In a large bowl, combine the flour, salt, sugar, and yeast. Gradually add the warm water and stir until a sticky dough forms. If the dough seems dry, add 1 more tablespoon of water at a time until it's no longer dry.
Cover the bowl with a clean, damp dish towel and set it in a warm place to rise for 2 hours or up to overnight in the fridge. If the dough is refrigerated overnight, let it sit at room temperature for about 30-45 minutes before baking.
About 30 minutes before the dough is done rising, preheat your oven to 450°F, placing a covered 2 3/4 quart Dutch oven (or similar size baking dish) inside to preheat.
Place a large square of parchment paper on the counter and sprinkle it with flour. Transfer the dough to the floured parchment paper, gently folding it on top of itself a few times to form a round loaf. Let it rest on the parchment while the oven finishes preheating.
Carefully remove the hot Dutch oven from your oven. Using the parchment paper, transfer the dough into the Dutch oven and replace the lid.
Bake for 35 minutes, then remove the lid and bake for an additional 10-15 minutes until the crust is golden brown and it feels hollow when you tap on it.
Remove the Dutch oven from the oven, and carefully lift the bread out using the parchment paper. Let it cool on a rack for about 30 minutes before slicing.
