This hearty, cheesy casserole layers seasoned beef, beans, veggies, and crunchy Doritos for a fun and flavorful Tex-Mex dinner. Perfect for a family meal or game day gathering.
Preheat oven to 350°F and grease a 9x13-inch baking dish.
In a large skillet over medium heat, cook ground beef until browned, breaking it apart as it cooks. Drain grease.
Add diced red pepper and onion to the skillet with the beef. Cook for 3–4 minutes until softened.
Stir in taco seasoning and water or broth. Reduce heat to low and let simmer for 5–6 minutes until thickened.
Add drained tomatoes and green chiles, black beans, and sour cream. Stir to combine and remove from heat.
Slightly crush about 1 cup of Doritos and spread them in the bottom of the prepared baking dish.
Layer half the beef mixture over the Doritos, then top with another layer of crushed chips and half the cheese.
Add the remaining beef mixture, top with more crushed Doritos and the remaining cheese.
Bake for 25–30 minutes or until bubbling and golden brown on top.
Serve hot, topped with sour cream, salsa, hot sauce, or chopped green onions, if desired.
Notes
Try substituting regular nacho cheese Doritos for a more classic flavor, or use spicy varieties for extra kick. This casserole also reheats well the next day.
