Combine flour, yeast, and salt in a large bowl.
Add water and mix with a wooden spoon until all flour is incorporated.
The dough will be sticky but not runny.
Adjust water or flour as needed.
Cover and let the dough rise at room temperature for 2-3 hours, until it doubles in size and looks bubbly.
If it’s not rising, place it in a warmer spot.
For enhanced flavor, refrigerate the dough for up to 3 days.
If refrigerated, let it sit at room temperature for 45-60 minutes before baking.
Preheat a Dutch oven with its lid at 450°F (230°C) for 30 minutes.
Sprinkle flour on the surface and shape the dough by folding the edges inward.
Place the dough seam-side down onto parchment paper, and form it into a roundish shape.
Place the dough (with parchment) into the preheated Dutch oven.
Bake for 30 minutes covered, then another 12 minutes uncovered until golden brown.
Cool on a rack before slicing.
