Grease a 9x13 inch (23x33cm) pan generously with olive oil to prevent sticking and add flavor.
Carefully turn the dough out into the prepared pan. Gently shape it into a rough rectangle without pressing too hard to preserve the dough’s airiness. Let it rest in the pan for 5 minutes, allowing it to relax.
After resting, use your oiled fingers to gently stretch the dough towards the edges of the pan. Work from the center outward, being careful not to deflate the dough. If the dough resists stretching, let it rest for a few more minutes and try again.
Once the dough is spread to the edges, cover the pan with a clean kitchen towel or plastic wrap. Let it rest at room temperature for 2 to 3 hours, allowing it to rise and fill the pan. The dough should become puffy and soft during this time.
Preheat the oven to 425°F (220°C).
Drizzle olive oil over the surface of the dough.
Using your fingertips, press into the dough to create dimples all over the surface.
Now, add your favorite toppings. In this case, top the dough with halved cherry tomatoes, slices of red onion, fresh rosemary sprigs, and a sprinkle of flaky sea salt.
Bake the focaccia for about 25 minutes until golden brown and crispy around the edges.
Optional: After baking, drizzle a little more olive oil over the focaccia for extra richness and shine.
Allow the focaccia to cool in the pan for 5 minutes before carefully transferring it to a wire rack to cool completely. This ensures the bottom stays crisp and doesn’t become soggy.
