Don’t reheat more than you are going to use, as the more times you reheat it, the less appetizing your macaroni and cheese will become.
You may also substitute half and half or cream for a richer texture and flavor.
If you do not feel comfortable using plastic wrap in the microwave, you can also put an inverted plate over the dish, but be sure to use an oven mitt when removing it, as the plate can become hot. It will also release hot steam that can burn you.
If your microwave does not have a turning carousel, heat your macaroni and cheese in 45 second intervals, and turn the bowl in between.
For a bit of extra crunch, you could stir in 2-3 tablespoons of seasoned bread crumbs to the shredded cheese before sprinkling it on top.
If you do not have a double boiler, it is easy to make one. Find a metal or glass (preferably pyrex) mixing bowl that fits on top of your favorite saucepan. Add water to the pan, but not so much that it touches the bottom of the bowl. Add your food to the bowl, and place the pan with the bowl on top on the burner over medium heat.

Adding a half a tablespoon of butter to the macaroni and cheese will improve the taste and texture even more. You may also substitute half and half, or even cream for the milk for a richer texture.
Be patient and try not to overheat your macaroni and cheese, or you run the risk of it separating and becoming oily. If the macaroni looks dry as it heats, stir in some additional milk, one tablespoon at a time.
