Aunt Laurie's Ooey-Gooey Potatoes

Just. So. Yummy.

Aunt Laurie's Ooey-Gooey Potatoes
2 1/2 pounds of potatoes, boiled, peeled and cubed. (This was about 6 regular size potatoes)
1/2 medium onion, chopped
1/2 cube of butter
4 oz. cream cheese
1-2 cans of Cream of Mushroom soup (depends on how saucy you want them)
8 oz. sour cream
4 oz. shredded cheddar cheese

In a large saucepan melt the butter. Stir in the cream cheese until its melted and smooth. Add the soup, and sour cream.  Once its warm and well blended, add in the cheddar cheese and stir until its melted.

In a large crockpot, mix together the potatoes and onion. Pour the cheesy mixture over the top and stir everything until the potato mixture is well-coated. Cook on HIGH for 2-3 hours.
