Can you put aluminum foil in an air fryer?
Yes, you can put aluminum foil in some air fryers if the manual permits it, provided it is secured under food, kept away from heating elements, and does not obstruct airflow.
Research-based article drawn from our 30 countertop ovens & air fryers reviews. Updated September 2026.
Short answer
Yes, aluminum foil can be used in an air fryer if your model’s manual allows it. Use a small piece secured by food, leave room for air to circulate, and keep foil away from heating elements. Never preheat with loose foil inside. Avoid direct contact with acidic foods, and do not line the appliance’s bottom or cover vents.

When aluminum foil is appropriate—and when to skip it
The first step is checking your air fryer’s manual, not cutting a liner. Basket air fryers and countertop air-frying ovens have different layouts, and foil instructions may vary by model, accessory, and cooking mode. Permission to line a baking pan does not necessarily mean you can cover an air-frying basket or crumb tray. If the instructions prohibit foil, follow that restriction.
Where permitted, foil can help contain sticky food and simplify cleanup on an approved cooking surface. It is optional, not a requirement for air frying. For foods that depend on air reaching their undersides, leaving the basket uncovered is generally the better starting point.
Skip foil if you cannot secure it beneath the food or keep it clear of heating elements. Also avoid direct contact between aluminum foil and acidic ingredients such as tomatoes, lemon juice, or vinegar. Use a suitable cooking vessel approved by your manual instead.
How to use foil without blocking airflow
Start with the appliance switched off and cool. Check the manual for approved foil placement and any restrictions on the cooking mode you intend to use. Cut only enough foil for the food or permitted pan area rather than making a wall-to-wall liner.
Keep the foil flat and contained within the approved cooking surface. Do not let edges extend toward the fan or heating elements, and do not wrap the basket or cover its sides. Leave airflow openings unobstructed; if the proposed liner would block them, skip it. Place enough food on the foil to hold it securely throughout cooking.
Never run an empty preheat cycle with loose foil inside. If preheating is required, follow the manual and add the secured foil with the food afterward. Do not line the appliance floor, cover vents, or improvise a drip catcher beneath the basket. After cooking, let the appliance cool before removing foil and cleaning any grease that escaped.
Foil is a cleanup aid, not a shortcut to crispier food
Air frying relies on circulating hot air. Foil placed beneath food interrupts direct airflow through the covered portion of a perforated basket. It can also retain juices around the food. That may be useful for containing a sticky portion, but it works against the dry surface you want on fries or breaded foods.
For crisping, start with an uncovered basket, arrange food in a single layer where practical, and turn or shake it as the recipe and manual direct. Do not use foil to justify crowding the basket. Usable cooking space is smaller than the quoted quart capacity, and flat surface area matters more than the headline volume when food needs space around it.
Foil also does not eliminate cleaning. Grease can still reach the basket, drawer, racks, or interior walls. Remove food residue after use and follow the manual’s cleaning instructions. Never treat a disposable liner as a substitute for keeping the appliance clean.
Three reviewed air fryers that reduce the need for liners
If cleanup is your main reason for using foil, prioritize removable, dishwasher-safe baskets. These three reviewed models offer that convenience, but the supplied review data does not establish their foil policies. Check each model’s manual before using a liner.
The Ninja AF101 Air Fryer has a dishwasher-safe basket and crisper plate. Its round, 4-quart basket limits single-layer cooking area, making it best suited to one or two servings rather than larger meals.
The Chefman Air Fryer 8 Qt offers a dishwasher-safe nonstick basket and more nominal basket volume. Its vertical format still requires mid-cycle shaking for even cooking; the 8-quart label should not be read as eight quarts of usable flat cooking space.
For two separate foods, the Ninja DZ201 Foodi 8 Quart DualZone has two independent 4-quart baskets with separate temperature and timing controls. Both baskets are dishwasher-safe. The trade-off is width within each basket, which restricts wide cuts and larger single items.

Frequently asked
- Can you put aluminum foil in the bottom of an air fryer?
- Do not line the appliance floor or the space beneath the basket with foil. That placement can interfere with airflow and heat management. If your manual permits foil, use it only on the specified cooking surface, secured beneath food, without covering vents or extending toward heating elements.
- Can you preheat an air fryer with foil inside?
- Never preheat with loose foil inside. The fan can lift an unsecured sheet toward the heating element. Follow your manual’s preheating instructions, then add the food and any permitted foil together, with the foil held securely beneath the food and kept clear of airflow openings.
- Is parchment paper better than foil in an air fryer?
- Neither is automatically better. Use only liners your manual permits, and follow the liner’s temperature limit and placement instructions. Parchment must also be secured beneath food and kept away from heating elements. For foods that need maximum airflow underneath, cooking directly in the uncovered basket is generally preferable.
- Can you wrap food completely in foil in an air fryer?
- Only if your manual permits foil packets in the cooking position you plan to use. A sealed packet traps moisture, so expect a steaming effect rather than a crisp exterior. Keep the packet clear of heating elements and vents, and open it carefully after cooking because hot steam can escape.
