  • 4 lamb leg steaks
  • 2 tbsp extra virgin olive oil
  • 2 tbsp lemon juice
  • 2 clove garlic crushed
  • 1 tsp chopped fresh thyme plus extra thyme to garnish
  • salt and freshly ground black pepper

Bean Mash

  • 1 tbsp extra virgin olive oil
  • 1 small onion chopped
  • 1 clove garlic crushed
  • 1 tsp chopped fresh thyme
  • 60 ml milk
  • 25 g butter
  • 2 x 400 g cans haricot (Navy) beans rinsed and drained


  • Mix together the oil, lemon juice, garlic and thyme in a shallow non-metallic dish. Season with salt and pepper  Add the lamb steaks and turn over so that they are covered in the marinade
  • Cover and allow the lamb to marinate for at least 1 hour or for up to 24 hours in the refrigerator.

To make the mash

  • Heat the oil for the mash in a saucepan and gently sauté the onion for 5 minutes until soft, add the garlic and cook for 1 minute. Add the butter and milk. Stir in the beans and heat gently stirring occasionally while you cook the lamb.
  • Remove the lamb from the marinade and cook under preheated grill or on a ridged griddle pan for 3–4 minutes each side. Transfer to a warm plate and allow to rest for a minute or two.
  • When the beans are piping hot, Season with salt and pepper. Remove from the heat and mash with a potato masher. Spoon onto serving plates and place the lamb on top, spooning any juices that have come from the meat during resting.
  • Garnish with a few thyme sprigs and serve.
