Lamb shanks are good value and the slow cooking means the meat is very tender. A single shank will feed one person generously. For smaller children you might like to buy one between two. This is an easy dish to prepare but looks very impressive, great for entertaining!
Pre-heat the oven to 160°C/325°F/gas mark 3. Heat a film of olive oil in a roasting tin over a medium heat. Add the lamb shanks and brown or sear on all sides then remove to a dish. This will take around 10 minutes.
Add the onions and carrots to the roasting dish and stir until they begin to soften. Add the garlic and rosemary and stir for a couple more minutes.
Add the stock, tinned tomatoes and white wine. Season with salt and pepper and stir together. Place the lamb shanks in the sauce.
Cover the roasting tin tightly with foil and scrunch the edges so it is a good fit. Cook in the oven for 2 - 2 ½ hours until the meat is really tender.
