Cowboy (Tater Tot) Casserole

Since Pinterest isn't letting me pin our favorite recipe I'll re-post it here! (original)

Cowboy Casserole
adapted from a recipe at Taste of Home
1 1/2 pounds ground beef (I used 80/20)
1 medium onion, chopped
3 cloves garlic, chopped
1 can (15.25oz) whole kernel corn, drained
1 can condensed cream of mushroom soup
2 cups cheddar cheese, shredded
1/2 cup milk
4 tablespoons sour cream
1 bag (30 oz) frozen tater tots (I used Ore-Ida Crispy Crowns)

In a large skillet cook the onion until tender and translucent. Add the chopped garlic and cook for 1 minute more. Add the beef and cook over medium heat until no longer pink. Drain the mixture and place into a large bowl and set aside.

In a small bowl combine the soup, milk and sour cream. Whisk until smooth. Add to hamburger mixture and stir to combine. Add corn and 1 cup of cheddar cheese. Gently mix to combine.

Grease a 9x13 inch baking dish. Layer half of the Crispy Crowns on the bottom, pour the hamburger mixture over the top and then layer with the other half of the Crispy Crowns. Sprinkle with remaining 1/2 cup cheese and bake at 350 for 25 - 30 minutes, or until golden brown and crunchy.
