Yes—but carefully. Aluminum foil can be used in an air fryer, but there are important rules to follow:

• Check your manual first—some air fryers don’t allow foil.
• Don’t block airflow—never cover the basket completely.
• Keep foil secure—loose foil can damage the fan or cause a fire.
• Avoid the heating element entirely.

When to use foil: It’s great for moist or sticky foods like fish or veggies.
When to avoid it: Skip it for crispy foods like fries—it can trap moisture and reduce crunch.

Alternatives:

• Silicone liners – reusable and eco-friendly.
• Parchment paper – convenient and disposable.

Bottom line: Foil is fine if used properly. Always follow your air fryer’s guidelines for safe, delicious results.
