Incredible Potato Casserole

Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 2 1/2 quart casserole dish.

Place whole potatoes in their skins into a large pot of boiling water; cook for 25 to 30 minutes. Remove potatoes and discard water. When cool enough to handle peel potatoes and grate into a medium bowl.

In a resealable bag shake together the cornflake crumbs and 2 tablespoons melted butter. Sprinkle over top of casserole.
