Recipe information

  • Yield

    Makes about 2 cups

Ingredients

2 cups whole milk, or more, if needed
2 tablespoons unsalted butter
1 small Spanish onion, finely chopped
2 tablespoons all-purpose flour
1/4 teaspoon kosher salt
Pinch of cayenne pepper
4 ounces crumbled blue cheese (about 1 cup), plus extra for garnish
2 tablespoons finely chopped fresh chives

Preparation

  1. Step 1

    Pour the milk into a small saucepan and bring to a simmer over low heat.

    Step 2

    Heat the butter in a medium saucepan over medium heat. Add the onion and cook until soft, about 5 minutes. Stir in the flour and cook for 1 minute. Slowly whisk in the warm milk and continue whisking until the mixture thickens, about 2 minutes. Season with the salt and cayenne pepper and continue cooking, whisking occasionally, for 5 minutes.

    Step 3

    Remove from the heat and stir in the cheese. If the sauce is too thick, thin with a little extra milk. The sauce can be prepared 1 day in advance, covered, and refrigerated. Reheat gently in a double boiler. Sprinkle with the chives.
