Air fryers might seem like crisping microwaves, but the rules aren’t the same when it comes to foil. Here’s why you can—and sometimes should—put foil in your air fryer.
Many home cooks love air fryers for their ability to crisp up foods like chicken wings, fries, and fish without the mess and extra oil of deep frying. Naturally, the idea of using aluminum foil to make cleanup even easier is tempting. After all, foil is a kitchen staple for baking, grilling, and roasting in traditional ovens, so why not in an air fryer? The good news is, yes, aluminum foil can be used safely in most air fryers, but there are specific guidelines to follow to ensure safety, optimal cooking, and to avoid damaging your appliance. Let’s dive into how to use it properly, when it’s a great idea, and when you might want to skip it.
Is Aluminum Foil Safe for Air Fryers?
Absolutely, aluminum foil is generally safe to use in an air fryer, but it’s not as simple as tossing it in like you would in a regular oven. Air fryers work by circulating hot air rapidly around food, often at temperatures reaching 400°F or higher, to create that crispy, fried texture. Unlike microwaves, where foil can cause sparks and fires due to electromagnetic waves, air fryers rely on convection heat, making foil a safe option if used correctly. The key is to avoid any contact with the heating element, typically located at the top of the air fryer, and to ensure the foil doesn’t disrupt the airflow that’s crucial for even cooking. Check your air fryer’s manual first—some manufacturers may advise against foil for specific models, and it’s always best to follow their guidance.
How to Use Aluminum Foil in an Air Fryer Safely
To get the most out of foil without risking your appliance or your meal, follow these practical tips. First, only place foil in the basket, not the drawer or the bottom of the air fryer itself. Lining the entire base of the appliance can block air vents, trap heat, and potentially overheat the unit. Instead, cut a piece of foil to fit just the bottom of the basket, leaving space around the edges for air to flow freely. Next, always weigh the foil down with food. The powerful fan in an air fryer can lift loose foil, and if it touches the heating element, it could cause damage or even a fire hazard. For example, when cooking bacon or sausages, place the foil under the food and ensure the pieces hold it securely in place.
Another handy trick is to create a foil “sling” for delicate items. Fold two strips of foil in half to make them sturdier, then lay them in a cross pattern in the basket. Place your food—like fish fillets or a small batch of veggies—in the center, and tuck the ends of the strips down during cooking to keep them from flapping. When done, use the strips as handles to lift the food out easily. This method works wonders for items that might stick or fall apart, like a cheesy chicken breast or a fragile piece of salmon, and it cuts down on scrubbing time.
When to Use Aluminum Foil
Foil shines in certain air fryer scenarios. For sticky or saucy foods, like marinated chicken wings or BBQ ribs, lining the basket with foil catches drips and prevents burnt-on messes that are tough to clean. It’s also a lifesaver for crumbly foods—think breaded mozzarella sticks, onion rings, or homemade chicken nuggets—where loose crumbs might fall through the basket’s holes and burn. If you’re reheating leftovers already wrapped in foil from the fridge, you can pop them straight into the air fryer for a quick, no-fuss warm-up. Foil is also great for small, lightweight items like eggs or chickpeas that might roll around or slip through the basket’s perforations.

When to Skip Aluminum Foil
Not every situation calls for foil, and sometimes it’s better to go without. The air fryer’s magic comes from that hot air circulating all around the food, especially through the perforated basket, to crisp up the bottom and sides. Covering the basket completely with foil blocks this airflow, which can lead to uneven cooking or a soggy bottom—nobody wants that on their fries or fried chicken! For foods where crispiness is key, like vegetables, potato wedges, or breaded cutlets, cook directly on the basket to let the air do its job. Also, avoid foil with acidic foods, such as tomatoes, citrus fruits, or anything marinated in vinegar or lemon juice. The acid can react with the aluminum, breaking it down and potentially leaching small amounts into your food, which might affect taste or raise health concerns over time. In these cases, opt for parchment paper, which is non-reactive and widely available—look for perforated air fryer-specific sheets at stores or online, like those suggested by Eating Well.
Alternatives to Aluminum Foil
If foil isn’t the right fit, you’ve got options. Parchment paper is a fantastic alternative, especially for acidic dishes or lighter foods. It’s naturally nonstick, so you don’t need to grease it, and it’s heat-resistant up to high temperatures, though you should still weigh it down with food to keep it from flying into the heating element. Never use wax paper, as its coating can melt and create a mess or fire risk. Silicone liners are another reusable choice—durable, food-safe, and easy to clean, they’re perfect for frequent air fryer users. You can find these at retailers like Amazon or even in guides from KitchenAid. If cleanup is your main worry, consider a modern air fryer with a dishwasher-safe basket or a self-cleaning mode to skip liners altogether.
Cleaning and Maintenance Tips
Using foil can reduce mess, but it’s not a total fix. After cooking, let the basket and any foil cool completely before handling. Carefully fold the foil inward to trap crumbs and grease, then toss it. Wash the basket by hand with warm, soapy water or check your manual to see if it’s dishwasher-safe. Regular cleaning—every few uses—keeps your air fryer in top shape, preventing grease buildup or lingering odors. Avoid abrasive scrubbers that might scratch nonstick coatings, and never submerge the main unit in water, as it houses electrical components. A quick wipe of the interior and exterior with a damp cloth usually does the trick.
Yes, you can put foil in an air fryer — here’s how to do it safely. Putting foil in an air fryer is completely acceptable if you adhere to certain safety protocols. Follow these expert recommendations to use foil most effectively in your air fryer.
