In a large bowl, combine flour, salt, and active dry yeast. Stir together.
Heat water to 100-110 degrees F and pour it into the flour mixture. Stir together until all of the flour is incorporated. You can use your hands to gently work the dough together. Stop as soon as all of the flour is incorporated.
Cover bowl with plastic wrap or a clean towel and place in a warm spot to rise for 2 hours.
Thirty minutes before the dough finishes rising, place the lid on your Dutch oven and place it in the oven. Preheat oven to 450 degrees F.
When the dough has finished proving, lightly flour a flat surface and scoop the dough out of the bowl and place it on the floured surface.
Gently form the dough into a round loaf and lightly score the top with a sharp knife. Place the dough on a large piece of parchment paper.
Carefully remove the Dutch oven from the hot oven, open the lid, and lift the dough on the parchment paper into the Dutch oven. Cover with the lid and place the Dutch oven back in the hot oven to bake for 30 minutes.
After 30 minutes, remove the lid and continue to bake for 15 minutes.
Remove from the oven and carefully take the bread out of the Dutch oven. Set the bread on the counter and let it cool completely before slicing.
