Preheat your oven to 350°F (175°C).

In a large skillet over medium heat, cook the ground beef thoroughly, about 5-7 minutes, and drain any excess grease.

In a mixing bowl, combine the cream of chicken soup and sour cream until smooth.

Grease a 9x13-inch baking dish. Layer half of the thawed hash browns, then the browned beef, creamy mixture, and a layer of cheddar cheese. Repeat the layers.

Bake for 40-45 minutes until bubbly and golden on top.

Let cool for 5-10 minutes before serving.
