Harissa roast leg of lamb

A showstopper of a roast, and a wonderful change from the traditional Sunday joint. A fiery, smoky harissa rub of red chillies, garlic and warm spices works beautifully with the richness of the lamb, while a slow roast leaves the meat meltingly tender. Perfect for feeding a crowd, served with Molly's signature flatbreads to mop up all those gorgeous juices.

Ingredients

For the lamb

  • 1 leg of lamb, bone in (about 2kg)
  • Sea salt and black pepper

For the harissa rub

  • 4–5 red chillies, deseeded (adjust to taste)
  • 5 garlic cloves
  • 1 small bunch fresh coriander
  • 1 tsp cumin seeds
  • 1 tsp coriander seeds
  • 1 tsp fennel seeds
  • 1 tbsp soft brown sugar
  • Zest and juice of 1 lemon
  • 100ml olive oil
  • 1 tsp sea salt

To serve

  • Greek yoghurt mixed with a little chopped mint
  • Molly's signature flatbreads

Method

  1. Make the rub first. Gently toast the cumin, coriander and fennel seeds in a dry pan for a minute or two until fragrant, then tip into a blender.
  2. Add the chillies, garlic, fresh coriander, brown sugar, lemon zest and juice, olive oil and salt. Blend to a smooth paste.
  3. Sit the lamb in a large dish and cut several slits across the top with a sharp knife. Rub the harissa paste all over, working it into the slits. Cover and leave to marinate in the fridge, ideally overnight, or for at least a couple of hours.
  4. Take the lamb out of the fridge about an hour before cooking, so it comes up to room temperature. Heat the oven to 150°C (fan 130°C / gas 2).
  5. Place the lamb in a large roasting tin, cover tightly with foil, and roast slowly for about 2½ hours.
  6. Remove the foil and return the lamb to the oven, uncovered, for a further 30 minutes or so — until it is beautifully tender and lightly charred on top.
  7. Rest the lamb, loosely covered with foil, for 15 to 20 minutes before carving.
  8. Serve with a cooling minted yoghurt and Molly's signature flatbreads to soak up the juices.

Cook's notes

  • Adjust the heat: use fewer chillies, or remove all the seeds, for a milder rub — or leave some seeds in for more fire.
  • Make ahead: the harissa rub can be made up to two days ahead and kept in the fridge, and the lamb marinated overnight for the deepest flavour.
  • Add vegetables: red onions, peppers or aubergine roast beautifully in the spiced juices — add them to the tin when you remove the foil.

We can source a lovely leg of local lamb for you, and you'll find everything else for the rub — fresh chillies, garlic, lemons, spices and good olive oil — in the shop and online.
