How to make sourdough bread in a loaf

Take a cast iron pot, place the loaf pan inside, line the aluminum loaf pan with unbleached parchment paper, then place your dough inside. Cover the cast iron pot. Bake on your normal sourdough temperature (450).
Since the sourdough is in a second container within the cast iron pot, it can add 3-4 extra minutes to the bake time.
