01 - Pat the lamb chops completely dry with paper towels to ensure proper searing.
02 - In a mixing bowl, whisk together olive oil, chopped rosemary, minced garlic, kosher salt, black pepper, and lemon zest until well combined.
03 - Rub the marinade mixture evenly over both sides of each lamb chop, ensuring full coverage. Let marinate for at least 10 minutes at room temperature, or up to 1 hour for deeper flavor penetration.
04 - Preheat the air fryer to 400°F for 3 minutes before cooking.
05 - Place the lamb chops in a single layer in the air fryer basket, ensuring they are not touching. Cook in batches if necessary to avoid overcrowding.
06 - Air fry for 6 minutes to develop initial sear and crust.
07 - Flip the lamb chops using tongs and cook for an additional 5 to 6 minutes for medium-rare doneness (internal temperature should reach 135°F). For medium, add 2 more minutes per side.
08 - Transfer the lamb chops to a clean plate and cover loosely with aluminum foil. Let rest for 5 minutes to allow juices to redistribute.
09 - Plate the lamb chops and garnish with fresh lemon wedges and rosemary sprigs if desired.
