Tater Tot Casserole

We've tried several, and here is my favorite tater tot casserole. I got the recipe from my friend's blog and added the ground beef. Simple. Easy. Tasty.

INGREDIENTS:
1lb ground beef
1 (32-ounce) package frozen tater tots
1 (16-ounce) container sour cream
1 cup shredded cheddar cheese
1 (10.5 ounce) can condensed cream of mushroom soup
1 (6-ounce) can french fried onions

DIRECTIONS:
Preheat oven to 350 degrees. Grease a 9 x 13 inch baking dish. Cook, drain, and rinse the ground beef, set aside. Arrange tater tots in the prepared baking dish and spread ground beef over top. In a mixing bowl, combine sour cream, cheese, and mushroom soup. Pour this mixture over the tater tots. Bake for 30-45 minutes. Sprinkle onions over the top of the casserole and bake for an additional 15 min.
