Ingredients

3 tablespoons butter
3 tablespoons flour
2 cups milk
1 cup shredded Gruyere cheese
salt and pepper to taste
optional: 1/2 teaspoon nutmeg

Instructions

In a saucepan over medium heat, melt butter. Stir in flour and cook for 1-2 minutes or until the mixture is smooth and bubbly while whisking.
Slowly whisk in milk, whisking until the mixture is smooth. Bring the mixture to a simmer, then cook for 2-3 minutes or until it has thickened.
Remove the sauce from the heat and stir in Gruyere cheese until it is melted and fully incorporated.
Season the sauce with salt, pepper, and nutmeg to taste. Serve immediately or store in a covered container in the refrigerator for up to 2 days. To reheat, cook over low heat in a small saucepan until warmed through.
