In a mixing bowl, combine all-purpose flour, salt, and instant yeast. Gradually stir in olive oil and warm water until a sticky dough forms. Cover with plastic wrap and let it rise in a warm area for 1-2 hours until doubled in size.

Grease a 9x13-inch baking dish with olive oil. Transfer dough to the pan, stretching to reach edges. Rest for 30 minutes.

Combine additional olive oil with minced garlic and a pinch of salt in a small saucepan. Heat gently over low flame for 2-3 minutes until fragrant. Cool slightly.

Press deep dimples into the dough, drizzle cooled garlic oil over the surface, and sprinkle with Parmesan cheese and fresh herbs.

Preheat oven to 425°F (220°C) and bake focaccia for 20-25 minutes until golden brown.

Let the focaccia cool in the pan for about 10 minutes, then cut into squares or strips for serving.
