Step 1

In a medium bowl, mix the olive oil, lemon juice, rosemary, salt and pepper together. Add the lamb and toss to coat. Set aside to marinate for as little as 10 minutes up to 2 hours (see note).

Step 2

Preheat the air fryer to 400°F. Once hot, remove the basket and use tongs to put in the chops, ideally in a single layer. (If you’re using a smaller air fryer, you may need to cook in batches.)

Step 3

Put the basket back into the air fryer. Set the timer for 5-7 minutes depending on thickness and temperature of the chops, and then let the chops cook.

Step 4

Take out the basket and flip the lamb chops using the tongs. Set the timer for 5-7 minutes more for medium-rare.

Step 5

Check doneness by inserting an instant-read thermometer into the middle of a large chop: 125°F is rare, 135°F is medium-rare, 145°F is medium and 150-160°F is medium-well to well-done. You can put the lamb back in for a few more minutes to reach your desired doneness.

Step 6

Let the lamb rest for 3 minutes to let the juices redistribute before serving.
