In your mixing bowl, mix together the flour, salt, and yeast.
Add the water and mix to combine well.
Cover the mixing bowl tightly with plastic wrap and let the dough rise at room temperature for three hours.
Once risen, the dough should be puffy and bubbly. Move this dough to a well-floured surface and lightly dust the top of the loaf with more flour. Use your dough scraper to fold the dough over a bit and form a ball.
Move this dough ball to a sheet of parchment paper and put that in a bowl. Cover the bowl with a clean towel and let rise for 35 more minutes.
Preheat your oven to 450℉ with the dutch oven inside. Do this as soon as you're done with the previous step; you want the dutch oven thoroughly hot.
When the rise is done and the ovens are heated, carefully lift the dough using the parchment paper. Transfer it, paper and all, into the dutch oven.
Cover with the lid and bake for 30 minutes. Then, remove the lid and bake for another 10-15 minutes to firm up the crust.
When done, move to a cooling rack and let cool a bit before slicing to enjoy.
