How To Make Bechamel Sauce and Derivatives

What if I told you that one of the most essential French sauces is also one of the simplest to master? Enter béchamel, the velvety white sauce that forms the backbone of countless beloved dishes, from lasagna to creamy mac and cheese. It’s not just a sauce—it’s your ticket to elevating everyday meals into culinary classics.

In this post, we’ll break down the steps to making béchamel so you can perfect this versatile staple at home. Whether you’re a seasoned chef or a kitchen newbie, this guide will give you the confidence to conquer béchamel and even experiment with its delicious variations. Ready to stir up some magic? Let’s get cooking!

What is Bechamel?

Bechamel is a white sauce made with milk (sometimes cream) thickened with a roux. In French cooking, it is one of the five classic mother sauces. A mother sauce is a base out of which many other sauces can be made. We will talk about some of the sauces that can be made with bechamel shortly.

Don't let the fancy name fool you. It is not nearly as intimidating as it seems. As I said in the lasagna post, it is more than likely that you have made bechamel before and didn't know it.

How to make Bechamel

 

Bechamel Notes

First things first, let's talk about pepper. A lot of people like to use white pepper in their bechamel so they don't get the black specks you get with black pepper. I happen to hate white pepper. I find it smells and tastes like a horse barn. I also don't mind the black specks in my white sauce. I'll leave it up to you whether you use white or black pepper.

It is very easy for the roux to stick to the bottom of the pan and burn as the bechamel is simmering. There are a few ways to help prevent this.

Number one is to use a heavy bottom pot.

Number two is to stir the sauce regularly, making sure to scrape the bottom of the pot. If you scrape the bottom of the pot and notice brown or black bits floating in your bechamel, strain it right away and put it in a new pot. Taste it before you continue cooking because it may already taste burnt. In that case, you have to start over.

The third and probably safest option is to make the roux separately and add it after the milk has already been heated. In this case, you would simply cook the butter and flour together in a separate pot. The milk would be added to the softened onions and heated. At this point, the roux would be whisked in. You will still have to be vigilant in making sure the roux doesn't stick to the bottom of the pot, but this way is safer if that is your concern.

Derivative Sauces

From that basic bechamel recipe above, many other sauces can be made. Below, I am going to name the sauce and list what ingredients need to be added to make it. All the below additions are based on the above recipe. I should say that the sauces I'm about to list are very old school. You will likely only ever use one, maybe two of them.

Bohemienne

Adding a teaspoon or two of tarragon to the bechamel makes it a bohemian sauce. This sauce is traditionally served cold with cold fish or poached salmon.

Cardinal

The additions of truffles and lobster make a Cardinal sauce. How much lobster and truffles do you add? Until you can't add any more. This sauce is about decadence, not moderation. This sauce would typically be served over fish, lobster and truffles. That's right, lobster and truffles on lobster and truffles.

Ecossaise

Three or four whole eggs whisked into the bechamel make it an Ecossaise sauce. Unsurprisingly, this sauce is traditionally served over eggs.

Mornay

This is probably one of only two of these derivative sauces you will ever make. This is 1 cup of grated gruyere and ¼ cup of grated parm, whisked into the bechamel. At the last minute before serving 1-2 tablespoon of butter is whisked in as well. Traditionally, this sauce is served with fish, but it is also the base for mac and cheese. You can obviously add whatever cheeses you would like.

Alfredo

2-3 cloves of garlic sauteed with the onion, a ¼ cup of white wine reduced before the milk is added and then 1 cup of parmesan whisked in at the end. You likely already know what to do with alfredo sauce.

Conclusion

Mastering béchamel isn’t just about making a sauce—it’s about unlocking a world of culinary possibilities. Whether you're layering it into a lasagna, whisking it into a rich cheese sauce, or using it as the base for a soufflé, béchamel is your gateway to creating restaurant-worthy dishes at home.

Now that you’ve learned the techniques, it’s time to get creative. Experiment with adding herbs, spices, or even a splash of wine to make this classic sauce your own. The beauty of béchamel lies in its versatility and ability to elevate almost any dish.

So, grab your whisk, roll up your sleeves, and start cooking. With béchamel in your repertoire, the sky’s the limit for your culinary creations!
