For most frozen finger food, the answer is 200°C for 8 to 12 minutes, straight from frozen, with a shake at the halfway mark. Nuggets sit at the short end, breaded prawns in the middle, curry puffs at the long end. The chart below gives per-snack settings, and if your snack is not on it, 200°C for 10 minutes with one shake is the starting point that rarely fails.
The usual problem. The packet gives oven times, because the packet was printed for an oven. An air fryer is a small, fast convection oven: same idea, hotter feel, quicker finish. Follow the oven panel and you overshoot by five minutes. These settings are for the basket, not the tray.
Ground rules, whatever the snack
- Cook from frozen. Do not thaw breaded snacks first; a thawed coating goes soggy before the fryer can crisp it.
- Single layer, with a little space between pieces. A mound cooks unevenly no matter what the timer says.
- Shake the basket or flip the pieces at halfway. Most baskets brown harder on top, and the turn is what gets both sides golden.
- Give breaded items a light spray of oil. It is the difference between pale-crisp and golden-crisp.
- The second batch runs about a minute faster. The basket is already hot.
Preheat, or not?
Three minutes at the cooking temperature before the food goes in. That is all a preheat is, and it is what makes timings repeatable, because minute one is a real cooking minute instead of a warm-up. If your model has no preheat button, run it empty for three minutes. If you skip the preheat entirely, add about two minutes to the first batch and judge by colour instead of the clock.
The chart: times and temps from frozen
| Snack | Temp | Time | Notes |
|---|---|---|---|
| Chicken nuggets | 200°C | 8 to 10 min | Shake at 5 |
| Seaweed chicken | 200°C | 8 to 10 min | Thin pieces darken fast, watch the last minute |
| Karaage or popcorn chicken | 200°C | 10 to 12 min | Shake twice for even colour |
| Fish fingers | 200°C | 10 to 12 min | Flip at 6 instead of shaking, the crumb stays on |
| Breaded prawns or ebi fry | 200°C | 8 to 10 min | Flip at 5, pull at golden, prawns overcook fast |
| Spring rolls, small | 190°C | 10 to 12 min | Spray lightly, roll them over at halfway |
| Curry puffs | 180°C | 14 to 16 min | Lower and longer so the filling heats before the pastry darkens |
| Gyoza | 180°C | 8 to 10 min | Spray well, flat side down first, flip at 5 |
| Ngoh hiang | 180°C | 10 to 12 min | Turn at halfway, slice after cooking, not before |
| Cocktail sausages | 180°C | 8 to 10 min | Shake at 4, no oil needed |
All times assume a preheated or already-warm basket and a single layer. A packed drawer for a party platter can need 2 to 3 minutes more and an extra shake.
How to tune from the chart
Air fryers vary between models more than ovens do, so treat the first run of any new snack as a calibration run. Check two minutes early. If the colour is there but the middle is cool, drop the temperature by 10 to 20 degrees and add time. If the middle is hot but the coating is pale, do the opposite: raise the heat and shorten the run.
The pattern behind every row of the chart is simple. Thick items with fillings want lower and longer, so the inside catches up before the outside burns. Thin, already-cooked items want hotter and shorter, because all you are really doing is crisping and reheating. Once a snack comes out right, write your numbers on the bag clip. From the second bag onwards, dinner is automatic.
A few snacks that play by different rules
- Cheese-filled anything. Molten cheese finds every crack. Drop the temperature 10 degrees, add two minutes, and let them rest before biting.
- Wet-battered items you froze yourself. Loose batter drips through the basket and smokes. The air fryer wants a set coating; keep raw batter for the wok.
- Very light snacks like prawn crackers or single wonton skins. The fan blows them around the drawer. Pin them under a small rack or skip them.
How to know it is actually done
Colour is not the test. The centre is. Cut the thickest piece open: it should be steaming hot in the middle, not just warm. SFA calls 5°C to 60°C the temperature danger zone for cooked food,1 and a snack that is only warm in the centre is sitting inside that zone. When in doubt, two more minutes costs you nothing.
Cooked a batch too big for the table? Cool the extras fast and get them into the fridge at 4°C or lower,2 then bring them back another day with three to four minutes at 180°C. The air fryer that cooked them is also the best tool for reviving them.
