Prep the chops: Pat the lamb loin chops dry with paper towels. Dry surfaces brown better and faster.
Make the seasoning: In a small bowl, mix olive oil, minced garlic, chopped rosemary, thyme, salt, pepper, smoked paprika, and the zest of half a lemon.
Coat evenly: Rub the mixture all over the chops, covering both sides and the edges.
Let them sit at room temperature for 10 minutes while you preheat.
Preheat the air fryer: Heat to 400°F (200°C) for 3–5 minutes. A hot basket helps with browning.
Arrange the chops: Place the chops in a single layer in the basket, with a little space between them. Work in batches if needed.
Do not crowd.
Cook: Air fry for 7–9 minutes, flipping halfway. For medium-rare, aim for 130–135°F (54–57°C) internal temperature. For medium, 140°F (60°C).
Use an instant-read thermometer for accuracy.
Rest: Transfer to a plate and tent loosely with foil for 5 minutes. This lets juices redistribute.
Finish and serve: Top with a small pat of butter (optional) and a squeeze of lemon. Serve with roasted veggies, a simple salad, or garlic mashed potatoes.
