If you made a pot roast yesterday and have lots of brown gravy left over, this easy casserole is a great way to utilize it for tonight. If you don't have brown gravy made and ready to go, make your own from the ground beef drippings.
Swiss Potato Beef Bake
1 lb ground beef
2 cups brown gravy
1 32 oz bag Potatoes O'Brien or Southern Style Hash Browns, defrosted
1/2 cup shredded Swiss cheese
Brown ground beef, season to taste with salt and pepper and drain. Add potatoes to a 13x9 baking dish and spread out evenly. Spoon ground beef over potatoes and pour gravy over entire dish. Bake at 350 degrees for 25 minutes, add Swiss cheese and continue baking an additional 10 minutes or until cheese is golden brown and bubbly.
