Italian Onion Flat Bread (Focaccia)

Italian onion focaccia is the rustic, snackable cousin of pizza, with origins in Ligurian baking on the northern Italian coast. This version finishes with a generous topping of buttery sautéed onions and a sprinkle of fresh rosemary, giving the soft, dimpled bread its signature savory aroma.

The scoring trick is what makes this look bakery-worthy. A shallow knife cut about an inch from the edge of the flattened dough creates a built-in border that puffs up around the topping during the bake, framing the onions like a flatbread pizza.

Pricking the center with a fork before topping is intentional. It keeps the middle from doming up under the heat and gives the onions a flat, even surface to settle into.

A double rise (first the dough, then the topped flatbread) is what gives focaccia its airy crumb. Skip the second rise and the bread will bake into a flat, denser disc. Patience pays off.

Pro Tips

• Use very warm water (about 110°F or 43°C) to wake up the yeast without killing it. Hotter is fatal; cooler is sluggish.
• Sauté the onions until just soft and translucent, not browned. They finish cooking in the oven on top of the bread.
• Brush the dough lightly with olive oil before adding the onions. This keeps the surface from going dry during baking.
• Serve warm, torn rather than sliced, alongside a bowl of olive oil for dipping.

Variations

• Swap onions for caramelized red onions and a few crumbles of feta for a Greek-leaning version.
• Add halved cherry tomatoes, sliced olives, or thin garlic slivers to the topping.
• Brush the finished bread with extra olive oil and flaky sea salt right out of the oven for a more traditional Ligurian finish.
