Sometimes this is called cheesy potatoes and in Utah it is often called "funeral" potatoes because it is a great dish for funeral luncheons. I just made this for the funeral luncheon of my neighbor who was a wonderful cook and a great neighbor. It is a yummy, cheesy side dish.
Melt 1 cube butter, 1 can cream of chicken soup and 1 pint of sour cream. Mix it with 24-36 ounces of frozen hash browns, thawed, and 2 c. grated cheese. Pour into a 9" x 13" pan. Crush 1 c. corn flakes and mix with 2 T. melted butter. Sprinkle on top of potatoes. Bake at 350° for 25-30 minutes. (You can also boil or bake 8 potatoes, cool them and grate them instead of using frozen hash browns.)
