Preheat the oven to 350°F (175°C).

In a skillet, brown 1 pound of ground beef for 5-7 minutes.

Combine browned beef with 1 can of cream of mushroom soup, 0.5 cup of milk, 1 teaspoon of garlic powder, and 1 teaspoon of onion powder.

Layer the beef mixture in a greased baking dish, then add drained corn and shredded cheese.

Arrange frozen tater tots evenly over the cheese layer.

Bake for 30-35 minutes until tater tots are golden brown.

Let the casserole cool for about 5 minutes before serving.
