Topping (if choosing to bake rather than make in a slow cooker)
Thaw potatoes and combine all ingredients in a large mixing bowl. Transfer mixed ingredients into a large slow cooker set to High temperature. Cook for approximately 3-4 hours, or until potatoes are tender and all ingredients are melted and hot.
Or for an oven baked version:
Preheat the oven to 350 degrees. Put mixed ingredients into a greased large casserole baking dish and sprinkle topping on. Bake for 1 to 1 ½ hours.
