Béchamel sauce is a classic French white sauce with a rich, creamy texture. It's one of the essential "mother sauces" forming the base for many other delicious sauces and is incredibly easy to make.
In a saucepan over medium heat, melt the butter and whisk in the flour. Cook and whisk until the flour turns a light golden brown and has a nutty aroma, approximately 3-4 minutes
Whisk in the milk and turn the heat to low. Continue to simmer, whisking occasionally, until the sauce is smooth and slightly thickened, approximately 10-20 minutes.
Season with salt and nutmeg.
