In a large bowl, whisk together dry ingredients.
Add water and stir together using a rubber spatula. The dough will be wet and sticky at first, which is okay, but should not be “watery”.
Cover the bowl with plastic wrap and allow it to rise for 2 to 2½ hours in a warm place, or until tripled in size and bubbly (fluffy) in appearance.
Place dough onto a heavily floured surface and flour your hands. Shape the dough by stretching and folding the bottom of the dough up to the middle, then stretching and folding each side up and to the middle, and ending with stretching and folding the top of the loaf into the middle. Then, flip the dough over so that all of those seams are now on the bottom. Using cupped hands, push the dough in a circular motion to form it into a dough ball.
Line a Dutch oven with parchment paper. Place the ball of dough into the lined Dutch oven. Lightly flour the top of the dough ball and cover with plastic wrap. Allow the dough to rest for 30 minutes.
Preheat the oven to 450°F.
Using a very sharp knife like a paring knife or a bread lame, score the top of the loaf with an “x”.
Cover and bake for 30 minutes.
After baking for 30 minutes, uncover and continue to bake for 15 additional minutes or until golden brown on top. Carefully remove the loaf from the Dutch oven and allow it to cool for 30 minutes. Slice and serve.
