A Rustic Italian Classic from Nonna’s Kitchen

Simple, comforting, and full of authentic Mediterranean flavors — Nonna’s Italian Baked Onions are a humble dish transformed into something special.

Slowly baked with tomatoes, garlic, parsley, and a generous sprinkle of Grana Padano, these onions become tender, sweet, and irresistibly savory.

Perfect as a side dish, light main course, or part of a traditional Italian family meal.

Ingredients (Serves 5)

• Extra virgin olive oil to taste

3. Sprinkle with cheese
   Generously cover the onions with grated Grana Padano cheese.

4. Add moisture
   Pour 2 cups of water into the baking dish to help the onions soften and cook evenly.
