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 - Place dough in a greased bowl, cover with a damp kitchen towel, and let rise in a warm location for 1 hour or until doubled in bulk.
05 - Generously oil a 10-inch oven-safe skillet. Punch down risen dough and transfer to the skillet, pressing gently to evenly cover the bottom. Cover and let rise for 25-30 minutes.
06 - Set 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 deeply golden and sounds hollow when tapped on the bottom.
09 - Let bread cool in the skillet for 10 minutes before slicing. Serve warm for optimal texture.
