What do you need?

Lamb roast

The recipe uses a boneless leg of lamb. However, one of the great things about this recipe is that you can actually use any type of roast lamb joint.

I usually use boneless leg of lamb, but lamb rump roast, and lamb loin roast are also great options.

Seasoning

This recipe uses fresh rosemary and thyme, along with a little salt and pepper. You can also use dried herbs if that is what you have.

Feel free to substitute any other herbs or spices that you like with lamb, you can add a little garlic powder for some extra flavor, or use a pre-made seasoning mix like Moroccan or Greek spices.

Oil

I normally use light olive oil when cooking a roast in the air fryer, but you can use any cooking oil that you would usually use in your air fryer. Vegetable oil or avocado oil are good choices.

Tip

Choose a cooking oil with a high smoke point to reduce the chance of your air fryer smoking.

How to roast lamb in the air fryer

  1. Preheat the air fryer to 180°C/ 360°F for 2-3 minutes.
  2. Prepare lamb. Pat the lamb roast dry with paper towels, then drizzle oil over the lamb, then add the salt, pepper, and herbs, and rub into the lamb.
    Note: If you are using fresh rosemary, pick the leaves off and chop them up quite finely before using them.
Tip

For an easy way to season your lamb, mix the herbs, salt and pepper together with the oil on a plate and roll the lamb in it.

  1. Air fry lamb roast. Cook the roast lamb in the air fryer at 180°C/ 360°F for 20 minutes, until cooked to your liking. See the section below on how long to air fry lamb for more details and for other sized lamb roasts.

  1. Rest lamb. When the lamb is cooked to your liking, remove it to a plate or cutting board, cover with foil, and leave to rest for 10 minutes. This allows the juices to reabsorb into the meat before you cut it, ensuring it stays moist.

How long to cook roast lamb in the air fryer?

The exact cooking times for a lamb roast in the air fryer depend on a few factors, including the exact size and shape of the lamb joint you are using, as well as how powerful your air fryer is.

However, my rule of thumb to calculate lamb roast air fryer cooking times is: 10 minutes per 450g/ lb for rare, then add five minutes for each degree of doneness that you like. Use this as a starting point, and monitor the internal temperature of the lamb when it is close to the end of the cooking time until it is cooked to your liking.

Note: the USDA states that roast lamb should be cooked to a minimum of 145°F / 63°C, which is medium-rare.

Tip

Remember that the temperature of the meat will continue to rise a few degrees while it rests.

These cooking times were tested with my Philips XXL Airfryer. If you have another powerful brand of air fryer like the Nuwave or a Ninja Foodi then expect cook times to be similar.

Serving ideas

It’s hard to beat a traditional roast lamb dinner with crispy roasted potatoes, fresh vegetables like carrots and peas, and rich brown gravy ladled over the top. But roasted lamb is also delicious served with salad, or in wraps or pita bread drizzled with garlic yogurt (or try tzatziki for a Greek-inspired flavor).

Here are some tasty side dishes that go well with this recipe:

For a simple dressing, you can make an easy homemade mint sauce by mixing finely chopped fresh mint leaves with a sprinkle of sugar and a splash of vinegar (adjusting both to taste). It looks a little rustic, but tastes fantastic!

Also want to air fry a side dish?

If you also want to cook side dishes in the air fryer, you can pre-cook them for part of the cooking time before the lamb, then put them back in the air fryer to finish cooking for 10 minutes while the lamb is resting.

Storing and reheating

Store any leftover lamb roast in an air-tight container in the refrigerator, and use within 3 days.

You can reheat lamb roast in the air fryer: air fry for 3-4 minutes at 180°C/ 360°F until heated through.
