Meltingly Tender 8-Hour Moroccan-Spiced Lamb Shoulder
The lamb emerges meltingly tender, surrounded by sweet, gooey onions and rich, spiced cooking juices. Serve it with warm focaccia and my cucumber yoghurt with fresh pomegranate for a genuinely ethereal experience.
Ingredients
For the lamb
1.5–2 kg bone-in lamb shoulder
2 large onions, roughly cut into 3 cm pieces
5–6 garlic cloves, thinly sliced into slivers
2 sprigs fresh rosemary
For the marinade
Follow my Sticky Moroccan Spiced Marinade recipe
Equipment
A large chopping board or washable work surface
A sharp knife
Heavy-duty aluminium foil
A large roasting tray or baking dish
An additional tray to catch any escaping juices
Method
1. Take the chill off the lamb
Remove the lamb shoulder from the refrigerator approximately 30–45 minutes before preparing it.
Unwrap it and pat the entire surface thoroughly dry with paper towel. A dry surface helps the marinade cling to the lamb.
2. Make the marinade
Follow the instructions in my Stick Moroccan Spiced Marinade recipe
3. Prepare the aromatics
Roughly chop the onions into approximately 3 cm pieces and set them aside.
Slice the garlic cloves lengthways into thin slivers. Strip the rosemary leaves from the sprigs, leaving some in small clusters.
4. Completely cover the lamb
Place the lamb shoulder on a large chopping board or another work surface that you are comfortable getting messy.
Generously massage the marinade over the entire shoulder, working it into every fold and crevice. The lamb should be comprehensively smothered.
5. Add the garlic and rosemary
Using a sharp knife, make small incisions approximately 1 cm deep across the surface of the lamb, spacing them roughly 1.5 cm apart.
Push a sliver of garlic and a few rosemary leaves into each incision.
Yes, this part is tedious. I promise the flavour is worth every single shoving effort.
6. Wrap the lamb
Preheat the oven to 115°C.
Lay out a long sheet of heavy-duty foil—large enough to wrap around the entire lamb shoulder with plenty of extra foil at each end.
Place a layer of chopped onion toward one end of the foil, then sit the lamb shoulder on top. Arrange the remaining onion over and around the lamb. It does not need to look perfect; it simply needs to make its way inside the parcel.
Wrap the foil firmly around the lamb, folding the seams tightly closed. Repeat with another four or five large sheets of foil until the shoulder is enclosed in a snug, secure parcel with no visible gaps.
The goal is to trap every bit of steam, flavour and precious lamb juice inside.
7. Slow-roast
Place the parcel in a large roasting tray or baking dish.
Slow-roast the lamb for 8 hours.
Do not unwrap during this time. Leave it be.
8. Rest the lamb
Carefully transfer the unopened parcel to a deep serving dish.
Leave it wrapped and allow it to rest for 45–60 minutes. This gives the meat time to relax while the juices settle back through the lamb.
9. Unwrap and serve
Carefully cut open the foil, watching for the hot steam and juices inside. Remove the foil without losing the onions or sauce beneath the lamb.
The meat should be extraordinarily tender and pull apart with almost no effort. The onions will have softened into the rich, fragrant cooking juices, creating a sauce that requires very little intervention.
You are welcome.
To Serve
Serve the lamb with freshly baked focaccia for an ethereal experience.
I also pair it with a light and creamy cucumber yoghurt with fresh pomegranate. Its freshness and acidity cut beautifully through the richness of the lamb and bring the entire plate together.
Suggested timeline for 6pm dinner
8:00 am: Remove the lamb from the fridge.
8:10–8:45 am: Prepare the marinade, onions, garlic and rosemary; coat and stud the lamb.
8:30 am: Preheat the oven to 115°C.
8:45–9:00 am: Assemble and tightly wrap the lamb parcel.
9:00 am: Place it in the oven.
5:00 pm: Remove the parcel after eight hours.
5:00–5:50 pm: Rest it, still completely wrapped.
5:50 pm: Carefully unwrap, arrange in its serving dish and spoon over the onions and juices.
6:00 pm: Serve and accept compliments.
For a calmer morning, prepare and wrap the lamb the night before, refrigerate it, then remove it around 8:00 am and place it in the oven at 9:00 am. Keep the raw lamb refrigerated overnight; don’t leave it on the bench.
Sofia’s Notes
Leftover slow-cooked lamb becomes my family’s all time favourite lamb pie. Buttery shortcrust pastry filled with rich, tender lamb and finished with a creamy, cheesy potato top.
To completely change the flavour profile, use the same wrapping and slow-roasting method but swap the Moroccan spices for a marinade of fresh oregano, mint, garlic, lemon zest, honey and olive oil. It is brighter, fresher and lovely in spring or summer.
Whichever variation you choose, serve it with cool cucumber yoghurt. The freshness and acidity cut through the richness of the lamb perfectly.
