Combine all ingredients in a large bowl, stirring until well combined. The dough will form a shaggy ball and will be messy.
Cover tightly with plastic wrap. Allow to rise, at room temperature, for 8 hours or overnight.
Remove the dough onto a floured surface, and gently form into a round loaf. Cover with a towel, and allow to sit for one hour.
About 30 minutes before the dough is ready, preheat the oven to 450 degrees F. Place a Dutch oven or baking crock with a lid in the oven, and let that preheat as well. When dough is ready, gently slide dough into Dutch oven. Cover it with the lid, and cook for 30 minutes. Remove the lid and bake for another 10-25 minutes, until the top is crusty and deep down.
Remove from oven and from pot. Let cool completely.
