01 - Combine bread flour, instant dry yeast, and fine sea salt in a large bowl and stir to blend thoroughly.
02 - Add warm water and olive oil to the dry ingredients. Stir until a sticky dough forms.
03 - Knead the dough 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 in a clean, oiled bowl. Cover with plastic wrap or damp towel and let rest in a warm spot for 1 hour until doubled in size.
05 - Lightly oil a 9x13-inch baking pan and transfer the risen dough. Gently stretch the dough to fill the pan evenly.
06 - Cover the dough and allow it to rise for another 30 to 40 minutes until puffy.
07 - Preheat the oven to 425°F (220°C).
08 - In a small bowl, combine olive oil, minced garlic, and chopped rosemary.
09 - Using fingers, dimple the dough surface. Drizzle the garlic-herb oil over the top, ensuring it fills the indentations, then sprinkle flaky sea salt evenly.
10 - Bake for 22 to 25 minutes until the top is golden brown and crisp.
11 - Allow the bread to cool slightly before slicing and serving.
