Cook potatoes in boiling water for approximately 30 minutes or until tender. Drain and mash.
Beat cream cheese with electric mixer until smooth. Add potatoes and remaining ingredients, except paprika; beat just until combined. Spoon mixture into a lightly buttered 2-quart casserole; sprinkle with paprika. Cover and refrigerate overnight.
Remove from refrigerator 15 minutes before baking. Uncover and bake at 350 degrees F for 30 minutes
