Preheat your airfryer: Set your airfryer to 380°F so it’s ready to go once the pork is marinated and brushed with sauce.
First cook: Place the marinated pork shoulder pieces into the airfryer basket in a single layer. Cook at 380°F for 10 minutes.
Flip and baste: After the first 10 minutes, flip the pork and brush on another layer of char siu sauce to lock in that glossy, caramelized flavor.
Second cook: Return the pork to the airfryer and cook for another 10 minutes at 380°F.
Final glaze: Flip once more, and this time brush with either honey or an extra layer of char siu sauce for added shine and sweetness.
Broil for char: Increase the heat (or use the broil function if your airfryer has one) and cook for 3 minutes until the edges are slightly charred and sticky.
Rest and serve: Remove the pork from the airfryer and let it rest for a few minutes before slicing. Serve it over rice, noodles, or enjoy it on its own!
