Fresh
The quick answer
200°C (392°F) for 15 min
A single published figure for inch-and-a-half cubes — a notably larger cut than the chart's other vegetables.
- Assuming
- 400g in total, about 38mm at the thickest point, At room temperature
- In
- Dual-basket air fryer
- Loaded
- Single layer, pieces not touching
- Preheat
- Yes, before the food goes in
- Result
- Crisp outside, moist inside
Preparation
Cut generously large and toss in oil. Far less oil is needed than in a pan, which is the main reason to cook aubergine this way at all.
About 15ml of oil.
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 8–8 minutes: Shake the basket
Cubes brown on whichever face they rest on.
How to tell it is done
- Golden browned faces
- The interior has gone creamy and collapsed — if it squeaks against the teeth it is undercooked
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.
- Certainty it is cooked
- Take it to the full time and then some. Undercooked aubergine is unpleasant in a way overcooked aubergine is not.
In a different appliance
Multicooker with air fry: 260°C for 8–10 min
Piece size, for a published 500g cut into 5cm pieces and brushed with oil.
Where these figures came from — fresh
- Applies to
- Specific to this model
- Why this rating
- The large stated cut is deliberate — small aubergine cubes collapse before they brown — and it is the sort of detail a chart row communicates well and prose usually loses.

What this does not cover
- Published by the manufacturer for this model. It is evidence about this appliance and is not general advice.
- A single published figure rather than a range. AirfryerHQ has not invented a tolerance around it.

Leftover (reheating)
No time or temperature for this, and not by accident
Aubergine cubes is sold and cooked leftover (reheating), 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 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)
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 |
What we do hold for aubergine cubes: fresh. Those are a different question, not a starting point for this one.
What usually goes wrong
Squeaky and bitter, which is the specific signature of undercooked aubergine. Its spongy structure has to collapse fully before the texture becomes creamy, and stopping at the point where it looks browned is stopping too early. This is a vegetable to take to the top of the range.
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 aubergine behaves this way
Raw aubergine flesh is a porous, air-filled structure — closer to a sponge than to a solid — and that structure is why it soaks up oil in a pan. In hot moving air the air pockets collapse under heat rather than filling with fat, and the flesh goes creamy while the cut faces brown. The skin is tough and stays that way. Undercooked aubergine is unpleasant in a specific way — squeaky and bitter — so this is a vegetable where the longer end of the range is usually the right one.
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 aubergine cubes.
- 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.
