First, read the smoke
Not all smoke means trouble. Most of the time a smoking air fryer is simply burning off grease or oil from a fatty food — harmless and easy to fix. But blue-tinged or burning-plastic smoke is a different story and means stop immediately.
The quick rule: white or light-gray smoke that smells like food or hot oil is usually safe and fixable. Blue, acrid, or plastic-smelling smoke is an electrical warning — unplug the unit and do not use it. The sections below cover both.
Cosori Pro LE Air Fryer, 5-Quart
Only if you have ruled out grease and the smoke is electrical or burning-plastic: stop using it. If it’s past warranty, the Cosori Pro LE is a dependable, roomy replacement — no pressure.
✅ Safe: white grease smoke (and how to stop it)
- You’re cooking something fatty — bacon, sausage, wings, burgers, or well-marbled meat drip grease onto the hot heating element, where it burns off as white smoke. This is the number-one cause and it is not dangerous.
- Add water to the drawer — pour a couple tablespoons of water into the bottom of the outer drawer (not the food basket). It stops the dripping grease from reaching smoking temperature. This is the go-to fix for bacon and burgers.
- Or add a slice of bread — laying a piece of bread under the basket soaks up excess grease and cuts the smoke.
- Lower the temperature — high-fat foods rarely need 400°F. Drop to 350–375°F and the grease is far less likely to smoke.
- Clean out old grease — leftover grease and food bits baked onto the element or drawer from previous cooks will smoke every time. A clean unit smokes far less.
- Don’t overfill with oil — you need only a light spray or toss. Puddled oil pools and smokes.
How to clear grease smoke mid-cook
If white smoke starts while cooking a fatty food, pause and slide the drawer out. Carefully pour off any pooled grease into a heatproof container (never down the drain), add a tablespoon or two of water to the empty outer drawer, and slide it back in to finish. The water raises the effective boiling point at the drawer floor so drippings can’t hit their smoke point.
To prevent it next time, empty and wipe the drawer between batches, cook fatty foods at 350–375°F, and keep the heating element clean. A little smoke from bacon is normal; a smoke-filled kitchen usually just means built-up grease.
🛑 Not safe: blue or burning-plastic smoke
Blue-tinted, sharp, chemical, or burning-plastic smoke is not grease — it points to an electrical fault: overheating wiring, a failing element, melting insulation, or a damaged control board. This is a fire and shock risk.
Stop cooking immediately, turn it off, and unplug it at the wall. Do not keep using it, do not pour water on it, and do not try to open the housing. Let it cool in a ventilated spot away from anything flammable. If there is any flame or it will not stop smoking after unplugging, keep a lid or a Class B/K fire extinguisher handy — never water on an electrical fire — and call for help if needed.
How to tell the two apart fast
- Smell it — food, oil, or “hot cooking” smell points to grease (usually safe). Acrid, chemical, or melting-plastic smell points to electrical (unsafe).
- Look at the color — white or light gray is typically grease. Blue or dark, oily-black plumes suggest something is burning that shouldn’t be.
- Check the food — if you’re cooking bacon or wings, grease is the obvious answer. If you’re cooking something dry or the unit is empty and still smoking, treat it as electrical and unplug.
- Trust the source — smoke from the food basket is usually grease; smoke seeming to come from the motor housing, vents, or cord is an electrical red flag. When unsure, unplug and stop.
Frequently Asked Questions
Is it normal for an air fryer to smoke a little?
Yes — light white smoke when cooking fatty foods like bacon, sausage, or wings is normal. It is grease dripping onto the hot element and burning off. Add a couple tablespoons of water to the outer drawer, lower the temperature to 350–375°F, and keep the unit clean to reduce it. A smoke-filled kitchen usually just means built-up grease that needs cleaning.
How do I stop my air fryer from smoking when cooking bacon?
Pour a couple tablespoons of water into the bottom of the outer drawer (not the food basket) before cooking, or place a slice of bread underneath to absorb dripping grease. Cook bacon at around 350°F rather than 400°F, and empty and wipe the drawer between batches so old grease does not smoke.
When is air fryer smoke dangerous?
When it is blue-tinted, dark, or smells sharp, chemical, or like burning plastic — especially if the unit is empty or cooking something non-fatty. That points to an electrical fault such as overheating wiring or a failing element. Turn it off, unplug it at the wall immediately, and stop using it. Do not pour water on it or open the housing.
My air fryer smokes even when it’s empty. Why?
An empty unit smoking is usually one of two things. If the smoke is white and smells like food, it is leftover grease and crumbs burning off the element — let it cool and clean it thoroughly. If the smoke is blue or smells like plastic or hot electronics, treat it as an electrical problem: unplug it and do not use it.
