  1. Stir together the marinade ingredients and season with ½ tsp ground black pepper and 1½ tsp flaky salt. Slash the lamb several times on both sides, then massage the marinade all over it. Seal into a large food bag or non-metallic container and chill overnight (or at least for a few hrs). Let the lamb sit at room temperature for 1 hr before roasting.

  2. Heat oven to 220C/200C fan/gas 7. Put the lamb into a foil-lined roasting tin and roast for 20 mins. Turn the oven down to 190C/170C fan/gas 5 and roast for 1 hr 20 mins for meat that’s pink near the bone. Cover loosely with foil halfway through cooking or once the marinade has charred and the meat looks golden.

  3. Leave the lamb to rest for 20 mins before carving, then serve with lentil & tomato and cucumber salads (see related recipes).

It was delicious. Made it exactly as stated in the recipe. Wasn't sure what crushed chilli flakes are (had crushed chilli and chilli flakes so used half and half). Served with the suggested lentil and tomato salad and rice. There were no leftovers!

I had a leg of lamb which I didn't want to use for the usual boring roast, then found this recipe. Have never done this before but so easy, always get a bit worried when I try new things out on my friends. Served it with salad, salsa, tzatziki flat breads and afew other sides all made from scratch. All I can say was there was nothing left, 5 very satisfied guests. Exellent

Fantastic... we've just had this with a green salad, homemade cucumber and mint raita and french fries! What a great alternative to a Sunday roast, especially when the weather is good and you want to eat outside.

Hey, Esther from the food team here! We'd recommend leaving it out of the recipe or replacing with ground coriander, if you have any. Thanks for your question!
