A quick and easy casserole featuring seasoned ground beef, melted cheese, and a crunchy Doritos crust, perfect for family dinners and gatherings.

Ingredients

Scale
  • 1 lb ground beef (80/20)
  • 1 small onion, finely diced
  • 2 cloves garlic, minced
  • 1 packet (1 oz) taco seasoning mix or homemade blend
  • 1/2 cup water
  • 1 can (15 oz) black beans, drained and rinsed (optional)
  • 1 cup salsa
  • 1 cup shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • 2 cups crushed Nacho Cheese Doritos
  • 2 tbsp unsalted butter, melted
  • Optional toppings: sour cream or Greek yogurt, chopped fresh cilantro, diced avocado or guacamole, fresh lime wedges

Instructions

  1. Preheat oven to 375°F. Lightly grease a 10×10-inch baking dish with butter or nonstick spray.
  2. Heat a large skillet over medium-high heat. Cook ground beef and diced onion until beef is browned and onions are translucent, about 7–8 minutes. Drain excess fat if needed.
  3. Add minced garlic and cook for 30 seconds until fragrant. Stir in taco seasoning and 1/2 cup water. Simmer for 3–4 minutes until mixture thickens slightly.
  4. In a mixing bowl, combine cooked beef mixture, black beans (if using), and salsa. Spread evenly into prepared baking dish.
  5. Sprinkle shredded cheddar and Monterey Jack cheese evenly over the beef mixture.
  6. Crush Doritos finely, leaving some larger pieces for crunch. Mix crushed Doritos with melted butter until coated.
  7. Sprinkle Doritos mixture evenly over cheese layer, gently pressing down to help it stick.
  8. Bake for 20–25 minutes until cheese is bubbling and Doritos crust is golden brown and crispy.
  9. Let casserole rest for 5 minutes before serving to set layers and keep crust crunchy.

Notes

Let the casserole rest for 5 minutes after baking to keep the crust crunchy. If crust browns too quickly, tent with foil halfway through baking. Crush Doritos just before baking to maintain crispness. Adjust seasoning to taste before assembling. For dairy-free, substitute cheese and butter with plant-based alternatives.
