How to cook the Best Slow Cooked Leg of Lamb! Slow roasted at a low temperature, in the oven for 5 hours, so tender it falls off the bone. Real Ale Chutney added as a marinade for the last 45 minutes of cooking for a tasty sticky glaze. What’s more, you can use the stock, vegetables and juices leftover from the lamb, to make your own delicious gravy. Perfect Sunday Roast dinner to enjoy with the family.
See below our step by step slide show of how we make our Slow cooked leg of lamb, full recipe and instructions can be found on the card below.
We used a 1.8 kg leg of lamb for this recipe, however the same time will apply up until 2.2kg. I will include different weights and times in the recipe card below.
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.
How do you make lamb gravy from scratch?
This recipe not only makes a tender slow-cooked leg of lamb but also gives you the base sauce for your lamb gravy! All you need is a sieve, flour and pepper!

I love lamb! The meat has such a sweet taste. I’ve only had them grilled. The glaze is such a great suggestion. It would really enhance it.
Fantastic tender lamb, so much better slow cooked like this then how I usually do (to packet instructions) I love the use of chutney for extra flavour, tastes fab.
Oh my goodness this lamb looks so amazing! There is nothing better than fork tender flavorful lamb. I love the golden brown crust and the gravy looks wonderful!
Oh my! THis leg of lamb looks amazing! I so want a slice of it right now! Beautifully cooked and I absolutely love the ingredients used, the chutney in particular. Can’t wait o try this.
