Cook frozen fries in an air fryer for about 15 to 20 minutes at 400°F (200°C), shaking the basket once or twice. Fresh-cut fries take 18 to 25 minutes at 375°F (190°C) after soaking and drying. The key to crispy fries in either case is a single layer and a good shake partway through.
Air fryer fries timing
| Fry type | Temp | Time | Notes |
|---|---|---|---|
| Frozen fries | 400°F / 200°C | 15-20 min | Shake twice; no oil needed |
| Fresh-cut fries | 375°F / 190°C | 18-25 min | Soak, dry and toss with a little oil first |
| Sweet potato fries | 380°F / 190°C | 15-20 min | Watch closely near the end; they burn faster |
Thicker cuts and fuller baskets need more time, so check before serving.
How to get crispy fries
For frozen fries:
- Add them straight from the freezer in a single layer.
- Cook at 400°F, shaking the basket every 5 to 7 minutes.
- Add a couple of minutes if they’re not golden yet.
For fresh-cut fries:
- Soak the cut fries in cold water for 30 minutes to remove starch, then dry them thoroughly.
- Toss with a teaspoon of oil so they brown evenly.
- Cook at 375°F, shaking a few times, until golden and crisp.
Why fries turn out soggy
- Overcrowding is the biggest cause. Air can’t circulate through a piled-up basket, so cook in batches.
- Skipping the shake leaves one side pale. Shake or toss a few times.
- Wet fresh fries steam instead of crisping. Dry them well before cooking.

Can I cook a lot of fries at once? Only in a single layer. For bigger batches, cook in rounds or use a larger air fryer with more usable basket space.
