Spring lamb is a delicious and easily cooked meat. We at 50connect are far from being culinary kings and queens, so roast lamb as an easy Sunday lunch makes perfect sense and because you don’t have to slave over the stove while it cooks – you’ll have plenty of opportunity to put your feet up and enjoy the long weekend.

Roast lamb with mint sauce

Choose the traditional bone-in leg or a boneless rolled joint – it does work with a rack but you’ll need to adjust your timings.  For a slightly sweeter taste, opt for shoulder of lamb.

Feeds: 4-6

Time to prepare: 15 minutes

Time to cook: Medium: 25 minutes per 450g (1lb) plus 25 minutes, Well done: 30 minutes per 450g (1lb) plus 30 minutes

Oven temperature: Gas mark 4-5, 180-190°C, 350-375°F


  • 1.3kg (3lb) lean lamb leg, shoulder or half shoulder joint
  • Salt and pepper
  • Zest of 1 lemon
  • 2 large garlic cloves, peeled and sliced lengthways
  • 2 large sprigs fresh rosemary leaves
  • 15ml (1tbsp) olive oil
  • 45ml (3tbsp) lemon marmalade, melted


15ml (1tbsp) plain flour
600ml (1pint) good, hot lamb stock, homemade, if preferred

Mint sauce

(makes 150ml):

  • 1 x 30g pack fresh mint leaves, stalks removed
  • 60ml (4tbsp) light muscovado sugar
  • 150ml (¼pint) boiling water
  • 150ml (¼pint) white wine vinegar


  1. Place the joint on a chopping board and make several slits on both sides. Season. In a small bowl mix together the lemon zest, garlic, rosemary leaves and oil.
  2. Stuff the mixture into the slits, brush with any of the remaining mixture, place the joint on a metal rack in a large non-stick roasting tin and cover and roast for the preferred, calculated cooking time. 40 minutes before the end of the cooking time remove the foil.
  3. 10-15 minutes before the end of the cooking time glaze the joint with the lemon marmalade.
  4. To prepare the mint sauce: pound together the mint leaves and sugar in a mortar and pestle to a rough paste.  Alternately place in a food processor or blender and blend to a paste.  Add the boiling water and leave to infuse for 5-10 minutes.
  5. When the mixture is almost cold, stir in the vinegar and transfer to a serving bowl.  Leave the sauce to stand for 1-2 minutes before serving.
  6. Remove your joint from the oven and allow to rest for 10minutes.
  7. Sit down with your family and enjoy a perfect Easter roast. Bon appetit!
