About this dish

In the countryside of Emilia-Romagna, people used the residual heat of bread ovens to cook vegetables. Cipolle al forno is an onion contorno preserving that kitchen memory. In a region rich in meat, salumi and aged cheeses, sweet roasted onions have brought a gentle sweetness to the table.

Here even familiar vegetables such as onions are paired with balsamic vinegar and herbs, connecting them with local seasonings. Rather than a dish reserved for special occasions, they naturally accompany cold-season home cooking and oven-baked meals.

They are still served with roast meats and grilled dishes in homes and trattorias around Bologna. Within Emilia’s rich food culture, whole roasted onions provide a quiet sweetness that supports more flamboyant main dishes.
