Air Fryer Liners Curling Up? Which Ones Stay Flat and Why
Light paper liners lift in the fan and curl onto the food. Fix the curl for free, then switch to a rigid silicone liner that holds its shape.

Quick answer
Paper liners curl because the air fryer fan blows under the light sheet and lifts the edges, and a liner with little food on it is the worst. Cut it to fit, load food before the fan starts and never preheat with a liner in place. For a liner that stays put every cook, use a rigid silicone liner with raised sides that fits your basket.
Free fix vs. permanent fix
Trim it, crease it, weigh it with food
- Cut parchment to fit the floor, not the walls
- Crease the sides before loading
- Put food on the liner before the fan starts
- Preheat the basket empty, with no liner
How long it lasts: One cook at a time. Light foods like a few fries or wings still lift the edges, so you repeat the steps every batch.
A rigid silicone liner with raised sides
Silicone is heavy and stiff enough that the fan cannot lift it, and the raised sides catch drips. You set it in once, and there is nothing to weigh down or trim.
What to get: Rigid silicone air fryer liner
How long it lasts: Reusable for a long time if you wash it after each use. It is stiff, so the fan cannot flip it.

Why it happens
Airflow under a light sheet
The fan pushes hot air down and around the basket. Thin paper has nothing to hold it, so air gets under it and lifts the edges. A liner with little food on it flaps the most.
A liner cut too big
Paper that runs up the walls has no weight on it and lifts straight into the airflow. It can also touch the heating element, which is a fire risk.
Preheating with the liner in
A preheat gives you a hot, empty basket and a loose sheet. Many liners curl, and some scorch.
Thin silicone that warps
Soft silicone with no ribbing or raised walls can warp with heat or sit crooked in the basket, then fold up at the corners.
Storage in a roll or a fold
A liner kept rolled or folded in a drawer remembers the bend and springs back up in the heat.

Do these in order, starting with the simplest.
-
Measure the basket floor
Tool used: Tape measureMeasure the flat floor, not the top. Cut the liner a little smaller than the floor so it lies flat and leaves the air holes clear.
-
Crease the sides
Tool used: Parchment sheetsFold the edge up about half an inch and press hard to make a sharp crease. The sheet then sits like a shallow tray and resists the airflow.
-
Preheat the basket empty
If your recipe calls for a preheat, run the basket alone for a few minutes with no liner. Add the liner when you add the food.
-
Load before the fan starts
Put the food on the liner and slide the basket in before you press start. Spread pieces to all four corners so every edge has weight on it.
-
Flatten stored liners
If a paper or silicone liner arrived rolled or has been folded, flatten it under a heavy book overnight before you use it.
-
Switch to a liner made to stay flat
Tool used: Rigid silicone air fryer linerIf you cook light foods often, a rigid silicone liner needs no weight and no trimming. Set it in the basket and it stays.

When free fixes aren't enough
The free steps work one batch at a time, but light foods will keep lifting paper whenever the fan is strong. If you air fry most days, trimming and creasing a fresh sheet every time gets old fast. A rigid silicone liner holds its shape and its sides catch grease. It blocks some airflow under the food, so a few foods crisp slightly less. If you see smoke, or paper touches the heating element, switch the unit off and unplug it.

Rigid silicone air fryer liner
Fixes: liners that lift, curl or flap in the airflow
Look for: Stiff walls that hold their shape, not a floppy mat; Holes or raised ridges so air can reach the food; A size that fits your basket and a heat rating that matches your manual; Food-grade silicone that the maker lists as dishwasher-safe.

How to size a liner for your basket
Measure the flat floor of the basket, front to back and side to side, or across for a round one. Pick a liner a little smaller than that floor, so the sides do not ride up the basket walls. Two-drawer air fryers need a liner for each drawer.
Parchment, silicone or foil
- Parchment: disposable and easy, but light and prone to lifting.
- Silicone: stays flat, washes and reuses, but blocks some airflow under the food.
- Foil: only if your manual allows it, and never loose where it can touch the heating element.
What to skip
Foil, oversized sheets and pinning paper down
Loose foil or oversized paper blocks airflow and can touch the heating element, so check your manual before using either. Skip tape, clips and toothpicks to pin paper in place. Skip stacking two liners too, which traps heat and grease.
