What Is Bechamel?

A bechamel sauce is one of the five mother sauces of French cuisine. You start by making a roux, whisking butter and flour together over heat, then the milk or cream is slowly whisked in. The mixture thickens as it’s stirred and soon becomes thick enough for things like creamy gravy or a Lasagna with White Sauce.

Gradually whisk in milk. Slowly bring to a boil while stirring constantly, about one to two minutes. Reduce to simmer and allow to continue to thicken for five more minutes. Use this sauce immediately to make bechamel lasagna!

Tips for Making Bechamel Sauce

  • For best results, use your bechamel sauce right away. If you do have to hold it, store it in the fridge for up to three days. To reheat, warm on low and stir constantly as it loosens.

  • The trickiest part of making sauces is that they can break, which means they separate and curdle, looking rather unappetizing. But have no fear, follow these tricks and you can fix a broken sauce like a pro!

  • My personal preference is to use whole milk, because I like the creamiest option available. However, if you don’t have whole milk on hand, stick with the recipe and make a bechamel from 2%. For a lower-fat sauce, try non-fat milk.

  • You can easily double or triple this recipe if needed.
