Classic béchamel is traditionally made with butter only.
For a lighter version, you can use 1 tablespoon butter + 1 tablespoon olive oil instead of 2 tablespoons butter.
Olive oil adds a softer flavor and a lighter feel while still keeping the sauce smooth.
Warm milk blends more easily and helps prevent lumps.
Whisk constantly while simmering for the creamiest texture.
For oven-baked pasta, use 3 tablespoons flour instead of 2 for a thicker sauce that clings to pasta and holds up in the oven. For a lighter option, you can use 2 tablespoons butter + 1 tablespoons olive oil instead of all butter.
For lasagna, double the recipe (4 cups milk total) and use 4 tablespoons butter + 4 tablespoons flour for a classic, silky béchamel that spreads easily and sets between layers. For a lighter option, you can use 2 tablespoons butter + 2 tablespoons olive oil + 4 tablespoons flour instead.
Make it yours
Add a pinch of nutmeg for a classic touch.
Stir in grated Parmesan or mozzarella for a quick cheese sauce.
For a lighter version, replace half (or all) of the butter with olive oil.
Swap a little milk for cream if you’d like it richer.
At the table
Use béchamel for lasagna, oven-baked pasta, vegetable casseroles, or spoon it over roasted cauliflower, broccoli, potatoes, or sautéed greens.
As a finishing sauce: Spoon warm béchamel over roasted cauliflower, broccoli, potatoes, or sautéed greens just before serving.
For baked dishes: Pour béchamel over cooked vegetables, optionally add cheese, then bake until bubbly and lightly golden for a gratin-style dish.
