Remove the pork belly, if you’re using a packaged piece of pork belly there is no need to dry the skin.With a sharp knife, score the skin by slicing the rind and taking care not to cut through to the meat underneath. I highly recommend you score in the places you intend to slice the pork belly once it’s done.
Place on the rack inside your air fryer, rind side up. Spray evenly with olive oil. Cover evenly and thickly with a layer of freshly cracked salt. You can knock most of this salt off once the pork belly is done so don’t worry too much about it being salty.
Set your air fryer to 180C for 45 minutes, then check the pork belly, if you notice one side cooking faster than the other it can be a good idea to rotate the rack 180 degrees.
Turn the air fryer up to full (230C) and set another 15 minutes. Some pieces of pork belly will be ready after this, others might need another 15 minutes. Your pork belly is done when the crackling is hard and crispy. If you prefer you can brush or knock the salt off the pork belly before slicing and eating.
Different air fryers can have different cooking times so be aware of this when making your pork belly. Some air fryers may require more or less cooking time.
