Party Potatoes

In a large saucepan, cook potatoes in boiling salted water until tender, drain. Mash potatoes with butter milk, salt and pepper until smooth. Add cream cheese and onion dip; mix well. Spread in a greased 2 1/2 qt. baking dish. Sprinkle with paprika.

Cover and refrigerate for 8 hours or overnight. Remove from the refrigerator 30 minutes before baking. Bake, uncovered at 350 degrees for 50 to 60 minutes or until heated through.
