This easy bechamel sauce is one of those recipes I think is worth knowing how to make from scratch. It starts with a simple butter and flour roux, then warm milk is gradually whisked in until the sauce is smooth and creamy. I use it for everything from lasagna and pasta bakes to vegetables, and you can easily add cheese when you want a richer sauce. It takes about 20 minutes from start to finish, and once you know the basic technique, it’s an easy sauce to make again and again.
Why You’ll Love It
This easy béchamel sauce is smooth, creamy and surprisingly simple once you know the basic technique. It’s one of those versatile recipes I come back to for all kinds of savory dishes.
Ready in 20 minutes: You only need butter, flour, milk and seasonings for the basic sauce, and most of the cooking time is simply whisking and stirring.
So many ways to use it: I use béchamel most often in lasagna and pasta bakes, but it’s also great with vegetables or as the starting point for other sauces.
Easy to change up: One of my favorite variations is adding freshly grated cheese for a quick cheese sauce. You can also add nutmeg, fresh herbs or other seasonings depending on what you’re making.
Smooth and creamy: Warming the milk and adding it gradually to the roux is the trick I use to get a silky sauce without lumps.
You might also like to whip up some spicy mayo, jalapeno hot honey, fresh flavored garlic marinara sauce, or creamy tzatziki.
Homemade Béchamel Sauce Ingredients
A complete list of ingredients and amounts can be found in the recipe card below.
Unsalted butter: This combines with the flour to make the roux. I used European-style butter because I like its richer flavor, but regular unsalted butter works just as well.
Whole milk: Adds creaminess and body to the sauce.
All-purpose flour: Thickens the sauce when combined with butter.
Salt and black pepper: Season the sauce and balance the flavor.
Ground nutmeg: Optional. Adds a subtle warmth and complexity.
Fresh basil: An optional garnish for a hint of color and flavor.
Shredded white cheddar cheese: Another optional ingredient, cheddar makes it a cheese sauce. I used medium white cheddar. Shred your own, so it melts better.

Warm the milk: Heat milk gently in a small saucepan over a low heat or in the microwave until warm.
Make the roux: Melt butter in a saucepan, then add the flour and whisk constantly until lightly golden.
Add the milk: Turn it up to a medium heat, then slowly pour in a little hot milk slowly, a bit at a time, while whisking to create a smooth mixture.
Cook until thickened: Stir constantly until the sauce reaches your desired consistency.
Season the sauce: Add salt and pepper. Also add nutmeg if liked.
Add cheese (optional): Stir in shredded cheese using a wooden spoon until melted for a cheesy version.
Serve immediately: Remove from heat and use as desired.
Substitutions and Variations
Gluten-free option: Use a 1:1 gluten-free all-purpose flour blend in place of the regular flour. I’ve found a simple flour swap works well for thickening sauces like this, without needing to add anything else.
Use different milk: Swap whole milk for 2% or plant-based milk for a lighter version.
Add cheese: Parmesan, gruyère or mozzarella all work well in place of white cheddar.
Make it herby: Stir in chopped fresh herbs like thyme or parsley for extra flavor, or add a bay leaf.
Serving Suggestions
In pasta dishes: Use bechamel sauce in a chicken spaghetti casserole, pastitsio, lasagna al forno, or eggplant lasagna.
In soups: Use béchamel to add body and creaminess to soups like seafood chowder or chicken pot pie soup.
How to Store
Store: Let the creamy béchamel sauce cool completely and then refrigerate in an airtight container and use within 3 days. I like to put some plastic wrap on top of the sauce so it doesn’t develop a “skin”.
Freeze: You can freeze it in an airtight container for up to 2 months.
Thaw: Defrost it in the refrigerator overnight.
Reheat: You can warm bechamel back up in a pan on the stove, adding a splash of milk to loosen it up.
Top Tips
Warm the milk: Warm milk blends better and helps avoid lumps.
Stir constantly: Keep stirring while adding milk and while the sauce thickens. If you let it sit, the sauce can thicken at the bottom and burn.
Watch the roux: Don’t let the flour overcook or the sauce will taste bitter. Turn the heat down if it’s bubbling too much.
The right consistency: I look for the sauce to coat the back of a spoon without sliding straight off. If it gets too thick, I whisk in a little more milk. Keep in mind that it will thicken as it cools, and adding cheese will thicken it even more.
Use a whisk: This helps achieve a lump-free, silky texture.
Adjust seasoning at the end: Taste and tweak the salt and pepper before serving.
