This Air Fryer Butterflied Lamb Leg Joint is a fuss free way to roast lamb. It's quick to cook and unlike many cuts of lamb, extremely easy to carve. It’s a great option for a weeknight dinners, but impressive enough for a Sunday feast or entertaining. Vary the seasonings and lamb is incredibly versatile too.
If your air fryer requires pre-heating, start this setting now.
Thoroughly dry a 600g Boneless Lamb Leg Joint.
Drizzle over 2 tsp Vegetable Oil and ½ tsp Sea Salt Flakes and thoroughly coat the lamb in both.
Place the lamb leg joint into the air fryer basket.
Air fry for 15 minutes at200c/390f.
Use tongs to turn the lamb over and air fry for a further 10 minutes at 200c/390f.
Check the lamb is cooked to your liking. If you prefer it more cooked, put it back in for 2 minutes at a time.
Take the lamb out the air fryer and wrap well in foil. Allow to rest for around 10 minutes while you make the gravy.
Remove the crisper plate from the basket and tip the juices and fat into a small saucepan. Use a silicone spatula to make sure you get all the goodness. Scrape any tasty bits off the crisper plate too.
To Make The Lamb Gravy
Start heating the cooking drippings over a high heat.
Add 300ml Water to the pan. Freshly boiled from the kettle will speed up the process.
Mix 3 tbsp Cornflour with roughly 3 tbsp Wateruntil all the cornflour has dissolved.
Once the juices and water have come to the boil, add the cornflour slurry with one hand while whisking with the other.
Continue to boil until the gravy is thickened. If after a few minutes, it is not thick enough for your liking, make up and add more cornflour slurry - add a little at a time. If it is thicker than you would like, add a little water at a time.
Taste the gravy and add Sea Salt Flakes a little at a time until the gravy is flavoursome. Don't be shy, salt is your friend with gravy.
Serve with the sliced lamb.
Notes
Oil - Choose your oil to match your flavouring. For example use garlic, salt and rosemary with olive oil or for a more neutral flavour, sea salt and black pepper with vegetable oil.
Seasoning - Choose any seasoning mix, spices or dried/fresh herbs. Make sure that salt is included in the mix. You can also add a little citrus juice.
I used vegetable oil with a 2:1 mix of garlic salt and paprika.
The air fryer version of this recipe is tested in a Cosori Lite (CAF-LI401S) with a 3.8 litre capacity. The square(ish) shaped basket is 21cm x 21cm and 24cm on the diagonal.
Not all models advise preheating is required. Please follow the recommended instructions for your model. Mine has a specific preheat setting which is 4 minutes at 205c.
For this recipe, I can easily fit a 600g butterflied leg in the basket at a time. This gives plenty of room to allow air to circulate.
As all air fryer models are a little different, you may find that you can fit more or less in at a time. Some models include stacking shelves which will increase capacity.
Required cooking times and temperatures can also vary between models and brands. If you know that your air fryer runs a little hotter than most recipes suggest, use a lower temperature. And vice versa. Equally if you find that food cooks more quickly in your machine than instructions usually state, reduce the cooking time (or check it earlier) and vice versa.
