Bisato in umido is a traditional Venetian dish made with eel cooked "in umido" (meaning "in a stew" or "braised"). In this preparation, the eel is first cut into pieces, then slowly braised in a rich sauce of carrots, celery, onions, garlic, and white wine, seasoned with bay leaves, parsley, and sometimes rosemary.

This slow cooking method allows the eel to become tender while absorbing the flavors of the aromatic sauce. The dish has a distinctive, slightly earthy flavor, as eel has naturally rich and oily meat. Bisato in umido is typically served with polenta, which complements the dish’s thick, flavorful sauce.
