What mac and cheese is made of

Mac and cheese is a dish that’s cooked either in the oven or stove using a combination of pasta, cheese, milk, heavy cream and/or butter. Variations of this dish often include a breadcrumb topping or ingredients like bacon or herbs stirred into coated pasta. No matter the preparation, mac and cheese is the quintessential dish to enjoy as a side or main meal.

The #1 secret to creamy reheated mac and cheese

As mac and cheese sits in the fridge, the cheese mixture sets — that turns this once-creamy dish solid. To make your mac and cheese velvety again, First for Women Food Editor Charles Grayauskie suggests combining it with a bit of milk. “Stir in about 2 Tbs. of milk per 1 cup of mac and cheese and reheat,” he says. The milk loosens up the pasta and helps create the creamy sauce as it’s reheating. Heavy cream works well in this case too and adds an extra touch of richness to the mac and cheese. After adding the dairy, you can begin reheating the pasta dish using your preferred method.

  1. Preheat the oven to 350°F.

  3. Cover the mac and cheese with aluminum foil.
  4. Bake until the mac and cheese is heated through, about 20 to 30 minutes.
  5. After 20 minutes, remove foil and cook for an additional 10 minutes until the cheese is starting to brown.
