In a large bowl, whisk together the flour, salt, and yeast. Add the warm water to the flour mixture and stir until all the flour is incorporated and a sticky dough forms—no kneading required.

Pour the 1/4 cup of olive oil in a large bowl and do a swirl to move it around. Transfer the focaccia dough to the bowl and turn to coat so nothing is sticking. Place a hot towel on top of the bowl and let it proof for 1.5 - 2 hours.

When you're ready to bake, lightly oil a baking sheet and pour the dough onto the sheet. Spread it as much as you can, and make sure it doesn't stick. Proof it in the oven (if possible) for another hour. If not, leave it in a slightly warm area.

Preheat the oven to 450 degrees Fahrenheit.

Pat down the focaccia dough until even thickness and then make indentations with your fingers like you're playing a chord on the dough. Dimple the entire dough and sprinkle with more olive oil, rosemary, cracked pepper, and coarse salt.

Bake for 15-19 minutes until golden brown.

And you're done!! ?
