Easy Same-Day Focaccia

1. Add the 2 cups warm water, yeast, and sugar to a large bowl. Mix and let sit for about 5 minutes.
2. Add the 2 tablespoons olive oil, salt and 4 cups flour. Mix with a wooden spoon or spatula until everything comes together. The dough should be very soft and sticky—don’t add more flour.
3. Cover the bowl and let the dough rise in a warm spot for about 45–60 minutes, until doubled and bubbly.
4. Generously coat a 9x13-inch pan with 2 tablespoons olive oil. Transfer the dough into the pan. With oiled hands, gently stretch it toward the edges. Don’t force it—if it springs back, let it rest for 10 minutes and try again.
5. Cover and let rise for another 30 minutes, until noticeably puffy.
6. Preheat the oven to 425°F. Drizzle 2 more tablespoons olive oil on top. Oil your fingers and press them all the way down into the dough to create deep dimples. Sprinkle with flaky salt and rosemary.
7. Bake for about 25-30 minutes, or until deeply golden on top and nicely browned underneath.
8. Let it cool for 10 minutes before removing it from the pan.
