Place water, 2 tablespoons olive oil, garlic, bread flour, 1 tablespoon rosemary, salt, and yeast into a bread machine in the order listed, or follow the order recommended by the manufacturer if different. Run the Dough cycle.

Remove the dough from the machine after the cycle is done and pat it into a 9x13-inch baking pan or a 12-inch pizza pan. Use your fingers to dimple the dough every inch or so. Brush with remaining 2 tablespoons olive oil and sprinkle with remaining 1/2 tablespoon rosemary. Cover with plastic wrap and let rest while the oven preheats.

Preheat the oven to 400°F (200°C).

Remove the plastic wrap and bake focaccia in the preheated oven until golden brown, 20 to 25 minutes.
