If you’ve ever wondered whether parchment paper or aluminum foil is better in an air fryer, you’re not alone. Many home cooks, especially beginners, want to keep their air fryer baskets clean and their food crispy without making a mess or causing safety issues. But using the wrong liner can affect airflow, cooking time, and even raise safety concerns.

In this guide, we’ll explore when to use parchment paper, when foil might be the smarter choice, and when to skip both altogether. You’ll learn the why behind each option so you can air-fry smarter, not harder.

Why This Method Works

Air fryers cook food by circulating hot air rapidly around the basket. Proper airflow is what creates that signature crisp finish without extra oil.

When you line your basket with parchment paper or foil, you introduce a barrier between the food and the air. The trick is to choose the right liner for the right job, and use it safely, so that you don’t sacrifice texture or taste.

• Parchment paper allows airflow while preventing sticking and soaking up grease.
• Aluminum foil reflects heat and contains drips, but it can block circulation if placed incorrectly or entirely cover the basket holes.

Understanding these basics will help you pick the best liner every time.

What You’ll Need

Depending on your choice, you’ll need one or more of the following:

• Air fryer-safe parchment paper (perforated or cut to fit the basket)
• Heavy-duty aluminum foil (food-grade, plain—not non-stick or flavored)
• Kitchen scissors or a paper punch to create air holes (if using regular parchment or foil)
• Tongs for safely placing and removing liners
• Food-safe spray oil (optional, for extra nonstick protection)

Optional substitutes:

• Silicone air fryer liners or reusable mats (eco-friendly and dishwasher-safe alternatives)

Step by Step: How to Use Parchment Paper Safely in the Air Fryer

• Preheat your air fryer (if your model requires it). Avoid inserting parchment into an empty, hot basket—it can blow around and catch on heating elements.
• Cut parchment to size. The paper should cover only the basket’s base, leaving about a 1-inch gap around the sides for air circulation.
• Add holes if needed. If you use regular parchment instead of pre-perforated sheets, punch several small holes to allow heat to circulate evenly.
• Place food on top immediately. Always secure parchment paper with food before turning on the air fryer. Loose paper can lift and burn.
• Adjust cooking times slightly. Because parchment absorbs oil and moisture, some foods (like fresh veggies) may cook a minute or two faster than usual.

Best for: Cookies, fish, cakes, sticky glazes, and foods prone to sticking.

Avoid when: Cooking foods that need heavy browning or crisping underneath, like bacon or fries.

Step by Step: How to Use Aluminum Foil in the Air Fryer

• Check your air fryer’s manual. Some manufacturers specifically warn against foil use—particularly in basket-style models. Always follow your brand’s guidance.
• Trim foil to fit the basket bottom. Avoid covering all the vents or holes. The air needs to flow freely.
• Create a shallow foil “tray” or “bowl.” Fold the edges up slightly to catch grease or sauce, keeping everything tidy.
• Load the food. Place heavier items like meat or root vegetables on the foil—these stay put and cook evenly.
• Monitor closely. Foil reflects heat, so cooking may be faster. Check texture halfway through to prevent over-browning.

Best for: Juicy meats, roasted vegetables, and high-fat foods that drip oil.

Avoid when: Cooking acidic ingredients (like tomatoes or citrus marinades)—the acid can react with aluminum and alter the taste or color.

Pro Tips & Best Practices

• Perforate your liner. Whether foil or parchment, adding small holes helps preserve circulation and prevents soggy results.
• Do not preheat with empty liners. Always secure the liner with food; lightweight paper or foil can fly up into the heating coil.
• Keep airflow your top priority. Air fryers work by convection, so don’t block vent holes or stack food too heavily.
• Invest in reusable silicone liners. They’re heat-resistant, easy to clean, and designed specifically to maintain airflow.
• Avoid single-use overload. Too much foil or parchment can trap heat and cause uneven cooking, or even set off your air fryer’s safety sensor.

Questions About Parchment Paper and Foil in Air Fryers

1. Can you put parchment paper in an air fryer safely?

Yes, as long as it’s air fryer-safe (heat-resistant to at least 425°F / 220°C) and held down by food. Don’t use it alone during preheating since it might lift and contact heating elements.

2. Is aluminum foil safe to use in all air fryers?

Not always. Basket-style fryers may direct air straight upward, causing foil to block circulation or fly up. Check your user manual, some brands, like Philips or Ninja, allow partial use; others discourage it entirely.

3. What foods should you not cook on parchment paper?

Avoid breaded or heavily breaded foods that need direct heat on the bottom to crisp—like mozzarella sticks or frozen fries. They may come out soft on one side.

4. Why do some recipes say never to use foil in air fryers?

Because foil can block airflow, causing uneven results. Also, if acidic sauces (like lemon or tomato-based marinades) contact foil, a chemical reaction can occur, creating a metallic taste.

5. What’s the difference between parchment and wax paper in an air fryer?

Never use wax paper, it’s coated with wax that can melt or ignite at high temperatures. Parchment paper is heat-safe and designed for baking and air frying.

6. Can you reuse parchment paper or foil in the air fryer?

You can reuse foil for one or two short sessions if it’s clean and intact. Parchment paper, however, tends to weaken and darken with heat—best to use fresh sheets each time.

When NOT to Use Liners in the Air Fryer

Avoid using parchment paper or foil when:

• Preheating an empty air fryer Paper can fly up and scorch against the coil.
• Cooking foods that rely on direct heat Like searing steak, reheating pizza crust, or crisping hash browns.
• Cooking with marinades containing lemon, vinegar, or tomato (foil only) Acidic ingredients can pit aluminum and affect flavor.
• Trying to maximize crispiness Bare basket equals better airflow.

Sometimes the best liner is no liner at all, especially when you want that extra crunch.

Alternative Methods or Solutions

If you want the benefits of easy cleanup without worrying about paper or foil, try these:

• Reusable silicone liners — Dishwasher-safe, nonstick, and designed for airflow.
• Perforated air fryer mats — Made for specific models; ideal for fries and small items.
• Oil spritz + minimal cleanup — A light spritz of oil often prevents sticking just as well.

Each solution offers something unique, choose based on your recipe, convenience, and sustainability goals.

The Better Choice Depends on What You’re Cooking

So, is parchment paper or aluminum foil better in an air fryer?

It depends:

• Use parchment paper when you want a nonstick surface for delicate foods or easy baking cleanup.
• Use aluminum foil when working with heavy, greasy, or saucy foods that may drip or burn onto the basket.
• Skip liners altogether for crispy textures or when your recipe depends on direct airflow.

By understanding how each liner interacts with heat and airflow, you can make smarter, safer decisions that protect your appliance and improve results.

Bottom line: Parchment is the everyday go-to for most air-fried dishes; foil has its place, but only when used wisely.

Cook confidently, keep your air fryer happy, and enjoy cleaner, crispier meals, no mess and no guesswork.
