Tuna Ossobuco with Mashed Potatoes and Purple Cabbage

**Tuna Ossobuco with Mashed Potatoes and Purple Cabbage**

Tuna Ossobuco is a contemporary reinterpretation of the classic Milanese veal ossobuco, substituting the traditional meat with a thick cross-cut section of tuna loin, complete with a central bone. This dish exemplifies the modern Italian culinary movement that reimagines regional traditions through the lens of seafood.

The dish originated in the coastal Marche region of Italy, where chef Moreno Cedroni of Madonnina del Pescatore in Senigallia pioneered the concept. As noted on the culinary platform *Cosa mangiamo oggi?*, Cedroni’s version transforms the hearty land-based braise into a delicate, oceanic experience. The key ingredients include a thick tuna steak cut across the spine, slow-cooked to maintain its moisture and flaky texture, served alongside creamy mashed potatoes and braised purple cabbage for color and acidity.

A great version of Tuna Ossobuco is distinguished by the quality of the tuna—ideally from sustainable sources like bluefin or yellowfin—and the precision of its cooking. The fish should remain tender and not overcooked, with the bone adding depth to the sauce. The mashed potatoes must be velvety and rich, often enriched with butter and cream, while the purple cabbage provides a sweet-and-sour counterpoint, typically braised with red wine or balsamic vinegar.

Regional variations exist along the Italian coast, with some chefs incorporating citrus or capers to brighten the dish, or substituting the cabbage with sautéed greens. In Senigallia, Cedroni’s version remains the benchmark, celebrated for its balance of land and sea.
