In a large bowl, whisk together 4 1/2 cups flour, yeast, sugar, and salt. Add the warm water and olive oil, then stir until a rough, shaggy dough forms. Add more flour only if the dough is soupy.
02 -
Turn the dough onto a lightly floured surface. Knead for 6-8 minutes, until smooth, stretchy, and slightly tacky. If using a stand mixer, knead with the dough hook for about 6 minutes on medium-low speed.

Place the dough in a lightly oiled bowl and turn it once to coat. Cover and let rise in a warm spot until doubled, about 1-1 1/2 hours.
04 -
Gently deflate the dough and divide it in half. Shape each piece into a short log, tucking the edges under to create surface tension. Place on a cornmeal-dusted baking sheet.

Cover loosely and let rise until puffy, 35-45 minutes. Heat the oven to 425°F. Dust the loaves lightly with flour and cut 3 shallow diagonal slashes across each top.

Bake for 25-30 minutes, until deeply golden and hollow-sounding when tapped underneath. The center should read about 190°F. Cool on a wire rack for at least 20 minutes before slicing.
