Prep the lamb: Pat the cutlets dry with paper towels. In a bowl, toss with olive oil, salt, pepper, garlic, and oregano until evenly coated.
Let sit at room temperature for 10–15 minutes while you make the pesto.
Make the mint pesto: In a food processor, add mint, parsley, garlic, nuts, lemon juice and zest, Parmesan (if using), and honey. Pulse, then stream in olive oil until you get a spoonable sauce. Season with salt and pepper.
Adjust with more lemon or oil as needed.
Preheat the air fryer: Set to 400°F (200°C) for 3–5 minutes. A hot basket helps sear the lamb.
Arrange the cutlets: Place the lamb in a single layer in the basket, leaving space between pieces. Work in batches if needed to avoid crowding.
Cook: Air fry for 6–8 minutes total, flipping halfway.
For medium-rare, aim for an internal temperature of 130–135°F (54–57°C) when you pull them; they’ll rise a few degrees while resting.
Rest: Transfer cutlets to a plate and rest for 5 minutes. This helps keep them juicy.
Serve: Spoon mint pesto over the lamb or serve on the side. Add lemon wedges for extra brightness.
