Step 1

Preheat oven to 350 degrees F. Coat a 2-quart baking dish with cooking spray.

Step 2

Heat olive oil in a large pan over medium heat. Add ground beef and season with salt and pepper to taste.

Step 3

Cook for 4-5 minutes, then add onion and cook for another 4 minutes or until the onion has softened and meat is cooked through. Add garlic and cook for an additional 30 seconds.

Step 4

Stir in taco seasoning, enchilada sauce, beans, and corn. Bring to a simmer and cook for 5 minutes.

Step 5

Pour beef mixture into prepared baking dish and spread into an even layer.

Step 6

Place corn muffin mix into a bowl. Add eggs and milk according to package directions. Mix until a batter forms, then add cheese and stir until just combined. Spread batter over the layer of meat.

Step 7

Bake for 40-45 minutes until topping is golden brown and a toothpick inserted into the cornbread layer comes out with just a few crumbs attached. (If your casserole is browning too quickly, you can cover it with foil for the duration of the bake time.)

Step 8

Cut into slices and serve with your choice of toppings!
