Mix flour, yeast, and salt in a large bowl.
Make a well in the flour mixture and add lukewarm water.
Mix with a wooden spoon for up to a minute, until the dough becomes too sticky to be pancake batter but too runny to be playdough.
Cover the bowl with a kitchen towel and set it in a nice warm place in your house. After about 6 – 8 hours, the dough should have doubled in size.
Either lightly flour a piece of parchment paper or use a silicone mat and slide the dough onto it.
Punch down the dough and gently fold it a couple times.
Form it into a ball (sprinkle some flour on your hands if it’s too sticky) and cover with a towel. Let rise for another 1-1/2 hours.
Start preheating the oven about 30 minutes before the dough is ready. Line the Dutch oven with parchment paper and place it (with the lid on) in the oven (on the middle rack) while preheating.
When the oven lets you know it has reached 425℉, take the really, really hot Dutch oven out.
Place the dough into the Dutch oven, put the lid back on, and then put it back in the oven.
Thirty minutes later, remove the lid and let it bake for another 20 minutes or until it’s nicely browned.
Let cool completely on a rack and enjoy!
