How Long Does It Take to Make Croissants from Scratch?

Quick Answer

Making croissants from scratch takes 18–22 hours from mixing the dough to pulling golden, flaky pastries from the oven. Most of that time is passive — chilling and proofing — with roughly 2–3 hours of active work spread across the process.

Detailed Timeline

Initial refrigeration	—	1–2 hours
Preparing the butter block	10–15 min	10–15 min
First fold (single turn)	10 min	10 min
Chilling between folds	—	30–60 min
Second fold (single turn)	10 min	10 min
Chilling between folds	—	30–60 min
Third fold (single turn)	10 min	10 min
Overnight refrigeration	—	8–12 hours
Shaping	20–30 min	20–30 min
Final proof	—	1.5–2 hours
Egg wash & baking	5 min prep	15–20 min

The Lamination Process

Lamination is what separates a true croissant from ordinary bread. You encase a cold block of butter inside the dough and perform a series of folds — typically three single (letter) folds or two double (book) folds. Each fold multiplies the number of butter-and-dough layers, creating the signature flaky structure.

The key to successful lamination is temperature control. The butter must remain cold and pliable — around 15°C (60°F) — so that it folds cleanly between dough layers rather than melting into them or shattering. This is why chilling between folds is non-negotiable.

Proofing Times

After shaping, croissants need a final proof at a controlled temperature of 24–27°C (75–80°F). Proofing too warm will melt the butter layers before baking, collapsing the lamination. Proofing too cold will take significantly longer and may produce a denser crumb.

A properly proofed croissant will be visibly puffed, jiggly when the tray is gently shaken, and the layers will be slightly visible at the edges. This stage typically takes 1.5–2 hours at room temperature.

Common Mistakes That Add Time

• Skipping rest periods: Rushing between folds results in elastic, shrinking dough that tears and requires additional chilling to relax.
• Warm kitchen: Working in a hot kitchen forces extra trips to the refrigerator.
• Under-proofing: Impatient bakers who cut the final proof short get dense, bready croissants rather than airy, layered ones.

Tips for Efficiency

Many bakers break the process across two days: mix and laminate on day one, then shape and bake on day two after an overnight cold retard. The overnight rest actually improves flavor development through slow fermentation, so this approach yields both convenience and better-tasting croissants.

Baking

Croissants bake at 200°C (400°F) for 15–18 minutes. They should be deeply golden — not pale — for the best flavor and texture. An egg wash applied just before baking gives them their characteristic glossy sheen.
