the butter back to the right temperature before it gets rolled thin again. If the butter ever starts to smear or feel greasy, stop and chill immediately. If it cracks into shards while rolling, it is too cold; let it sit 5 to 10 minutes.
Step 5: Final roll and cut
After the last rest, roll the dough to about 4 mm thick. Trim the edges so the layers are exposed, then cut long triangles with a base of about 9 to 10 cm. Clean cuts matter. A dull knife or a dragging pizza wheel seals the layers together and you lose the rise on that edge.
Step 6: Shape
Gently stretch each triangle a little longer, then roll from the base to the tip with light, even pressure. Do not stretch hard and do not roll tight. The tip should end up tucked underneath so it does not unroll in the oven.
Step 7: Proof
This is where most home croissants fail. Proof at 24 to 26°C (75 to 79°F), never warmer, for 2 to 3 hours until the croissants are visibly puffed, jiggle when the tray is tapped, and the layers have separated slightly. Any warmer and the butter melts out before baking, which gives you flat, greasy croissants sitting in a puddle. A turned off oven with a bowl of warm water works well as a proof box.
Step 8: Egg wash and bake
Brush with a beaten egg and a pinch of salt, avoiding the cut edges so the layers can open. Bake at 200°C (400°F) for about 18 to 22 minutes until deep golden brown. Pale croissants are undercooked inside. Let them cool at least 20 minutes before cutting so the interior sets.
The three numbers to remember
- Butter and dough at the same consistency, about 12 to 14°C.
- Three letter folds, 30 to 45 minute rest between each.
- Proof at 24 to 26°C until jiggly, then bake hot.

Frequently asked questions
Can I make croissants without a stand mixer?
Yes. The détrempe is mixed only until combined, which takes a couple of minutes by hand. Lamination is all rolling pin work.
Why did butter leak out during baking?
The proof was too warm or too long, or the layers were already smeared during rolling. Keep proofing under 26°C and chill the dough the moment the butter feels soft.
How many folds do croissants need?
Three letter folds for the classic 27 layer crumb. Some bakeries use one book fold plus one letter fold, which gives a similar count.
Can I freeze croissants?
Freeze them shaped and unproofed on a tray, then bag them. Proof from frozen, which takes an extra 1 to 2 hours, and bake as normal.
