How to Make Doritos Casserole

  1. Heat Oven: Preheat the oven to 350°F.
  2. Cook Meat: In a large skillet, heat oil over medium heat. Add in the onions and cook for 5 minutes. Add in the garlic and the ground beef and cook until the meat is no longer pink, breaking up the clumps with a wooden spoon.
  3. Season & Add Salsa: Add in the taco seasoning, Ro-tel, and salsa. Cook for 5 minutes, stirring occasionally.
  4. Add Sour Cream: Stir in the sour cream evenly and then remove the mixture from the heat.
  5. Assemble Casserole: Pour half of the meat mixture into the bottom of a 9×13 pan. Top with 1/2-cup of the cheese and half of the Doritos. Repeat the process with the remaining ingredients, topping with the remaining 1/2-cup of the cheese.
  6. Cook: Cover the pan with foil and bake for 20 minutes. Then, remove the foil and bake for 10 more minutes.
  7. Serve: Garnish as desired and serve warm!

Tips for the Best Doritos Casserole

  • Don’t Crush Doritos Too Much: Make sure you don’t crush up your Doritos too finely. You want them in coarse chunks so they don’t soften inside the casserole.
  • Remove Foil After 20 Minutes: Once your casserole has cooked for 20 minutes, remove the foil and finish baking. This will help your cheese get nice and golden brown!
  • Use Lean Ground Beef: I recommend using 90% lean ground beef for this recipe.
  • Use Nacho Cheese Doritos: Any flavor of Doritos will taste great in this dish, but I have a soft spot for the nacho cheese ones. They’ll give you the cheesiest, most irresistible casserole ever!

Variation and Mix-In Ideas

As is the case with tacos, the ingredients you put in your Dorito casserole are entirely up to you. Here are some ideas for what to add to yours!

  • Add a Garnish: I love garnishing this casserole with diced tomatoes, avocado, cilantro, jalapeños or all of the above!
  • Mix up the Meat: This dinner is also delicious with turkey, chicken or a combination of chicken and ground beef.
  • Substitute Doritos: Don’t like Doritos? Use your choice of tortilla chips instead.
  • Add Veggies: Try topping this casserole with your favorite sautéd veggies.
