Preheat your oven to 350°F (175°C).

In a large skillet over medium heat, cook the ground beef until fully browned, about 8-10 minutes. Drain excess grease.

Stir in the cream of mushroom soup with the cooked ground beef and cook for an additional 2-3 minutes until heated through.

Spread the meat and mushroom mixture in a greased 9x13 baking dish and sprinkle shredded cheddar cheese on top.

Arrange a layer of frozen tater tots over the cheese layer, covering the entire surface.

Bake uncovered for 35-45 minutes until the tater tots are golden brown.

Remove from the oven, sprinkle any remaining cheese on top, and return to the oven for another 3-4 minutes until the cheese melts.

Let the casserole cool for a few minutes before serving hot.
