In a large mixing bowl, combine the flour, yeast, and salt.

Add the warm water and olive oil, and mix until a sticky dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth.

Place the dough in a greased bowl, cover with plastic wrap, and let it rise for 1 hour or until doubled in size.

Preheat the oven to 425°F (220°C).

Grease a baking sheet with olive oil.

Transfer the risen dough to the baking sheet and stretch it out to fit the pan.

Dimple the surface with your fingers, drizzle with olive oil, and sprinkle with sea salt and rosemary.

Bake in the preheated oven for 20-25 minutes until golden brown.

Remove from the oven and let cool slightly before slicing.
