Capesante gratinate is a classic Italian appetizer featuring scallops baked with a flavorful breadcrumb topping. This dish is particularly popular during festive occasions and special gatherings. The preparation involves placing fresh scallops in their shells, topping them with a mixture of butter, onion, and parsley, then sprinkling everything with breadcrumbs. The assembled scallops are then baked until the topping turns golden and crisp, enhancing the delicate flavor of the scallops.
