Combine all ingredients in a medium-large bowl and mix into shaggy dough with dough whisk or wooden spoon.
Cover dough and leave on countertop for 18-24 hours.
About 1 hour before baking, prehead oven to 450°F, place dutch oven with lid in oven while oven preheats.
After dutch oven has been in preheated oven for 30-60 minutes, lightly flour a piece of parchment and transfer dough from bowl to parchment.
Dough will be somewhat loose, fold in edges towards center creating tension in dough. Dough will not form a tight ball, and will flatten out a little.
Carefully remove dutch oven from oven, and place bread on parchment inside dutch oven, replacing the lid before putting back in oven.
Bake for 30 min. After 30 min, remove lid of dutch oven and bake for another 20-25 minutes until crust of bread is a deep golden brown.
Carefully remove bread from dutch oven and let cool on a wire rack for at least 1 hour before cutting into bread.
