In a large skillet over medium heat, cook ground beef until no longer pink, breaking it up as it cooks. Drain excess fat, leaving a small amount for flavor.

Add corn, cream of mushroom soup, 1/2 cup cheddar cheese, milk, sour cream, onion powder, black pepper, and crumbled bacon to the beef. Stir until fully combined and creamy.

Arrange tater tots in a single, even layer over the beef and cheese mixture without overlapping.

Bake uncovered in a preheated oven at 375°F (190°C) for 40 to 45 minutes, until tater tots are golden and casserole is bubbling at the edges.

Sprinkle any remaining cheese on top and bake for an additional 5 minutes until melted and bubbly. Let rest for several minutes before serving.
