This is a super easy recipe for a smooth and creamy Thermomix Béchamel Sauce. It's a versatile base for various dishes, including lasagne, moussaka, gratins, and fish pie.
Béchamel Sauce is simply butter and flour mixed together to make a roux. Then, milk and a pinch of nutmeg (if using) are added and heated until thickened. The key to success is continuously stirring the sauce so no lumps form.
What is a Roux?
A roux is a mixture of equal parts flour and fat cooked together until a light brown paste forms. When combined with milk and simmered until thickened, it creates a sauce.
Making it in the Thermomix saves time and effort. The machine's constant stirring and controlled heat ensure a creamy, lump-free sauce every time.
