Mexican Tater Tot Casserole is a hearty, comforting dish loaded with seasoned ground beef, cheese, and crispy tater tots. Tex-Mex flavors give this classic casserole a bold twist the whole family will enjoy.
In a large skillet, cook the ground beef and onion, breaking the meat up as it cooks, until no longer pink. Add the minced garlic and cook for an additional 1-2 minutes.
Drain any grease. Then stir the corn, black beans, enchilada sauce, Rotel and taco seasoning into the beef mixture, and simmer on low for 5 minutes.
Pour the mixture into a greased 9x13 inch casserole dish and spread evenly. Top with a single layer of tater tots.
Transfer the casserole dish to the oven and bake for 35 minutes.
Remove from the oven, top with cheese and bake for an additional 8-10 minutes, until the cheese is melted.
Top with diced tomatoes, black olives and green onions to serve.
