What You Need

A classic Thermomix white sauce is made using just a few basic ingredients.

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

The ingredients for a traditional white sauce.

Butter - you can use salted or unsalted butter for this recipe. If using salted butter, reduce the amount (or omit) the extra salt
Flour - use regular plain (all-purpose flour). When cooked with the butter, this roux thickens the sauce.
Milk - it's important to use full cream (full fat) milk (not skim or light milk) in Thermomix bechamel sauce. Skim milk will result in a thinner sauce.
Salt & Pepper - season to taste.
Ground Nutmeg (optional) - this is a classic ingredient in a bechamel sauce. It has a strong flavour so you only need a small amount. You can omit the nutmeg if preferred.
*Cheese (for my Thermomix cheese sauce variation) - adding grated cheddar cheese to your bechamel sauce turns it into a delicious Thermomix cheese sauce! See my instructions below for making this cheesy variation.

Equipment Needed

Unlike a traditional bechamel sauce where you need to use multiple pieces of equipment... making white sauce in the Thermomix couldn't be any more fuss-free - and all you need is a Thermomix!

Thermomix - you can use any of the Thermomix models for this recipe (TM31, TM5 or TM6). This machine will melt the butter, cook the roux and then thicken the sauce all in the one bowl!

Step 1 - Melt The Butter

Place the chopped butter into the Thermomix bowl.

Melt for 2 minutes or until smooth (and completely melted).

FAQs

Are bechamel sauce and alfredo sauce the same thing?

No. Bechamel is a simple sauce made using butter, flour, milk, salt and pepper. An alfredo sauce is made using cream, cheese (parmesan or cream cheese), butter, garlic and parsley.

Can I make this white sauce recipe using any model of a Thermomix?

Yes - this recipe is suitable for use in the TM31, TM5 and TM6 Thermomix models.

What is a roux?

A roux is made using equal parts butter and flour. The roux acts as the thickening agent in the bechamel sauce.

Can this bechamel sauce be used in lasagne?

Yes! My Thermomix bechamel sauce recipe is perfect for the creamy layer of lasagne. You can also use my cheese bechamel sauce variation (see above) if you prefer.

Can I use light or skim milk?

I don't recommend using light or skim milk in bechamel sauce as it doesn't thicken as well. Full cream milk is the best option when making a white sauce.

Expert Tips

Follow my simple tips for the perfect bechamel sauce!

Use the Thermomix bechamel immediately - it's best to use bechamel sauce immediately as it thickens further upon cooling.
Avoid the white sauce getting a 'skin' on top - if you're not using the white sauce immediately, place it into a container and then lay cling-wrap or plastic wrap directly on top of the sauce. This will stop a 'skin' forming on the top.
Store - in a container in the fridge for up to 1 week (with plastic wrap over the top - see previous tip).
Freeze - allow the sauce to cool before placing into ziplock sealable bags or an airtight container. Freeze for up to 3 months, then allow to defrost in the fridge before using.
