5 pounds potatoes, washed, peeled and diced
2 Tbsp. Butter
8 oz. Cream cheese
8 oz. Sour cream
2 tsp. Garlic Salt
Chopped Chives, optional
Bring water to a boil and cook potatoes until tender. Place into mixer add butter, and mash potatoes. Add cream cheese, sour cream, and garlic salt. Beat until fluffy. Pour into greased 9x13 casserole dish top with chives if wanted. Cover with foil.
