Preheat your oven to 350°F (175°C).

In a skillet over medium heat, brown the ground beef for 5-7 minutes, breaking it apart as it cooks, and drain any excess fat.

Add cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper to the skillet, stirring until well combined.

Grease a baking dish and spread the beef mixture evenly across the bottom. Layer the drained corn over the beef, then sprinkle the shredded cheese on top.

Arrange the frozen tater tots in a single layer over the cheese.

Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the tater tots are golden brown and crispy.

Allow the casserole to rest for a few minutes before serving.
