Tips

Dry the Cod Really Well

This is the most important step and it’s easy to rush through. Use a few paper towels and press down firmly on all sides of each fillet to soak up as much moisture as you can.

Cod holds a lot of water, and if the surface is still wet, the lemon butter mixture won’t stick properly. You’ll end up with most of it sliding off and pooling at the bottom of the basket.

Dry fish also means better texture. That lightly golden top you’re going for only happens when the surface isn’t steaming from excess moisture.

Use Cod Fillets That Are Similar in Size

If one fillet is thin and another is twice as thick, they’re not going to finish cooking at the same time. The thin one will be overdone and dry while the thick one is still raw in the middle.

Try to pick fillets that are roughly the same thickness, ideally around 1 to 1.5 inches. If you can only find a large piece, cut it into portions that are close in size so everything cooks evenly.

Let the Fish Come to Room Temperature

Take the cod out of the fridge about 15 minutes before you start cooking. Cold fish straight from the fridge cooks unevenly because the outside gets done way before the inside has a chance to catch up.

This is especially true in an air fryer where the heat is intense and the cook time is short. Letting it sit out briefly helps the fillet cook through at the same rate so you don’t get dry edges with a cold center.

Just don’t leave it out longer than 20 minutes. You still want to keep things safe.

Frequently Asked Questions

Can I use frozen cod fillets instead of fresh?

Yes, but you need to fully thaw them first before cooking. Place the frozen fillets in the fridge overnight or use a cold water bath to thaw them more quickly.

If you try to air fry them from frozen, the lemon butter mixture won’t stick properly and the fish will cook unevenly. Always pat the thawed fillets really dry with paper towels so the coating adheres well.
