How to Reheat Mac and Cheese

Mac and cheese loses its creamy texture overnight because the cheese sauce solidifies and the pasta absorbs remaining moisture. Stovetop reheat with a splash of milk over medium-low heat and stir constantly. The microwave works but creates a dry top layer while the bottom stays cold. Add a slice of American cheese while reheating to restore the emulsified sauce texture.
