Pollo in potacchio is a traditional poultry dish originating from the region of Marche. The dish consists of chicken with a tomato and rosemary sauce, and the list of ingredients includes a whole chicken that's cut into pieces, olive oil, butter, lemon, white wine, onions, garlic, and seasonings.

The potacchio sauce is typically added to chicken or rabbit dishes for a final touch, and it consists of onions or shallots, rosemary, lemon rind, dried chili peppers, olive oil, and tomatoes. The chicken is rubbed with lemon, fried in olive oil and butter, then cooked with white wine, onions, and garlic.

The potacchio sauce is added to the sauté pan with the chicken, and the combination is cooked until the chicken takes on the flavor of the sauce. Once done, the dish is served hot with the pan juices drizzled over it.
