Today I’m bringing you 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 so 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 lamb and inserted garlic and rosemary but 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!

    Hey there, I just came across your blog & am having fun reading your awesome recipes. Not a big fan of lamb (kinda weird as I grew up on a sheep farm…. long story..lol), but I love the idea of slow cooking a roast. Looks really delish and I can relate on not wanting to waste sunshine hours in the kitchen in summer too.

    1. Camilla

      Thank you, glad you found me:-)

    There’s no doubt that the slow cooker is perfect for joints of meat, and with ‘pulled’ everything being so popular now it’s a must. I also have one of those fancy fat separating jugs and agree that it’s great for getting the juices for gravy.

    1. Camilla

      Hubby did actually carve the meat but of course it just fall apart as so tender. I don’t have one of those fancy jugs so really need to get one as my turkey baster died on my and split!
