Seven to nine minutes fresh — the same as a beef burger, and for different reasons.
Chilled
The quick answer
250°C (482°F) for 7–9 min
Patty thickness, for four published 125g burgers. The same figure the same chart gives a beef burger of the same weight, which is worth noticing.
- Assuming
- 125g per piece, about 20mm at the thickest point, 4 pieces, From the fridge
- In
- Multicooker with air fry
- Loaded
- Single layer, pieces not touching
- Preheat
- Yes, before the food goes in
- Result
- Heated through
Preparation
Seasoned and laid flat on a hot plate, not pressed down.
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.
While it cooks
At about 4–5 minutes: Turn the pieces over
The published instruction says to flip halfway if desired. Only the face on the plate takes a crust, and a plant-based patty browns less readily than beef.
How to tell it is done
- A dark crust where the patty met the plate
- Firm right through with no soft, cool centre
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.
- More colour
- Brush the surface lightly with oil before it goes on. There is less fat here to brown with.
Where these figures came from — chilled
- Applies to
- Specific to this model
- Why this rating
- A published row with a stated quantity and thickness, charted in its own block rather than borrowed from the beef row — which is the useful part: the manufacturer treated these as their own food and arrived at the same number anyway.

What this does not cover
- Published by the manufacturer for this appliance. It is evidence about this machine and is not general advice.
- Plant-based burgers differ enormously between brands in fat, binder and water. The packet is a better source where it gives one.

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
160°C (320°F) for 3–6 min
Patty thickness.
- Assuming
- 125g per piece, about 20mm at the thickest point, 2 pieces, From the fridge
- In
- Basket air fryer
- Loaded
- Single layer, pieces not touching
- Preheat
- Not needed
- Result
- Heated through
Preparation
Patty alone, bun kept out, in one layer.
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.
While it cooks
At about 2–3 minutes: Turn the pieces over
A flat patty against the basket heats from one side only.
How to tell it is done
- Steaming hot right through the middle, not just at the edges
- The surface has dried rather than sweating
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
- Low in the published band. There is no fat continuing to render, so extra time only dries it. 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
From frozen
No time or temperature for this, and not by accident
Vegan burgers is sold and cooked from frozen, so the question is a real one. 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 chilled 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 vegan burgers: chilled, leftover (reheating). Those are a different question, not a starting point for this one.
What usually goes wrong
Dry and dense, from treating extra time as a safety margin. There is no connective tissue to break down and no fat to render, so every minute past the published window only removes water.
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 vegan meat alternatives behaves this way
These products are protein isolates, starches and fats bound with methylcellulose or a similar hydrocolloid, and the binder is what governs their behaviour. It sets on heating and holds the shape, which is why they need no resting and tolerate a shorter cook than the meat equivalent — the published frozen vegan sausage time is eight minutes against nine to twelve for a frozen pork one. There is no fat to render and no connective tissue to break down, so extra time buys nothing at all and simply dries them; and because the added fat is usually coconut or rapeseed rather than animal fat, it liquefies at a lower temperature and leaves earlier.
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 vegan burgers.
- 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.
Easily confused with
- Beef burger — A different cooking problem with a different answer.
