  • Basic White Sauce

If you’ve ever read a vintage cookbook, you’ll know that homemade sauces were top on the list of basics to learn. While modern cookbooks may direct you to open this can, shake in this mix, stir and be done with it, the old ways are some of the best.

After years of buying canned cream soups to make Cheesy Potatoes, I realized that those cans were just a basic white sauce, something so simple and delicious that you can make in minutes—without all the preservatives and junk.

The secret to great tasting casseroles, sandwiches, pasta dishes, and chicken recipes? The secret is in the sauce— the white sauce, that is.

Why Make This

It’s simple. With only five basic ingredients: butter, flour, milk, salt, and pepper, you can pull together a great white sauce quite simply. It’s great to make when you have a lot of milk to use up.

It’s a versatile technique to learn. Once you master making a white sauce by prepping a roux and adding liquid, you’ll be set for making similar sauces, like Red Enchilada Sauce, 5-Minute Easy Gravy, and Easy Homemade Cream of Chicken Soup for Cooking.

It tastes amazing. Prepping a bechamel for your recipes ups the flavor level to eleven. It’s totally worth your while.

ingredients measured out to make a homemade white sauce.


This recipe is simple really and made of five basic ingredients:

  • butter
  • flour
  • milk (or broth)
  • salt
  • pepper – some folks recommend using white pepper so that the sauce is perfectly one tone.

To make this sauce is to conquer a really simple culinary technique that has all kinds of potential. You can flavor it any way you like (parmesan, spices, herbs, cheese, sauteed vegetables, chicken broth for some of the milk) to recreate any creamy sauce you desire.


Here are a few white sauce variations:

  • Fresh herbs, finely chopped like parsley, basil, or thyme
  • Grated cheese, like parmesan, asiago, or cheddar (technically, this will then be a Mornay sauce)
  • White wine or sherry for some of the milk
  • Chicken or vegetable broth for some of the milk
  • Sautéed mushrooms or celery
  • Caramelized onions
  • adding flour to melted butter in a saucepan.
  • whisking in the milk to the roux in saucepan.
  • adding more milk and simmering until sauce is thickened.
  • seasoning the bechamel with salt and pepper.

Step-by-Step Instructions

The process for making a homemade bechamel is super simple.

  1. Melt the butter in a medium saucepan over medium heat. Add the flour and whisk until bubbly and fragrant. This is called a roux. Combining the fat and flour first helps the flour to absorb liquid. Otherwise, your sauce can be lumpy if you just mix flour and liquid together.
  2. Slowly add some of the milk. It will froth and bubble and look a bit lumpy. That’s okay. It’s the flour and fat absorbing the liquid. Whisk until smooth.
  3. Add in the rest of the milk and whisk until smooth and creamy. Simmer until the sauce reaches your desired thickness.
  4. Remove the sauce from the heat and season it to taste with salt and pepper.

Use the sauce immediately in your recipe or store it in an airtight container in the fridge.

Freezing Instructions

Making a large batch of white sauce and freezing it in 2 cup portions is a great way to buy yourself some time in the future.

To freeze white sauce, place it in a freezer-safe container. Chill completely in the refrigerator before storing in the freezer, for up to 2 months.

Serving Suggestions

White sauce is delicious as a simple sauce for chicken and other cooked meats as well as for fish and noodles, but it’s also a great component for other recipes. That’s really all that canned “cream of” soup is—a white sauce enhanced with chicken broth, chopped celery, sautéed mushrooms, or whatever other flavor you want to “cream”.

One batch of this sauce, seasoned with salt and pepper and any of the variations listed can replace a can of creamed soup in your recipes. Yay for homemade!

Use this white sauce as a base for Chicken and Biscuit Pizza or the Bechamel layer in a Croque Monsieur sandwich. (Bechamel is the French name for white sauce.)

It can be the gravy in Chicken Pot Pie or a replacement for the ricotta layer in Lasagna. Stir in a few handfuls of shredded cheeses and you’ve got a delicious sauce for Alfredo Mac and Cheese or Stovetop Mac and Cheese.


Recipe Costs

Knowing how much it costs you to prepare a recipe can help you decide if it’s the type of recipe to make regularly or one you might want to save for special occasions. Let’s crunch some numbers and see how this recipe pencils out.

  • butter $0.40
  • flour $0.04
  • milk $0.34
  • salt and pepper $0.01

A 16-ounce batch of homemade bechamel costs just $0.79! Conversely, a 10-ounce can of commercial white sauce (with very dubious ingredients) costs $2.99. “Cream of” soups typically start at $0.99 for 10 ounces.

Clearly homemade is cheaper, and you can bet that it’s tastier, too!
