Béchamel is one of the mother sauces in classic French cooking, and one of the most important sauces to learn for all sorts of dishes, French and otherwise. It's a key ingredient in soufflé, a classic Bolognese lasagna, and even old-school mac and cheese. And it's incredibly easy to make. Here's how.

Why It Works

  • Cooking the flour and butter together first helps remove the flour's raw flavor, and prevents lumps from forming later.
  • A ratio of 1 1/2 tablespoons each of flour and butter per cup of milk makes a thickened yet still pourable sauce, great for all sorts of recipes.
  • Yield:Makes about 1 cup
  • Active time: 5 minutes
  • Total time:5 minutes


  • 1 1/2 tablespoons unsalted butter (3/4 ounce; 20g) (see note)
  • 1 1/2 tablespoons (12g) all-purpose flour (see note)
  • 1 cup (240ml) whole milk
  • Kosher salt and freshly ground black pepper
  • Freshly grated nutmeg, to taste (optional)


  1. 1.

    In a small saucepan, melt butter over medium-high heat (do not allow it to brown). Add flour and whisk to form a paste. Continue to cook, stirring, until raw flour scent is gone, about 1 minute. Whisking constantly, add milk in a thin, steady stream, or in increments of a couple of tablespoons at a time, whisking thoroughly and getting into all corners of the pan to maintain a homogeneous texture. Sauce will initially become very thick, then get very thin once all the milk is added.

  2. 2.

    Heat, stirring, until sauce comes to a simmer and begins to thicken slightly. Reduce heat to low and cook, stirring, until sauce is thick enough to coat the back of a wooden spoon, about 3 minutes.

  3. 3.

    Season with salt and pepper. Add nutmeg to taste, if using. If any lumps form, simply whisk thoroughly to remove them and smooth out sauce, or use a hand blender or countertop blender if lumps are particularly large or tough. Use sauce right away, or press a piece of plastic wrap over surface of sauce to prevent a skin from forming and keep warm until ready to use. Sauce can be cooled and stored in a sealed container in the refrigerator for several days. Reheat very gently on the stovetop or in a microwave to use.
