An air fryer should last for years. Yet many baskets start sticking, peeling or smoking after a few months, and the cause is almost always the same everyday habit. Most people do it out of reflex, convinced it protects the appliance. In reality, it slowly ruins the nonstick coating.
The habit: aerosol cooking spray
Spraying the basket with a can of nonstick cooking spray seems like the obvious way to keep food from sticking. The problem is what is in the can. Many aerosol sprays contain lecithin, an emulsifier, along with propellants and anti-foaming agents.
At high heat, lecithin does not burn off cleanly. It bakes onto the surface and builds a sticky, gummy layer that ordinary washing does not remove. As Tasting Table explains, that residue covers the nonstick surface and, over time, makes food stick more, not less. Scrubbing it off then scratches the coating, and the basket starts to peel.
The irony is that the coating is designed to work with very little fat. Most modern baskets release food fine with a light film of oil, and the extra layer of spray mostly ends up as residue. Many manufacturers’ manuals now say it plainly: do not use aerosol cooking sprays on the basket.
How to tell if it has already happened
- A tacky, brownish film on the basket that stays after washing.
- Food that sticks even though you oil it.
- White smoke or a burnt smell at the start of cooking.
- Small chips or flakes in the coating.
What to do instead
- Oil the food, not the basket. Toss vegetables or fries with a teaspoon of oil in a bowl before cooking.
- Use a refillable oil mister or a brush with a plain oil: avocado, canola, peanut or sunflower oil handle high heat well.
- Skip the oil completely for foods that already contain fat, like chicken thighs, bacon or frozen breaded foods.
- Clean after each use with warm soapy water and a soft sponge, never steel wool. For baked-on residue, soak the basket in hot water with a little dish soap before wiping.
A few drops of water in the drawer under the basket also keep dripping fat from smoking.
If your basket is already sticky, a paste of baking soda and a little water, left for 15 minutes and wiped with a soft sponge, removes most of the gummy layer without scratching. Repeat rather than scrubbing harder.
Two more habits that shorten its life
Pushing the appliance against the wall or under a cabinet blocks the vent at the back, which makes it overheat. Leave a few inches of clearance on every side. And plug it straight into a wall outlet: like every heating appliance, an air fryer does not belong on a power strip, as electricians explain in this guide.
The air fryer itself is evolving fast, as we saw in goodbye to the classic air fryer, and its crumbs belong to one of the dirtiest spots in the kitchen.
Oil the food, not the basket, and put the spray can away. That’s the trick.
