01 - In a large bowl, mix bread flour, instant dry yeast, and sea salt thoroughly.
02 - Add warm water and olive oil to the dry ingredients. Stir until a sticky dough forms.
03 - Knead on a lightly floured surface for 8 to 10 minutes until smooth and elastic, or use a stand mixer with a dough hook for 6 to 8 minutes.
04 - Place dough into a clean, oiled bowl. Cover with plastic wrap or a damp towel and allow to rise in a warm place until doubled in size, approximately 1 hour.
05 - Lightly oil a 9x13 inch baking pan. Transfer dough to the pan, gently stretching it to fit. Cover and let it rise again until puffy, about 30 to 40 minutes.
06 - Preheat oven to 425°F. In a small bowl, combine olive oil, minced garlic, and chopped rosemary.
07 - Using fingers, create indentations across the surface of the dough. Drizzle the garlic-herb oil evenly over, making sure to fill the dimples. Sprinkle with flaky sea salt.
08 - Bake in the preheated oven for 22 to 25 minutes, until golden brown and crisp on top.
09 - Allow to cool slightly before slicing and serving.
