Working on a lightly floured surface, gently shape dough into a round.
Place dough into the prepared skillet. Cover with a clean dishtowel and let stand at room temperature until dough has doubled in size and does not readily spring back when poked with a finger, about 2 hours.
Preheat oven to 450 degrees F. Place into oven and bake until golden brown, about 30-40 minutes.
