To bake potatoes, preheat oven to 400 degrees. Scrub potatoes and prick with fork. Place on baking sheet and bake 45 – 60 Minutes, until done. Cool completely and cut baked potatoes into 1-in. cubes. In a large bowl, combine sour cream, cheeses, bacon, green onion, salt and pepper. Add potatoes. Spoon in to a greased 13-in. x 9-in. x 2-in. baking dish. When ready to cook, preheat oven to 375 degrees. Bake, uncovered for 40 minutes or until cheese is melted.
