Slow-Roasted Harissa Lamb Shoulder with Pomegranate, Toasted Almonds and Herbed Yoghurt
There is a particular kind of cooking that is not about effort but about conviction. You decide the meal is going to be extraordinary. You make a handful of deliberate choices about flavour. And then you put it in the oven and let time do what no amount of technique can replicate.
This slow-roasted harissa lamb shoulder is that kind of cooking. The lamb goes in at a low temperature, covered tightly, and stays there for four to five hours while you do entirely whatever you please. What comes out is meat so tender it parts at the touch of a fork, juices that have concentrated into a deeply savoury sauce, and a kitchen that smells like somewhere remarkable. A final fifteen minutes uncovered caramelises the harissa crust into something dark and fragrant at the edges. Then you scatter the pomegranate seeds, which land like rubies on the surface, add the toasted almonds for crunch, pile on the fresh herbs, and bring the whole thing to the table in the tin it was cooked in, because a dish this confident needs no further presentation.
The herbed yoghurt alongside does what cooling elements always do alongside bold, spiced meat: it creates a balance that makes every mouthful more interesting than the last.
This is a meal for October evenings when the dark arrives early and the temperature has properly dropped. It is a meal for the table rather than the sofa, for people you want to feed properly, or for yourself alone on an evening when you have decided that you deserve something magnificent. Both are entirely valid reasons to make it.
Slow-Roasted Harissa Lamb Shoulder with Pomegranate, Toasted Almonds and Herbed Yoghurt
Prep Time: 15 minutes, plus marinating | Cooking Time: 4 hours 45 minutes | Total Time: 5 hours, plus marinating | Serves: 4 to 6
INGREDIENTS
• 2 kilograms bone-in lamb shoulder, approximately 2kg
• 3 tablespoons tablespoons rose harissa paste
• 3 tablespoons tablespoons extra virgin olive oil
• 4 garlic cloves, finely grated
• 1 teaspoons teaspoon ground cumin
• 1 teaspoons teaspoon ground coriander
• 0.5 teaspoons teaspoon ground cinnamon
• 1 fresh lemon, zested and juiced
• 1 pinch sea salt and freshly ground black pepper
• 200 milliliters lamb or chicken stock
• 1 large pomegranate, seeds only
• 50 grams flaked almonds, toasted in a dry pan until golden
• 200 grams full-fat Greek yoghurt
• 2 tablespoons tablespoons fresh mint leaves, roughly torn
• 2 tablespoons tablespoons fresh flat-leaf parsley, roughly chopped
• 1 tablespoons tablespoon fresh coriander leaves, roughly torn
• 0.5 garlic clove, finely grated, for the yoghurt
• 4 good quality shop-bought flatbreads, to serve
STEPS
1. Marinate the lamb: In a small bowl, combine 3 tablespoons tablespoons rose harissa paste, 3 tablespoons tablespoons extra virgin olive oil, 4 garlic cloves, finely grated, 1 teaspoons teaspoon ground cumin, 1 teaspoons teaspoon ground coriander, 0.5 teaspoons teaspoon ground cinnamon, the zest of 1 fresh lemon, zested and juiced, and a generous pinch of 1 pinch sea salt and freshly ground black pepper. Mix to a paste. Using a sharp knife, score the surface of 2 kilograms bone-in lamb shoulder, approximately 2kg deeply all over, making cuts approximately 2cm deep. This allows the marinade to penetrate the meat and gives the final crust somewhere to catch and caramelise. Rub the harissa paste all over the lamb, working it into the scored cuts. Cover and refrigerate for at least 60 minutes, or ideally overnight. Remove from the fridge 30 minutes before cooking.
2. Prepare for roasting: Heat your oven to 160°C, 140°C fan, gas mark 3. Place the marinated 2 kilograms bone-in lamb shoulder, approximately 2kg in a large, deep roasting tin. Pour 200 milliliters lamb or chicken stock and the juice of 1 fresh lemon, zested and juiced around the base of the lamb, not over it, to preserve the harissa crust. Cover the tin very tightly with a double layer of foil, pressing it firmly around the edges to create a good seal. The steam trapped inside is what keeps the lamb moist during the long cooking time.
3. Slow roast: Place the covered tin in the oven and roast for 240 minutes without opening the oven or lifting the foil. Resist the temptation to check. The lamb needs this uninterrupted time to break down properly. After 4 hours, remove the tin from the oven and carefully lift one corner of the foil, standing back from the steam. The lamb should already be pulling away from the bone.
