Set your oven to 350°F (175°C) to preheat. Grease a 9x13 baking dish using nonstick spray.

Smash your Doritos chips by hand or in a gallon-size bag. Keep two cups crushed fine and one cup in larger pieces for the topping.

Brown ground beef with the diced onion in a skillet on medium heat. When cooked, drain off any grease.
04 -
Once the beef looks cooked through, toss in the minced garlic and cook for about a minute. Stir in the taco seasoning, bag of corn, canned tomatoes, and your two cups of finely crushed Doritos. You can add black beans if you're using them.
05 -
Pull the skillet off the heat. Mix in the sour cream and stir in two cups of cheese until blended.

Move the mixed ingredients to the greased baking dish, smoothing it out evenly. Pop it in the oven for 5 minutes to warm through.

Take the dish out and sprinkle on one cup of the crushed Doritos (the bigger chunks) and the last cup of cheese. Bake again for another 5 minutes till the cheese melts.
08 -
Bring the dish out of the oven and serve right away. You can dress it up with sour cream, avocado, lettuce, green onions, and diced tomatoes if you want.
