Lamb kleftiko is one of the great slow-cooked dishes of Greek cuisine - fall-apart tender lamb, fragrant with garlic, lemon, oregano, and cinnamon, sealed in a parcel and slow-roasted until the meat is so soft it barely needs a knife. The name comes from the Greek word for thief (kleftis), referring to the bandits who would bury and slow-cook their stolen meat underground to avoid detection. Today the parcel method is recreated in the oven, trapping all the steam and flavour inside for an extraordinarily succulent result.
What makes kleftiko special is its simplicity - a handful of everyday ingredients, a good piece of lamb, and time in the oven does all the work. Lamb shoulder is the traditional and ideal cut, widely available at all major UK supermarkets, and it becomes beautifully rich and gelatinous after hours of slow roasting.
This is a brilliant recipe for a relaxed dinner party or Sunday roast - virtually all the effort happens before the oven does the rest. Serve with roasted potatoes cooked in the same parcel, a simple Greek salad, and warm pitta to mop up the incredible cooking juices.
Ingredients
For the marinade
- 4 tbsp Olive Oil
- 3 tbsp Lemon Juice
- 4 Garlic Cloves , minced
- 1.5 tsp Dried Oregano
- 1 tsp Ground Cinnamon
- 0.5 tsp Ground Cumin
- 1 tsp Salt
- 0.5 tsp Black Pepper
For the parcel
- 600 g Bone-in Lamb Shoulder Chops or Lamb Shoulder Pieces
- 400 g Potatoes (Maris Piper or similar) , peeled and cut into large chunks
- 1 Large Onion , cut into wedges
- 2 Large Tomatoes , roughly chopped
- 1 Red Pepper , deseeded and cut into chunks
- 2 Bay Leaves
- 2 Sprigs of Fresh Rosemary
- 100 ml White Wine , (or chicken stock if preferred)
- 100 g Feta Cheese , crumbled (optional but traditional) (optional)
Method
-
In a large bowl, whisk together all the marinade ingredients. Add the lamb pieces and turn to coat thoroughly. Cover and refrigerate for at least 2 hours, or ideally overnight - the longer it marinates, the deeper the flavour.
Tip: If you're short on time, even 30 mins of marinating makes a difference. But overnight genuinely transforms the dish. -
Preheat your oven to 160°C fan / 180°C conventional / Gas Mark 4.
-
Tear off two large sheets of baking paper and two large sheets of foil - enough to generously wrap everything. Layer the baking paper on top of the foil (this prevents the acidic lemon juice from reacting with the foil directly). Place half the potatoes, onion, tomatoes, and red pepper in the centre of each parcel, then lay the marinated lamb on top. Scatter over the bay leaves, rosemary, and pour half the wine or stock over each parcel. If using feta, crumble it over now.
-
Bring the sides of the baking paper up around the filling, then wrap the foil tightly over the top to create a completely sealed parcel with no gaps for steam to escape. Place both parcels in a roasting tin.
Tip: A well-sealed parcel is the key to kleftiko. Any gaps will let the steam escape and the lamb won't braise properly - take your time to seal it thoroughly. -
Roast for 3 hours, then carefully open the top of each parcel (watch out for the steam) and fold back the paper and foil to expose the lamb and potatoes. Increase the oven temperature to 200°C fan / 220°C conventional / Gas Mark 7 and return to the oven for a further 25–30 mins until the lamb is golden and caramelised on top and the potatoes are tender.
-
Rest for 10 mins before serving directly from the parcel. Spoon over the cooking juices and serve with a Greek salad and warm pitta or flatbread.
Alternatives & Variations
Use lean lamb leg steaks instead of shoulder - significantly lower in fat, though the result won't be quite as rich and falling-apart tender; reduce cooking time to around 2 hrs
Reduce the olive oil in the marinade to 2 tbsp - it still coats the lamb well and cuts the fat noticeably
Skip the feta - it adds creaminess and saltiness but also saturated fat; the dish is still deeply flavourful without it
Swap the white wine for chicken or vegetable stock - removes the alcohol and saves a small number of calories
This recipe is naturally gluten free. All ingredients - lamb, vegetables, olive oil, lemon, herbs, and spices - contain no gluten. If using stock instead of wine, check the label to confirm it is gluten free, as some stock cubes contain wheat derivatives. Check the feta packaging too if you have a severe intolerance.
FAQs
Around 3 hrs 50 mins total, including 20 mins of prep and 3 hrs 30 mins in the oven. Factor in at least 2 hours of marinating time beforehand - or ideally overnight. It's a long cook but almost entirely hands-off.
Rated Easy. Despite the impressive results, there's very little technical skill involved - the main tasks are making a marinade, chopping vegetables, and wrapping a parcel. The oven does the rest. It's genuinely one of those dishes where the effort-to-reward ratio is exceptional.
Yes - lamb kleftiko freezes very well. Cool completely, then transfer the lamb and vegetables (without the bay leaves and rosemary sprigs) to an airtight container and freeze for up to 3 months. Defrost overnight in the fridge and reheat covered in the oven at 170°C fan for 25–30 mins until piping hot throughout.
It's ideal for making ahead. The lamb can be marinated up to 24 hours in advance. You can also assemble the sealed parcels the morning of and keep them in the fridge until ready to bake. Cooked kleftiko reheats beautifully and some would argue it tastes even better the next day.
The potatoes and vegetables cook inside the parcel, so it's a fairly complete meal on its own. It pairs brilliantly with a simple Greek salad of tomatoes, cucumber, red onion, olives, and feta, plus warm pitta or homemade Greek flatbread to mop up the cooking juices. A dollop of tzatziki on the side is never a bad idea.
Bone-in lamb shoulder is the most authentic and flavourful cut - the bones add depth to the cooking juices and the high fat content of the shoulder makes the meat incredibly tender after slow roasting. Lamb shoulder chops work brilliantly and are easy to find at any major UK supermarket. Bone-in leg of lamb can also be used for a leaner result.
