01 - Whisk together warm water and yeast in a large bowl. Let stand for 5 minutes until foamy.
02 - Add bread flour and salt to the yeast mixture. Stir until a shaggy dough forms, then knead by hand or with a mixer for 5–7 minutes until smooth and slightly tacky.
03 - Drizzle in 1 tablespoon olive oil, chopped rosemary, and minced garlic. Knead briefly to distribute evenly throughout the dough.
04 - Place dough in a lightly oiled bowl, cover with a damp towel, and set in a warm area. Let rise for approximately 1 hour until doubled in volume.
05 - Generously coat a 10-inch oven-safe skillet with oil. Punch down risen dough and transfer to the skillet, pressing gently toward the edges. Cover and let rise for 25–30 minutes.
06 - Heat oven to 425°F.
07 - Brush the dough surface with remaining olive oil and scatter flaky sea salt evenly over the top.
08 - Bake for 30–35 minutes until the bread is deeply golden and sounds hollow when tapped.
09 - Allow bread to cool briefly in the skillet before slicing. Serve warm for optimal texture.
