01 - In a small bowl, whisk together olive oil, chopped rosemary, minced garlic, kosher salt, black pepper, lemon zest, and lemon juice until thoroughly combined.
02 - Pat the lamb chops completely dry with paper towels. Place in a shallow dish or large zip-top bag and pour the marinade over, turning to ensure each chop is evenly coated.
03 - Let the lamb chops marinate at room temperature for at least 15 minutes, or refrigerate for up to 2 hours for deeper flavor penetration.
04 - Preheat the air fryer to 400°F for 3 minutes to ensure proper cooking temperature.
05 - Place the lamb chops in a single layer in the air fryer basket, cooking in batches if necessary to avoid overcrowding. Air fry for 6 minutes.
06 - Flip each chop using tongs and cook for an additional 5 to 6 minutes until medium-rare (internal temperature reaches 135°F). Adjust cooking time according to preferred doneness.
07 - Transfer the lamb chops to a serving platter and let rest for 3 minutes to allow juices to redistribute throughout the meat.
08 - Garnish with fresh rosemary sprigs and serve with lemon wedges on the side if desired.
