Brush both sides with a high-heat oil like avocado or olive oil.
Sprinkle the flesh side with salt, black pepper, garlic powder, and a pinch of paprika.
Set your air fryer to 400°F and let it warm up for 3 minutes.
Place the fillets skin-side down in a single layer in the basket, leaving space between them.
Air fry for 7 to 9 minutes, depending on the thickness of your fillets.
The fish is done when the flesh is opaque and flakes easily with a fork (or reaches an internal temperature of 140°F to 145°F).
