Brown 1 lb of ground beef in a large oven safe skillet over medium-high heat, add all seasonings, and the onion.
If you don't have an oven safe skillet you can brown the ground beef and then add all of the rest of the ingredients to a 9X13 baking dish instead!
Let that cook until beef is cooked through and onions have softened. Drain any grease from the skillet.
Add the minced garlic, Rotel, corn (drained) and stir well.
Next, add about ½ cup sour cream and 1 cup of shredded cheddar cheese.
Crush Nacho Doritos and add 1 ½ cups of crushed Doritos to the skillet. Stir everything together well.
Top the skillet with 1 cup of cheese and about 2 ½ cups of crushed Doritos.
Bake at 350 degrees F in the oven for 15-20 minutes.
