Lightly oil a large baking tray with olive oil, using your fingers to spread it evenly. Don't add too much, just enough to prevent sticking.
Transfer the dough to the prepared tray. Let it rise at room temperature for about 1 hour, allowing it to relax and expand.
Lightly oil your hands with olive oil. Gently stretch the dough to the edges of the tray. Create dimples all over the surface with your fingers.
Distribute the halved kalamata olives, sun-dried tomatoes, and fresh rosemary sprigs evenly over the focaccia.
Important: If you rub your rosemary with olive oil, it won’t burn during baking.
Preheat your oven to 160°C (320°F) fan-assisted. Bake the focaccia for 35–40 minutes, or until golden brown. You can perform a toothpick test: if it comes out clean, your focaccia is done.
