Easy Taco Casserole Recipe with Ground Beef and Doritos (Print version)

A cheesy ground beef taco casserole layered with crushed Doritos, beans, salsa, and a crisp chip topping.

# Ingredients:

For the beef filling

01 - 1 tablespoon olive oil
02 - 1 lb (450 g) lean ground beef
03 - 1 small yellow onion, diced
04 - 2 cloves garlic, minced
05 - 1 packet (1 oz / 28 g) taco seasoning
06 - 1/3 cup (80 ml) water
07 - 1 can (15 oz / 425 g) black beans, drained and rinsed
08 - 1 cup (165 g) corn kernels, drained if canned
09 - 1 can (10 oz / 283 g) diced tomatoes with green chiles, drained
10 - 1 cup (240 g) chunky salsa
11 - 1/2 cup (120 g) sour cream

For layering and serving

12 - 5 cups (about 140 g) nacho cheese Doritos, lightly crushed, divided
13 - 2 cups (225 g) shredded Mexican cheese blend, divided
14 - 2 cups shredded lettuce, for serving
15 - 1 cup diced tomatoes, for serving
16 - 1 avocado, diced, for serving
17 - 1/4 cup chopped cilantro or green onions, for serving
18 - Lime wedges and extra sour cream, for serving

# Instructions:

01 - Heat the oven to 350 F. Lightly grease a 9x13-inch baking dish.
02 - Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and onion, then cook for 6-8 minutes, breaking up the beef, until browned and cooked through. Drain excess grease if needed.
03 - Add the garlic, taco seasoning, and water. Stir well and simmer for 2-3 minutes, until the seasoning coats the beef and the skillet looks saucy.
04 - Stir in the black beans, corn, diced tomatoes, and salsa. Cook for 2 minutes to warm through. Remove from the heat and stir in the sour cream and 1 cup of the shredded cheese.
05 - Spread 3 cups of crushed Doritos over the bottom of the prepared baking dish. Spoon the beef mixture evenly over the chips, then sprinkle with the remaining 1 cup cheese.
06 - Bake uncovered for 18-20 minutes, until the casserole is hot and the cheese is melted. Add the remaining 2 cups Doritos during the last 5 minutes for a lightly toasted topping, or add them after baking for maximum crunch.
07 - Let the casserole rest for 5 minutes. Serve with shredded lettuce, tomatoes, avocado, cilantro or green onions, lime wedges, and extra sour cream.

# Good to know:

01 - Best served hot, with fresh chips added at the end for crunch.
02 - Cook ground beef to 160 F for food safety.
03 - The filling can be made 1 day ahead and refrigerated before assembly.
