Heat the oven to 400 degrees. Line a large rimmed baking pan with parchment paper. In a large bowl, combine the oil, seasoned salt and pepper. Slice the potatoes into 1/2-inch thick slices and stir into the oil mixture until coated. Place the potatoes in a single layer on the baking pan. Bake for 40 minutes, turning halfway through baking, or until tender and browned. Divide the cheese and bacon among potato slices. Bake for 1 to 2 minutes longer or until the cheese melts. Dollop each potato slice with the sour cream and sprinkle with chives.
