Honestly? Go for it, but be a little thoughtful. Foil is your air fryer’s cool assistant—not its boss. Use it for easy cleanup, wrapping veggies, or catching drips. Just leave enough room for the hot air to whoosh around like it wants to.
Next time you’re staring at a roll of foil and a bag of frozen onion rings, you’ll know: yes, you can put foil in an air fryer. Just don't block the breeze, don't let it touch the heater, and you’ll be eating crispy, foil-assisted perfection in minutes. How awesome is that?
