In a bowl, mix warm water and yeast. Let it sit for 5–10 minutes until foamy.
Add flour, salt, and olive oil. Mix until dough forms, then knead until smooth, about 8 minutes.
Place dough in a greased bowl, cover, and let rise for 1 hour until doubled.
Punch down the dough and transfer to a greased baking pan. Press dough out evenly and poke dimples across the surface with your fingertips.
Drizzle olive oil over the top. Sprinkle with garlic, parmesan, and rosemary if using.
Let dough rise again for 20 minutes. Preheat oven to 400°F (200°C).
Bake for 20–25 minutes until golden brown. Slice and serve warm.
