If you’ve ever wondered how to make bechamel sauce, you’re in the right kitchen. This is the simple white sauce that turns weeknight pasta glossy, anchors lasagna, and simply lifts dishes with umami goodness.

What is Bechamel Sauce?

So what is bechamel sauce? Bechamel, or béchamel, sauce is the classic “white sauce” you make by whisking warm milk into a blond roux. It’s one of the mother sauces of French cuisine!

Béchamel, pronounced bay-shuh-mel, comes from a French businessman from the 17th-century – Louis de Béchamel. He isn’t the inventor of the sauce, but it was named after him!

Key Elements Of This Recipe

  • Unsalted Butter: Butter has such rich flavor and aroma when cooked. It’s the key fat that goes into our blond roux today.
  • Whole Milk: Warm milk is a key ingredient on how to make a bechamel sauce. This is what turns a blond roux into a bechamel sauce.

The Equipment Needed

How to Make Bechamel Sauce

In a small saucepan and gently heat the milk until steaming. Keep warm.

Pro Tip: If you want to go the fancy route, check out our fancy Bechamel Sauce Recipe and learn how to create an onion pique.

Make the Roux

Melt butter over medium heat in a medium saucepan.

Once the butter has melted, whisk in flour – a little at a time. Whisking constantly, cook the mixture for about 3-4 minutes until lightly blond. You’ve created a roux!

Putting It All Together

Whisk in the warmed milk to the roux. Be sure to add milk to the roux in 3-4 additions, whisking it into the roux before the next.

Once all the milk is in, continue to cook the mixture – bringing it to a gentle bubble, whisking constantly. Then, reduce the heat to simmer the mixture for 3-5 minutes until glossy. The sauce is done when it coats the back of a spoon.

Whisk in salt and white pepper to taste.

Pro Tip: Add a whisper of ground nutmeg for added fanciness!

That’s it! Such a simple sauce that adds so much depth and umami to your dishes!

Tips for the Best Bechamel Sauce

Here are some tips I’ve learned while experimenting with how to make the perfect bechamel sauce.

  • To avoid lumps, use warm milk and warm roux. This is crucial!
  • But, if you somehow end up with a lumpy bechamel, simply use a fine sieve to get the lumps out.
  • You can go fancy with bechamel sauce too – check out our Bechamel Sauce Recipe on how. I highlight recommend it because it adds tenfold the umami with just a tad more effort.

How to Store Bechamel Sauce

Yes, you can store bechamel sauce! Just press parchment paper or wax paper directly onto the surface of the sauce and refrigerate (up to 4 days).

To rewarm, place back in saucepan and add a splash of milk, whisking to restore the silky consistency. Keep in mind that freezing bechamel is not ideal. If you end up freezing, add a bit more milk to get the consistency back.
