  • Stir flour and 2 ½ tablespoons of milk together in a small, heavy-bottomed saucepan. Stir in the rest of the milk.
  • Bring it to a boil while stirring. Cook it over low heat for about 5 minutes while continuing to stir.
  • Add grated cheese and salt and let the cheese melt while stirring.
  • Taste the sauce to see if it needs more salt.

If the sauce appears too thick for your liking, whisk in some more milk – one tablespoon at a time – until it has the desired consistency. To avoid any lumps, make sure that both the milk and cheese are at room temperature before combining them. If you do end up with clumps, pour the mixture into a sieve to strain out clumps.


Refrigerate leftovers for later use and store the sauce covered in an airtight container until you would like to serve it. It is also a great way to save time and plan ahead if you are busy. When stored correctly, it will keep for 4-5 days in the fridge.
