Ossobuco or osso buco (Italian: [ˌɔssoˈbuːko]; Milanese: òss bus [ˌɔz ˈbyːs]), also known as ossobuco alla milanese, is a specialty of Lombard cuisine of cross-cut veal shanks braised with vegetables, white wine, and broth. It is often garnished with gremolada and traditionally served with either risotto alla milanese or polenta, depending on the regional variation. The marrow from the hole in the bone (the buco in the osso) is a prized delicacy and the defining feature of the dish.
The two types of ossobuco are a modern version that has tomatoes and the original version which does not. The older version, ossobuco in bianco, is flavored with cinnamon, bay leaf, and gremolada. The modern and more popular recipe includes tomatoes, carrots, celery, and onions; gremolada is optional.
