This basic white sauce can be used in a variety of dishes from lasagne to cauliflower bake. Just add seasoning as desired to suit the dish.
Melt the butter in a small saucepan over a low heat.
Whisk the flour into the melted butter.
Add the salt and pepper and mix well.
Cook over low heat, stirring for a full 2 minutes to minimise the taste of the flour.
(if your mixture is thickening slowly, continue cooking in 30 second intervals until thick and bubbly).
Turn up the heat slightly, then slowly add the milk, stirring constantly.
Bring to a low simmer and continue cooking slowly until the white sauce is smooth and thickened, about 10 minutes.
To change the thickness of a white sauce, simply use more or less butter and flour (keeping them equal) while using the same amount of milk.
Light stock, cream, or a combination may be used in place of the milk.
White sauce is typically best when made right before it's needed. However, it can be stored in the refrigerator for up to 3 days in a sealed container. Heat it up gently before use and stir in 1 tablespoon at a time of milk or cream if it's too thick.
It can also be frozen in a sealed container for up to 6 months.
