How long to cook chestnuts in an air fryer?
Cook chestnuts in an air fryer at 200°C / 400°F for 12–18 minutes, shaking once halfway, until the scored shells open and the nut inside is tender.
Air fryer chestnuts are fastest when scored and cooked hot, with doneness judged by opened shells and tender centers rather than an internal temperature. The main timing range is 12–18 minutes at 200°C, with small chestnuts finishing earlier and large batches needing a little longer.
Time & temperature chart
| Size / cut | Temp | Time | Tip |
|---|---|---|---|
| Small to medium chestnuts, scored | 200°C | 9–12 min | Start checking at 9 min; shells should open at the cuts. |
| Medium to large chestnuts, scored | 200°C | 12–18 min | Best default range; shake halfway for even roasting. |
| Mixed-size or fuller basket | 200°C | 15–20 min | Keep as close to a single layer as possible; check large nut |
| Gentler roast | 175°C | 15–18 min | Use when shells brown too fast before the centers soften. |
Times are a guide — air fryers vary by 10–20%. Always cook to the safe internal temperature, not just the timer.
How to air fry chestnuts
- 1
Rinse the chestnuts and discard any that are moldy, shriveled, or have holes.
- 2
Score every chestnut before air frying: cut a clear X or long slit through the shell on the rounded side so steam can escape.
- 3
Optional but helpful: soak the scored chestnuts in hot water for 5–15 minutes, then drain and pat dry. This can make them easier to peel.
- 4
Preheat the air fryer to 200°C if your model requires it.
- 5
Place the chestnuts in the basket in a single layer or as close to one layer as possible.
- 6
Air fry at 200°C for 12–18 minutes, shaking halfway. Small chestnuts may be ready at 9–12 minutes; large or crowded batches may need up to 20 minutes.
- 7
Check doneness by looking for opened cuts, lifted shell edges, and tender flesh inside. Add 2–3 minutes if the centers are still firm.
- 8
Tip the hot chestnuts into a clean towel, wrap loosely, and rest for 3–5 minutes. Peel while warm.
Pro tips
- Do not skip scoring. Unscored chestnuts can burst as steam builds inside the shell.
- Use a small sharp knife and cut through the outer shell and inner skin, but avoid cutting deeply into the nut.
- Peel chestnuts while they are still warm; the shells and inner skins tighten as they cool.
- If some chestnuts are much larger than others, remove the small ones when done and keep cooking the larger ones for a few more minutes.
- For a crowded basket, shake more than once and expect the upper end of the time range.
Frequently asked questions
Do you have to score chestnuts before air frying?
Yes. Score every chestnut with an X or slit before air frying so steam can escape and the shell opens for peeling.
What temperature is best for air fryer chestnuts?
200°C / 400°F is the best default temperature for roasted chestnuts. Use 175°C / 350°F if your air fryer browns the shells too quickly.
Should I soak chestnuts before air frying?
Soaking is optional. A 5–15 minute hot-water soak can help with peeling and moisture, but scored chestnuts can still be air fried without a long soak.
How do I know when air fryer chestnuts are done?
They are done when the scored cuts have opened, the shell edges lift back, and the chestnut inside is tender when pierced or tasted.
Why are my air fryer chestnuts hard to peel?
They may be undercooked, not scored deeply enough through the inner skin, or left to cool too long. Cook a few minutes more if needed and peel while warm.
