Seven minutes at 190°C for inch balls — fast, and minced, so cooked through.
Fresh
Before anything else
From national food-safety authorities, not from us. These take precedence over any cooking time below.
Requirement — Food safety (microbiological)
Minced, reformed and rolled meat — burgers, sausages, meatballs, kebabs, rolled joints — must be cooked through to the centre, not served pink.
Target: 70°C in the thickest part, or an equivalent from the table below.
How to tell, without a thermometer
- No pink in the centre when one is cut open
- Juices run clear
- Steaming hot right through
If it has not got there: Return it to the basket for two or three minutes and check again. Cutting one open to look is a legitimate test and costs you one sausage.
| Temperature | Held for | Measured at |
|---|---|---|
| 70°C | 2 min | the centre of the thickest piece |
| 75°C | 30 sec | the centre of the thickest piece |
The quick answer
190°C (374°F) for 7 min
A single published figure for one-inch meatballs. The chart states a dimension, not a weight.
- Assuming
- about 25mm at the thickest point, 12 pieces, From the fridge
- In
- Dual-basket air fryer
- Loaded
- Single layer, pieces not touching
- Preheat
- Yes, before the food goes in
- Result
- Well done
Preparation
Roll evenly and season. No oil specified.
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 4–4 minutes: Shake the basket
Spheres sit on one point and brown there. Shaking rolls them, and unlike chips they will roll back, so it needs doing more than once on a longer cook.
How to tell it is done
- No pink at the centre of the largest one
- Firm all the way through, not soft in the middle
Where these figures came from — fresh
- Applies to
- Specific to this model
- Why this rating
- Stated as a dimension rather than a weight, which for a sphere is the right variable — heat travels the radius, and the radius is what the reader can measure.

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)
Minced, reformed and rolled meat — burgers, sausages, meatballs, kebabs, rolled joints — must be cooked through to the centre, not served pink.
Target: 70°C in the thickest part.
Stated in full earlier on this page, with how to tell without a thermometer and what to do if it has not got there.
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 5–8 min
Meatball size and whether they are in sauce — a sauced portion takes longer and will not brown.
- Assuming
- 30g per piece, 12 pieces, From the fridge
- In
- Basket air fryer
- Loaded
- Single layer, pieces not touching
- Preheat
- Not needed
- Result
- Heated through
Preparation
Plain meatballs in one layer. Anything in sauce needs an oven-safe dish rather than the bare basket.
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
- Steaming hot right through the middle when one is cut
- The outside has browned again
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 reheat band because a cooked meatball dries out fast. The time is AirfryerHQ's estimate for fridge-cold plain meatballs of this size.
- Last reviewed
- 2026-08-13
What this does not cover
- THE TIME ON THIS RECORD IS NOT SOURCED. Four manufacturers publish a reheating temperature and not one of them names a food, a quantity or a time for a named dish. The temperature here is theirs; 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 4 analysis of published cooking guidance across fifteen manuals

Relied on for: The reading that no manufacturer publishes a reheat time for a named food, and that the time on this record is therefore AirfryerHQ's own estimate.
AirfryerHQ's interpretation of what it says
Citation checked — the document exists and is described correctly
Chilled
No time or temperature for this, and not by accident
Meatballs is sold and cooked chilled, 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)
Minced, reformed and rolled meat — burgers, sausages, meatballs, kebabs, rolled joints — must be cooked through to the centre, not served pink.
Target: 70°C in the thickest part.
Stated in full earlier on this page, with how to tell without a thermometer and what to do if it has not got there.
What we do hold for meatballs: fresh, leftover (reheating). Those are a different question, not a starting point for this one.
From frozen
No time or temperature for this, and not by accident
Meatballs 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.
Same reason as above: a figure adjusted from one we do hold would be indistinguishable from one somebody measured.
What still governs, figure or no figure
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 usually goes wrong
Uneven, because they are round. A sphere in a drawer sits on one point and browns there first, and unlike a chip it does not redistribute itself when the basket is shaken — it rolls back. Shaking still helps, but meatballs need it more often than anything else of a similar size.
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 beef behaves this way
A steak in an air fryer is a compromise: moving hot air browns a surface well but not as fast or as hard as a pan, so the centre gains temperature during the time the crust takes to form. Thickness therefore decides whether air frying is the right tool at all — thick cuts do well, thin ones overcook before they colour.
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 meatballs.
- 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.
