Featured Ingredients
The glory of this thick and creamy sauce is that you only need basic ingredients.
- Butter: we’re using butter as the fat in this bechamel sauce. But, you can also use a different fat such as olive oil.
- Flour: we’re sticking with all-purpose flour for this classic bechamel sauce recipe, but we’ve used other glutenous flours such as white whole wheat.
- Whole milk: milk is used to create this thick and creamy sauce. We’re using whole milk, but other fats will work too.

How to Make Bechamel Sauce
Melt Butter
Melt butter over medium heat in a large saucepan.
Add Flour
Once the flour has melted, add the flour and whisk until the roux forms. It should be a thick paste and take 1-2 minutes.
Slowly Add MilK
Slowly pour the whole milk into the roux, constantly whisking. Within a few minutes, the bechamel sauce should become thick and creamy.
Remove from Heat
From here, you can either turn this yummy sauce into a bechamel cheese sauce by removing it from the heat and adding cheese or use this as a plain white sauce in something like lasagna.
