From frozen
Before anything else
From national food-safety authorities, not from us. These take precedence over any cooking time below.
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.
The quick answer
190°C (374°F) for 9–10 min
Prawn size, for a published 280g of sixteen from frozen.
- Assuming
- 280g in total, 16 pieces, From frozen
- In
- Multicooker with air fry
- Loaded
- Single layer, pieces not touching
- Preheat
- Yes, before the food goes in
- Result
- Crisp outside, moist inside
Preparation
Straight from the freezer, spaced apart. No oil is added.
No oil needed.
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 5–5 minutes: Shake the basket
Battered prawns weld to each other and to the basket.
How to tell it is done
- The batter is dry and pale gold
- The prawn has curled tightly inside it
Where these figures came from — from frozen
- Applies to
- Specific to this model
- Why this rating
- A published row with a stated quantity, a stated preparation and an oil quantity, from the manufacturer's own guide for this appliance. Quantity is what makes a chart row checkable against the food in front of a reader, and this chart states one for almost every row.

What this does not cover
- Published by the manufacturer for this appliance. It is evidence about this machine and is not general advice.
- This is a lidded cooking pot rather than a shallow drawer. Depth affects how much fits in one layer, and the quantity in the chart assumes the crisper basket.

What usually goes wrong
Batter that stays pale and greasy. Tempura batter is engineered for oil immersion and has less of the pre-fried surface a breadcrumb coating carries, so it needs the full time at temperature and suffers badly from crowding.
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 prawns behaves this way
Prawn muscle sets at a low temperature and then keeps contracting, squeezing out water and turning the texture rubbery. There is no fat and almost no connective tissue to slow that down. The shape helps a little — a prawn curls as it cooks, which is a visible doneness signal most foods do not give you — and the surface browns readily because of the sugars and proteins in the shell and the residual 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. This measures yours — and it is the single change that fixes most dry frozen tempura prawns.
- 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.
- Why published timings differIf another chart says something else, this is usually why — and which one to believe.
