Combine 1.5 cups warm water, one packet (2.25 tsp) yeast, and ½ tbsp salt in a large bowl, stirring until dissolved.
Add 3.25 cups flour and mix into a sticky dough.
Adjust with flour or water as needed.
Cover the bowl and let the dough rise in a warm place for 2-3 hours until doubled.
Preheat the oven to 450°F and place the Dutch oven with the lid on inside to heat for 20 minutes.
Scrape the dough onto floured parchment paper and shape into a loaf by folding the edges.
Flip the dough so the floured side faces up and center it on the parchment.
Optionally, score the top of the loaf with shallow cuts for decoration.
Remove the hot Dutch oven from the oven and carefully take off the lid.
Transfer the dough, along with the parchment, into the Dutch oven.
Cover with the lid and bake for 35 minutes (40 if dough is cold).
Remove the lid and bake for another 5-10 minutes until golden brown.
Let the bread cool on a wire rack for at least 10 minutes before slicing.
When the bread is cooled it is ready to be served.
