- 8 ounces pasta (my favorites are the traditional elbow, gemelli, and bucatini)
- ¼ cup butter
- 3 tablespoons all-purpose flour
- ¼ teaspoon each kosher salt and freshly ground pepper
- 1 level teaspoon Dijon mustard (resist the urge to use a heaping spoonful…a little goes a long way)
- 2 cups milk (I use nonfat but 2% or whole are fine also.)
- 2 cups (8 ounces) shredded sharp cheddar cheese
