In a large casserole dish, over high heat, add a splash of oil and fry the beef Osso Buco pieces (season first) until nice and browned (don't over-crowd them in the pan so maybe do in batches).Please them on a plate and set aside.
Turn the heat down and add the garlic, thyme and bay leaves then pour in the stock. Bring to a simmer, pop the lid on and into the oven on 160C for approx. 3.5 hrs or until the meat is tender.Remove the bones and using two forks, break up the tender meat.
Cook you gnocchi to the packet instructions and then add to the Osso Buco.Mix and then serve.
