The key to a great dinner party or holiday dinner is to make anything and EVERYthing ahead of time as possible! Last minute things should be minimal. When you do this, you will have a stree-free dinner and get to spend time with your guests instead of being all tied up in the kitchen. This recipe is a life saver!! :D

Place potatoes in large pot, cover with water, and bring to a boil. Reduce heat, cover, and cook for 20-25 minutes or until potatoes are tender. Drain potatoes, place in large bowl, and mash with sour cream, cream cheese, onions, salt, and 4 tablespoons of butter, stirring until butter and cream cheese have melted. Spread potatoes into greased 13 x 9 baking dish. Melt remaining butter and drizzle over potatoes. Sprinkle with paprika, cover, and refrigerate until ready to use (you can bake these right away, of course). Refrigerated potatoes need to sit at room temperature for 30 minutes before baking. Cover with tin foil and bake at 350 degrees for 40 minutes, then remove foil and bake for another 20 minutes. Remove from oven and add additional pats of butter and parsley if desired.
