Preheat your air fryer to 400°F (200°C) for 3–5 minutes.
A hot basket helps the fish cook evenly and get that light golden edge.
Pat the cod dry. Use paper towels to blot both sides thoroughly. Dry fish browns better and doesn’t steam.
Season the fillets. Brush with olive oil on both sides. In a small bowl, mix salt, pepper, garlic powder, onion powder, and paprika.
Sprinkle evenly over the cod. Add a little lemon zest on top for brightness.
Prepare the basket. Lightly spray the air fryer basket with nonstick spray to reduce sticking. If you have a perforated parchment liner made for air fryers, you can use it too.
Arrange the cod in a single layer. Leave a bit of space between fillets.
Don’t stack or overlap—air needs to circulate for even cooking.
Air fry for 8–10 minutes. Thinner pieces may be done around 7–8 minutes; thicker fillets can take up to 12. The fish is done when it flakes easily and reaches an internal temperature of 145°F (63°C).
Check for doneness early. At the 7-minute mark, peek and test with a fork. If it flakes and looks opaque, you’re good.
If not, give it another 1–2 minutes.
Finish with lemon and herbs. Squeeze fresh lemon juice over the top and sprinkle with chopped parsley or dill. Serve right away for the best texture.
