How to Make Béchamel Sauce
Step 1: Make the Roux
In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the flour.
Cook for about 1–2 minutes, whisking constantly, until the mixture is smooth and slightly golden. This removes the raw flour taste.
Step 2: Add the Milk
Slowly pour in the warm milk, whisking continuously to prevent lumps.
Step 3: Thicken the Sauce
Continue whisking as the sauce heats and thickens, about 3–5 minutes. It should coat the back of a spoon.
Step 4: Season
Add salt, pepper, and a pinch of nutmeg. Taste and adjust as needed.
Tips for Perfect Béchamel

- Whisk constantly for a silky smooth texture
- Don’t brown the roux too much—you want a pale sauce

FAQ: Béchamel Sauce
What is béchamel sauce made of?
Béchamel sauce is made from a simple combination of butter, flour, and milk, along with salt, pepper, and sometimes a pinch of nutmeg. It starts with a roux (butter + flour) that is whisked with milk to create a smooth, creamy sauce.
How do I keep béchamel sauce from getting lumpy?
The key is to whisk constantly and add warm milk slowly. This helps the sauce stay smooth and prevents clumps from forming. If lumps do appear, whisk vigorously or strain the sauce.
How thick should béchamel sauce be?
Béchamel should be thick enough to coat the back of a spoon. When you run your finger through it, the line should stay clean without the sauce running back together.
Can I make béchamel sauce ahead of time?
Yes, you can make it ahead and store it in the refrigerator for up to 3–4 days. Reheat gently on the stove and add a splash of milk to bring it back to a smooth consistency.
Can I turn béchamel into cheese sauce?
Absolutely. Simply stir in shredded cheese (like cheddar, gruyère, or parmesan) after the sauce has thickened to create a rich and creamy cheese sauce, also known as Mornay sauce.
Can I make béchamel without butter?
Traditional béchamel uses butter, but you can substitute with olive oil if needed. The flavor will be slightly different but still delicious.
Why does my béchamel taste like flour?
This usually means the roux wasn’t cooked long enough. Make sure to cook the butter and flour together for at least 1–2 minutes before adding milk to remove the raw flour taste.
