20 ounces all-purpose flour (use bread flour if you have it)
8 ounces water
4 ounces melted butter with chopped herbs (I used about 2 tablespoons of thyme)
2 teaspoons salt, plus more for sprinkling
1 teaspoon instant yeast
Extra-virgin olive oil
Combine all of the ingredients in a stand mixer fitted with the dough hook. You can also do this by hand in a large bowl. Mix or knead for about 10 minutes until you achieve a windowpane with the dough.
Cover the dough with plastic wrap and let it sit 1-4 hours until it has doubled in size. Once the dough has doubled, knead for 1-2 minutes to let the yeast redistribute.
Preheat the oven to 400 degrees. Coat the dough with olive oil and sprinkle the top with extra kosher salt. Cut a large "X" into the top of the dough. Bake in a covered cast iron pan* for 30 minutes. Remove the lid and cook an additional 15-20 minutes until browned.
*I used a stainless steel dutch oven since I don't have a cast iron pan.
