Pat the pork roast dry. If the pork roast has a rind, score the skin with a sharp knife in a criss-cross pattern, cutting into the fat beneath, but not into the meat.
Sprinkle salt over the skin and rub in [Note 2]. Leave the pork roast for 10 minutes to allow the salt to draw the moisture from the skin.
Pat the pork roast dry again, then drizzle with oil and rub in.
Preheat air fryer oven to 360°F/ 180°C.
Place pork roast in air fryer basket, and cook for 50 minutes (25 minutes per lb of meat).
When the cooking time is up, check that the pork is cooked to ensure it has reached 145°F/ 63°C in the center of the thickest part [Note 3].
Remove pork roast from air fryer, cover with kitchen foil and leave to rest for ten minutes before serving [Note 4].
Carve into slices to serve [Note 5].
