Can Cardboard Go in an Air Fryer? Find Out Now

Let’s be honest: air fryers have taken over our kitchens. From crispy fries to roasted veggies and even baked cookies, these little powerhouses do it all—fast, hot, and with minimal oil. But here’s a question that pops up more often than you’d think: can cardboard go in an air fryer? Maybe you’ve got a takeout box from last night’s Thai dinner, or a cardboard sleeve from your morning coffee, and you’re wondering if it’s safe to toss it in with your chicken wings. Or perhaps you’ve seen a TikTok trend of people using cardboard as a makeshift liner. You’re not alone—and you’re right to pause and ask before hitting that “start” button.

As someone who’s burned more than one kitchen mishap into memory (yes, I once tried to toast a paper towel in the toaster), I get the urge to cut corners and save cleanup time. But when it comes to heat, airflow, and flammable materials, it’s better to be safe than sorry. In this guide, we’re diving deep into the science, safety, and smart alternatives when it comes to using cardboard in your air fryer. Whether you’re a new air fryer owner or a seasoned pro, this post will answer your burning questions—without literally burning your kitchen down.

The Science Behind Air Fryers and Heat

How Air Fryers Work (And Why It Matters)

Before we talk about cardboard, let’s break down how air fryers actually work. Unlike traditional ovens that rely on radiant heat, air fryers use rapid air circulation. A heating element at the top heats the air, while a powerful fan pushes it down and around the food in a perforated basket. This creates a convection effect that crisps food from all sides—like a mini convection oven on steroids.

The temperature inside an air fryer can range from 175°F to 400°F (80°C to 200°C), depending on the model and setting. Most cooking happens between 350°F and 375°F. At these temperatures, airflow is constant and intense. That means anything placed inside isn’t just exposed to heat—it’s being blown around by hot air.

Why Materials Matter in High-Heat, High-Airflow Environments

Think of your air fryer like a mini wind tunnel. The combination of high heat and forced air creates a unique environment where materials behave differently than they would in a regular oven or on the countertop. For example:

• Paper towels can catch fire or blow into the heating element.
• Plastic containers can melt or release toxic fumes.
• Aluminum foil can spark or block airflow if used incorrectly.

Now, where does cardboard fit into this? Cardboard is made of compressed paper fibers, often treated with coatings, dyes, or even food-safe liners (in the case of takeout boxes). But even if it looks sturdy, cardboard has a low ignition temperature—typically around 427°F (220°C), but it can begin to smolder, char, or release fumes at lower temperatures, especially when airflow is constant.

And here’s a key point: air fryers often reach 400°F, which is dangerously close to cardboard’s ignition point. Even if it doesn’t burst into flames, smoldering cardboard can release carbon monoxide and other volatile organic compounds (VOCs)—not exactly what you want in your crispy chicken or roasted potatoes.

Is Cardboard Safe in an Air Fryer? The Short Answer

No, Cardboard Should Never Go in an Air Fryer

Let’s cut to the chase: you should never put cardboard in your air fryer. It’s not safe, not recommended by manufacturers, and not worth the risk. Even if it seems like a small piece or a “just this once” idea, the potential dangers far outweigh any convenience.

I once tried to use a cardboard sleeve as a liner to catch drippings from bacon. Big mistake. Within two minutes, the edges started to brown and curl. By minute four, a small wisp of smoke curled up from the basket. I yanked it out, heart racing, and learned my lesson the hard way. That tiny bit of cardboard could’ve started a fire or damaged my appliance.

What Happens When Cardboard Is Exposed to Air Fryer Conditions?

Here’s what goes down when cardboard meets hot air:

• Dehydration and warping: Cardboard dries out quickly, causing it to shrink, curl, or crack.
• Smoldering and charring: At 350°F+, cardboard begins to break down. It won’t always burst into flames, but it can smolder, releasing unpleasant smoke and odors.
• Airflow disruption: A warped or torn piece of cardboard can block the fan or fall into the heating element, causing a fire hazard.
• Chemical off-gassing: Many cardboard products are treated with glues, dyes, or plastic coatings (especially in food packaging). When heated, these can release harmful fumes.

And don’t be fooled by “food-safe” or “microwave-safe” labels. Microwave-safe cardboard is designed for short bursts of low-energy radiation, not sustained high heat with intense airflow. The two environments are completely different—and air fryer conditions are far more aggressive.

