Mornay Sauce

makes 1 quart


3 tbsp butter

½ cup all-purpose fl our

2 tsp vegetable oil

1/4 cup minced yellow onion

5 cups milk, warm

2 oz grated Gruyère cheese

2 oz grated Parmesan cheese

Salt, as needed

Ground white pepper, as needed


1. Melt the butter in a small saucepan over medium heat. Add the flour, stirring to combine, and cook until light brown to form a white roux, about 2 minutes. Remove from the heat and reserve.

2. In a saucepan over medium heat, heat the oil. Add the onion and cook, stirring frequently, until the onions are soft and translucent, about 6 minutes.

3. Add the roux and cook until the roux is very hot, about 2 minutes.

4. Gradually add the milk to the pan, stirring or whisking to work out any lumps. Bring the mixture to a full boil, then reduce the heat to low to establish a simmer. Simmer until the sauce has thickened and the starchy feel and taste of the flour have cooked away, about 30 minutes. Be sure to stir frequently and skim as necessary.

5. Season the sauce with salt, white pepper, and nutmeg, if using, and strain through a fine-mesh sieve.

6. Return the sauce to the pan and bring to a simmer over low heat. Add 2 oz each grated Gruyère and Parmesan. Finish up with 4 tbsp butter if desired, and adjust seasoning with salt and pepper.
