Last year I was lucky enough to be invited on a trip to Wales with PGI Welsh Lamb to see firsthand the landscape on which Welsh Lamb is nurtured, and the care and skill that goes into its production. Welsh Lamb has been recognised for its high quality, traceability and unique nature. It is farmed using traditional practices and methods on the rolling green hills, and beautiful salt-marshes of Wales. The main season for Welsh Lamb runs from August to November each year.


I love an easy recipe, and this one is so simple, with delicious results! You just cook everything in one, deep baking tray, you can just pop it in the oven and forget about it while it slow roasts and absorbs all of the delicious flavours.

I have used a half-leg of Welsh Lamb for my recipe, as it’s the perfect size to feed my family of 4, and leave some leftovers. You might not think to slow-roast a lamb leg, as it is often cooked for a much shorter time and then carved. I love the slow-roasting method as it takes any stress out of getting the leg cooked just right, as after a slow-roast it will be fall-apart tender, and will just shred straight from the bone. It’s a great way to maximise the use of all the meat, and also utterly delicious.

Only a really simple selection of ingredients are needed for this meal.

One half-leg of Welsh Lamb

  • 2 tins chickpeas
  • 2 onions
  • 2 tins chopped tomatoes
  • 20 Chantenay carrots
  • 1 lemon
  • 4 cloves garlic
  • 1 tbsp dried mint
  • 1 tbsp dried oregano
  • salt and pepper

This recipe is so simple to put together, you simply mix the onion, carrots, chickpeas, tomatoes and dried mint in a deep baking tray, place the half-leg of lamb (dotted with garlic cloves) on top, sprinkle over the oregano and salt and pepper, spry with spray oil, place the lemon slices on top then cover with foil and roast for 4 hours and 30 minutes! Just remove the foil for the last half an hour to get some nice colour into the lamb and caramelisation on the vegetables. When the lamb comes out of the oven it will be so tender that it will easily pull apart with 2 forks.
