Instructions

1. Boil the macaroni for three minutes after the pasta is al dente, which means cooked but still firm. You want to macaroni to be soft. Place it in a casserole dish, then add the tomato sauce and grated cheese.

2. Distribute the butter in tablespoons throughout the dish to keep the macaroni moist. Cover the casserole dish with tinfoil or a tight-fitting lid.

3. Cook the casserole for 25 minutes at a high heat, approximately 375 degrees F, so the vapor doesn't have much of an opportunity to escape. This further ensures the moisture will stay inside because, even with a lid, some moisture will escape. Cooking on high, as opposed to low, limits the required cooking time, which limits the amount of moisture that evaporates from the dish.

4. Keep your mac and cheese warm but still moist by turning off the oven and leaving it inside covered. If you have it in for a period longer than 20 minutes, turn the heat to 180 degrees F and leave it in the oven for up to 30 minutes without it getting dry.
