Slow Roast Ras el Hanout Lamb & Couscous Recipe
Introduction
This slow roast ras el hanout lamb with couscous is a flavorful and aromatic dish perfect for a comforting meal. The tender lamb infused with Moroccan spices pairs beautifully with a fragrant couscous studded with chickpeas, raisins, and fresh herbs.

Ingredients
- 5 garlic cloves
- 1 lemon, juiced
- 6 tbsp ras el hanout spice mix (shop-bought or homemade)
- 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 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 a rough paste.
- Step 2: Use a small knife to make incisions all over the lamb. Place the lamb in a large, shallow casserole dish or deep roasting tin, then rub the spice paste all over the lamb and into the cuts. Leave at room temperature for 1 hour, or cover and chill overnight for deeper flavor.
- Step 3: Preheat the oven to 160°C (140°C fan)/gas mark 3. Scatter the onion wedges around the lamb, then cover the dish with a lid or foil and roast for 3 hours.
- Step 4: Remove the dish 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 roast uncovered for another 25–30 minutes until the lamb is browned.
- Step 5: Transfer the lamb and onions to a board to rest. Stir the couscous and raisins into the roasting juices in the dish. Pour over enough boiling water to just cover the couscous, then cover and leave for 5 minutes.
- Step 6: Uncover and fluff the couscous with a wooden spoon. Stir in the chickpeas, chopped parsley and coriander, and preserved lemon or lemon juice. Season to taste.
- Step 7: Serve the lamb, onions, and couscous together, spooning the fragrant juices over the top.
Tips & Variations
- For a homemade ras el hanout, combine spices like cinnamon, cumin, coriander, turmeric, paprika, and ginger.
- If preserved lemon isn’t available, extra lemon juice adds a fresh zing to the couscous.
- Use bone-in lamb shoulder for extra flavor and juiciness.
- Raisins can be swapped for dried apricots or chopped dates for a different sweetness.
Storage
Store leftover lamb and couscous in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. The lamb may dry out if overheated, so adding a splash of water or broth while reheating helps keep it moist.

- 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
- Prepare the spice paste: Using a pestle and mortar or 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 form a rough paste.
- Marinate the lamb: Use a small knife to make small incisions all over the lamb. Place the lamb in a large casserole dish or roasting tin, then rub the spice paste all over and into the cuts. Leave at room temperature for 1 hour or cover and chill overnight for deeper flavor.
- Roast the lamb (part 1): 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 foil and slow roast in the oven for 3 hours to tenderize the meat.
- Roast the lamb (part 2): Remove the dish from the oven and uncover. Stir the onions and baste the lamb with the juices. Increase the oven temperature to 180°C (160°C fan)/gas mark 4 and roast uncovered for another 25-30 minutes until the lamb is browned and beautifully caramelized.
- Prepare the couscous: Transfer the lamb and onions to a board to rest. Stir the couscous and raisins into the roasting juices in the lamb dish. Pour boiling water over the couscous to just cover it, cover the dish and let it stand for 5 minutes.
- Finish the couscous: Uncover and fluff the couscous with a wooden spoon. Stir through the drained chickpeas, chopped parsley, coriander, and preserved lemon or lemon juice. Season to taste.
- Serve: Bring the rested lamb, onions, and the couscous dish to the table and serve warm for a hearty and flavorful meal.
Notes
- For best flavor, marinate the lamb overnight in the fridge.
- If you don’t have preserved lemon, fresh lemon juice works well but adds less depth.
- Ras el hanout is a Moroccan spice blend. If unavailable, a combination of ground cumin, coriander, cinnamon, ginger, turmeric, and paprika can be used as a substitute.
- Resting the lamb after roasting helps retain its juices and tenderness.
- You can prepare the couscous and mix-ins while the lamb rests to save time.
- Prep Time: 15 minutes plus 1 hour marinating (overnight optional)
