Prep. Preheat the air fryer to 400F. Brush both sides of each lamb chop with oil, and season with salt and black pepper.
Cook on the first side. When the air fryer is preheated, put the lamb chops into the basket, making sure they aren’t touching. Air fry the lamb chops for 6 minutes on the first side.
Cook on the second side. Use tongs to flip them over and air fry 4 to 6 minutes longer, or until they reach your desired level of doneness (see Notes).
For the Rosemary Garlic Sauce:
Combine all ingredients in a small bowl.
To Serve:
Serve the lamb along with the sauce to spoon on top.
Notes
How to Tell if Lamb is Done: The American Lamb Board says that 1 to 1.25-inch thick lamb chops take about 9 to 12 minutes to reach an internal temperature of 145F, which is considered medium-rare. I find that 1.25-inch thick lamb loin chops cooked at 400F in the air fryer take 11 minutes total cooking time for medium rare and 13 minutes for medium well.
Storage: After cooling to room temperature, store leftovers covered in the fridge for up to 4 days.
