A hearty Mexican Beef Casserole made with ground beef, black beans, tortilla chips, Rotel tomatoes, taco seasoning, and cheddar cheese, layered and baked until hot and bubbly.
Preheat the oven to 325°F (160°C). Lightly grease a 9x13-inch baking dish.
Cook the Beef
In a large skillet, brown the ground beef with the chopped onion over medium heat until fully cooked. Drain excess grease.
Prepare the Filling
Add the black beans, Rotel tomatoes, taco seasoning, cream of chicken soup, and water to the skillet. Stir until well combined. Simmer for 15 minutes to heat through and allow flavors to blend.
First Layer
Spread a layer of crushed tortilla chips on the bottom of the prepared baking dish. Spoon half of the beef mixture evenly over the chips.
Cheese Layer
Sprinkle half of the shredded cheddar cheese over the beef mixture.
Second Layer
Add another layer of crushed tortilla chips, followed by the remaining beef mixture. Top with the remaining cheese.
Bake
Cover the casserole with aluminum foil and bake for 25–30 minutes, until the cheese is melted and the casserole is bubbly. Remove from the oven and let rest for 5 minutes before serving.
Garnish and Serve
Serve hot with sour cream and salsa on the side.
