"My Aunt Nellie still makes me her signature casserole when I come to visit. This hash brown casserole recipe is a little taste of heaven. Save the leftovers and freeze them for another dinner or lunch. You might think the beef stock is an odd ingredient to use in this casserole. However, you don't actually taste it in the finished product; it is used to make the casserole creamier. You could use chicken stock in its place. Try Aunt Nellie's Hash Brown Casserole today...."
