Add water to a large bowl of electric mixer.
Sprinkle yeast on top
With mixer running, slowly add flour and salt.
Mix until well combined. This will be a wet, sticky dough.
Transfer to a very large food safe container, cover with plastic wrap. This dough will more than double in size.
Place in a cool area overnight. You can use the dough after a few hours or let sit for several days.
When ready to use, place a large piece of parchment paper on the counter. Lightly spray parchment paper. Plop dough onto paper.
With wet hands, to prevent sticking, form into a rough rectangle. Gently fold one side over to the middle. Fold each side into the middle forming a package.
Carefully, but quickly, flip dough over so the seems are on the bottom.
Cover loosely with a lightly sprayed piece of plastic wrap.
Meanwhile, place a dutch oven with lid into the oven. Heat oven to 450 degrees. Heat dutch oven for at least 30 minutes in oven.
When dough has risen (about 30 minutes), open oven door, slide out oven rack and carefully open lid.
Grab all four corners of parchment paper and carry to the oven and place in dutch oven. Replace lid.
Cook for 40 minutes.
Remove lid and continue cooking for an additional 15 minutes.
Cool on a baking rack until completely cooled. Slice and enjoy!
