01 - Dissolve yeast and sugar in warm water. Let stand 5–10 minutes until foamy.
02 - Combine bread flour and salt in a large bowl. Form a well in the center and add yeast mixture and olive oil.
03 - Mix with a wooden spoon until shaggy dough forms. Turn onto a floured surface and knead for 8–10 minutes until smooth and elastic.
04 - Place dough in an oiled bowl, cover with a damp towel, and let rise in a warm place until doubled in size, approximately 1–1.5 hours.
05 - Punch down dough and shape into a tight oval or round loaf. Place on a parchment-lined baking sheet dusted with cornmeal. Cover and let rise 45 minutes.
06 - Preheat oven to 425°F. Position an empty metal baking pan on the lowest rack.
07 - Slash the loaf top with a sharp knife. Pour 1 cup hot water into the empty pan to create steam.
08 - Bake on the center rack for 30–35 minutes until golden-brown and the loaf sounds hollow when tapped.
09 - Transfer to a wire rack and cool completely before slicing.
