Remove the grill tray from the air fryer, if it has a solid basket. If it doesn't, you'll need to add a suitably sized tin.
Put the oats, oil, seeds and honey in the air fryer basket and mix with a non-metal spoon.
Set the air fryer to 140C/285F and bake for 20 minutes, shaking every 5 minutes.
Allow to cool in the basket – this allows clusters to form - then stir in the raisins and transfer to an airtight container to keep your granola fresh.
