Preheat oven to 200F. Once it is up to temperature turn it off. Place the dough in an oiled ovensafe dough and let proof in the warm oven for about an hour. (Should double or more)
Punch the dough down and split in three equal parts.
Fold each piece into a loaf shape and place in a greased loaf pan.
Let the dough proof again, covered and not in the oven this time, for another hour or so. Dough should fill or overfill the loaf pans when done proofing.
