01 - Whisk together olive oil, chopped rosemary, minced garlic, kosher salt, black pepper, lemon zest, and lemon juice in a small bowl until thoroughly combined.
02 - Pat lamb chops completely dry with paper towels. Place in a shallow dish or large zip-top bag and pour marinade over the meat, ensuring each chop is evenly coated on all sides.
03 - Let lamb chops marinate at room temperature for at least 15 minutes, or refrigerate for up to 2 hours for deeper flavor penetration. Overnight marinating yields the most robust taste.
04 - Preheat air fryer to 400°F for 3 minutes to ensure proper cooking temperature.
05 - Place lamb chops in a single layer in the air fryer basket, leaving space between each piece. Cook in batches if necessary to prevent overcrowding and ensure even cooking.
06 - Cook lamb chops for 6 minutes to develop initial sear and begin cooking process.
07 - Turn chops over and cook for an additional 5 to 6 minutes until medium-rare (internal temperature reaches 135°F). Extend cooking time by 2-3 minutes per side for medium doneness.
08 - Transfer lamb chops to a cutting board or serving platter and let rest for 3 minutes, allowing juices to redistribute throughout the meat for optimal tenderness.
09 - Arrange chops on serving plates, garnish with fresh rosemary sprigs, and accompany with lemon wedges for squeezing over the meat.
