Combine Dry Ingredients: In a large bowl, whisk together the flour, yeast, garlic, rosemary, salt, and sugar.
Add Wet Ingredients: Pour the warm water and olive oil into the dry ingredients. Stir until a dough forms.

Preheat Oven: Preheat your oven to 450°F (230°C).
Shape the Loaf: Turn the risen dough onto a lightly floured surface and shape it into a loaf. Place it on a baking sheet lined with parchment paper.
Slash the Loaf: Use a sharp knife to slash the top of the loaf a few times.
Bake: Bake for 20-25 minutes, or until golden brown and crusty.
Serve: Let cool slightly before serving.
