Notes
Alternative Method - Instead of using the one-pot method with a Dutch oven, prepare the meat and potato mixture in a large soup pot. Pour the meat and potato mixture into a greased 9" x 13" casserole dish and sprinkle the remainder of the shredded cheddar cheese on top. Cover with tin foil and bake for 30 minutes, and carefully remove the tin foil. Bake for 15 more minutes.Ingredient Tips - The cubed frozen potatoes may be labeled "southern hash browns" in the frozen section. Servings Tips - This recipe serves 6 very hungry adults or at least 2 adults and 4 kids with leftovers. As a family of 5 (4 adult-sized portions and 1 kid portion), we typically have enough leftovers for 2 servings the next day.
