If you’ve ever opened your air fryer mid-cook to find parchment paper curled, burned, or stuck to your food, you’re not alone in the culinary world. Parchment paper is supposed to make cleanup easy, but when it starts flying around or folding up, it can block airflow, ruin cooking results, or even jam your heating element.

Fortunately, once you understand why parchment paper curls and how to keep it flat, you can fix the problem for good. In this guide, you’ll learn the best techniques, product tips, and safety precautions to make parchment paper behave perfectly every time you air fry.

Quick Recap: Why and How to Stop Parchment Paper Curling

• Curling happens due to heat, airflow, and lack of weight.
• Cut parchment to exact size and perforate for airflow.
• Dampen edges, avoid preheating with it inside, and weigh it down with food.
• Use the right type— high-heat parchment or commercial air fryer liners.
• Always prioritize safety and never leave parchment unanchored in a hot basket.

Why Parchment Paper Curls in the Air Fryer

1. The science of drying and expansion Parchment paper is made from cellulose fibers that expand when exposed to heat and dry air. In an air fryer, the constant circulation of hot air rapidly draws moisture out of one side, usually the top, causing uneven contraction. That’s what makes the paper twist or lift around the edges.

2. Airflow turbulence Your air fryer is essentially a small convection oven with a strong fan. The hot air rushing around creates lift—like wind under a kite. Light, unanchored parchment easily catches that airflow, rising and curling upward.

3. When it becomes serious This might seem minor, but curled parchment can:

• Block airflow and cause uneven cooking
• Fly up and contact the heating coil, creating a fire hazard
• Wrap around food, preventing crisping
• Stick to melted cheese or sauce, making cleanup harder

4. Common misconceptions

• “All parchment paper is air fryer safe.” Not true—some brands or coated types can’t withstand high air fryer temperatures (some go no higher than 420°F).
• “Curling doesn’t affect cooking.” It does—blocked airflow means soggy fries or limp chicken, not the golden crisp you want.
• “You can preheat with parchment already inside.” A big no: it may overheat and rise before any food weighs it down.

Tools and Materials You’ll Need

Item	Why You Need It	Notes
Parchment paper (unbleached preferred)	Nonstick surface that resists grease	Choose high heat–rated (≥450°F)
Air fryer–safe parchment liners with holes	Allow air circulation, reduce lift	Use the right size for your basket
Heatproof weights or food itself	Keeps paper flat	Never use metal weights in convection flow

7 Steps to Stop Parchment Paper from Curling in the Air Fryer

Step 1: Cut the Parchment to Fit Exactly

• Trim parchment so it covers only the basket’s bottom.
• Leave a small margin around edges so air can circulate freely.
• Too large a sheet lifts and melts against the side walls.

Step 2: Create Air Holes if Needed

• If you’re using a plain sheet, punch several small holes (a fork or hole punch works).
• Holes let heat escape and prevent upward air pressure that causes curling.
• Commercial liners already have this perforation design.

Step 3: Slightly Moisten the Paper

• Lightly dampen one side of the parchment under running water.
• Shake off excess moisture—it should be barely dewy, not wet.
• The added surface tension helps it cling to the basket bottom until food holds it down.

Step 4: Preheat the Air Fryer Without Parchment

• Always preheat the basket empty, not with parchment inside.
• Once preheat is done, place the parchment and immediately add your food.
• Direct contact with heat flow before food is added causes the paper to lift.

Step 5: Anchor with Food Weight Right Away

• Spread your ingredients evenly over the parchment.
• Avoid piling food too high in one corner—balance is key.
• The gentle pressure from food keeps edges flat and stable during cooking.

Step 6: Adjust Air Speed (If Your Model Allows It)

• Some air fryers have variable fan or temperature settings.
• Slightly reducing fan speed early on helps prevent paper lift during the first minute.
• Once food begins to release moisture, the paper stays in place naturally.

Step 7: Check After the First Minute

• Pause the cook cycle and confirm the parchment hasn’t shifted.
• If it’s curling, add small pieces of food on any raised corners to anchor them.
• Never reach into a hot fryer with bare hands—use tongs or silicone tools.

Scientific Reasoning Behind These Steps

Hot air expands and moves faster than cooler air, creating upward lift. Lightweight materials like parchment act like sails, catching that fast-moving air. Moistening or weighting the paper helps counter this lift, while holes allow pressures to equalize across the surface. In short, you’re controlling two scientific principles: airflow balance and heat distribution.

Common Mistakes to Avoid

• Preheating with parchment inside – the biggest cause of smoking and curling.
• Using oversized sheets – increases drag area, causing lift.
• Insufficient food weight – the fan will blow it up instantly.
• Incorrect paper type – wax paper or non–high-heat parchment can burn or smoke.
• Covering entire walls with parchment – restricts air movement and cooks unevenly.

