Don't skip the oil spray – it's the #1 reason pizza rolls come out pale instead of golden. Single layer only – overcrowding traps steam and ruins crispness. Leftovers last 3 days in the fridge; reheat in air fryer at 350°F for 2-3 minutes (microwave makes them soggy). Flaky salt is a game-changer – add it right out of the fryer for texture and salinity.
