In a small bowl, mix the oil, garlic, oregano, salt, and pepper to create a wet paste. Rub this mixture evenly over all sides of the lamb chops. To add more depth to the rub, consider mixing in up to 1 tablespoon of finely minced lemon zest, 2 teaspoons of crushed dried rosemary, 2 teaspoons of dried thyme, and/or 1 teaspoon of red pepper flakes.
Set your appliance to Air Fry at 400°F / 200°C for 18 minutes. Press Start.
When the machine beeps, indicates Add Food, or is heated to the proper temperature, put the lamb chops bone side down in the basket or on the tray so they stand up with the meat pointing up, like soldiers, on the hot surface. If they are T-bone chops, the "T" will look upside down. Each chop should be surrounded by at least 1/2 inch of space. Use separate trays or work in batches as necessary. Push the drawer in or slide the trays in gently so the chops don’t topple over.
Air fry the lamb chops without turning them, even if the air fryer prompts you to Turn Food. Cook for about 14 minutes for medium-rare, or about 16 minutes for medium-well. If using multiple trays, swap the trays from top to bottom halfway through the cooking time.
Turn off the appliance and use nonstick-safe kitchen tongs to transfer the lamb chops to a clean cutting board. Let them rest for a few minutes before serving hot.
For extra flavor, sprinkle a little crunchy kosher salt or coarse sea salt over the chops before serving.
