Fresh
The quick answer
180°C (356°F) for 18–35 min
Published range for 200–1400g of 10x10mm home-cut fries, soaked and oiled.
- Assuming
- 700g in total, about 10mm at the thickest point, At room temperature
- In
- Basket air fryer
- Loaded
- Heaped, shaken during cooking
- Preheat
- Not needed
- Result
- Crisp outside, moist inside
Preparation
Cut to 10x10mm, soak for 30 minutes in water, dry thoroughly, then add a quarter to one tablespoon of oil — all four steps are the manufacturer's, and the soak is the one most often skipped.
About 10ml of oil.
How to load the basket
Heaped, shaken during cooking. Substantially slower and uneven unless shaken. Surfaces buried in the pile steam rather than crisp.
While it cooks
At about 9–18 minutes: Shake the basket
The chart marks this row as requiring shaking.
How to tell it is done
- Golden yellow
- A crisp shell over a floury interior
In a different appliance
Countertop oven with air fry: 200°C for 40 min
A single published figure for 700–750g of 8mm × 8mm home-cut fries with a tablespoon of oil, with shaking. Forty minutes, against 25–30 for the same weight of frozen chips in the same chart.
Multicooker with air fry: 200°C for 25 min
A single published figure with the instruction to rinse, dry and toss in salt, pepper and oil. Fifteen minutes shorter than another manufacturer's figure for the same food.
Oven-style air fryer: 200°C for 35–40 min
Published range for 500–700g of hand-cut chunky fries in the basket, with a tablespoon of oil.
Multicooker with air fry: 200°C for 18–22 min
How dry the chips were going in. The chart's own footnote is emphatic that the drier the chips, the better the result, and that is what moves this range.
Basket air fryer: 200°C for 10–16 min
Quantity within the published 100-400g band, for chips cut at 8x8mm.
Basket air fryer: 180°C for 18–26 min
Quantity within the published 200-500g band, for 10x10mm hand-cut fries.
Basket air fryer: 180°C for 22–27 min
Quantity within the published 300-800g band, for 8x8mm hand-cut fries.
Dual-basket air fryer: 180°C for 40 min
A single published figure of forty minutes for 500g in DRAWER 1, not a range. Drawer 2 takes 200g in thirty-five minutes.
Where these figures came from — fresh
- Applies to
- Specific to this model
- Why this rating
- The soak instruction is what makes this row the most useful home-cut chip figure in the catalogue. The 25-to-40-minute disagreement across other manufacturers is largely about whether they assume this step, and this is the only chart that states it with a duration.

Leftover (reheating)
Before anything else
From national food-safety authorities, not from us. These take precedence over any cooking time below.
Requirement — Food safety (microbiological)
Cool cooked food and get it into the fridge within one to two hours, keep the fridge between 0 and 5°C, and eat leftovers within 48 hours.
How to tell, without a thermometer
- There is no sensory test for this rule, and that is the point: food held too long at the wrong temperature does not necessarily look, smell or taste different
If it has not got there: Throw it away. This is the one rule in this catalogue where the remedy is not 'cook it longer', because cooking does not reverse it.
Important: Cooked rice is the sharpest case: Bacillus cereus toxins form at room temperature and survive reheating. Rice left out for more than an hour goes in the bin.
Requirement — Food safety (microbiological)
Reheat leftovers until steaming hot all the way through, and only reheat them once.
Target: 70°C in the thickest part, or an equivalent from the table below.
How to tell, without a thermometer
- Steam rising from the centre, not just the edges
- The middle is hot to the touch, tested after removing it from the appliance
If it has not got there: Keep going, and break dense food up or spread it out so the heat can reach the middle. If it will not heat through evenly, a microwave to get the centre hot followed by the air fryer to crisp the surface is a better tool for the job than the air fryer alone.
Important: Cooked rice and pasta left at room temperature can develop Bacillus cereus toxins that reheating does not destroy. If cooked rice has been out of the fridge for more than an hour, discard it rather than reheating it.
| Temperature | Held for | Measured at |
|---|---|---|
| 70°C | 2 min | the centre of the food |
| 75°C | 30 sec | the centre of the food |
The quick answer
180°C (356°F) for 3–6 min
Quantity, and how damp they were in the fridge.
- Assuming
- 250g in total, From the fridge
- In
- Basket air fryer
- Loaded
- Single layer, pieces not touching
- Preheat
- Not needed
- Result
- Heated through
Preparation
Spread out in one layer, patted dry if they are damp. Nothing added.
