Caramelized Onion Focaccia

This is bakery-style focaccia made attainable by using a bread machine for the dough. The result has the proper focaccia signature: a chewy, olive-oil-rich crumb, characteristic finger-dimpled surface, and a generous topping of sweet caramelized onions, melted mozzarella and grated parmesan. It works as an appetizer with wine or alongside an Italian dinner.

The caramelized onions are the topping’s flavor centerpiece and worth the full 15 to 20 minutes of slow cooking. Onions need time to break down, release their water, and gradually convert their starches to sugars through Maillard browning. Rushing this step with high heat just burns them; patience produces the deep, jammy sweetness that defines proper caramelization.

The deep finger dimples in the dough are not just for looks. They serve a structural purpose: catching pools of olive oil, holding the onion topping in place, and creating the signature uneven, rustic surface that distinguishes focaccia from regular pizza dough. Press firmly, almost to the bottom of the dough.

Letting the dough rise after shaping (not just relying on the bread machine’s rise) is the step that gives focaccia its characteristic puffy texture. The 30-minute rise on the cookie sheet allows the dough to relax and develop flavor before the topping goes on.

Pro Tips

• Use bread flour instead of all-purpose for chewier texture. The higher protein produces a more characteristic focaccia crumb.
• Brush the dough with olive oil before dimpling for the glossy, golden surface.
• Don’t skimp on caramelizing time. Brown onions are sweet; underdone onions are sharp.
• Cool 5 minutes before slicing; hot focaccia tears.

Variations

• Substitute fresh herbs like rosemary or thyme for additional aromatic interest.
• Top with cherry tomato halves, olives, or roasted bell peppers alongside the onions.
• Sprinkle flaky sea salt on top before baking for textural contrast.
• Use a mix of cheeses: gruyere, fontina, or aged provolone for different flavor profiles.
