A velvety béchamel sauce is the secret to a great lasagne, but standing over a hot stove constantly whisking is nobody's idea of fun. This Thermomix method handles all the stirring for you, leaving you with a perfectly smooth white sauce every time.

Like a lot of people, béchamel was one of the first things I learned to make in cooking class at school - or home economics, as it was called back then. I still know how to make it the traditional way, but honestly, the Thermomix makes it so much easier.

Recipe Ingredients

Note: The full quantities are shown in the recipe card below.
- Butter - use unsalted butter to control the salt content.
- Plain flour - use plain flour, not self-raising flour, as the baking powder in self-raising flour will affect the texture of the sauce.
- Milk - use whole milk; lite milk will make the sauce watery.
- Nutmeg - optional; use sparingly, as it's a strong spice and can easily overpower the sauce.
Step-by-Step Directions
Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.

Storage
Store the béchamel sauce in an airtight container in the fridge for up to 5 days. Reheat gently on the stovetop, stirring frequently.
Freeze for up to 3 months in a freezer-safe container. Thaw in the fridge overnight. It may look slightly separated when reheated but will come back together.
