Béchamel Sauce

A smooth, classic white sauce made by cooking a pale butter-and-flour roux with warm milk. Its gentle seasoning and velvety texture make it a dependable foundation for lasagna, gratins, croque monsieur, and baked vegetables.

Comment préparer

1
Melt the butter in a medium heavy saucepan over medium-low heat until fully liquid and foaming gently, without allowing it to brown.
2
Add the flour and whisk continuously for about 2 minutes, until a smooth, pale paste forms and the raw flour aroma disappears; keep the roux blond rather than golden.
3
Pour in the warm milk in a slow, steady stream while whisking constantly. Continue whisking until no lumps remain and the mixture is evenly fluid.
4
Bring the sauce to a gentle simmer over medium heat, whisking and scraping the corners of the pan. Cook for 6 to 8 minutes, until glossy and thick enough to coat the back of a spoon.

5
Remove the saucepan from the heat and whisk in the salt, white pepper, and nutmeg. Taste and adjust the salt while the sauce is hot.
6
Use immediately, or cool for 10 minutes with parchment or plastic wrap pressed directly onto the surface to prevent a skin from forming.

Pourquoi cette recette fonctionne

A pale roux thickens the milk without adding a toasted flavor, while gentle simmering hydrates the flour fully and produces a glossy, spoon-coating sauce.

Conservation et réchauffage

Comment la conserver

Cool the sauce promptly, press parchment or plastic wrap directly onto the surface, and refrigerate in an airtight container for up to 4 days.

Comment la réchauffer

Reheat gently in a saucepan over low heat, whisking often. Loosen with 1 to 2 tablespoons of milk at a time until smooth; do not allow it to boil vigorously.
