Fresh
The quick answer
180°C (356°F) for 16–20 min
Published range for 340–500g on Air Fry 1.
- Assuming
- 340–500g in total
- In
- Combination microwave with air fry
- Published for
- Panasonic Air Fry Combination Microwave Oven NN-CD88QS
- Loaded
- Single layer, pieces not touching
- Preheat
- Not needed
- Result
- Browned but not crisp
Preparation
Season with oil, salt and black pepper, as the chart prints. It gives no amount of oil.
How to load it
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
- Shrunken by about half and browned at the edges
- No pool of liquid
Where these figures came from — fresh
- Applies to
- Specific to this model
- Why this rating
- Three to four times the drawer machine's five minutes. Mushrooms release a great deal of water and a large cavity carries it away more slowly, which is a plausible reason and not a demonstrated one.

Leftover (reheating)
No time or temperature for this, and not by accident
Leftover (reheating) is a real question for mushroom slices. 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 mushroom slices: fresh. That is a different question, not a starting point for this one.
Manufacturer figures with no state given
Each of these is a published figure for one named machine. The manufacturer does not say whether this is fresh or frozen. So they are kept apart from the figures above, and not used as the answer for any of them.
Cookworks 9L Dual Air Fryer: 200°C for 5 min
A single published figure for half-inch slices.
Ninja Foodi MAX Health Grill & Air Fryer AG551UK: 200°C for 10 min
A single published figure of ten minutes for 700g cut in quarters, not a range.
Questions people ask about mushroom slices
- Why do my mushrooms come out grey and wet?
- There were too many in the basket. Mushrooms give up a great deal of water, and a crowded basket makes more of it than the airflow can carry away, so they stew in it. Half the quantity is the fix, and it is the whole of the fix: no setting rescues an overfilled basket of mushrooms.A general cooking principle, not a measurement.
- How thick should I cut mushrooms for an air fryer?
- The charts here do not agree on the cut, which is part of why their times differ. One is for half-inch slices, one for quartered mushrooms, and one does not say. Thicker pieces take longer and keep their shape; thin slices are done quickly and shrink to very little. Decide the cut first and follow the row that matches it.From the figures on this page.
What usually goes wrong
Grey and swimming. A crowded basket of mushrooms produces more water than the airflow can remove, and they stew instead of browning. Half the quantity in the same basket is not a compromise here — it is the difference between the dish working and not.
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.
Mushrooms in fast-moving hot air
A mushroom is a sponge of around ninety per cent water held in a protein structure that contracts sharply when heated. In moving air it expels that water fast, and if the air can carry it away the mushroom browns and concentrates; if it cannot, the mushroom sits and boils in its own liquid. That is the whole difference between a good air-fried mushroom and a grey one, and it is decided by how many are in the basket rather than by time or temperature.
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.
- 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
What tends to go wrong with mushroom slices, each with the fastest thing to check first.
- Steam pouring out of the air fryer — Water leaving food, which is what the appliance is for. It only matters because steam and smoke look similar and mean very different things.
