With lemony garlic marinade and potatoes that soak up every delicious drop of lamb juice, it’s a total showstopper. I made this for a weekend dinner, and it completely stole the spotlight.

Ingredients Needed
For the Lamb and Marinade:
- 2kg leg of lamb
- 6 garlic cloves
- 3 tbsp roughly chopped oregano
- 1 tbsp roughly chopped rosemary
- Zest of 1 lemon and juice of 2 lemons
- ½ tsp ground cinnamon
- 2 tbsp olive oil
- Salt and black pepper, to taste
For the Potatoes:
- 1kg Desiree potatoes (or Yukon Gold), halved or quartered
- 1 tbsp olive oil
- 5 bay leaves
How To Make Jamie Oliver Lamb Kleftiko
Prepare the Marinade:
Start by crushing the garlic cloves with a teaspoon of salt using a pestle and mortar until it becomes a rough paste. Add the oregano, rosemary, lemon zest, cinnamon, and a good amount of freshly cracked black pepper. Crush a bit more, then stir in 2 tablespoons of olive oil to bring it all together. This will become your fragrant marinade.
Marinate the Lamb:
Use a sharp knife to poke holes all over the lamb—this helps the marinade really get in there. Rub the paste into the meat, pressing it deep into the holes. Then place the lamb in a large food-safe bag, pour over the lemon juice, seal it, and refrigerate overnight. Trust me, the longer it sits, the better the flavor.
Prep for Roasting:
Take the lamb out of the fridge an hour before cooking so it comes to room temperature. Meanwhile, preheat your oven to 160°C/140°C fan/gas mark 3.
Build the Roasting Parcel:
Lay down two long pieces of parchment on top of two long pieces of foil in a criss-cross shape. Place the potatoes in the center, drizzle with the remaining olive oil, season, and toss to coat. Pour over any leftover marinade and scatter the bay leaves on top.
Roast the Lamb:
Place the lamb directly over the potatoes, then wrap everything tightly in the parchment and foil. Pop it in a roasting tin and into the oven it goes for 4½ hours. Low and slow is the name of the game.
Crisp Things Up:
After roasting, take the parcel out and crank the oven to 220°C/200°C fan/gas mark 7. Unwrap the lamb and return it to the oven for 20 minutes to develop a gorgeous golden crust. Once browned, remove it, re-wrap in foil, and let it rest.
Final Potato Perfection:
Turn the potatoes in the juices, then pop them back into the oven for another 30 minutes until they’re golden and crisp. Don’t forget to season them right after they come out.
Serve:
Slice up the lamb, spoon over those incredible juices, and serve it all up with the roasted potatoes.
