Ingredients Equipment Method Notes

Ingredients
  

  • 1 pound ground beef
  • 1 medium onion, chopped
  • 1 packet taco seasoning or 2 tablespoons
  • 2 cups shredded cheddar cheese, divided
  • 1 cup sour cream
  • 1 large bag 10 ounces
  • Optional: chopped green onions, black olives, salsa, guacamole for topping

Equipment

  • large skillet
  • Large bowl
  • 9x13-inch baking dish
  • spatula
  • Measuring cups
  • Measuring spoons
  • Oven

Method
 

  1. Preheat oven to 350°F (175°C). Grease a 9x13 inch baking dish.
  2. In a large skillet, brown the ground beef over medium heat. Drain off any excess grease. Add the chopped onion and cook until softened, about 5 minutes.
  3. Stir in the taco seasoning and cook for another minute.
  4. In a large bowl, combine the cream of mushroom soup, diced tomatoes with green chilies (undrained), 1 cup of the shredded cheddar cheese, and sour cream. Mix well.
  5. Add the cooked ground beef mixture to the bowl with the creamy sauce. Stir to combine.
  6. Spread the beef and cheese mixture into the prepared baking dish.
  7. Sprinkle the crushed Doritos evenly over the beef mixture.
  8. Top with the remaining 1 cup of shredded cheddar cheese.
  9. Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.
  10. Let the casserole cool for a few minutes before garnishing with your favorite toppings. Serve warm and enjoy!

Notes

For extra flavor and crunch, lightly toast the crushed Doritos in a dry skillet before adding them to the casserole. You can also assemble the casserole ahead of time and refrigerate it for up to 24 hours before baking. If the casserole is too dry, add a splash of milk or broth to the beef mixture before baking. To prevent the Doritos from burning, cover the casserole with foil during the last few minutes of baking. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave or larger portions in the oven at 350°F (175°C) until heated through.
