Most air fryer liners are safe, but the material and temperature matter

Air fryer liners — also called parchment paper liners or silicone baskets — are generally safe to use in air fryers, but not all liners work the same way. The main risk is heat damage: if a liner is made from material with a low smoke point, it can break down, discolor, or release fumes when exposed to the high temperatures inside an air fryer. Most liners sold specifically for air fryers are rated to handle 400°F to 500°F, which covers the temperature range of most home air fryers.

The safest liners are made from either perforated parchment paper or food-grade silicone. Perforated parchment paper has small holes that let hot air circulate around your food, which is why it works better in an air fryer than solid parchment. Silicone liners are reusable and durable, but they can retain odors and stains over time. Both types are widely available and inexpensive.

Key Takeaways

  • Perforated parchment paper liners and food-grade silicone liners are the safest options for air fryers because they are rated for high heat.
  • Regular parchment paper (not perforated) can block airflow and cause uneven cooking, so use only liners designed for air fryers.
  • Check the temperature rating on the package — it should be at least 400°F, and ideally 420°F or higher.
  • Avoid liners made from plastic or aluminum foil, as plastic will melt and foil can damage your air fryer's heating element.

Parchment paper liners vs. silicone liners

Perforated parchment paper liners are the most common choice. They sit flat in the basket, catch grease and crumbs, and make cleanup much faster. Because they are perforated (full of small holes), air still circulates underneath your food, so you get the same crispy results as cooking directly on the basket. Most parchment liners are rated to 420°F or 430°F, which is safe for nearly all home air fryer models.

Silicone liners are reusable baskets or mats made from food-grade silicone. They last for years if you wash them by hand and store them flat. The downside is that they are thicker than parchment, so they take up more space in the basket and can reduce the amount of food you fit. Silicone also absorbs flavors and oils, so a liner used for fish may retain that smell even after washing. Most silicone liners are rated to 450°F or 500°F, making them safe for high-heat cooking.

For occasional use, parchment liners are cheaper and more convenient. For frequent cooking, silicone liners save money over time because you do not have to buy new parchment every few months.

Why regular parchment paper is not the same as air fryer liners

Regular parchment paper — the kind you use for baking — is not perforated and can block airflow in an air fryer. When you line the basket with solid parchment, hot air cannot reach the bottom of your food, so it steams instead of crisps. You may also notice that the paper curls up or moves around during cooking, which can block the heating element or cause uneven cooking.

Perforated parchment is designed specifically to solve this problem. The holes are small enough to catch grease and crumbs but large enough to let air flow through. If you only have regular parchment at home, you can poke holes in it yourself with a fork or knife, but it is easier and safer to buy liners that are already perforated.

Materials to avoid in your air fryer

Plastic liners or plastic-coated papers should never go in an air fryer. Plastic melts at temperatures well below 350°F, so it will warp, release chemicals, and potentially damage your air fryer. Check the package label to make sure the liner is made from parchment or silicone, not plastic or plastic-coated material.

Aluminum foil is also not recommended. While foil does not melt, it can reflect heat unevenly and damage the heating element or interior coating of your air fryer over time. Some air fryer manufacturers specifically warn against foil in their manuals. If you want to use foil, check your air fryer's manual first.

Paper towels are not safe either. They are not rated for high heat and can catch fire or release fibers into your food. Stick to liners made from materials designed for air fryers.

How to check the temperature rating on a liner

Before you buy an air fryer liner, look at the package for a temperature rating. It should say something like "safe to 420°F" or "heat resistant to 450°F." Most home air fryers operate between 300°F and 400°F, so a liner rated to 420°F or higher is safe for normal use. If the package does not list a temperature rating, do not buy it — you cannot know whether it is safe.

Some liners are sold as "oven-safe" but not rated for air fryer use. Oven-safe does not always mean air fryer-safe, because air fryers heat much faster and more intensely than ovens. Look for liners labeled specifically for air fryers or convection ovens, or check the temperature rating to make sure it is at least 400°F.

Tips for using liners safely

Place the liner in the basket before you add food. If you put the liner in after the air fryer is preheated, it may move around or fold up when you close the basket. Make sure the liner sits flat and does not cover the heating element or vents.

Do not overlap liners or stack them. Using more than one liner at a time reduces airflow and can cause hot spots or uneven cooking. If you need more coverage, use a larger liner or cook in batches.

Let the air fryer cool before you remove the liner. Parchment liners can be reused several times if they are not torn or heavily stained, so you can save money by washing and drying them. Silicone liners should be washed by hand in warm soapy water and dried completely before storage.

What happens if a liner gets damaged

If a parchment liner tears or burns during cooking, remove it and finish cooking without it. A small tear is not dangerous — the liner will not fall apart or contaminate your food. However, if the liner is heavily burned or falling apart, throw it away and use a new one next time.

If a silicone liner cracks or peels, it is no longer safe to use. Cracks can trap bacteria and food particles, and peeling silicone can shed into your food. Replace it with a new liner.

Frequently Asked Questions

Can I use parchment paper liners in a convection oven?

Yes, most parchment liners rated for air fryers are also safe for convection ovens. Check the package label to confirm the temperature rating matches your oven's maximum temperature. Convection ovens typically run cooler than air fryers, so a liner rated to 420°F will work in most home convection ovens.

Do air fryer liners affect cooking time or crispiness?

Perforated parchment liners have almost no effect on cooking time or crispiness because air still circulates underneath your food. Silicone liners may slightly increase cooking time because they are thicker and absorb some heat. If you notice food is not as crispy with a silicone liner, try increasing the temperature by 10°F or cooking for an extra minute or two.

Are silicone liners better than parchment liners?

Neither is objectively better — it depends on how often you cook. Parchment liners are cheaper per use and create less mess, but you have to buy new ones regularly. Silicone liners cost more upfront but last for years and reduce waste. Both are safe and effective.

What should I do if a liner catches fire?

Turn off the air fryer when ready and unplug it. Let it cool completely before opening the basket. A liner should not catch fire if it is rated for the temperature you are using, so if this happens, the liner was not rated for your air fryer's heat. Do not use that brand again.

Can I wash and reuse parchment liners?

Yes, parchment liners can be washed and reused several times if they are not torn or heavily stained. Rinse them under warm water, dry them completely, and store them flat. After a few uses they may become brittle or discolored, at which point it is time to replace them.
