01 - In a large bowl, whisk together the warm water and yeast. Allow to sit for 5 minutes until foamy.
02 - Add bread flour and salt. 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, rosemary, and minced garlic. Knead briefly to incorporate.
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 turn it out into the skillet, pressing it gently to the edges. Cover and let rise for 25–30 minutes.
06 - Preheat oven to 425°F.
07 - Brush dough with remaining olive oil and sprinkle with flaky sea salt.
08 - Bake for 30–35 minutes, or until bread is golden and cooked through.
09 - Cool slightly before slicing. Serve warm.
