Most frozen foods cook in an air fryer at around 200C/400F in 10 to 20 minutes, straight from the freezer with no thawing. Fries and fish fingers land near the shorter end, while thicker items like spring rolls and larger nuggets take a little longer. The exact time depends on your model, the size of the batch and how packed the basket is, so treat every number here as a starting point and check for doneness before serving.
The general approach
Frozen food is one of the things air fryers do best, because the hot circulating air crisps the outside while the inside heats through. A few habits make it reliable every time:
- Don’t thaw first. Cook from frozen. Most packaged frozen foods are designed for it, and thawing usually makes them soggy.
- Preheat if your model allows it. A short preheat gives food a hotter start, which helps it crisp instead of steam. It’s optional but useful — see do you need to preheat an air fryer.
- Spread food in a single layer. Overcrowding traps steam and leads to uneven, softer results. Cook in batches if you have to.
- Shake or turn partway through. Around the halfway mark, shake the basket or flip the pieces so every side gets airflow.
- Skip the oil for most items. Frozen fries, nuggets and similar foods already carry enough oil. A very light spritz can help plain items brown, but it usually isn’t needed.
Frozen food times at 200C/400F
These are common starting points for a standard basket-style air fryer. Times vary by brand, thickness and load, so start checking a couple of minutes early.
| Frozen food | Temp | Time (from frozen) | Shake / turn |
|---|---|---|---|
| Fries / chips | 200C/400F | 12–18 min | Shake at halfway |
| Chicken nuggets | 200C/400F | 8–12 min | Turn at halfway |
| Spring rolls | 200C/400F | 10–15 min | Turn once |
| Fish fingers | 200C/400F | 8–12 min | Turn at halfway |

How to tell when it’s done
Color and crispness are a good first sign, but for anything with meat or fish, temperature is what actually matters. Use an instant-read thermometer in the thickest piece:
- Chicken (nuggets, similar): cook to an internal 74C/165F.
- Fish (fingers, fillets): cook to an internal 63C/145F.
Fries, spring rolls and other non-meat items don’t have a safe internal target — just cook until they’re hot through, golden and crisp to your taste. If a batch looks pale or the centers are still cool, add a couple of minutes and check again rather than cranking the temperature up.
Why your times might differ
If your food comes out under- or over-done compared to the table, a few things are usually behind it:
- Basket size and load. A small basket packed full cooks slower and less evenly. If you cook for one or two and want quick, even results, a right-sized model helps — see the best small air fryer picks.
- No preheat. Starting from cold adds a few minutes and can leave items softer.
- Thicker or larger pieces. Jumbo nuggets or chunky fries need longer than thin-cut versions.
- Model wattage. More powerful units run hotter and faster, so learn how yours behaves and adjust from there.
Related questions
Do you need to defrost food before air frying? No. Most frozen foods are meant to go straight from the freezer into the air fryer. Thawing first often makes coated items soggy and can affect even cooking.
Should you add oil to frozen food? Usually not. Frozen fries, nuggets and similar items are already coated in enough oil to crisp up. A light spritz can help plain, uncoated items brown, but it’s rarely necessary.
Can you stack frozen food in the basket? It’s best not to. A single layer lets the hot air reach every side for even cooking. If you have a lot, cook in batches or shake more often so nothing stays buried.
