Instructions
In a large bowl, combine yeast with warm water and sugar. Stir gently to dissolve. Let stand 3 minutes until foam appears. Slowly add the flour to the bowl. Dissolve salt in 2 tbsp. of water and add it to the mixture. Pour in 1/4 cup olive oil. When the dough starts to come together, mix with your hands until the dough is smooth and elastic, adding flour as necessary.
Turn the dough out onto a work surface and fold it over a few times. Form the dough into a round. Spread a layer of olive oil inside the mixing bowl with your hands, and place the dough inside. Turn to coat the entire ball with oil. Cover with plastic wrap or damp towel and let rise in a warm place until doubled in size, about 30 minutes.
Coat a sheet pan with a little olive oil and corn meal. Once the dough is doubled in size, place it on a work surface. Roll and stretch the dough into a rectangular shape about 1/2-inch thick. Lay the flattened dough on the pan and cover with plastic wrap.
In the meantime, heat 1 tbsp. oil in a small saute pan. Add the onion and cook over low heat for 10 minutes until the onions caramelize.
Preheat oven to 400 degrees. Uncover the dough and dimple with your fingertips. Brush the surface with more olive oil and then add caramelized onions, garlic, cheese, salt, pepper, and rosemary. Bake on the bottom rack for 15 to 20 minutes. Let cool about one hour before slicing.
