You can make this dish as a casserole by placing the beef mixture in an 11″ x 13″ baking dish and spreading mashed potatoes over the top. Sprinkle cheese on top of potatoes and bake for 20 minutes at 350 degrees F. This works best when making this dish to take to someone’s house or sending food to a friend. Scoop the casserole onto a plate and finish with sour cream and bacon.
