Ingredients

2 tablespoons unsalted butter
2 tablespoons all-purpose flour
1 cup milk warmed
¾ cup shredded Swiss cheese
1 teaspoon Dijon mustard
salt & pepper to taste

Instructions

In a small saucepan, melt butter over medium-low heat.
Whisk in the flour until smooth. Let bubble without browning, whisking frequently for 1 minute.
Gradually whisk in the warm milk, raise the heat to medium, and bring to a gentle boil, whisking frequently.
Reduce heat to medium-low and simmer, whisking frequently, until thickened, about 5 minutes.
Remove from heat and stir in cheese and mustard.
Season to taste with salt and pepper.
Transfer the sauce to a bowl and cover with a piece of plastic wrap pressed directly onto the surface of the sauce to prevent a skin from forming on the surface. Allow to cool.

Notes

Notes:

Be sure to refrigerate any leftover sauce in an airtight container within two hours of making it. It will keep in the fridge for up to 4 days.

You can also freeze it. It is best stored in a lidded mason jar. Make sure the sauce is completely cool, then fill the jar, leaving 1 inch at the top to allow for expansion. It will keep in the freezer for up to 6 months.

To reheat, remove the lid and heat in the microwave or on the stovetop. Stir frequently while reheating.
