What to Put Under Food in an Air Fryer

You opened the air fryer basket, looked at the holes, and wondered what belongs under the food.

That question matters because an air fryer cooks with fast-moving hot air. Block that airflow, and fries turn soft, chicken skin stays pale, and cleanup still becomes annoying.

This takes about 8 minutes to read. By the end, you’ll know which liner to use, when to skip one, and which materials create safety problems.

Best Thing to Put Under Food in an Air Fryer

The best thing to put under food in an air fryer is often nothing. The basket holes exist so hot air can move under the food.

When food sits directly on the crisper plate, moisture escapes faster. That gives potatoes, wings, nuggets, vegetables, and breaded foods a better crust.

Use a liner only when the food sticks, drips, melts, or breaks apart. The liner solves one problem but can create another problem by reducing airflow.

The key decision is simple: crispiness first, cleanup second. If the food already holds its shape, start with no liner.

Use Parchment Paper for Sticky Air Fryer Foods

Parchment paper is the best under-food choice for delicate or sticky air fryer foods. It helps fish, dumplings, marinated chicken, tofu, and baked goods release cleanly.

The safest option is perforated parchment paper made for air fryer baskets. The holes allow grease, steam, and hot air to move better than a solid sheet.

Food must always weigh parchment down. Philips warns that loose baking paper can lift into the heating element and burn when air moves through the fryer.

How to Place Parchment Paper Under Food

Cut parchment slightly smaller than the basket floor. Paper that climbs the basket wall can block air and brown food unevenly.

1. Preheat the air fryer empty, if your recipe needs preheating.
2. Place parchment flat on the crisper plate.
3. Add food right away to hold the paper down.
4. Keep food in one layer for better airflow.
5. Stop cooking if the paper smells scorched.

Choose parchment when sticking matters more than maximum crunch. Choose no liner when crispiness matters most.

Use Aluminum Foil Only in the Right Air Fryer Situation

Aluminum foil can go under food in some air fryers, but it needs stricter placement rules. Foil blocks airflow faster than parchment because it has no built-in holes.

Use foil for heavy foods that hold it down, such as ribs, meatballs, bacon, or saucy chicken. Avoid foil under lightweight food that can shift during cooking.

Never use foil with acidic foods. Tomato, lemon, vinegar, and citrus marinades can react with aluminum and affect flavor.

Foil Rules That Prevent Bad Results

Foil works best when it catches drips without sealing the air path. The air fryer still needs open space around the food.

• Keep foil below the food, not above it.
• Leave basket holes open around the edges.
• Keep foil away from the heating element.
• Weigh foil down with food every time.
• Avoid foil with tomato, lemon, or vinegar.

You might think foil makes every air fryer meal easier. The tradeoff is texture, because trapped steam softens the bottom of crisp foods.

Use Silicone Liners for Reusable Air Fryer Cleanup

Silicone liners are the best reusable option under food in an air fryer. They reduce sticking, catch drips, and save you from using disposable paper each time.

The tradeoff is airflow. Many silicone bowls have raised ridges, but they still create more steam than an open basket.

Use silicone liners for saucy food, reheated leftovers, sticky vegetables, and small items that fall through grates. Skip silicone for fries, wings, and anything you want deeply crisp.

The best silicone liner has raised ridges or small drain channels. Flat silicone mats trap moisture under food faster.

What Not to Put Under Food in an Air Fryer

Some materials should never go under food in an air fryer. Fast airflow and high heat make unsafe materials riskier than they look.

Never use wax paper. Wax paper looks like parchment, but the coating can melt and smoke under air fryer heat.

Never use plastic wrap, plastic containers, paper towels, cardboard, or regular paper. These materials can melt, scorch, blow into the heating element, or contaminate food.

What Most People Get Wrong About Air Fryer Liners

Most people think the liner’s job is to protect the basket. The liner’s first job is to support the food without ruining airflow.

• Wrong belief 1: Covering every hole makes cleanup better.
• Correction: Covered holes reduce air movement and soften food.
• Wrong belief 2: Parchment paper is safe during preheating.
• Correction: Loose parchment can lift and burn.
• Wrong belief 3: Foil works for every food.
• Correction: Acidic foods and foil do not pair well.

What most people don’t think to ask is whether the food needs bottom airflow. That question matters more than the liner brand.

How to Choose the Right Air Fryer Liner Fast

Choose the liner based on the food’s job. Crisp food needs open air, sticky food needs release, and greasy food needs drip control.

If you are cooking fries, wings, nuggets, Brussels sprouts, or breaded frozen snacks, use no liner. Shake halfway so all sides meet hot air.

If you are cooking fish, tofu, dumplings, cookies, or soft pastries, use perforated parchment. It gives support without trapping as much steam.

If you are cooking bacon, saucy chicken, meatballs, or marinated food, use a small foil tray or silicone liner. Keep the edges open for air movement.

How to Keep the Basket Clean Without Blocking Airflow

You can keep an air fryer basket clean without covering the whole bottom. The trick is using small protection only where the mess starts.

Brush a tiny amount of oil on the food, not the basket. Direct aerosol spray can damage some nonstick coatings over time.

Soak the basket soon after cooking, while residue is still soft. Warm water and dish soap remove most grease before it hardens.

1. Let the basket cool until safe to touch.
2. Remove loose crumbs with a soft brush.
3. Soak the basket for 10 minutes.
4. Clean with a non-abrasive sponge.
5. Dry fully before storing.

This method keeps the basket open for airflow and still protects the surface. For sticky meals, add parchment only under the sticky part.

Frequently Asked Questions

Can I put parchment paper under food in an air fryer?

Yes, you can put parchment paper under food in an air fryer when food weighs it down. Use perforated parchment for better airflow. Never place parchment inside during preheating because the fan can lift it into the heating element.

Can I put foil under food in an air fryer?

Yes, you can put foil under food in an air fryer if the foil stays weighted and does not block the whole basket. Keep foil away from the heating element. Avoid foil with acidic foods like tomato, lemon, vinegar, or citrus marinades.

Is silicone safe under food in an air fryer?

Food-grade silicone liners are safe under air fryer food when rated for the cooking temperature. Choose a ridged or perforated silicone liner for better air movement. Flat silicone works for cleanup but can make crisp foods softer.

Should I put water under food in an air fryer?

You can add a small amount of water to the drawer under greasy foods if your air fryer manual allows it. Water helps reduce smoke from dripping fat. Do not add water to the main basket or use enough to steam the food.

Why does food get soggy when I use an air fryer liner?

Food gets soggy when the liner blocks airflow or traps steam under the food. Solid parchment, foil, and deep silicone bowls can slow browning. Use no liner for crispy foods, or choose perforated parchment when sticking is the main problem.
