Made with just 3 ingredients (butter, flour & milk), this ultra-creamy homemade béchamel sauce is the perfect base for mac & cheese and lasagna Bolognese. Ready in 20 minutes! Store in the fridge for up to 3 days or freeze. PS: this recipe makes about 1 quart of sauce which is perfect for a 5+ layer lasagna using 1/2 cup per layer.


The flavor of béchamel sauce, in its purest form, is mild and sweet. Feel free to season with extra salt, a pinch of nutmeg and/or Parmesan cheese. It really depends on what you’re using the béchamel sauce for. I typically leave mine plain and doctor it up as needed.


  • 80 g (6 tbsp) unsalted butter
  • 80 g (1/3 cup) all purpose flour
  • 800 ml (3 1/3 cups) whole milk
  • 1/4 tsp fine sea salt
  • Pinch of nutmeg (optional)


  1. In a large skillet (or high-sided braiser): melt the butter over low heat. Sprinkle the flour on top; mix well with a wooden spoon. Cook, stirring frequently, for 30 seconds to 1 minute to make a light roux. It will look like thick paste. Do not burn.
  2. Take the pan off the heat. Add 1/2 cup milk and whisk thoroughly to break up the lumps. Keep whisking until the mixture looks creamy. Slowly add the rest of the milk, whisking continuously as you pour. 
  3. Return the pan to the heat. Adjust to medium-low. Cook the sauce, whisking often, until it has thickened to the consistency of runny sour cream (it will thicken more as it cools). This should take about 12 minutes or more depending on the size of your pan. Season with salt to taste.
  4. When ready, the sauce should coat the back of a wooden spoon. Note: If not using the béchamel sauce right away, if will form a skin on the surface. See storage tips below.

Storage Tips:

Store the béchamel sauce in an airtight container, such as a quart container, with a splash of milk on the surface to prevent a skin from forming on top (alternatively, use plastic wrap or parchment paper to cover, pressed down directly onto the sauce). Chill for up to 3 days. Or freeze for 1 month. Defrost overnight in the fridge or at room temperature. Do not cook frozen sauce; it needs to thaw first.
