In a medium bowl, add the flour. On one side of the bowl, add the yeast. On the other side, add the salt. With a wooden spoon, stir to combine.
Add the warm water and gently stir to combine. The dough will be shaggy and messy, just make sure to have the flour completely combined.
Cover the bowl tightly with plastic wrap and foil. Let the dough ferment for 12- 24 hours, but no longer than that.
When the dough is ready, turn it out onto a floured counter. Use a a bench scraper to "fold" the dough into a round mound. Use two bench scrapers to lift the very wet dough onto a large piece of parchment paper. Spray a piece of cling wrap with oil and cover (oil side down) the dough. Let the dough rest for 30 minutes.
While the dough rests, place your Dutch oven into the oven and preheat it to 450°F. It's very important that your oven and pot be VERY hot, so let them heat for the full 30 minutes.
When the 30 minutes is up, take out the Dutch oven and transfer your parchment paper of dough into the pot and cover. Bake for 20 minutes.
Remove the lid and bake for an additional 30 minutes to brown the top.
Transfer the loaf to a cooling rack. Once it is cool enough to handle easily, you can begin tearing into it. If you want to cut the bread, wait until it has finished cooling.
