What this does not cover
- Published by the manufacturer for this model. It is evidence about this appliance and is not general advice.
- The chart heads this row hand-cut and prints no other word about state. It is held as fresh on that word, which is the chart's and not AirfryerHQ's.
- The row says sweet potato fries. It is held with sweet potato wedges, the page AirfryerHQ keeps for sweet potato cut into fries or wedges.

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
170°C (338°F) for 5–8 min
Wedge thickness and quantity.
- Assuming
- 350g in total, From the fridge
- In
- Basket air fryer
- Whose figure
- AirfryerHQ's own, not one manufacturer's chart
- Loaded
- Single layer, pieces not touching
- Preheat
- Not needed
- Result
- Heated through
Preparation
Spread out in one layer. 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
- The edges are dry and firm again
- 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
- Ten degrees below the potato figure because sweet potato's sugars darken on a second heating. The time is AirfryerHQ's estimate.
- Last reviewed
- 2026-08-13
What this does not cover
- THE TIME GIVEN HERE 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 analysis of published manufacturer cooking and reheating guidance
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 given here is AirfryerHQ's estimate.
AirfryerHQ's interpretation of what it says
Citation checked — the document exists and is described correctly
From frozen
No time or temperature for this, and not by accident
From frozen is a real question for sweet potato wedges. AirfryerHQ holds no published figure for it: not one of the manufacturer manuals read for this catalogue gives a chart row for this food in this state.
We are not going to produce one by adjusting the fresh figure above. A time arrived at that way would appear on this page looking exactly like a time somebody measured, and you would have no way to tell the difference.
What still governs, figure or no figure
These rules come from national food-safety authorities and apply whether or not anybody has published a cooking time. They are the part of this question we can answer.
Requirement — Food safety (microbiological)
Food cooked from frozen must reach the same core temperature as the same food cooked fresh — the frozen centre is the last thing to get there.
Target: 70°C in the thickest part.
How to tell, without a thermometer
- No ice or cold spot at the centre when the thickest piece is cut open
- Steaming hot throughout, tested in the middle rather than the edge
If it has not got there: Reduce the temperature by 10–20°C and give it longer. A lower set point lets the centre catch up before the surface passes the point of no return, and it is the single most useful adjustment for cooking from frozen.
Important: If the packaging says the product must be thawed before cooking, follow it. That instruction exists because the manufacturer has tested cooking it from frozen and it did not reach temperature reliably.
What we do hold for sweet potato wedges: fresh, leftover (reheating). Those are a different question, not a starting point for this one.
Manufacturer figures with no state given
This is a published figure for one named machine. The manufacturer does not say whether this is fresh or frozen. So it is kept apart from the figures above, and not used as the answer for any of them.
Russell Hobbs SatisFry Air Fryer & Grill Multi Cooker 5.5L: 200°C for 15–20 min
Published range, identical to the same chart's figure for ordinary potato wedges. The manufacturer treats them as the same cook; the result is not the same.
Questions people ask about sweet potato wedges
- Why will sweet potato wedges not go as crisp as chips?
- They have the sugar to brown and not the fine surface starch that makes a potato chip crust. Past the point where they are tender, extra time only blackens the thin edges. Take them out when they are soft and coloured, and stop chasing a crunch they are not built to give.A general cooking principle, not a measurement.
- Do sweet potato wedges need oil?
- Both manufacturers' rows on this page use it. One says to rinse and dry the wedges and toss them in oil with salt and pepper; the other gives one tablespoon for hand-cut sweet potato. Neither soaks them.From the figures on this page.
What usually goes wrong
Burnt tips over a soft middle, chased by somebody trying to get them crisp. Sweet potato has the sugar to caramelise and not the fine surface starch to form a crust, so extra time past the point of tenderness only blackens the thin edges. It is a different food from a chip and the honest advice is to stop earlier.
Running the appliance safely
The rules for the machine are the same whatever is in it: plug it straight into a wall socket, leave clear space round it, do not overfill it, do not leave it running unattended, and unplug it at black smoke or an electrical smell. They are set out once, each with its source and what to do if it has already happened, and not repeated on every food. Every rule for running an air fryer safely.
One of them is about this food and not the machine: Aim for a golden yellow colour or lighter on starchy foods such as chips and roast potatoes, rather than a darker brown.
Sweet potato in fast-moving hot air
Sweet potato carries far more sugar and far less of the fine surface starch that makes a chip crisp. The sugar caramelises and then burns at temperatures a regular chip is perfectly happy at, which is why the published whole-roast figure is 190°C where a jacket potato is 200°C. The flesh also holds more water and less structure, so wedges soften rather than developing the fluffy interior a floury potato gives. A sweet-potato chip that is genuinely crisp is difficult and usually involves a coating.
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. A probe measures yours, which is what the safety rule on this page asks for.
- 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.
- Cooking from frozenUsually cooler and longer than the same food fresh, and never worked out from the fresh figure.
- 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.