DIY Fixes vs. Commercial Parchment Liners

Option	Pros	Cons
DIY Cut Sheets	Custom fit, inexpensive, always available	Requires effort and proper punching of holes
Commercial Perforated Liners	Even airflow design, convenient packs, perfect circles	Slightly more costly, may not fit all baskets perfectly
Reusable Silicone Liners	Durable, no waste, easy cleanup	Slightly longer cook times, less crisp texture compared to parchment

If you air fry often, reusable silicone liners might save money and frustration, though parchment still gives the best crisping.

What NOT to Do

• Never use wax paper—wax coating melts and releases fumes.
• Don’t line your entire air fryer tray wall-to-wall—it needs air space to cook properly.
• Don’t tuck parchment under the basket—it blocks the heating element’s airflow.
• Avoid excessive oil on or under parchment—it can soak in and singe at high temps.

Handy Expert Tips and Hacks

• Pre-punch and store: Stack a batch of pre-cut, perforated sheets so they’re ready to grab.
• Edge fold hack: Gently curl parchment in the opposite direction before use to counter its packaging roll.
• Use a trivet: If your fryer includes a metal rack or trivet, place it over the paper once food is arranged—it keeps everything anchored securely.
• Choose branded “air fryer liners”: These are thinner and balanced for airflow, unlike oven parchment meant for larger, slower heat environments.
• Keep it dry: Although light misting helps, never air fry with a soaked sheet—it can generate steam and extend cook times.

When to Call It Quits and Go Without

Skip parchment altogether when:

• You’re cooking very greasy or marinated foods that baste themselves—like wings or bacon.
• You need max crispness (e.g., fries)—direct contact with the basket gives better texture.
• Your fryer has a nonstick coating and cleans easily.

Sometimes, the simplest solution is no parchment at all—especially for short or dry cooks under 10 minutes.

Cost, Time, and Effort Considerations

Criterion	DIY Parchment	Pre-cut Liners	Silicone Liner
Cost per use	Lowest ($0.02–0.05)	Moderate ($0.10–0.20)	Higher upfront ($10–$15 one-time)

Choose the one that fits your cooking style—DIY for tinkerers, liners for convenience, silicone for sustainability.

Related Safety Reminders

• Always place food on top of parchment before starting the air fryer.
• Never let parchment touch the fan or heating coil.
• Empty baskets with loose liners can fly up quickly—always secure before cooking.
• Watch first-time trials closely to understand how your specific model behaves.

Frequently Asked Questions

1. Can I use parchment paper at 400°F in the air fryer?

Yes, use parchment labeled for at least 425°F. Regular baking parchment is generally safe up to 450°F. Always follow brand guidelines.

2. Why does my parchment paper burn or darken?

This happens when the sheet touches the heating element or overhangs beyond the basket. Trim it smaller and skip the preheat while it’s inside.

3. What’s better— foil or parchment paper in an air fryer?

Parchment is safer because it doesn’t block airflow as much as foil. Foil can trap heat pockets and isn’t recommended for very greasy foods.

4. Can I reuse parchment paper in my air fryer?

Only once or twice if it’s not stained or brittle. Reusing heavily exposed parchment can cause breakup and curling from structural weakness.

5. Are silicone mats better than parchment paper for air fryers?

Silicone mats are reusable and stable—no curling—but they may slightly slow airflow and crisping. Many home cooks keep both handy for different recipes.

6. Can I air fry with parchment for wet batters or coatings?

Yes, but ensure the batter is thick enough not to flow underneath. Too much moisture can soften the paper and affect cooking.

Preventive Maintenance for Safer Cooking

• Always wipe your air fryer basket completely dry before inserting parchment. Any grease film or residues create uneven suction and curling.
• Store parchment flat, not rolled, to avoid memory curl from the packaging.
• Check your fryer’s maximum paper size in the manual. Oversized sheets are one of the top fire hazard triggers in air fryers.

Conclusion

Curling parchment paper might seem like a small kitchen nuisance, but it can affect cooking quality and safety inside your air fryer. By understanding how heat and airflow interact with lightweight paper, you can eliminate the problem entirely.

To stop parchment paper from curling in the air fryer, cut it to fit, add perforations, lightly dampen or weigh it down, and never preheat with it inside. With these simple techniques, your parchment will stay flat, your air fryer will cook evenly, and your food will come out just the way it should, crispy, consistent, and perfectly safe.

Now it’s your turn: choose the right liner, test a few of these methods, and soon you’ll never have to battle curling parchment again.
