Fold 4 paper towels in half (so it’s 2 paper towels long, twice as thick). Run under faucet to wet, squeeze gently to remove excess water.
Lay on a plate with frozen potstickers in the middle. Fold wet paper towels over the top of them.
Microwave for 2 minutes, or until the middle of each is not frozen/hard any longer.
Preheat air fryer to 400 degrees F for 5 minutes.
Put defrosted potstickers into basket and spray generously with olive oil spray.
Set to 6 minutes total. Flip every 2 minutes and spray tops each time you flip over.
Remove once they’re as crispy as you’d like them to be.
