01 - Preheat the air fryer to 400°F for 3 minutes to ensure optimal cooking temperature.
02 - Pat the lamb chops completely dry with paper towels. Rub both sides thoroughly with olive oil, then evenly coat with kosher salt, black pepper, garlic powder, and dried rosemary.
03 - Arrange the seasoned lamb chops in a single layer in the air fryer basket. Cook for 6 minutes, then flip and continue cooking for 4 to 6 minutes for medium-rare doneness. Adjust time based on chop thickness and desired doneness.
04 - While lamb cooks, melt butter in a small saucepan over medium heat. Add minced garlic and sauté for 1 minute until fragrant. Stir in lemon zest and lemon juice, then remove from heat. Fold in chopped fresh parsley.
05 - Transfer cooked lamb chops to a serving plate and let rest for 3 minutes to allow juices to redistribute. Drizzle generously with the warm lemon butter sauce before serving.