4. Caramelise the crust: Increase the oven temperature to 200°C, 180°C fan, gas mark 6. Remove the foil entirely and return the lamb to the oven, uncovered, for a further 30 to 45 minutes until the surface is deeply caramelised, dark at the edges, and fragrant. Watch it during this final stage and cover loosely with foil if any part looks in danger of burning rather than caramelising. (40 minutes)
5. Make the herbed yoghurt: While the lamb finishes, make the herbed yoghurt. Combine 200 grams full-fat Greek yoghurt, 0.5 garlic clove, finely grated, for the yoghurt, half of 2 tablespoons tablespoons fresh mint leaves, roughly torn, and a pinch of 1 pinch sea salt and freshly ground black pepper in a small bowl. Stir well and taste for seasoning. It should be cool, creamy, and fragrant. Set aside.
6. Rest the lamb: Remove the lamb from the oven and leave to rest in the tin for 10 minutes. This allows the juices to redistribute through the meat before it is pulled apart. Do not skip the resting time.
7. Finish and serve: Scatter 1 large pomegranate, seeds only, 50 grams flaked almonds, toasted in a dry pan until golden, 2 tablespoons tablespoons fresh flat-leaf parsley, roughly chopped, 1 tablespoons tablespoon fresh coriander leaves, roughly torn, and the remaining 2 tablespoons tablespoons fresh mint leaves, roughly torn generously over the surface of the lamb. The pomegranate seeds should catch in the crevices of the pulled meat and the juices in the tin. Drizzle with a little extra olive oil and finish with a final grind of black pepper. Bring the tin directly to the table with the herbed yoghurt alongside and the warmed 4 good quality shop-bought flatbreads, to serve for tearing. Let everyone pull the lamb apart themselves.
**Hints & Tips**
**On the harissa.** Rose harissa is worth seeking out specifically. It has a deeper, more complex flavour than standard harissa, with a floral warmth that works beautifully with slow-cooked lamb. Belazu rose harissa is widely available in UK supermarkets and is excellent. If you can only find regular harissa, it works perfectly well. Start with two tablespoons and adjust to your heat preference.
**On marinating.** The longer the better. Overnight in the fridge produces a noticeably more flavoured result than a one-hour marinade, as the harissa and spices penetrate the scored flesh more deeply. If marinating overnight, bring the lamb to room temperature for at least 30 minutes before it goes into the oven.
**On the foil seal.** This is not optional. The tight foil seal traps the steam from the stock inside the tin, which is what keeps the lamb moist and falling-apart rather than drying out during the long cooking time. Press it firmly around the edges of the tin and check it has not lifted partway through if you open the oven for any other reason.
**On the pomegranate seeds.** To remove them cleanly without spraying juice everywhere, cut the pomegranate in half and hold each half cut-side down over a large bowl. Hit the skin firmly with a wooden spoon. The seeds will fall into the bowl and the pith will stay behind. Do this over the bowl rather than the lamb, as pomegranate juice stains dramatically and permanently.
**On the flatbreads.** Shop-bought flatbreads are entirely correct here and need no apology. Warm them in a dry frying pan for one minute per side, or wrap them in foil and place in the oven for the final ten minutes of cooking. Both methods produce a warm, slightly charred result that is far better than cold flatbreads straight from the packet.
**On the yoghurt.** Full-fat Greek yoghurt only. Low-fat yoghurt has neither the richness nor the stability to stand up against the harissa lamb. The yoghurt is not a garnish. It is a structural component of the dish, and it deserves to be treated accordingly.
**On serving.** Bring the roasting tin directly to the table and let people pull the lamb apart themselves using two forks. This communal, slightly informal style of serving suits the dish perfectly and removes any pressure on the cook to carve neatly, which is impossible with properly slow-roasted lamb in any case.
**On storing leftovers.** Leftover lamb keeps in an airtight container in the fridge for up to three days and is arguably even better the following day once the spices have had time to settle further. It is extraordinary cold in a flatbread with the remaining yoghurt, a handful of rocket, and a squeeze of lemon. The juices from the tin should be stored separately and used to reheat the meat gently on the hob with a splash of water.
**On making it ahead.** This recipe is ideal for making a day in advance. Cook it completely, allow it to cool, and store covered in the fridge. Reheat covered in foil at 160°C for 30 to 40 minutes, then uncover and blast at 200°C for 10 minutes to re-caramelise the outside. Scatter the fresh toppings immediately before serving.
