Ingredients
Method
Marinate the Lamb
- In a mixing bowl, stir together the minced garlic, lemon juice, lemon zest, olive oil, oregano, salt and pepper.
- Rub the marinade all over the lamb chunks, cover, and marinate in the fridge for at least 1 hour, or overnight for deeper flavor.
Assemble and Wrap
- Heat the oven to 160C / 320F.
- Line a 33 x 23 cm / 9 x 13-inch roasting dish with a large sheet of parchment paper, then a larger sheet of foil on top, leaving plenty of overhang on all sides.
- Scatter the potatoes, sliced onion, whole garlic cloves, bay leaves and cinnamon stick in the bottom of the dish.
- Set the marinated lamb chunks on top of the vegetables. Pour over any leftover marinade and the wine, then tuck the tomato quarters around the meat.
- Fold the parchment over the top first, then the foil, pressing the edges tightly closed so no steam can escape.
Roast
- Roast the sealed dish for 3.5 hours (210 minutes) at 160C / 320F, until an instant-read thermometer inserted into the thickest piece of lamb reads 95C / 203F and the meat feels loose around the bone.
- Carefully open the foil and parchment, watching for the burst of hot steam. Increase the oven to 200C / 390F.
- Roast uncovered for 20 to 25 minutes, until the lamb and potatoes turn golden at the edges.
Finish and Serve
- Let the dish rest for 10 minutes before serving, so the juices settle back into the meat.
- Spoon the pan juices over the lamb and potatoes when plating, and remove the bay leaves and cinnamon stick before serving.
Notes
- Marinate lamb at least 1 hour, overnight is better
- Seal the foil tightly, no gaps for steam to escape
- Check for internal temp of 95C/203F before opening the seal
- Cut potatoes into even quarters so they cook at the same rate as the lamb
