Preheat your oven to 375 degrees.

In a large skillet, cook the ground beef over medium heat until it is browned.

Once the beef is browned, add in the corn, cream of mushroom soup, ½ cup of cheese, milk, sour cream, onion powder, black pepper, and crumbled bacon. Stir well to combine all the ingredients evenly.

In a 9x13 inch baking dish, layer the beef mixture evenly.

Sprinkle the remaining cheese on top, then arrange the tater tots in a single layer over the cheese.

Place the dish in the oven and bake uncovered for about 40-45 minutes.

After baking, sprinkle any remaining cheese on top and return the casserole to the oven for an additional 5 minutes.

Allow the dish to cool slightly before serving.
