  • DifficultyMedium
4 pre-cut lamb osso bucco (from local butcher)
Salt and freshly ground black pepper
4 tbsp olive oil
2 large carrots, peeled and chopped into 1cm squares
2 sticks of celery, roughly chopped into 1cm pieces
2 medium onions, roughly chopped into 1cm pieces
3 garlic gloves, crushed
60ml tomato puree
240ml red wine
1 litre lamb stock, recipe follows

For the lamb stock

900g lamb bones or 240ml lamb base
1 large carrot, roughly chopped into large pieces
1 large onion, roughly chopped into large pieces
1 stick of celery, roughly chopped into large pieces
2 L cold water
Salt and freshly ground black pepper
2 bay leaves, optional
2 tbsp fresh thyme leaves
For the roast lamb (lamb stock recipe below):

1) Preheat oven to 140°C / Gas mark 1.

2) Season lamb osso bucco liberally with salt and pepper and set aside on a plate. In a heavy-bottomed roasting pan over medium-high heat, heat olive oil on stove top. Carefully place the osso bucco in the hot roasting pan and sear all sides, until nicely browned. Once seared on all sides, remove from pan and set back onto plate. Using the same pot with the lamb drippings in the bottom, add carrots, celery, onions, and garlic. Saute for approximately ten minutes using a wooden spoon to scrape the lamb drippings off the bottom of the pan and to caramelize the vegetables. Once caramelized, add tomato paste, coat the vegetables with the paste, and brown slightly, about five minutes. Add the red wine to deglaze the pan, scraping the drippings off the bottom of pan using a wooden spoon. Reduce the wine by half and add the lamb stock and thyme. Season with salt and pepper.

3) Place the seared osso bucco back into the pan. Change to high heat and once the stock starts to boil, put roasting pan into the oven. Cook the osso bucco for about two hours until it is fork tender, almost falling off the bone. You will want to turn the osso bucco every half hour so that it cooks evenly and does not burn on the bottom.

4) When finished, take the lamb out of the sauce and set aside. In a blender, blend the sauce until the vegetables are pureed. Place about a 60ml of sauce into the bottom of each serving bowl, top with osso bucco and drizzle with a little more sauce. It is best served with roasted carrots, onions, and potatoes.

For the Lamb Stock:

1) Preheat oven to 200°C / gas mark 6.

2) In a large roasting pan, roast lamb bones in the oven until dark brown. On a sheet tray, roast carrots, celery, and onion in the oven until browned as well. Place the bones and vegetables in a 4-L stock pot. Add two litres of cold water, salt and pepper, and bay leaves, if desired. Bring to a boil over high heat and then turn down to a simmer over medium-low heat. Simmer for four to five hours to get the best results.

3) If using lamb base, roast vegetables as explained above. In a 4-L stock pot, add two litres water and whisk in lamb base. Add the roasted vegetables and bring to a boil. Turn down the heat to medium-low and simmer for approximately one hour.
