If you have used an air fryer for more than a few months, you have likely stared at the nonstick coating on the factory basket and wondered how long it will last. Scratches appear. Bits of breaded chicken stick. The coating starts to flake. That is the precise moment you start searching for alternatives. I have tested hundreds of kitchen products over the years, and the ones that last are never the flashiest — they are the simplest, heaviest, and most boring-looking tools in the drawer. Stainless steel air fryer trays fit that description perfectly.
When you swap the standard nonstick basket for a stainless steel tray, you change how heat moves through your food. Stainless steel does not have the slick surface of a chemical coating. It does not warp at high temperatures. It does not release toxic fumes if you accidentally overheat it. For anyone who cares about thermal retention — and as a mixologist, I care deeply about how heat (or cold) transfers from a surface to what you are cooking — stainless steel offers predictable, even heat distribution. This guide explains why these trays work, how to use them without frustration, and what you need to know about cleaning and seasoning them.

Key Takeaways
- Stainless steel air fryer trays distribute heat more evenly than nonstick baskets, reducing hot spots.
- They require a thin layer of oil or a pre-seasoning step to prevent sticking — this is not a flaw, it is physics.
- Cleaning is straightforward with hot water and a stiff brush; avoid abrasive scrubbers that damage the surface.
- These trays last indefinitely if you do not overheat them dry and you store them properly.
Why Stainless Steel Trays Change How Your Air Fryer Works
Most air fryers ship with a nonstick-coated basket. The coating is usually PTFE (polytetrafluoroethylene), which is slick when new but degrades over time. Once the coating is scratched, food sticks worse than it would on bare metal. Stainless steel does not have that problem because it does not rely on a coating. The material itself is non-reactive and durable up to about 500°F (260°C).
From a thermodynamics standpoint, stainless steel has a lower thermal conductivity than aluminum but higher specific heat capacity. That means it takes longer to heat up, but once hot, it holds that temperature more steadily. For air frying, this translates to fewer temperature swings when you open the drawer and add cold food. The tray acts as a thermal reservoir, smoothing out the heating cycle.
I have used stainless steel inserts in my countertop oven for crisping chicken wings and reheating pizza. The crust comes out uniformly brown because the tray does not have cold spots where the metal is thinner. With nonstick baskets, I always had to rotate the food halfway through. With the steel tray, I rarely need to.
How to Use Stainless Steel Air Fryer Trays Without Sticking
Pre-Season the Tray Before First Use
Stainless steel is not naturally nonstick. If you put raw chicken directly on a clean, dry steel tray and air fry it, the protein will bond to the surface. You need to create a barrier. The easiest method is to rub the tray with a very thin layer of high-smoke-point oil — avocado oil or grapeseed oil work well — then heat the empty tray in the air fryer at 400°F for 10 minutes. This polymerizes a thin layer of oil onto the steel, similar to seasoning a cast iron pan.
After that initial seasoning, apply a fresh drop of oil before each use. Use a paper towel to wipe it into a film so thin you can barely see it. That layer is enough to release most foods.
Adjust Cooking Times and Temperatures
Because stainless steel retains heat longer than aluminum, your food may cook slightly faster once the tray is hot. Drop the temperature by 25°F from your usual recipe and check for doneness two minutes early. You can always add time, but you cannot undo overcooked food.
For frozen foods like french fries or chicken nuggets, spread them in a single layer and do not overcrowd. The steel tray conducts heat into the underside of each piece. If the pieces overlap, the contact area stays cool and the food steams instead of crisping.
Use Parchment Paper as a Backup
If you are cooking something very sticky — marinated tofu, glazed meatballs, or cheese-filled items — place a sheet of parchment paper on the tray. Cut it to size so it does not block airflow. The paper prevents direct contact while still allowing hot air to circulate. Do not use wax paper or regular baking paper; they will burn. Use unbleached parchment rated for at least 425°F.
Cleaning and Maintenance That Extends Tray Life
Clean While Warm, Not Hot
Let the tray cool for about five minutes after cooking. Then rinse it under hot tap water. The thermal shock of cold water on hot steel can warp thin trays over time. Use a stiff nylon brush — not steel wool — to dislodge stuck bits. If food is stuck, fill the tray with hot water and a drop of dish soap and let it soak for 15 minutes. The residue will loosen without scrubbing.
Avoid Dishwasher Detergents with Chlorine
Most stainless steel trays are dishwasher safe, but the high heat and harsh detergents can dull the finish over months of repeated cycles. If you use a dishwasher, choose a detergent without chlorine bleach. Chlorine can pit stainless steel, creating tiny rough spots where bacteria can hide. Hand washing with a mild soap and a soft sponge preserves the surface longer.
Remove Discoloration with Vinegar
Stainless steel develops a rainbow tint or brown spots after high-heat use. That is not rust. It is a thin oxide layer caused by heat. To remove it, wipe the tray with white vinegar on a soft cloth, then rinse and dry immediately. For stubborn marks, make a paste of baking soda and water, scrub gently, and rinse. Never use oven cleaner or bleach-based products.
Comparing Stainless Steel Trays to Other Air Fryer Accessories
Stainless Steel vs. Nonstick Baskets
Nonstick baskets are easier to clean initially, but the coating degrades within 6 to 12 months of regular use. Once the coating is damaged, you must replace the basket. Stainless steel trays do not degrade. They may discolor, but that does not affect performance. The trade-off is that stainless steel requires a bit more effort to prevent sticking — a small price for longevity.
Stainless Steel vs. Silicone Mats
Silicone mats are flexible, nonstick, and easy to clean, but they insulate the food from the hot metal. Air fryers work by circulating hot air around the food, but the tray itself also conducts heat into the bottom of the food. Silicone blocks that conductive heat transfer. You get less browning on the underside. Stainless steel maintains both convective and conductive heating, giving you a more even crust.
Silicone mats also have a lower maximum temperature — usually around 450°F. Stainless steel handles 500°F or higher without issue. If you like to air fry at high temperatures for pizza or roasted vegetables, steel is the better choice.
Stainless Steel vs. Aluminum Pans
Aluminum heats up faster and is lighter, but it reacts with acidic foods like tomatoes or citrus. The metal can leach into the food, giving it a metallic taste. Stainless steel is non-reactive. You can cook a tomato-based sauce or marinate chicken in lemon juice directly on the tray without flavor changes. Aluminum also warps more easily under high heat. Stainless steel holds its shape.

