Here’s what you’ll need:


  1. 1 bulb of garlic, 3 cloves peeled and crushed, the others left whole
  2. a small bunch of fresh rosemary, half the leaves removed and coarsely chopped, half in sprigs
  3. zest of 1 lemon
  4. olive oil
  5. 2kg leg of lamb
  6. sea salt and freshly ground black pepper
  7. 1.5kg potatoes, peeled and cut in half
  8. 4 tablespoons chopped, fresh mint leaves
  9. 1 teaspoon sugar
  10. 2 pinches of salt
  11. 1 tablespoon hot water
  12. 3 tablespoons wine vinegar


  • Preheat the oven to 200ºC/400ºC/gas 6 and place a roasting dish for the potatoes on the bottom.
  • Mix the crushed garlic, chopped rosemary, lemon zest and olive oil together. Season the lamb with salt and pepper and rub the marinade into it. Place on the hot bars of the oven above the tray.
  • Boil the potatoes, simmer for 10 minutes and scuff the edges. Add the rosemary sprigs and whole garlic cloves, season with salt and pepper and drizzle over a good glug of olive oil. Tip the potatoes into the tray and place under the lamb to catch all the lovely juices.
  • To make the mint sauce, mix the chopped mint, sugar, salt, hot water and wine vinegar.
  • Cook the lamb for about an hour and 15 minutes if you want it pink, or an hour and a half if you want it more well done. Take it out of the oven and cover with tinfoil and leave for 15 minutes before serving. Carve and serve with the potatoes and mint sauce.

You could toss in some parsnips, carrots or any other root vegetable you prefer along with the potatoes to make it heartier. Enjoy!
