Ingredients

For the Base:
- 1 tablespoon olive oil
- 1 pound lean ground beef
- 1/2 medium onion, finely chopped
- 2 cups crushed Doritos (Nacho Cheese flavor)
Seasonings:
- 1 tablespoon chili powder
- 1/2 teaspoon garlic powder
- 1/2 teaspoon ground cumin
Filling:
- 1 (14 ounce) can black beans, drained & rinsed
- 1 (12 ounce) can corn, drained
- 1 (15.5 ounce) jar salsa
- 2 cups shredded Mexican cheese blend, divided
Optional Toppings:
- Diced tomatoes
- Fresh cilantro
- Sliced scallions
- Diced avocado
- Sliced black olives
- Sour cream
- Shredded lettuce

Steps

- Position rack in middle of oven and preheat to 350°F (175°C). This temperature ensures even cooking without burning the chips.
- Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add ground beef and cook for 5 minutes, breaking it into small, even pieces with a wooden spoon. The meat should be mostly browned with no pink spots remaining.
- Add onion and seasonings (chili powder, garlic powder, cumin). Cook for another 5 minutes until onions are translucent and beef is fully cooked. The mixture should be fragrant and well-combined.
- Create the base layer by evenly spreading crushed Doritos in a 9×13-inch casserole dish. Ensure coverage is uniform to prevent soggy spots.
- Drain excess fat from skillet if needed (leave about 1 tablespoon for flavor). Add beans, corn, salsa, and 1 cup of cheese. Stir until cheese melts and mixture is heated through, about 2-3 minutes.
- Layer the beef mixture evenly over the Doritos base. Top with remaining 1 cup cheese.
- Bake uncovered for 15-20 minutes until cheese is completely melted and edges are bubbling. Watch carefully after 15 minutes to prevent cheese from browning too much.
- Let rest for 5 minutes before serving. This allows the layers to set slightly for easier serving.
