Boil potatoes (not soft). Cool, peel, grate on large grater. Set aside. Heat butter and soup; blend in sour cream, onions and cheese. Stir in potatoes. Put in 2 1/2 qt. Casserole. Top with 2-4 cups crushed corn flakes mixed with 2 Tbps. Melted butter, if desired. Bake 45 minutes at 350 degrees.

These are sooo good! I do most of them early, and then bake them with the rest of the meal. They are a little bit of work, but doing it that way I can clean up most of the mess ahead of time. Hope you enjoy.
