Air Fryer Recipe
Battered Cod Bites
A delicious and easy-to-make battered cod bites recipe, perfect for air frying.
Ingredients
- 500g cod fillets, cut into bite-sized pieces
- 150g plain flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 200ml cold sparkling water
- 1 egg
- 1 tablespoon malt vinegar (optional, for seasoning)
- cooking spray
- lemon wedges
- tartar sauce
Method
- Preheat air fryer to 200°C (390°F).
- In a bowl, whisk flour, baking powder, salt, and pepper.
- In another bowl, mix sparkling water and egg, then fold into dry ingredients to make batter.
- Pat cod pieces dry, dip in batter, and place on a plate.
- Coat air fryer basket with cooking spray.
- Place cod bites in basket in a single layer, spray tops with cooking spray.
- Cook for 10-12 minutes, flipping halfway, until golden brown and crispy.
- Remove with tongs and cool slightly on a wire rack.
Why this works in an air fryer
Cold sparkling water and baking powder add gas bubbles, while minimal mixing limits gluten so the coating stays light rather than bready. Patting the cod dry helps batter cling, and the air fryer’s fast convection dehydrates the sprayed surface quickly enough to set and brown it before the fish overcooks.
Equipment notes
Assumes a 5–6 litre basket with room for one uncrowded layer; smaller baskets need batches. In a single-drawer model, keep the thickest pieces towards the hotter rear/centre and flip once. In dual-zone fryers, split evenly between drawers and expect 1–2 minutes extra if both zones are running.
Common pitfalls
- Batter pooling under the cod within the first few minutes? The fish is too wet or the batter is too loose; re-dry the pieces, let excess batter drip off, and whisk in 1–2 tablespoons more flour before the next batch.
- Pale, floury patches at minute 10? Those areas have not had enough oil to conduct heat and brown; spray until the dry spots look lightly damp, then cook for another 2 minutes.
- Coating tearing away when flipped? The batter has not set or the basket was under-oiled; wait until about minute 6, loosen with a thin silicone spatula, and oil the basket more thoroughly for the next batch.
- Golden outside but slightly translucent fish in the centre? The pieces are too large for the coating time; cut closer to 3cm chunks or return the thick pieces for 2–3 minutes at 180°C to finish without over-darkening the batter.
Variations & substitutions
- Swap cod for haddock: it flakes more readily, so handle with a spatula rather than tongs and start checking from 9 minutes.
- Use pollock or coley: the leaner flesh can dry faster, so keep the pieces slightly larger and remove as soon as they flake.
- Replace half the plain flour with cornflour: the coating turns crisper and lighter but browns a little paler, so rely on texture as well as colour.
- Use cold beer instead of sparkling water: malt sugars brown faster, so check early and reduce the temperature to 190°C if the batter darkens before the fish is cooked.
Storage & reheating
Keep leftovers chilled for up to 2 days, then reheat in the air fryer at 180°C for 4–6 minutes on a rack or in a single layer until hot and re-crisped.
