Preheat oven to 350 degrees. In a large skillet over medium-high heat, add the ground beef and onions. Cook until no pink is visible within the meat. Add the minced garlic and allow it to cook for 30-45 seconds then drain off any excess grease.

Season the meat with a packet of taco seasoning, add a can of Rotel and Mexicorn and stir until well combined.

In a 7x11 casserole dish, place a single layer of meat mixture in the bottom followed by a layer of cheese and a layer of crushed Doritos. Repeat this step once to complete the casserole.

Bake at 350 degrees for 15-20 minutes until the cheese is melted. Serve topped with fresh Pico De Gallo and sour cream. Enjoy!
