Raise the heat to high and cook undisturbed until the bottom layer is deep brown, about 3 minutes. Using the spatula, lift the browned bits from the bottom of the pan and stir into the upper layers. Repack the skillet and repeat three or four times, until the entire skillet is full of well-browned potatoes, about 10 minutes total. Reduce the heat to low.
