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. Mix until a shaggy dough forms, then knead by hand or stand mixer for 5–7 minutes until smooth and slightly tacky.
03 - Drizzle in 1 tablespoon olive oil, chopped rosemary, and minced garlic. Knead briefly until evenly distributed throughout the dough.
04 - Transfer dough to a lightly oiled bowl, cover with a damp towel, and place in a warm area for 1 hour until doubled in volume.
05 - Coat a 10-inch oven-safe skillet generously with olive oil. Punch down risen dough and press into the skillet, spreading evenly to the edges. Cover and let rise for 25–30 minutes.
06 - Heat oven to 425°F.
07 - Brush dough surface with remaining olive oil and sprinkle evenly with flaky sea salt.
08 - Bake for 30–35 minutes until deep golden brown and bread sounds hollow when tapped on the bottom.
09 - Let cool in the skillet for 10 minutes before slicing into wedges. Serve warm.
