Slow Cooked leg of lamb, how to cook so it is soft and tender?

This way of cooking a leg of lamb is my favourite, you just can't go wrong! No checking temperature of meat and worrying about over/undercooking.

It will be so soft and tender that you will not need a knife to carve, just a couple of forks to pull the tender meat off the bone.

The trick is to add liquid (stock) into the the tray and keep the lamb covered with foil throughout the majority of cooking to help retain moisture & stop the leg of lamb from drying out.

Should I marinade/glaze a leg of lamb?

You should not need any more than olive oil, pepper and salt for the first part of cooking, you can add any extra marinade or glaze when the leg of lamb is uncovered for the final 45 minutes of cooking.

We added this delicious Real Ale Chutney, by The Cherry Tree (check them out) to give a fantastic glaze, it tastes so amazing, you won't need any condiments with these amazing flavours coming through.
