I’ll show you how to make bechamel sauce and share tips on some common bechamel problems, such as avoiding lumps to get the perfect consistency every time.
Why This Recipe Works
- Child and beginner-friendly recipe with simple ingredients
- Suitable for lasagna, gratin, and pasta bake recipes
- Uses a classic flour-to-butter ratio for a stable roux

Ingredients You Will Need for Bechamel Sauce
Unsalted butter: Why unsalted? so that you can have control of the saltiness in the sauce.
Plain flour: Go for regular flour used for cookies and cakes; all-purpose flour works too.
Milk: Use full-fat milk

How to Make Bechamel Sauce
Melt the butter on low heat then toss in the flour and quickly stir/whisk to create what looks like a lump-free paste.

Pour in the milk as you whisk to combine. Add salt, nutmeg, and some black pepper to taste then let it thicken over low heat as you patiently stir.

It should be ready in about 6 minutes, or let it thicken until it gets to the consistency that you need for the recipe you are making.

Troubleshooting Common Bechamel Sauce Problems
Why is My Bechamel Sauce Lumpy?
Bechamel sauce will form lumps when milk is added too quickly or before the roux is mixed properly.
How Thick Should Bechamel Sauce be?
The ideal consistency depends on how you plan to use the sauce. A bechamel sauce for lasagna should be lighter than a bechamel sauce for potato gratin.
Make-Ahead, Storage, and Freezing Tips
How Can You Make Bechamel Sauce Ahead of Time?
Yes, bechamel sauce can be made up to 3 days ahead and stored in the fridge. This is quite helpful, particularly in recipes such as lasagna, other pasta baked dishes, or gratin, which can be frozen for busy weeknight meals.
How to Store Bechamel Sauce
To store unused bechamel sauce, cover it with cling film to avoid skin forming on top. If a skin does form, use a spoon or spatula to scoop it off.
Can You Freeze Bechamel Sauce?
You can freeze bechamel sauce, though it may separate slightly after thawing. To fix this, whisk while reheating it to restore the smooth consistency.
Recipes That Use Bechamel Sauce
Once you have mastered how to make this easy bechamel sauce, you can use it in a variety of comforting dishes such as:
Bechamel Sauce for Lasagna
Mouthwatering beef lasagna layered with fresh homemade sheets, a rich bolognese sauce, silky bechamel sauce, and mozzarella. A classic Italian ultimate comfort food, perfect for family dinners and make ahead meals.
