Slow Cooker Roast Lamb Leg

In my world, there are only 2 ways to cook a leg of lamb: either perfectly cooked so it’s pink and juicy inside (see my classic Roast Lamb with Gravy), or long and slow so it’s fall apart tender.

There is no in between!

Well, there is. But it’s dry and no amount of gravy can salvage it. It’s also very sad. 😂

Fall-apart-tender slow cooked lamb leg can either be done in the oven or in the slow cooker. Click here for the slow roasted oven recipe, this is the slow cooker version!

I know it sounds counter-intuitive to use the words “roast lamb” and “slow cooker” in the same sentence. But actually, it’s the right description for this recipe because it is cooked in the slow cooker and finished off in the oven to get that beautiful browning. And also to reheat it, in case the slow cooker finished and it was sitting on the warm function for a while.

My slow cooker is a standard size round one and I was able to fit in a 1.9kg / 3.8lb lamb leg purchased from the grocery store (Woolworths in Australia) because the shaft of the leg comes cut so it can be bent to fit into the slow cooker. Vereeee practical!

I’ve used a small full lamb leg here, but it can easily be made with half lamb legs which don’t have the shaft so they will easily fit inside a standard slow cooker.

And of course, if you have one of those oval shaped slow cookers, you could make this with a full size lamb leg! After all, arguably one of the best things about roast lamb are the leftovers. Sandwiches with lamb and gravy. SO GOOD!!!

Gravy for Roast Lamb

And while it’s browning in the oven, we make a quick gravy using the juices in the slow cooker.

No need to deal with the clunkiness of making the gravy in a roasting pan, like you do when you roast lamb in the oven. Nope, this is a super simple one made in a saucepan using butter instead of the drippings in the roasting pan. And of course the juices left in the slow cooker.

All. That. FLAVOUR!

This is the sort of food made for sharing with family and friends. I know there’s something grand about placing a whole lamb leg on the table as a centrepiece. But a pile of incredibly juicy, tender lamb is just as impressive in my books – and there’s no need to pass the plates over and wait for it to be carved. Just dive right in! – Nagi xx
