In a mixing bowl, combine warm water, yeast, and sugar. Stir and let it sit for 5–10 minutes until foamy.
Add flour, olive oil, and salt. Mix until dough forms. Knead for about 5 minutes until smooth.
Cover the bowl with a towel and let the dough rise in a warm place for 45–60 minutes until doubled in size.
Preheat the oven to 375°F. Grease a muffin tin with olive oil.
Punch down the dough and divide it evenly into 12 muffin cups.
Mix rosemary and garlic with a little olive oil. Brush the tops of the dough with this mixture.
Sprinkle sea salt over each muffin. Bake for 20–25 minutes or until golden brown.
Let cool slightly before serving. Best enjoyed warm!
