Cook cod fillet in an air fryer at 200°C / 400°F for 8 to 10 minutes — no flip needed. Pat dry, brush with a thin layer of oil, season, and place in a single layer. The fish is done when it flakes easily with a fork and reads 63°C / 145°F internal at the thickest part. Cod is leaner than salmon, so it dries out faster — pull on the early side.
| Size | Time |
|---|---|
| Thin (1.5cm / ½ inch) | 6–8 min |
| Standard (2.5cm / 1 inch) | 8–10 min |
| Thick (3.5cm / 1½ inch) | 11–14 min |
| From frozen | 14–18 min |
Frozen cod works well — no thaw needed. Rinse off ice glaze, pat dry, cook at 200°C / 400°F. Add 4 to 6 minutes vs fresh.
Cod is done when the flesh turns from translucent to opaque white throughout and flakes easily with the gentle press of a fork. Internal temp reads 63°C / 145°F (USDA safe minimum for fish). Past 65°C / 150°F it goes from flaky to dry and crumbly fast — pull on the early side.
Cod is one of the leanest fish — under 1% fat versus 13% for salmon. That's why it dries out so quickly past the right doneness: there's no fat to keep the muscle fibres moist as proteins contract. The rapid air circulation of an air fryer helps because it cooks fast, minimising the time fibres are squeezed.
Read the science →No. Cod is delicate and easy to break when flipped. Cook in a single layer without flipping; the rapid air circulation cooks both sides evenly.
Yes — rinse off the ice glaze, pat dry, and cook at 200°C / 400°F for 14 to 18 minutes. Don't try to season frozen because the seasoning will run off; brush with oil and season after a minute or two of cooking.
Two causes: wet fillet (pat completely dry) or no oil (brush with a thin coat). Some fryers benefit from a sheet of parchment paper for delicate fish — cut it to size with holes for circulation.
Two signals: the flesh turns from translucent to opaque white throughout, and a fork inserted into the thickest part lifts a flake cleanly. Internal temp reads 63°C / 145°F (USDA safe minimum for fish).
