Baked Potato Casserole

I got this recipe from my sister. We made it for christmas day dinner and it was very tasty

8 baking potatoes.
1 cup sour cream
8 oz package cream cheese, softened
4 tablespoons butter
1/3 cup chopped chives
Salt

Peel potatoes, quarter and boil until tender. Drain water, add butter, mash potatoes until smooth.
Blend in mixer, sour cream and cream cheese until smooth. Combine mixture with mashed potatoes. Add chopped chives. Add Salt and pepper to taste. Put in 2 quart casserole dish greased with butter. Sprinkle paprika on top. Bake at 350 degrees for 25 minutes.
Tip: once mixed together, check consistency. If too dry, add more sour cream until smooth and creamy.
