How to Stop an Air Fryer from Smoking
Updated 7 September 2026
If your air fryer is smoking, the usual causes are grease buildup, too much fat collecting below the basket or sugary marinades burning on hot surfaces.
Quick answer
- 1Clean the basket, drawer and heating element thoroughly.
- 2Pour off excess fat during cooking when making bacon or other fatty foods.
- 3Lower the temperature slightly for sugary glazes and marinades.
Grease is the main cause
Old grease splatters on the heating element or drawer are one of the most common reasons an air fryer smokes. A quick wipe after each use and a deeper clean every week prevents this.
Fatty foods need extra care
Foods like bacon, sausages and chicken wings can release a lot of fat. Emptying the drawer carefully during cooking or adding a little water under the basket can help reduce smoke.
Frequently Asked Questions

Rendered fat pooling in the drawer is usually the reason. Pour it off partway through cooking or add a little water below the basket if your model allows.
Does smoking mean my air fryer is broken?+
Usually not. It is most often a cleaning or grease-management issue rather than a fault.
