Step 1

Mix flour, salt, and yeast together in a glass or ceramic bowl; add water. Cover with plastic wrap and set aside at 70 degrees F (21 degrees C) for 12 to 19 hours.

Step 2

Turn dough out onto a floured cutting board covered with waxed paper. Dough will be sticky. Turn 2 to 3 times so that all sides are well floured. Set aside, covered with waxed paper, until doubled in size, about 2 hours.

Step 3

Place a Dutch oven in the oven. Preheat the oven to 475 degrees F (245 degrees C).

Step 4

Carefully remove the Dutch oven, place dough inside, and cover with the lid.

Step 5

Bake in the preheated oven for 30 minutes. Remove the lid and continue to bake until the crust achieves your desired color, 10 to 20 minutes more.
