Air fryer owners are being advised to avoid a common mistake that experts say could increase the risk of house fires. With air fryers now a staple in millions of kitchens, safety guidance has become increasingly important. While the appliances are widely used for quick, low-oil cooking, specialists warn that incorrect use of liners such as parchment paper and foil can create hidden dangers.
Manufacturer Warnings
Manufacturers, including SharkNinja, say many users are unknowingly making a mistake that can restrict airflow inside the appliance and, in some cases, increase the risk of fire. In guidance issued to customers, the company warned against wrapping food fully in parchment paper or aluminium foil.
“Whilst it's safe to use parchment paper and aluminium foil in your air fryer, completely covering or wrapping your food in them can block the airflow in your air fryer and if not secured properly, can increase the risk of fires if the paper or foil comes in contact with the heating element.”
Proper Usage Tips
It added: “When using parchment paper or aluminium foil, it is essential to ensure the paper or foil is placed underneath the food, or grill plate, as the weight of the food helps keep it in place and prevents it from lifting during cooking.”
Retailer Currys also advises caution over the type of foil used. It recommends heavy-duty foil over thinner varieties, which can tear or shift during cooking. Experts said foil should be trimmed to fit neatly inside the basket, warning: “You don't want it to be too large though, as any excess foil can block the airflow and ruin the cooking performance.” Once cooking is complete, users are advised to remove food promptly to prevent moisture build-up or residue sticking to the basket.
When Foil Should Not Be Used
Safety experts say there are situations where foil is best avoided altogether. Foods that release high levels of fat, such as bacon, can make the foil slippery and greasy, leading to uneven cooking or food sticking. Foil is also not recommended for use in air fryers with non-stick coatings, as it may scratch or damage the surface over time.
As an alternative, experts suggest silicone mats, which are heat-resistant, reusable and easier to clean. They also help catch spills and keep the appliance cleaner during cooking.
With air fryers continuing to grow in popularity, safety experts are urging users to follow manufacturer guidance closely to avoid accidents and keep appliances working safely and efficiently.
