This cheesy onion focaccia bread is soft, golden, and loaded with caramelized onions and melty cheese. Perfect as a side, snack, or sandwich base, it’s savoury, aromatic, and wonderfully satisfying right out of the oven.
In a large bowl, dissolve yeast and sugar in warm water. Let sit for 5–10 minutes until foamy. Stir in flour, salt, and olive oil. Knead into a soft dough. Cover and let rise for 1 hour or until doubled.
Prepare the Onions:
While the dough rises, sauté onions in 1 tablespoon olive oil over medium heat until golden and soft, about 10–12 minutes. Set aside.
Shape and Top:
Punch down the dough and spread it in a greased 9x13-inch pan. Use fingers to dimple the surface. Top with caramelized onions, mozzarella, Parmesan, oregano (if using), and a sprinkle of coarse salt.
Bake:
Bake at 400°F (200°C) for 20–25 minutes until golden brown and bubbly.
Cool and Serve:
Let cool slightly before slicing and serving warm.
