Prep the chops: Pat pork chops dry. Use a fork to lightly prick both sides.
This helps the marinade soak in.
Make the marinade: In a bowl, mix fish sauce, soy sauce, brown sugar, honey, oil, garlic, shallot, lemongrass, black pepper, five-spice (if using), lime juice, sesame oil, and water. Stir until sugar dissolves.
Marinate: Add chops to a zip-top bag or shallow dish and pour in the marinade. Coat evenly.
Marinate at least 1 hour in the fridge, ideally 4–12 hours. Flip once halfway.
Preheat the air fryer: Set to 400°F (200°C) for 3–5 minutes. Lightly spray the basket with oil to prevent sticking.
Drain excess marinade: Let extra marinade drip off to avoid smoking.
You can pat lightly with a paper towel. Reserve a tablespoon of the marinade (not touching raw meat) to brush midway for extra gloss, or make a fresh brushing sauce.
Air fry the first side: Place chops in a single layer with space around each one. Cook at 400°F (200°C) for 6–8 minutes, depending on thickness.
Flip and finish: Flip, brush with a bit of fresh marinade or honey-water mix (1:1), and cook another 5–7 minutes, until the edges caramelize and internal temp reaches 145°F (63°C).
Rest: Transfer to a plate and rest for 5 minutes.
This keeps the juices in.
Serve: Plate over rice with cucumbers, herbs, and pickles. Add a fried egg if you like. Drizzle with a little nuoc cham for brightness.
