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 to form a shaggy dough, then knead by hand or mixer for 5–7 minutes until smooth and slightly sticky.
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 greased bowl, cover with a damp towel, and let rise in a warm place for 1 hour or until doubled in size.
05 - Generously oil a 10-inch oven-safe skillet. Punch down dough and press it gently into the skillet, spreading to the edges. Cover and let rise for 25–30 minutes.
06 - Preheat 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 bread is golden brown and cooked through.
09 - Let cool slightly before slicing into 8 pieces. Serve warm.
