Mix the Dough (No Kneading!): In a large bowl, whisk flour, yeast, and salt. Pour in the warm water and 2 tbsp olive oil. Mix with a spatula just until the flour disappears.
Pro Tip: The dough will be a sticky, shaggy mess. This is normal! Do not add more flour, or your bread will be dense.
The Long Rise: Drizzle the dough ball with a little oil to coat it. Cover with plastic wrap and place in a warm spot for 1.5 to 2 hours. It should double in size and become jiggly.
Fridge Option: For deeper flavor, let it rise in the fridge overnight (8-24 hours).
Pan & Second Rise: Generously oil your 9x13 pan (or skillets). Pour the dough in. Oil your hands (do not use flour!) and gently stretch the dough to fill the corners. Cover and let rise again for 30-45 minutes until it looks puffy and marshmallow-soft.
The "Dimple" & Flavor Infusion: Preheat oven to 425°F (220°C).
The Hack: Microwave the 4 tbsp topping oil with the smashed garlic and rosemary for 30 seconds to infuse the flavor. Remove garlic chunks if you don't want them to brown too much.
Dimple: With oiled fingers, poke deep holes all over the dough (touch the bottom of the pan!). Pour the herb oil into the holes and sprinkle with flaky salt.
Bake: Bake for 20-25 minutes until deep golden brown.
Crispiness Check: If using a glass pan, check the bottom to ensure it is browned; it may need 5 extra minutes.
Cool: Remove from pan immediately and cool on a wire rack to keep the crust crispy.
