White sauce – Besciamella

One of the bases for many dishes in Italy. To remember the right amount of ingredients, in Italy we use the "rule of one" (regola dell'uno): 1 liter of milk, 100 grams of flour and 100 grams of butter. Don't worry, I translated it into cups! Read the recipe and my step by step guide for the best result!

Ingredients

  • 100 g (8 tbsp) unsalted butter
  • 100 g (2/3 cup) unbleached all-purpose flour
  • 1 liter (4 cups) whole milk, heated
  • A pinch of grated nutmeg
  • 1/2 teaspoon salt

Preparation

Heat the milk. Meanwhile, in a saucepan, melt the butter (and/or oil, see notes below!) over low heat. 

Remove the saucepan from the heat, add the flour to the melted butter and whisk with a wire whisk or a wooden spoon. This process will create what is called the “roux.” Cook it at low heat for 2-3 minutes, until smooth and with a nutty color (not brown!). 

Add the hot milk and whisk until the roux dissolves in the milk. Keep stirring the sauce while cooking at medium heat for 5-7 minutes, until the sauce thickens. 

Season with a pinch of nutmeg and salt to taste. 

Use immediately or transfer in a bowl and cover with a plastic wrap to avoid a skin from forming on the surface.

Tips & notes

  • The sauce thickens as it cools down. You can thin it by whisking in more milk.
  • Once cool, the besciamella can be stored in the fridge in an airtight container for a maximum of 2/3 days.
  • This is a lot of butter! But that’s what the original recipe asks for. If you want to make a lighter besciamella, use half the butter (4 tbsp) and 50 g (1/3 cup and 1 tbsp) of olive oil. You can also use just oil (100 g, 3/4 cup). Less butter, more oil! 😉
