Easy Nacho Beef and Macaroni Recipe

Casseroles like this Mexican inspired nacho beef and macaroni are on our menu all year-round. I tend to gravitate to them most often on busy weekdays, when I can put them together ahead of time; then sprinkle the top with bread crumbs, cheese, or in this case, crushed Doritos just before baking. Easy ground beef recipes such as Beef and Noodles, Barbecue Beef and Tater Tot Casserole and Busy Day Lasagna always bring the family to the table in a hurry.

How to Make the Best Nacho Beef and Macaroni Recipe

  • Ingredients you’ll need to make homemade Nacho Beef and Macaroni: Elbow macaroni, ground beef, Rotel Chili Fixins tomatoes, diced onion, diced poblano or green bell pepper, red bell pepper, garlic, olive oil, garlic salt and lemon pepper (or black pepper), fiesta nacho cheese and cheddar cheese soup, milk, shredded colby jack cheese, one packet of taco seasoning, crushed nacho flavored Doritos, Mexican oregano and cilantro.
  • Kitchen tools you’ll need: A large deep skillet or Dutch oven, sharp knife and cutting board, cheese grater, 13 x 9 inch baking dish, measuring cups and spoons and a large spoon for mixing everything together.
  • The diced Rotel tomatoes used in this recipe are already seasoned for making chili. If you’re unable to find that particular kind, the seasonings will need to be adjusted to accommodate. For example, you may want to add additional cumin or chili powder depending on the brand of taco seasoning that you choose to use.
  • When beginning the preparation of this Nacho Beef and Macaroni casserole using a large pot, it can then double as the mixing bowl.
  • This entire casserole can be assembled several hours or one day in advance and chilled in the refrigerator. Allow it to sit on the counter for 15-20 minutes or so prior to baking to allow the ingredients to come to room temperature. You may also need to extend the bake time by a few minutes.
  • You can use an alternate flavor of shredded cheese or different flavor of Doritos for this dish.
  • Store baked Nacho Beef and Macaroni chilled in the refrigerator for up to 3 days. Reheat in single servings in the microwave.

Serving Suggestions for Nacho Beef and Macaroni

Casseroles stretch ingredients and if you’re feeding a crowd, this kicked-up beefy casserole will go a long way.

Top with your favorite nacho toppings such as a dollop of sour cream, black olives, pico de gallo or salsa. Any of your favorite taco toppings will work. It’s filled the with South-of- the-border flavors that always satisfy.

  1. If I use the package of taco seasoning….do I still add the cumin, chili powder and the rest of the ingredients?

    1. There’s no need to unless you’d like to adjust the heat. Add chili to your taste in that instance. Taste and make it to your preference.
