Instructions

  1. Melt 3 tablespoons butter in a saucepan over medium-low heat.

  2. Stir in 1/3 cup flour to form a roux; cook 2 to 3 minutes, stirring, to remove raw flour taste.

  3. Gradually whisk in 2 1/2 cups warm milk until fully incorporated and lump-free.

  4. Add a peeled 1/4 onion studded with 2 to 3 cloves and 1 bay leaf to the sauce; simmer 10 minutes, reducing by 20 percent.

  5. Remove bay leaf, onion, and cloves, then strain the sauce.

  6. Return strained sauce to the pan. Stir in 2 ounces each of grated Gruyère and Parmesan cheese until melted.

  7. Remove from heat, stir in 1 tablespoon butter, and adjust consistency with up to 1/2 cup milk if needed.
