Bring chops to room temp: Take the pork chops out of the fridge 15–20 minutes before cooking. This helps them cook evenly and stay juicy.
Preheat the air fryer: Set to 400°F (200°C) for 5 minutes.
A preheated basket gives better browning.
Mix the seasoning: In a small bowl, combine salt, pepper, garlic powder, onion powder, paprika, dried thyme or oregano, and cayenne if using.
Prep the chops: Pat the pork chops dry with paper towels. Rub both sides with oil, then coat generously with the spice mix, pressing it into the surface.
Arrange in the basket: Place the chops in a single layer in the air fryer basket. Do not overlap. Work in batches if needed.
Cook: Air fry at 400°F (200°C) for 8–10 minutes total, flipping halfway.
Start checking at 7 minutes if your chops are thinner.
Check doneness: Use an instant-read thermometer. Pull at 140°F (60°C); the temp will rise to 145°F (63°C) while resting.
Rest and finish: Let rest 5 minutes. Brush with melted butter if you like, and squeeze a little lemon over the top.
Serve: Pair with low-carb sides like roasted broccoli, cauliflower mash, or a crisp salad.
