This was supposed to be a recipe for potato patties, but they didn't hold together too well - fortunately, it makes a really yummy mashed potato side :)
5 lbs yukon gold potatoes, cubed
1 8oz package cream cheese
4 tbsp butter
1/2 onion, grated
generous dash pepper
Peel and boil potatoes until crumbly (about 10-15 minutes). In bowl of mixer, place potatoes, cream cheese, butter, onion and pepper. Mix on low speed until creamy. Chill thoroughly. Heat oil in large frying pan over medium heat. Place potatoes in pan, spread evenly, and fry until bottom turns golden. Flip potatoes and fry until bottom is golden. Stir and serve.