How to load the basket
Single layer, pieces not touching. The reference condition. Air reaches every surface, and times are the shortest the food will achieve.
How to tell it is done
- Rigid again rather than bending
- Steaming hot right through the middle, not just at the edges
Change the result
Each of these moves the outcome in a known direction, and most cost you something. The trade is stated so you can decide whether you want it.
- To be sure it is safe rather than just warm
- Go by the food and not the clock. It has to be steaming hot the whole way through, and the middle of a dense portion lags a long way behind its surface in an air fryer.
Where these figures came from — leftover (reheating)
- Applies to
- Specific to this type of appliance
- Why this rating
- The top of the published reheat band, because re-crisping a chip is about driving surface water off fast rather than heating a centre. The time is AirfryerHQ's estimate.
- Last reviewed
- 2026-08-13
What this does not cover
- THE TIME ON THIS RECORD IS NOT SOURCED. Five manufacturers publish a reheating temperature and not one names a food, a quantity or a time for a named dish. The temperature sits inside their band; the time is AirfryerHQ's estimate and has not been measured.
- Reheating is governed by the food-safety rule above rather than by this figure. Steaming hot throughout is the requirement; the time is a guide to getting there.

AirfryerHQ Sprint 5 analysis of published guidance across twenty-one manuals
AirfryerHQ — Calculated or inferred by AirfryerHQ (United Kingdom)
Relied on for: The reading that six published reheating positions across five manufacturers span 150-180°C, that three cap the time at ten minutes, and that none names a food — so the time on this record is AirfryerHQ's estimate.
AirfryerHQ's interpretation of what it says
Citation checked — the document exists and is described correctly
What usually goes wrong
Soggy, or leathery. A raw chip has to lose surface water, gelatinise its starch and then dehydrate that surface into a crust, and a crowded basket stops all three by filling the chamber with steam. The manufacturers who publish forty minutes are cooking chips that were not soaked or parboiled; the one who publishes twenty-five assumes they were. That assumption is never stated on the chart and it is most of the difference.
Running the appliance safely
These apply to every food and every air fryer, so they are here once rather than repeated under each state above. They come from Electrical Safety First, from UK product-safety notices and from the manufacturers’ own manuals.
- Plug an air fryer directly into a wall socket. Do not run one from an extension lead.
- An unusual smell, an unusual noise, or scorch marks on the plug mean stop using it and contact the manufacturer.
- Do not overfill. Food touching the heating element is a fire risk, not a cooking problem.
- White smoke from fatty food is usually normal. Black smoke means unplug it immediately.
- Do not leave an air fryer running unattended.
- Leave clear space above and around the appliance, and never cover the air intake or the outlet.
- Aim for a golden yellow colour or lighter on starchy foods such as chips and roast potatoes, rather than a darker brown.
- Buy from a reputable retailer rather than a third-party marketplace seller.
- Clean the drawer, the plate and the element after use. Accumulated grease is what smokes, and then what burns.
- Register the appliance with its manufacturer. It is how a recall reaches you.
- Do not rely on the appliance's own thermal protection. A UK recall was issued because it did not operate.
Each links to its own page, with what it means in practice, what to do if it has already happened, and the source it comes from. Every safety rule AirfryerHQ holds.
Why potato behaves this way
A potato is mostly water held in a starch matrix. Heat gelatinises the starch and drives water out of the surface layer; when that dehydrated layer is thin, dry and hot enough it becomes crisp. The whole game is getting water away from the surface faster than it arrives from inside, which is why crowding a basket produces soggy chips — the escaping steam has nowhere to go and condenses back onto the food. Sugar content decides browning speed, which is why some potatoes darken far faster than others at the same setting.
Where to go from here
The pages that answer the questions this one tends to raise.
- Using a thermometer, and where to put itThe times above are for a piece that is not the one you are holding. This measures yours — and it is the single change that fixes most dry homemade chips.
- How food actually gets crispyWhy patting it dry, spacing it out and a little oil are all the same instruction — so you can apply it when a page runs out.
- Reheating leftoversA different question governed by a different rule — steaming hot throughout, and only once.
- Why published timings differIf another chart says something else, this is usually why — and which one to believe.
If it went wrong
The ways homemade chips specifically tends to fail, each with the fastest thing to check first.
- Food is not crisping — Almost always moisture that cannot get out, and almost always because there is too much in the basket. One manufacturer says so directly.
