Osso Buco is a traditional Italian dish made from VEAL shanks. The meat used in the dish is usually VEAL, which is a young calf that has not yet been weaned. The name Osso Buco comes from the Italian phrase for 'bone with a hole, ' referring to the marrow-filled center of the VEAL shank. The dish is usually served with a side of risotto or polenta and is often garnished with gremolata, a mixture of parsley, garlic, and lemon zest.
