Add the potatoes to the pan and drizzle with the remaining 1 tablespoon oil. Sprinkle with salt and pepper and spread them evenly in a single layer on the pan. Cover tightly with foil and bake for 5 to 10 minutes. Remove the foil and bake until the bottoms are golden brown, about 10 minutes. Flip with a spatula and cook until the other side is golden brown, another 10 to 13 minutes.
