Quick Tip
If you’d like your leg of lamb to be a little crispy on top when you serve, with a mouthwatering mint glaze, simply finish it off in the oven for 20-30 minutes once it’s cooked.
You don’t have to do this – you can serve the lamb straight from the slow cooker and it will be meltingly tender. However, it won’t have much colour, so a quick blast in the oven gets you that extra texture if you have time.
It also means you can make a mint glaze that takes it to another level.
Slow Cooker Leg of Lamb Ingredients
- Lamb leg – Buy a lamb leg joint WITHOUT bone (otherwise it won’t fit into the slow cooker!) This is usually then rolled into a neat shape and held with string.
- Sea salt and freshly ground black pepper – Make sure you season generously.
- Garlic – Fresh or frozen is fine.
- Vegetables – White onions and carrots are used to add extra flavour.
- Lamb stock – Made from a cube is fine
- Cornflour (or corn starch if you’re in the USA) – Make a slurry with this to thicken the gravy at the end of cooking.
- Soy sauce – Use this to flavour the gravy. I use light soy sauce.
- Mint jelly – If you decide to finish of in the oven, smother this on the meat beforehand to get an amazing glaze before serving.
How to cook a leg of lamb in a slow cooker
1. Put the garlic, onions, carrots, lamb leg and stock into a slow cooker, then season. Cook according to the recipe below.
2. When cooked, put the meat in a tin, smother it with mint jelly and bake in the oven, as per the recipe below.
3. While the lamb is baking, get rid of the fatty layer from the cooking liquid. Remove a small amount of the liquid into a bowl and stir in the cornflour into it until it dissolves and you have a thick paste.
4. Add this back into the slow cooker pan, add the soy sauce and stir. Heat according to the recipe below. Serve with your cooked lamb.
Leftovers
In the fridge You can keep this recipe in the fridge for 3 days.
I often serve lamb leftovers with orzo pasta because it’s super quick to cook and soaks up the gravy beautifully. You could also use it in a curry.
Leftover lamb also freezes fine in the gravy for another day’s feasting. Defrost thoroughly before reheating in the microwave or oven.
For any surplus gravy, freeze it to save for another day’s delicious beef gravy. Store in freezer bags so you can keep them flat to save space.

Faqs
You can either put it on overnight and cook it on low for a little longer (it’s very difficult to overcook) OR use a timer plug like this one to start the slow cooker overnight. Genius!
No! I think you get a much better result with this dish by browning AFTER cooking, when a lot of the fat has already cooked off. The result is crunchy on top and soft underneath.
Serve it with some hearty sides such as Cauliflower Cheese, Roast Potatoes, Boulangere Potatoes or Colcannon, and some vegetables and maybe Yorkshire Puddings.

Slow Cooker Leg of Lamb {Easy Recipe}
Ingredients
- 2 kg Lamb leg (boneless, rolled), Approx. weight
- 3 Garlic cloves, Peeled and chopped or crushed
- 2 Large onions, Peeled and cut into chunks
- 3 Large carrots, Peeled and chopped into chunks
- 400 ml Hot lamb stock
- 3 tbsp Cornflour
- 100 g Mint jelly
- 2 tbsp Soy sauce
- Sea salt and freshly ground black pepper
Instructions
- Put the garlic, onions, carrots, lamb leg and stock into the slow cooker. Add salt and pepper.
- Cook on HIGH for 10 hours or LOW for 12 hours.
- When cooked, remove the meat to a tin, smother in the mint jelly and bake in the oven at 220℃ fan/240℃/Gas Mark 9 for about 20-30 minutes or until browned.
- Remove the carrots and onions and set aside.
Meanwhile, make the gravy:
- When the lamb is cooked, get rid of the fatty layer from the cooking liquid in the slow cooker. (I use my trusty Oxo Good Grips Gravy Separator for this job. You can do it manually instead by spooning off the layer of fat on top of the cooking liquid.)
- From the remaining juices, remove a small amount of the liquid from the pan (say, a tablespoon or two) into a mug or bowl and stir in the cornflour (or corn starch if you're in the US) into it until it dissolves. Add a small amount at first and stir in. Keep adding until you get a thick paste.
- Add this ‘slurry’ back into the pan, pour in the soy sauce and stir.
- You can leave this in your slow cooker on HIGH for about 30 minutes, or if your pan is able to go on the hob, pop onto the hob to bubble for 10 minutes until thick.
