Ingredients
- 5 garlic cloves
- 1 lemon, juiced
- 6 tbsp ras el hanout spice mix (shop-bought or see tip below)
- 2 tbsp olive oil
- Small shoulder of lamb (about 2kg)
- 2 red onions, cut into large wedges
- 400g couscous
- 100g raisins
- 400g can chickpeas, drained
- Small bunch of parsley, chopped
- Small bunch of coriander, chopped
- 1 preserved lemon, finely chopped or the juice of ½ lemon
Instructions
- Step 1: Using a pestle and mortar or a mini chopper, mash or chop the garlic with a generous pinch of salt. Add the lemon juice, ras el hanout spice mix, and olive oil, then pound or chop to create a rough paste.
- Step 2: Use a small knife to make small incisions all over the lamb. Place the lamb in a large, shallow casserole dish or deep roasting tin. Rub the spice paste all over the lamb and into the incisions. Leave at room temperature for 1 hour or, better still, cover and chill overnight.
- Step 3: Preheat the oven to 160°C/140°C fan/gas mark 3. Scatter the onion wedges around the lamb. Cover the dish with a lid or tightly with foil and roast for 3 hours.
- Step 4: Remove the lamb from the oven and uncover. Stir the onions and baste the lamb in the juices. Increase the oven temperature to 180°C/160°C fan/gas mark 4 and continue roasting uncovered for 25–30 minutes until the lamb is browned.
- Step 5: Transfer the lamb and onions onto a board to rest. Bring a kettle of water to the boil. Stir the couscous and raisins into the dish so they are coated in the roasting juices.
- Step 6: Pour enough boiling water from the kettle to just cover the couscous. Cover the dish and leave for 5 minutes. Uncover and fluff up the couscous with a wooden spoon.
- Step 7: Stir through the chickpeas, chopped parsley, coriander, and preserved lemon or lemon juice. Season to taste. Serve the lamb, onions, and couscous together.
Tips & Variations
- If you can’t find ras el hanout, you can make a simple mix with ground cumin, coriander, cinnamon, ginger, turmeric, and paprika.
- For extra depth, marinate the lamb with the spice paste overnight in the refrigerator.
- Add toasted almonds or pine nuts to the couscous for a crunchy contrast.
- Serve with a dollop of Greek yogurt or labneh for creaminess.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. The couscous can be refreshed with a splash of water or lemon juice if it dries out.

FAQs
Can I use other cuts of lamb for this recipe?
Yes, but a shoulder cut works best for slow roasting as it becomes tender and juicy. You can also try a leg of lamb, though cooking times may vary.
What if I don’t have a preserved lemon?
You can substitute with the juice and some finely chopped zest of fresh lemon for a similar bright, tangy flavor.

Ingredients
Lamb and Marinade
- 5 garlic cloves
- 1 lemon, juiced
- 6 tbsp ras el hanout spice mix (shop-bought or homemade)
- 2 tbsp olive oil
- 1 small shoulder of lamb (about 2kg)
Vegetables and Couscous
- 2 red onions, cut into large wedges
- 400g couscous
- 100g raisins
- 400g can chickpeas, drained
Herbs and Garnishes
- Small bunch of parsley, chopped
- Small bunch of coriander, chopped
- 1 preserved lemon, finely chopped or ½ lemon juice
Instructions
- Prepare the marinade: Using a pestle and mortar or a mini chopper, mash or chop the garlic with a generous pinch of salt until pasty. Add the lemon juice, ras el hanout spice mix, and olive oil, then pound or chop to form a rough paste.
- Marinate the lamb: Use a small knife to make small incisions all over the lamb shoulder. Place the lamb in a large, shallow casserole dish or deep roasting tin. Rub the spice paste all over the lamb and into the incisions. Leave at room temperature for 1 hour or for best results, cover and refrigerate overnight for maximum flavor infusion.
- Preheat the oven: Heat your oven to 160°C (140°C fan)/Gas mark 3.
- Add onions and start roasting: Scatter the red onion wedges around the lamb in the casserole dish. Cover the dish with a lid or tightly with foil and place it in the oven to roast for 3 hours. This slow roasting will tenderize the lamb and develop deep flavors.
- Brown the lamb: Remove the dish from the oven and uncover it. Stir the onions to coat them in the lamb juices and baste the lamb as well. Increase the oven temperature to 180°C (160°C fan)/Gas mark 4 and continue roasting the lamb uncovered for an additional 25-30 minutes until the surface is browned and caramelized.
- Rest the lamb: Carefully lift the lamb and onions onto a board and allow the meat to rest while you prepare the couscous.
- Prepare the couscous: Stir the couscous and raisins into the lamb roasting juices in the casserole dish so they are well coated. Pour enough boiling water from a kettle to just cover the couscous. Cover the dish and let it stand for 5 minutes to allow the couscous to absorb the liquid.
- Fluff and finish couscous: Uncover the dish, fluff the couscous with a wooden spoon to separate the grains. Stir in the drained chickpeas, chopped parsley, chopped coriander, and preserved lemon or additional lemon juice. Season with salt and pepper to taste.
- Serve: Bring the rested lamb and onions back to the dish with the couscous and serve immediately for a warm, fragrant, and comforting meal.
