Ingredients

Scale
  • 1 pound lean ground beef
  • ½ yellow onion, diced
  • 1 teaspoon minced garlic
  • 1 packet taco seasoning
  • 12 oz bag frozen corn
  • 14.5 oz can petite diced tomatoes with green chilies (not drained)
  • 1 cup sour cream
  • 2 cups finely crushed Doritos
  • 1 cup loosely crushed Doritos (for topping)
  • 3 cups shredded Mexican blend cheese
  • 1 cup black beans (optional)
  • Sliced green onions, diced tomatoes, shredded lettuce, avocado, sour cream (optional, for garnish)

Instructions

  1. Preheat the oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
  2. Cook the beef: In a large skillet over medium heat, cook the ground beef and diced onion until the meat is browned and the onion is softened, about 5–7 minutes.
  3. Add garlic and seasoning: Stir in minced garlic and taco seasoning, cooking for another minute until fragrant.
  4. Add vegetables and sauce: Mix in the frozen corn, diced tomatoes with green chilies (do not drain), and black beans (if using). Simmer for 3–4 minutes to combine the flavors.
  5. Add sour cream: Remove from heat and stir in the sour cream until evenly combined and creamy.
  6. Layer the casserole: Spread a layer of finely crushed Doritos across the bottom of the baking dish. Pour the beef mixture evenly over the Doritos.
  7. Add cheese and top layer: Sprinkle 2 cups of the shredded cheese evenly over the beef mixture, then top with the loosely crushed Doritos and the remaining 1 cup of cheese.
  8. Bake: Place in the preheated oven and bake uncovered for 20–25 minutes, or until the cheese is melted and bubbly.
  9. Serve and garnish: Remove from the oven and let rest for 5 minutes before serving. Top with diced tomatoes, green onions, lettuce, avocado, or a dollop of sour cream for extra freshness.

Notes

Active time: ~20 minutes. Passive (baking) time: ~25 minutes. For an extra-crisp topping, broil the casserole for the last 2 minutes of baking.