Practical Recipes That Work Better on Steel Trays
Crispy Chicken Wings
Pat the wings dry with paper towels. Toss them with a teaspoon of baking powder (not baking soda) and salt. The baking powder raises the pH of the skin, helping it brown faster. Arrange the wings on the preheated stainless steel tray in a single layer. Air fry at 400°F for 25 minutes, flipping once at the 15-minute mark. The steel tray ensures the undersides crisp just as much as the tops.
Roasted Vegetables with Caramelized Edges
Cut vegetables like broccoli, cauliflower, or Brussels sprouts into uniform pieces. Toss with oil and salt. Spread on the stainless steel tray. Air fry at 375°F for 12 to 15 minutes. Because stainless steel holds heat, the vegetables get a deep brown color on the cut sides without burning the florets. Nonstick baskets often leave the cut sides pale.
Reheating Pizza
Place the pizza slice directly on the stainless steel tray. Air fry at 350°F for 3 to 4 minutes. The steel conducts heat into the crust, making it crispy again, while the hot air re-melts the cheese. A microwave ruins pizza texture. A steel tray in an air fryer restores it.

Frequently Asked Questions
Can I put stainless steel air fryer trays in the dishwasher?
Yes, most stainless steel trays are dishwasher safe, but hand washing is better for preserving the finish. If you use a dishwasher, select a cycle without high heat drying and use a detergent without chlorine bleach. Dry the tray immediately after the cycle ends to prevent water spots.
Do stainless steel air fryer trays cause food to stick more than nonstick?
They can, if you do not prepare them properly. The key is to preheat the tray, apply a thin layer of oil, and avoid overcrowding. Once you develop the habit of seasoning the tray like a cast iron pan, sticking becomes rare. Foods with high sugar content, like glazed meats, still benefit from a sheet of parchment paper.
Are stainless steel air fryer trays safe at high temperatures?
Yes. Food-grade stainless steel (typically 304 or 18/8 grade) is safe up to about 500°F. Most air fryers do not exceed 450°F, so the tray is well within its operating range. Do not heat an empty tray on an open flame or in a broiler unless the manufacturer explicitly states it is broiler-safe.
How do I remove burnt-on food from a stainless steel tray?
Fill the tray with hot water and a tablespoon of baking soda. Let it soak for 20 minutes. The alkaline water helps break down the burnt proteins. Scrub with a nylon brush. If residue remains, make a paste of baking soda and a few drops of water, apply it to the spot, and let it sit for 10 minutes before scrubbing again. Avoid abrasive pads that scratch the surface.
