Quick answer

To make an easy cheese sauce, make a quick béchamel, take it off the heat, and stir in a cup of grated cheese until it melts smooth. Melting off the heat keeps it glossy instead of grainy. This is Mornay, the sauce behind macaroni cheese.

What it is

What is cheese sauce?

An easy cheese sauce is the most useful thing you can do with a béchamel. Make the white sauce, pull it off the heat, and melt grated cheese into the residual warmth. Classically this is called Mornay, and it is the difference between plain pasta and macaroni cheese, plain toast and a croque monsieur.

The reason to make it rather than buy it is texture. A real cheese sauce, melted gently, stays silky and pourable, while jarred versions are gluey by design. Once you can make a béchamel, a cheese sauce is sixty seconds away.

The recipe

What goes in cheese sauce?

1 cup
Béchamel
×
1 cup
Cheese

A cup of cheese to a cup of béchamel gives a rich, pourable sauce. More cheese makes it thicker and sharper; less makes it lighter. The single rule that matters is to add the cheese off the heat, because boiling cheese turns a smooth sauce grainy.

Method

How do you make cheese sauce?

  1. Melt the butter, whisk in the flour, and cook two minutes to a pale roux.
  2. Pour in the warm milk in a slow stream, whisking, and simmer until it thickens into a béchamel.
  3. Take the pan off the heat. Stir in the grated cheese a handful at a time until fully melted.
  4. Season with the mustard powder and salt. Loosen with a splash of milk if it is too thick.

Cook's notes

What should you know before making cheese sauce?

History

Where did cheese sauce come from?

Mornay, the cheese-enriched béchamel, sits in Auguste Escoffier's 1903 catalogue of sauces as a derivative of the white mother sauce. The home-kitchen cheese sauce that powers macaroni cheese is the same recipe under a plainer name.

Drawn from the public-domain text of Auguste Escoffier, Le Guide Culinaire (1903).

Derivatives

Welsh-style rarebit

Nacho sauce

FAQ

Common questions.

How do you make cheese sauce?

Make a béchamel from butter, flour, and milk, take it off the heat, and stir in grated cheese until smooth. Season with mustard powder and salt.

Why is my cheese sauce grainy?

The cheese was boiled. Always melt cheese into the sauce off the heat, and use cheese you grated yourself rather than pre-shredded.

What cheese is best for cheese sauce?

Sharp cheddar and Gruyère melt smoothly and taste strong. A blend works well. Avoid very low-moisture or pre-shredded cheeses, which melt poorly.

What is the difference between cheese sauce and Mornay?

They are essentially the same thing. Mornay is the classic French name for a béchamel finished with cheese; cheese sauce is the everyday name.

How long does cheese sauce keep?

Three days in the fridge. Reheat very gently with a splash of milk, since cheese sauces stiffen and can split if overheated.
