Rosemary Focaccia

Directions

• In a large skillet, heat 1/4 cup oil over medium heat. Add onions; cook and stir until tender, 6-8 minutes. In a large bowl, dissolve yeast in 1/4 cup warm water. Add sugar; let stand 5 minutes. Add 2 tablespoons oil, salt and remaining water. Add 2 cups flour. Beat until smooth. Stir in enough remaining flour to form a soft dough.
• Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Add onions and 1 tablespoon rosemary. Knead 1 minute longer. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 40 minutes.
• Punch dough down. Turn onto a lightly floured surface; divide in half. Pat each piece flat. Let rest 5 minutes. Grease two baking sheets and sprinkle with cornmeal. Stretch each portion of dough into a 10-in. circle on prepared pans. Cover and let rise until doubled, about 40 minutes. Preheat oven to 375°.
• Brush with remaining 1 tablespoons oil. Sprinkle with coarse salt and remaining 1 tablespoon rosemary. Bake until golden brown, 25-30 minutes. Remove from pans to wire racks. Serve warm.
