This Mac and Cheese Casserole is all you need for a comforting and tasty meal. It is creamy and smooth, with strong cheesy flavors that will melt in your mouth. The bacon topping is the perfect finish for this dish since it adds some crunchiness to it and some additional flavor. The casserole is also made with three types of cheese: cream cheese, mozzarella, and sharp cheddar cheese.

The homemade sauce is rich and creamy thanks to the mix of sour cream, heavy cream, and cheese. I used the classic roux based cheese sauce, where butter and flour are cooked together, and then the heavy cream and sour cream is added. As a result of this technique, you will have the creamiest and cheesiest casserole possible.

Due to mixing the ingredients together, and then adding pasta into it, the cheese proportionally and evenly integrates in this dish. Additionally, baking the casserole for 30 minutes after assembling it together, ensures you have a perfectly balanced and cheesy casserole. To make it even more amazing, I have added a buttery topping made of Ritz crackers!

Recipe Tips:

  • Before baking the casserole, make sure the pasta is not overcooked. Preferably, the pasta has to be al dente, since it will cook some additional time in the oven.
  • Similarly, you do not have to cover the casserole with foil when baking. This way, the topping will get golden brown and crunchier.
  • Additionally, use quality cheese. If you want a truly creamy texture, it is best not to use pre-shredded cheese. Take the extra few minutes and shred your own cheese.
  • You don’t need to rinse the cooked pasta for this recipe especially if you will be using pre-shredded cheese. This way the starch from the pasta will thicken the sauce.
  • Feel free to swap cheeses for a combination of whatever you have on hand. Such cheeses as Asiago, Gouda, smoked Cheddar, Monterrey, will work just as well.

Do I have to bake my Mac and Cheese Casserole?

For this recipe, I went ahead and baked the casserole. However, if you are short of time, you can actually eat it right from the pan or just stick it under the broiler for a few minutes to brown the top. This will work just as well and is a great shortcut when you are running low on time.

What is the best cheese to use for Mac and Cheese Casserole?

This totally depends on your taste and preference. Any good quality melting cheese will perfectly work for this dish. A combination of cheddar, mozzarella, and Parmesan is what I usually use. Similarly, a sharp white cheddar cheese, Monterrey, or Asiago will produce a smooth, rich and creamy sauce.


  • To freeze, transfer the mixture to a buttered 9-by-13-inch freezer-to-oven baking dish.
  • Cover tightly with aluminum foil and wrap in plastic wrap.
  • Freeze for up to 6 months.
  • Bake, frozen and covered with foil, at 350°F, for 1 hour.
