Moist and delicious, 2 Ingredient Slow Cooker Roast Lamb is prepared in seconds. You won’t want to roast a leg of lamb in any other way once you’ve tried this! Simply sprinkle a lamb stock cube into the lamb and switch on your slow cooker or Crockpot! That’s it, no liquid required!
Today I’m sharing my stupidly easy plus utterly moist and delicious 2 Ingredient Slow Cooker Roast Lamb.
As we head into summer and look forward to balmy hot days I really don’t want to spend much time cooking or switch the oven on in an already hot kitchen. Last Sunday it was a sweltering day and I had a virus. The last thing I wanted to do was cook or wash up lots of greasy, burnt pans but I had a half a leg of lamb that needed cooking.
So instead of roasting it in the oven along with potatoes I decided a less messy and cooler solution would be to roast the lamb in the slow cooker and to make ActiFry roast potatoes. Then all I had to do was boil/steam some vegetables and make some gravy.
In the past I have made cuts into the leg of lamb and inserted garlic and fresh rosemary.
However this really was one of those days where even the bear minimum was a huge effort so I decided that hubby’s idea of just sprinkling over a lamb stock cube for a bit of flavour enhancement sounded like a fab idea.
If you have a cook’s syringe or one of those fancy jugs that separates the fat from the meat juices then you can add the latter to your gravy for a great flavour boost.
We were all in food heaven eating our lamb Sunday roast, the meat was really tender and falling off the bone and the the stock cube really enhanced the lamb flavour! I was very happy to not have messed up my oven with all the lamb fat and there were no cumbersome roasting tins to wash up.
So summer or winter I will definitely be using the slow cooker to roast all my lamb joints from now on and it’s so energy efficient too!

Good morning! Just about to try out this 2ingredient leg of lamb recipe! It’s just under 1kg…how long cooking in slow cooker on “low” setting please? Many thanks & have a great day
Camilla
Hi Sheila the recipe is for a 1 Kg half leg of lamb so just follow the instructions and you’ll be fine, just check after the shorter amount of time.
Lucy
I want to make this tomorrow, I have a 1kg half leg with the bone in.. do I still need to do it for 8 hours on low?
Thanks
Camilla
Yes that’s exactly what I use in the recipe so 7 – 8 hrs on low:-)
Jonathan
Just made this for Sunday lunch, it was fantastic. Really pleased with how it came out so full of flavour and tender. The Left over juices also helped make a good gravy. Some mint sauce on the side and roast potatoes, yum, the family were very happy. I am sooo doing this recipe again. Thanks for the recipe!
Camilla
Thank you for your feedback Jonathan, it is such a winner of a recipe isn’t it:-)
Mr Bev HOLDING
Hi Camilla,
Have used this recipe many times with great success. I’m now wanting to use a full 2kg leg ( having bought a 6.5l slow cooker),. please could you advise me of the revised cooking times.
Many thanks
Bev
Camilla
Hi Bev, I would say it would be 5 – 6 hrs on high or 9 – 10 hrs on low.
Mr Bev HOLDING
Many thanks
Camilla
Pleasure, I’ve also added the info to the post:-)
Maxine

Camilla

Sandra Slater
I also sprinkle beef stock cube on roast potatoes.
My mums recipe for lamb was cover lamb in English mustard then add brown sugar. Oh so good!!
Camilla
Fab, I put a seasoned semolina mix on our roast spuds https://www.fabfood4all.co.uk/crispy-coated-roast-potatoes/ . Your mum’s lamb sounds similar to what I do with our gammon at Christmas so bet that tastes good:-)
Bettylou Ackerson
I’ve just read your receipe for doing lamb in the crockpot. I’ve never heard of lamb stock cube. Must be something British. Can I use a beef cube. We only have chicken and beef where I live Will this work
Camilla
Hi Bettylou yes I’m sure a beef stock cube would work just as well!
Terry Anderson
It has started burningbmy lamb after about an hour, what should I do? Please help
Camilla
Hi Terry, I’ve never heard of this happening and this is my most popular recipe. Do you have a metal crockpot as opposed to porcelain? If you had it on high I would turn down to low also.
Cas
Tried this for Sunday roast with family.
Was perfect. All meat being done like that in future..
so easy.
Thank you
Camilla
Excellent Cas, so glad you like it. It doesn’t work with normal roast beef I should warn you (a bit tough, I tried), so brisket would be the one to pick if wanting beef! Chicken also fine, you just don’t get a crispy skin.
Stuart
Hi. Made this yesterday and it was delicious.
Thank you.
Was wondering could you do a similar thing with a beef roasting joint with a beef stock cube?
Camilla
Hi Stuart, I did actually try this without much success, it was edible but sweaty & tough from memory. I think the bone in the lamb is the difference.
Joanna Wood
Do you not need to add water?
Camilla
No, it really is that simple:-)
