Spread hash browns evenly on the bottom of a greased 9x13 baking dish.

Mix chicken soup, sour cream, and melted butter together. It looks gross, but trust the process.

Spread mixture over the hash browns using a rubber spatula.

Top with cheese, then bacon, and finally the onions.

Bake covered at 350 for 45 minutes. Remove foil/cover for the last 5-10 minutes.
