Combine the flour, yeast, and salt in a large mixing bowl, add the warm water, and stir with the handle of a wooden spoon until the dough is wet, sticky, and all the flour is mixed in.
Cover the bowl with cling wrap or a plate, set it on the counter, and let the dough rise for 2 to 3 hours until it doubles in size, looks bubbly on top, and jiggles when you shake the bowl.
About 30 minutes before baking, place a Dutch oven with its lid into the oven and preheat to 230°C/450°F (220°C fan); if the dough was refrigerated, let it rest on the counter during this time.
Sprinkle flour on your work surface, scrape out the dough, dust the top with more flour, and fold the edges inward about 6 times to form a rough round shape.
Place a large piece of parchment paper beside the dough, flip the dough onto the paper seam-side down, and gently shape it into a round without worrying about perfection.
Carefully take the hot Dutch oven out of the oven, use the parchment paper to lower the dough inside, cover with the lid, and bake for 30 minutes.
Remove the lid and bake for another 12 minutes until the crust is deep golden and crisp.
Lift the bread out of the pot with the parchment paper, set it on a rack, and cool for at least 10 minutes before slicing.
