This cheesy Doritos Casserole is made with ground beef, tomatoes, chiles, sour cream and much more! It’s a simple taco casserole recipe that’s full of savory goodness.


  • 2 tablespoons olive oil
  • 1 cup diced yellow onion, about 1 medium onion
  • 2 cloves garlic, minced
  • 1 pound lean ground beef
  • 1 package low- sodium taco seasoning
  • 1 (10- ounce) can Ro-tel tomatoes and chiles
  • 1/2 cup salsa
  • 1 cup sour cream
  • 1 1/2 cups grated cheddar cheese

  • Optional garnish – diced tomatoes, cilantro, jalapeños, avocado


  1. Preheat the oven to 350°F.

  3. Add in the taco seasoning, Ro-tel, and salsa. Cook for 5 minutes, stirring sometimes.
  4. Stir in the sour cream evenly and then remove the mixture from the heat.
  5. 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.
