1 hour 30 minutes


Harissa lamb

  • 1/2 leg of lamb, butterflied (approx 1kg)
  • 8 garlic cloves, peeled
  • 2 tsp harissa
  • 2 tsp olive oil
  • 5 sprigs of fresh thyme
  • lemon, zested
  • salt
  • pepper

Mint and date chutney

  • 30g of fresh mint, leaves picked
  • 10g of parsley, leaves picked
  • 3 Medjool dates, pitted and roughly chopped
  • 1/4 tsp ground coriander
  • 1 tsp balsamic vinegar
  • 80ml of olive oil
  • 1 lemon, juiced
  • salt

Roast potato salad

  • 1kg new potatoes
  • 1 tin of chickpeas, drained
  • 150g of cherry tomatoes
  • 50g of black olives, sliced
  • 25g of capers
  • 2 tbsp of poppy seeds
  • 1 handful of parsley, chopped


Begin by marinating the lamb, do this the day before if possible. Score the outside of the leg. Using a small knife, make small cuts dotted around the lamb and poke 4 of the cloves of garlic into the holes (slice the cloves if they are large)
Finely grate the remaining garlic and mix the harissa with the olive oil, lemon zest, salt and pepper, then rub evenly over both sides of the lamb. Place the thyme on the underside and roll back up. Leave to marinate in the fridge for up to 2 days, but bring out of the fridge to come to room temperature before cooking
Preheat a ceramic barbecue to 180°C and set up your rotisserie attachment
Place the lamb leg on the rotisserie skewer, using the claws on each side to hold the lamb in place. Make sure you have no larger flaps hanging down or it won’t cook evenly. Cook on the rotisserie for 1 hour with the lid closed, and keep an eye on the temperature ensuring it stays between 160°C and 200°C
Par boil the new potatoes in salted water for 10–15 minutes then drain and lightly crush. Drizzle with olive oil and salt
Drain the chickpeas and place on a tray small enough to fit onto one side of the barbecue. Drizzle with olive oil and salt
To make the mint and date chutney, place all the ingredients in a blender and blitz. After a while, the oil will begin to emulsify with the dates, giving it a thick texture similar to mayonnaise. Taste and season with more lemon juice if needed and salt
Once the meat has cooked, remove the spit and leave the lamb to rest under tin foil for at least 20 minutes
Remove the rotisserie attachment and place both grills at the lower level. Place the potatoes directly onto the grills on one half and the tray of chickpeas on the other half. Close the lid at cook for around 30 minutes, turning the potatoes and shaking the tray of chickpeas every 10 minutes
With 10 minutes to go, the chickpeas should be crispy. Scrape them to one side of the tray and add the cherry tomatoes with a drizzle of oil
Remove the potatoes and place straight into the serving dish. Add the crispy chickpeas and tomatoes which should be hot and just starting to burst from their skins. Then sprinkle with the olives, capers, poppy seeds and parsley
Carve the lamb and serve up with the warm potato salad and mint and date sauce
