In a large bowl, combine the warm water, sugar, and yeast. Let it sit for 5-10 minutes until it becomes foamy.

Add the flour and salt to the yeast mixture and stir to combine. Add the olive oil and knead the dough until smooth and elastic, about 8-10 minutes. Cover and let the dough rise for 1 hour or until it has doubled in size.

While the dough is rising, heat olive oil in a skillet over medium heat. Add the sliced onions and cook slowly for 20-30 minutes, stirring often until golden and caramelized. Set aside to cool.

Punch down the dough and transfer it to a floured surface. Roll it into a 12×8 inch rectangle. Spread the caramelized onions evenly over the dough and sprinkle with both cheeses.

Roll the dough up like a jelly roll and pinch the seams to seal. Place it into a greased baking dish and let it rise for 30 minutes.

Preheat the oven to 375°F (190°C). Bake the bread for 25-30 minutes, until the top is golden and the cheese is bubbly. Tap the bottom of the loaf—if it sounds hollow, it’s done.

Let the bread cool for 10 minutes before slicing. Enjoy warm!
