Frozen Fish in the Air Fryer
Frozen fish is one of the quickest dinners there is, but the oven makes it slow and the crumb often comes out patchy and pale. Air fryer frozen fish goes from the freezer to crisp and golden in 12 to 16 minutes, with no thawing and almost no oil. This page covers breaded and battered fillets, fish fingers, fish cakes and plain fillets, with a time and temperature for each.

Why the air fryer works for frozen fish
Cooking air fryer frozen fish takes advantage of what the machine does best: crisping a coating quickly. A fan oven heats slowly and dries the crumb out in patches, while a frying pan can leave the outside greasy and the inside cold. In an air fryer, the hot air surrounds the fillet, so the crumb or batter sets in the first few minutes and the fish steams gently inside.
Frozen fish in an air fryer is also fast and cheap to run. A basket of fillets is ready in about 14 minutes, so you can cook the chips alongside, and you do not need to defrost anything. Because these are ready-to-heat products, what matters is that the middle is steaming hot all the way through, which a thermometer confirms in seconds.

Time and temperature by type
How long to cook frozen fish in an air fryer depends on what it is. Thin, breaded fillets and fish fingers are quick, while thick battered fillets and fish cakes need longer. Breaded fillets take 12–14 minutes at 190 °C. Fish fingers take 8–10 minutes at 200 °C. Frozen fish cakes need 14–16 minutes at 190 °C. Battered fillets need 16–18 minutes at 180 °C so the batter does not burn before the fish is hot. The variants table lists each one.
Tips
- Keep it frozen. Defrosted coating absorbs moisture and goes soft. A solid, frozen fillet crisps best.
- Do not stack or overlap. Cook in a single layer, and in two batches if you need more than will fit. Fish in a crowded basket steams.
- Always check the middle. Packet times are for ovens. An air fryer is hotter, so start checking a minute or two early.
Serving
Serve with chips and peas, a spoonful of tartare sauce and a lemon wedge for the classic. Frozen fish and chips can share the air fryer if you cook the potato wedges first and keep them warm. Homemade versions are in cod in the air fryer, and fish cakes have their own page.
Storing and reheating
Cooked fish is best eaten straight away. If you have leftovers, cool them quickly, keep them covered in the fridge and eat within 1 day. Reheat at 160 °C for 4–5 minutes, until steaming hot all the way through (75 °C in the centre). Never refreeze fish that has been cooked from frozen.
Variations
- Fish finger sandwich: Serve the cooked fingers in soft white bread rolls with tartare sauce and lettuce.
- Fish tacos: Break up the cooked fish and serve in warm tortillas with shredded cabbage, lime and a yoghurt dressing.
- Gluten-free fish: Check the packet for a gluten-free coated range, and use the same time and temperature.
Troubleshooting
- The coating is soggy
- Do not thaw the fish and do not crowd the basket. Cook it from frozen in a single layer, with a light brush of oil on the basket, and the coating will crisp.
- The batter is dark but the fish is cold in the middle
- Large or thick battered fillets need longer at a lower heat. Cook at 180 °C for 16–18 minutes instead, and check the middle reaches 75 °C.
- The coating sticks to the basket
- Brush the basket or a perforated baking paper liner with a little oil, and turn the fish gently with a spatula once the underside has set.
Frequently asked questions
How long does frozen fish take in an air fryer?
Breaded fillets take 12–14 minutes at 190 °C, fish fingers 8–10 minutes at 200 °C, fish cakes 14–16 minutes at 190 °C and battered fillets 16–18 minutes at 180 °C. All should be steaming hot at 75 °C.
Can you cook frozen fish in an air fryer without breading?
Yes. Plain frozen white fish fillets need 14–16 minutes at 180 °C, brushed with oil and seasoned after the first 5 minutes. They are cooked when opaque and at about 60 °C, which is common kitchen practice for white fish.
How long do frozen fish fingers take in an air fryer?
About 8–10 minutes at 200 °C, turned halfway. See the fish fingers page for full details.
Do you need to preheat the air fryer for frozen fish?
It helps. A hot basket sets the coating straight away, so it crisps rather than steams. Three minutes is enough.
