Here's How To Prevent Your Air Fryer From Smoking From Greasy Foods
If your air fryer has cooked a lot of fried foods that might be on the greasy side, it might start smoking. Besides cleaning it between uses, there are some ways to prevent smoke.
To stop an air fryer from smoking right away, add a couple of tablespoons of water to the bottom, where it will convert to steam and prevent smoke.
If you're cooking something that's known to have a lot of grease, opt for the bread method. Put a slice at the bottom to absorb grease, preventing smoke in the first place.
