This slow-roasted one-pot meal uses a boneless shoulder of lamb. Each cut is cooked in a jus infused with oregano, rosemary, garlic, onion, and lemon juice. One of our most flavoursome low calorie meals, this dish works out at just 415 calories per serving.


  • 500g (1lb) boneless shoulder of lamb, trimmed of fat, cut into 4 pieces
  • 2 tsp Season-All (we used Schwartz)
  • Salt and freshly ground black pepper
  • 1 tbs dried oregano
  • 2 tbs fresh rosemary leaves, stripped from the stalk
  • 2 red onions, peeled and each cut into 8 wedges
  • 6 cloves garlic, peeled
  • 1kg (2¼lb) potatoes, peeled and cut into 7.5cm (3in) chunks
  • 1 red pepper, deseeded and cut into 8 wedges
  • Juice of 2 lemons
  • You will also need a 3 litre (5 pint) casserole dish




  1. Set the oven to Gas Mark 5 or 190°C. Put the meat into the casserole dish and sprinkle over the Season-All, seasoning, oregano and rosemary leaves.
  2. Add the red onions, garlic, potatoes, pepper, lemon juice and 150ml (¼ pint) water. Cover with a well-fitting lid. Cook for 3 hrs until the meat is really tender.
