Microwave White Sauce for One Person

Microwave White Sauce For One Person

White sauce for one person is easy with this recipe that uses a mug to make a generous portion of white sauce for one person using the microwave.  You can halve this recipe if you simply want a small amount of white sauce to pour over a portion of fish or chicken, maybe adding in parsley or peppercorns if you wish.

If you’re making a single portion of sauce, a microwave is not only the easiest way to make sauce, but it makes the most sense as you’re dealing with a tiny amount, so a small microwave ramekin could be used to make this.

Pin It: Microwave White Sauce

The recipe below gives 150ml of sauce, but can be halved to make an even smaller quantity:


  • 25 grams butter or margarine
  • 15-20 grams flour
  • 100ml milk


  1. Using a small microwave safe jug, mug or small bowl, melt the butter or margarine in the microwave, this will take 15-30 seconds.
  2. Add the flour and use a fork to mix the butter and flour until they’re smooth.
  3. Slowly add the milk, mixing it through with the fork so it stays smooth.
  4. Microwave the sauce in 15-30 second blasts, mixing it with a fork each time to keep it lump free.  After about 2 minutes the sauce will be cooked and ready to serve

You control how thick the sauce is by adding the milk slowly as you go, until it’s the right thickness – as it cooks it will thicken up a little more, but you can keep adding a tiny splash of milk to loosen it up as you go!

You can add any flavours you wish to the sauce before pouring!

This is a great sauce that you can use however you wish, including:

  • Add cheese and you have a cheese sauce for cauliflower cheese
  • Add parsley to make a parsley sauce for one portion of fish
  • Use as a bechamel sauce for a lasagne for one person
  • Add to cauliflower and broccoli to make a cheese sauce for a cauliflower & broccoli bake
  • Use to make a cheese sauce for macaroni cheese.

Real White Sauce

This is a real white sauce recipe – it’s not a cutdown microwave version.  This sauce recipe simply uses regular ingredients and uses the microwave to bring them together easily – it is therefore OK to use this sauce in or on any dishes such as lasagnes, bakes, or as a pouring sauce.

The only “cheat” here is using the microwave instead of a saucepan on the hob!
