slow-cooked lamb

with garlic and rosemary

  • ½ cup (125ml) malt vinegar
  • ½ cup (90g) brown sugar 
  • 1 tablespoon olive oil 
  • sea salt and cracked black pepper 
  • 2kg lamb shoulder, bone in 
  • 18 single-clove garlic, unpeeled 
  • 6 sprigs rosemary 
  • 1½ cups (375ml) chicken stock
  1. Preheat oven to 180°C (350°F). Place the vinegar, ¼ cup (45g) sugar, oil, salt and pepper in a large bowl and stir to combine. Add the lamb and set aside to marinate for 20 minutes. 
  2. Place the lamb, skin-side up, in a large baking dish. Add the garlic, rosemary sprigs, marinade and stock. Sprinkle the lamb with the remaining sugar, cover with aluminium foil and roast for 2 hours and 30 minutes. Remove the foil and roast for a further 30 minutes or until the lamb is cooked to your liking. 
  3. Serve with the garlic. Serves 4–6

Tip: Single-clove garlic is a type of ‘elephant’ garlic. As its name suggests, it has one large clove, rather than a head of garlic that’s made up of a cluster of smaller cloves. Single-clove garlic looks similar to a small onion and is easy to peel. Find it at some supermarkets and grocery stores.

This recipe is so delicious. Thanks Donna Hay. I used boneless lamb roast. I baked a tray of mixed vegetables in a separate pan to go with it baby carrot, pumpkin, sweet potatoes, zucchini and potato. Lamb was so tasty and juicy. Yum yum

What a lovely recipe! I improvised and used normal garlic and planted them into the skin for extra caramelised garlic infusion as I am addicted!  The result was beautiful and went very well with Yorkshire puddings, roast potatoes and roast veggies! 10/10

This is the first time I have marinated my own lamb shoulder and cooked it in the oven.  It was beautiful and so very easy.  It was a great hit with everyone and I will certainly be making this one again. 10 out of 10 for me.

I dont usually enjoy food that I cook. Its often better when someone else cooks for you. but this was the best slow cooked lamb i have eaten let alone cooked. If I was served that in a restaurant i would be extremely happy,
