Stir first 5 ingredients together in large bowl, and then stir in warm water. The dough will be sticky. Gently shape dough into a ball as best you can. Cover tightly. Set on counter at room temperature and allow to rise for 12-18 hours. The dough will double in size and have a lot of air bubbles.
Turn dough out onto a lightly floured work surface and using lightly floured hands, shape into a ball as best you can. Transfer dough to a large piece of parchment paper. Place ball of dough and parchment inside a bowl so dough doesn’t spread out as it rests.
Gently score an “X” into top. Cover dough lightly and let it rest for 30 min. Preheat oven to 475ºF. Place Dutch oven with lid inside oven for 30 min. so it’s extremely hot before dough is placed inside. After 30 min., remove Dutch oven from oven and carefully place dough inside by lifting it up with parchment paper and placing it (parchment paper included) inside pot. Cover with lid. Bake for 25 min. with lid on. Carefully remove lid and continue baking for 8-10 min. until bread is golden brown.
