Classic Béchamel Sauce
Silky, creamy, and perfectly smooth, this French mother sauce is the foundation of countless dishes. Made with just butter, flour, and milk, it transforms into a velvety sauce seasoned with a hint of nutmeg. Use it in lasagnas, gratins, or as a base for cheese sauce.

- prep · ~2 min
Warm the milk.
Gently warm the milk in a separate saucepan or microwave until lukewarm. Do not boil; you just want to take the chill off so it blends smoothly into the roux.
TIPCold milk poured into a hot roux causes lumps. Always warm the milk first. - saute · ~3 min
Make the white roux.
Melt the butter in the saucepan over medium heat. Once it stops foaming, add the flour all at once. Whisk continuously and cook the paste until it turns a pale, sandy blonde color and smells slightly nutty, about 2 minutes. Do not let it brown.
TIPCooking the flour for a full 2 minutes removes the raw-flour taste. Stir constantly to avoid scorching. - simmer · ~5 min
Gradually whisk in the warm milk.
Pour the warm milk in slowly, about half a cup at a time, whisking vigorously after each addition. Make sure each increment is fully incorporated and the sauce is smooth before adding the next. Once all the milk is in, bring the sauce to a gentle simmer.
TIPThe sauce will thicken quickly at first and then loosen as you add more milk—trust the process and keep whisking. - simmer · ~7 min
Simmer until thick and velvety.
Reduce the heat to low. Let the sauce bubble gently, stirring frequently with the whisk to prevent a skin from forming on the bottom, until it coats the back of a spoon and has a silky, flowing consistency, about 5 to 7 minutes.
TIPFor a thicker sauce (like for croquettes or soufflés), simmer a minute longer. For a thinner sauce (like for soups), add a little extra milk. - mix · ~1 min
Season the sauce and serve.
Remove the pan from the heat. Whisk in the salt, a pinch of freshly ground black pepper, and the nutmeg. Taste and adjust seasoning if needed. Use immediately or cover the surface with plastic wrap to prevent a skin from forming.
TIPStraining the finished sauce through a fine-mesh sieve gives it a perfect silky restaurant texture.
