MIX. In a large bowl, whisk flour, salt, and yeast until well mixed. Pour in warm water and use the handle of a wooden spoon to stir until a shaggy dough forms. The mixture will be wet and very sticky to the touch. *Do not over mix.
RISE. Cover bowl tightly with plastic wrap and set aside on countertop for 8 to 18 hours until dough rises, bubbles, and flattens on top. When the dough has fully risen, it will have doubled in size and be bubbly on top.
PREP. Prep your dutch oven. Heat oven to 450 degrees F. Once the oven is preheated, place a 6-quart Dutch oven (with cover) in the oven for 45 minutes before baking.
DOUGH. Generously flour a clean surface (I use a chopping block) and transfer the dough mixture to it, with floured hands, quickly shape the dough into a ball. Careful to not overwork the dough. Then lightly sprinkle the top of the dough ball with flour. Set aside while Dutch oven is heating.
BAKE. Remove Dutch oven from oven and carefully transfer the dough into it. (if the bottom of the Dutch oven isn't coated with enamel, place parchment paper beneath the mixture). Cover Dutch oven and return to oven. Bake bread 45 minutes covered, then another 10 minutes uncovered until dough is baked through and golden brown on top. Note: Because oven temperatures vary poke a toothpick into bread, if it comes out clean the bread is done. If it doesn't come out clean, then cook bread for another 5-10 minutes.
SERVE. Let cool slightly. Then slice using a bread knife and smear your favorite spread on top. ENJOY!
