Slow-cooked Osso Buco is a flavour-packed, nourishing family-friendly dish, made with simple low-cost ingredients in just one pan. The meat is cooked with vegetables in a tomato-based sauce until fall-apart tender, then topped with a fresh parsley gremolata.
To make the gremolata, combine the parsley, lemon zest, garlic, salt and pepper in a small bowl and set aside.
For the osso buco, sprinkle the flour and salt over the meat. Use your hands to coat evenly.
Heat the olive oil in a large, heavy-based frying pan over medium heat. Cook the osso buco for 5–8 minutes until browned all over. Transfer the meat to a plate and set aside.
To the same pan, add the carrot, celery, onion and garlic. Cook for 3–4 minutes or until softened.
Stir the tomato paste through for 1 minute. Add the passata, beef stock, black pepper, bay leaves and thyme.
Return the beef to the pan, bring it to the boil, place the lid on, then reduce the heat to the lowest setting.
Cook for 2½ hours. Add ½ cup (125 ml) water halfway through if the sauce starts to stick to the bottom of the pan. At the end of the cooking time, the beef should be tender enough to fall apart. If not, continue cooking in 20-minute intervals.
Serve with mashed potatoes and a side of steamed green beans and peas. Sprinkle generously with the gremolata.