Real-Life Examples: When People Tried It

I’ve scoured forums, Reddit threads, and YouTube comments to find real cases where people attempted to use cardboard in air fryers. Here’s what happened:

• Takeout box liner: Someone used a cardboard box from Chinese takeout to catch grease from fried dumplings. The box caught fire after 6 minutes at 375°F. They had to unplug the air fryer and use a fire extinguisher.
• Cardboard sleeve for coffee: A user placed a coffee sleeve under a burger to prevent sticking. It caught on fire in under 3 minutes at 400°F.
• DIY drip tray: A “life hack” suggested cutting cardboard to size as a drip tray. Multiple users reported smoke, bad smells, and damage to their air fryer’s interior coating.

These aren’t rare flukes—they’re common outcomes when flammable materials meet high heat and airflow.

Why Do People Think Cardboard Is Okay?

Misconceptions and “Life Hacks” Online

So why do so many people consider using cardboard in their air fryers? A big reason is the rise of DIY kitchen hacks on social media. TikTok, Instagram Reels, and YouTube Shorts are full of videos showing “clever” uses for everyday items—like using a paper plate in the microwave or a coffee filter as a liner.

Some of these hacks work in specific appliances (like a paper towel in a microwave to absorb moisture), but they don’t transfer safely to air fryers. The intense airflow and higher temperatures make air fryers a different beast. Yet, the visuals are convincing: a clean basket, no mess, easy cleanup. It looks smart—until it isn’t.

The “It Worked Once” Fallacy

Another reason people keep trying it: they’ve gotten away with it before. Maybe they used a small piece of cardboard for one batch of fries, and nothing happened. That creates a false sense of security. But just because something didn’t catch fire this time doesn’t mean it’s safe. It’s like playing Russian roulette with your kitchen.

Think of it this way: you might leave your stove on for a few minutes with nothing on it and be fine. But that doesn’t mean it’s safe to do every day. The same logic applies to cardboard in air fryers. One success doesn’t prove safety—it just proves luck.

Confusion with Other Materials

Some people confuse cardboard with materials that are safe, like:

• Perforated parchment paper: Designed for high heat and airflow. Safe when used correctly.
• Aluminum foil: Can be used in air fryers if it’s secured and doesn’t block airflow.
• Silicone liners: Reusable, heat-resistant, and safe for air frying.

Cardboard looks similar to parchment paper—especially when it’s thin or white—but it’s fundamentally different. Parchment paper is treated with silicone and can withstand temperatures up to 450°F. Cardboard? Not even close.

Safe and Smart Alternatives to Cardboard

Use Parchment Paper (With a Caveat)

The best substitute for cardboard is parchment paper—but not just any kind. Look for air fryer-specific parchment paper or perforated parchment liners. These are pre-cut, have holes for airflow, and are designed to withstand high heat.

Here’s how to use it safely:

• Choose liners with pre-punched holes to allow hot air to circulate.
• Make sure the liner fits snugly in the basket—don’t let it hang over the edges.
• Never use parchment paper during preheating. Wait until the air fryer is at temp before adding food and liner.
• Use only one liner at a time—no stacking.

I use parchment liners for everything from salmon to roasted Brussels sprouts. They catch drips, prevent sticking, and make cleanup a breeze. Just toss the liner—no scrubbing required.

Try Silicone Air Fryer Liners

If you want something reusable, silicone liners are a fantastic option. They’re heat-resistant (up to 450°F), dishwasher-safe, and come in various shapes to fit different air fryer baskets.

Pros:

• Eco-friendly and long-lasting
• Easy to clean—just rinse or toss in the dishwasher
• No risk of burning or fumes

Cons:

• Can be pricier than parchment
• Some users report slight odor on first use (rinse with vinegar to remove)

I’ve had my silicone liners for over a year, and they still look brand new. They’re especially great for sticky foods like marinated chicken or caramelized onions.

Use Aluminum Foil (Correctly)

Aluminum foil can be used in air fryers, but with caution. Here’s how:

• Use heavy-duty foil to prevent tearing.
• Crinkle it slightly so it doesn’t block airflow.
• Don’t cover the entire basket—only line the bottom or sides.
• Never let foil touch the heating element.
• Avoid using foil with acidic foods (like tomatoes or citrus) unless it’s food-grade non-reactive foil.

Foil is great for catching grease or preventing food from falling through the basket. But it’s not a long-term solution like silicone or parchment.

Skip the Liner Altogether (Yes, Really)

Sometimes, the best alternative is no liner at all. Most air fryer baskets are non-stick and easy to clean. After cooking, just wipe with a damp cloth or use a soft brush. For sticky messes, soak the basket in warm, soapy water for 10 minutes.

I’ve found that with regular use, my basket stays clean with minimal effort. And by skipping liners, I avoid any risk of fire, smoke, or off-gassing. Plus, it’s zero waste—no paper or plastic to throw away.
