In a large bowl (or container), mix together the 1 ½ cups warm water, 1 packet yeast (or 2.25 teaspoons), and 1 ½ teaspoons fine grain salt, until yeast and salt are fully or almost dissolved.
Add the 3 ¼ cups all-purpose flour to the bowl all at once and stir together until a sticky dough forms.
Cover the bowl with a kitchen towel and leave it for 2-3 hours to rise in a somewhat warm place until it's doubled in volume.
30 minutes to an hour before you are ready to bake, preheat your oven to 450 degrees F. Place your Dutch oven in the oven, with the lid ON, while the oven is preheating.
Scrape the dough into the edge of a piece of parchment paper dusted with flour and shape it into a loaf.
Use the edges of the parchment paper to flip the loaf over so the floured side is on top.
Optional: use a very sharp knife to cut a few slits across the top of the loaf about ½" deep.
Take out the preheated Dutch oven and take off the lid, carefully! Place the loaf in your Dutch oven.
Place the cover back on the Dutch oven and bake for 35 minutes at 450 degrees F.
Remove the lid and bake for another 5-10 minutes, until a golden brown color forms.
Remove the loaf from the dutch oven and place it on a wire rack or cutting board to cool for at least 10 minutes before slicing.
