Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with cooking spray or butter.

In a large skillet over medium heat, add the ground beef and cook for 5-7 minutes, breaking it up until it’s browned. Drain excess fat.

Stir in the cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper into the cooked beef. Mix thoroughly for about 2 minutes.

Pour the beef mixture into the greased baking dish. Layer the drained corn on top, followed by shredded cheese.

Arrange frozen tater tots evenly over the casserole, covering the entire surface.

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

Let the casserole cool for about 5 minutes before serving.
