The base of your air fryer basket plays a bigger role in cooking performance than most people assume. If your wondering what can i put at the bottom of my air fryer, you have several safe and useful options. Some add crispness, some catch grease, and some simply make cleanup faster. Picking the right one depends on what your cooking and how much mess you want to deal with later.
This guide covers every common option, from parchment paper to perforated mats. You will also learn what to avoid so you dont damage the nonstick coating or block airflow.
Why The Bottom Of The Basket Matters
Air fryers work by moving hot air around your food at high speed. The bottom of the basket is where that air enters and exits. If you cover it wrong, air cant circulate. Your food ends up soggy on one side and burnt on the other.
The bottom also takes the most abuse. Grease drips down, crumbs collect, and stuck food burns onto the surface. A simple liner or barrier can protect the coating and cut your cleaning time in half.
What Can I Put At The Bottom Of My Air Fryer
Here are the most popular and safe choices. Each one has trade offs, so read the notes before you buy anything.
1. Perforated Parchment Paper
This is the number one pick for most people. Perforated parchment has small holes punched through it. Air still flows, but grease and crumbs stay on the paper.
- Prevents food from sticking to the basket
- Makes cleanup as easy as tossing the paper
- Works well for fish, veggies, and breaded items
- Must be weighted down with food so it doesnt fly into the heating element
Never use regular parchment paper without holes. It blocks airflow and can burn if it touches the top heating coil. Also, dont preheat with loose parchment inside. The fan will lift it up.
2. Aluminum Foil
Foil is cheap and handy, but you need to use it right. You can line the bottom with foil, but only if you poke holes in it. Without holes, air cant move and your food steams instead of crisps.
- Tear a piece slightly larger than the basket bottom.
- Poke 10 to 15 small holes with a fork or skewer.
- Press the foil flat against the bottom.
- Add your food and cook as normal.
Foil is great for greasy foods like bacon or chicken wings. It catches the fat so it doesnt smoke. Just dont let the foil touch the heating element. That can cause a short or a fire.
3. Silicone Air Fryer Liners
Silicone liners are reusable and come in two styles. One is a flat mat with holes. The other is a deep bowl shape with ridges. Both sit at the bottom of the basket.
- Flat mats let air pass through and stop sticking
- Bowl liners catch grease and keep the basket spotless
- Dishwasher safe and lasts for years
- Can slow cooking slightly because they block some airflow
If you use a bowl liner, flip food halfway through. The sides of the bowl can block hot air from reaching the bottom layer of food.
4. A Small Rack Or Trivet
A metal rack lifts food off the bottom. This lets air flow under the food, which gives you crispier results. It also lets grease drip away instead of pooling.
Use a rack that fits your basket size. Stainless steel is best. Avoid racks with sharp legs that can scratch the nonstick coating.
5. Nothing At All
Sometimes the best answer is to leave the bottom empty. Most air fryer baskets are designed to work without any liner. If your food isnt sticky and your basket is clean, you dont need anything.
This is the safest option for high heat cooking. No liner means no risk of blocking airflow or melting plastic.
What You Should Never Put At The Bottom
Some items seem like good ideas but cause problems. Avoid these at all costs.
- Regular parchment paper with no holes
- Wax paper or paper towels
- Plastic wrap or plastic lids
- Glass plates or ceramic dishes not rated for air fryers
- Loose foil that can fly into the heating coil
- Wet batter directly on the basket bottom
Paper towels are a common mistake. They can catch fire near the heating element. Wax paper melts and leaves a mess. Plastic releases fumes that are not safe to breathe.
How To Choose The Right Option
Ask yourself three questions before you pick a liner.
- Is my food greasy or dry?
- Do I want to clean the basket or just toss a liner?
- Does my recipe need maximum airflow?
For greasy food, use foil with holes or a silicone bowl. For dry food like fries, use a perforated mat or a rack. For sticky food like fish, parchment with holes works best.
If your not sure, start with nothing. Then add a liner only if you have a sticking or cleaning problem.
Cleaning Tips For The Basket Bottom
Even with a liner, the bottom needs some care. Follow these steps to keep it in good shape.
- Let the basket cool before washing
- Soak it in warm soapy water for 10 minutes
- Use a soft sponge, never steel wool
- Dry fully before putting it back
- Check the coating for chips or scratches
If food is stuck on, make a paste with baking soda and water. Let it sit for five minutes. Wipe it away with a cloth. This removes burnt residue without scratching.
Common Mistakes People Make
One big mistake is covering the entire bottom with a solid liner. This turns your air fryer into a tiny oven. Food cooks unevenly and takes longer.
Another mistake is using a liner that is too small. It slides around and can flip up into the fan. Always match the liner to your basket size.
Some people stack two liners for extra protection. This blocks even more air. One liner is always enough.
Final Thoughts On Basket Liners
The bottom of your air fryer is not just a floor. It controls how air moves and how your food cooks. Parchment with holes, foil with holes, silicone mats, and small racks are all safe choices. Each one solves a different problem.
Pick the option that fits your recipe and your patience for cleaning. When in doubt, leave the bottom empty and let the machine do its job. A clean basket and good airflow will always beat a fancy liner.
