Air fryer accessories for Cosori models fall into a few clear categories. You need items that fit the specific basket dimensions of your machine, withstand temperatures up to 400°F, and allow hot air to circulate freely. The most common add-ons include silicone liners, perforated parchment rounds, wire racks, grill pans, and skewer sets.
Choosing the right ones depends entirely on which Cosori model you own and what you cook most often.
This guide breaks down the main types of air fryer accessories for Cosori baskets. It covers sizing differences between the popular 5.8-quart and 6.8-quart models, explains which materials hold up over time, and points out where cheap third-party options fall short. If you just bought your machine or want to stop scrubbing baked-on grease every night, this tells you exactly what fits and what doesn't.
Why Basket Size Dictates Every Purchase
Cosori makes several air fryer sizes. The 3.7-quart, 5.8-quart, and 6.8-quart dual-blaze models are the most common in kitchens. An accessory designed for one will not work properly in another.
A liner that is too large folds up the sides and blocks the heating element. One that is too small leaves gaps where grease pools and burns against the nonstick coating.
Before buying anything, measure the flat bottom of your specific basket. The 5.8-quart square basket measures roughly 9 inches across. The 6.8-quart model is closer to 10 inches.
Round baskets require round accessories, while the square Cosori models need square or specifically shaped rectangular inserts. Third-party sellers often list "universal" sizes. These rarely sit flush in a Cosori basket.
Stick to measurements rather than generic labels.
Using an ill-fitting insert also changes how heat moves through the chamber. Cosori designs its baskets with specific airflow patterns. Blocking those vents with an oversized silicone mat forces the fan to work harder and cooks food unevenly.
The FDA regulates food contact materials like silicone and parchment, so verify that any third-party insert carries proper safety certifications before it touches your dinner.
Silicone Liners That Actually Fit Cosori Baskets
Silicone liners are the most popular purchase. They catch drips, prevent sticking, and save you from scrubbing the nonstick basket after every meal. For Cosori machines, you need a liner with raised edges to contain liquids and a flat bottom that matches your basket shape.
Thick, food-grade silicone rated for at least 450°F works best. Thin silicone warps when the fan blows hot air across it. A warped liner lifts off the bottom, lets grease slide underneath, and defeats the whole purpose.
Look for liners with small ridges or grooves on the bottom. These keep the silicone slightly elevated so air still moves beneath your food.
The tradeoff with silicone is browning. Food sitting in a solid silicone cup won't crisp on the bottom the way it does directly on the wire rack. If you want maximum crunch, silicone isn't the right choice for every meal.
I find it works perfectly for reheating leftovers or cooking saucy dishes, but raw chicken wings need direct airflow. When you do want that deep browning on poultry, following a tested method to get extra crispy skin matters more than relying on a liner to do the work.
Many people buy multi-packs online. Check the reviews specifically from Cosori owners. A liner marketed for round Philips or Ninja baskets will bunch up in a square Cosori drawer.
Perforated Parchment Rounds vs Solid Paper Liners
Parchment paper is cheaper than silicone and disposable. For air frying, you must use perforated parchment. Solid sheets block the fan's airflow completely.
This causes the heating element to overheat and can trigger the machine's automatic shutoff.
Pre-cut perforated parchment rounds or squares made for air fryers have dozens of small holes punched through them. These let hot air pass through while catching crumbs and light grease. They are ideal for breaded foods or sticky marinades.
If you plan to soak your chicken in a wet flavorful brine or glaze beforehand, parchment keeps the sugars from burning directly onto the metal grate.
Never preheat the Cosori with parchment inside and no food on top. The fan will blow the lightweight paper up into the heating coil, and it will burn. Always weigh the paper down with food before turning the machine on.
One limitation of parchment is single use. You throw it away after every batch. Over a year, that cost adds up compared to a reusable silicone mat.
But for avoiding cross-contamination between raw meat and vegetables cooked back-to-back, disposable paper is faster.
Stacking Racks for Cooking Two Layers at Once
A stainless steel wire rack lets you stack food vertically. This doubles your capacity without buying a larger machine. Cosori sells official racks for some models, and third-party options exist as well.
The rack needs feet tall enough to clear the food on the bottom layer. If the gap is too tight, the bottom layer steams instead of crisping. For a 5.8-quart Cosori, a rack with 1.5-inch legs usually provides enough clearance for things like fries or vegetable chunks.
Larger cuts of meat need more room.
Stainless steel is the only material to consider here. Chrome-plated wire can chip under high heat and repeated scraping. Bare steel rusts after a few washes.
Make sure the rack is labeled dishwasher safe, because hand-washing greasy wire grids is tedious.
Stacking racks work well for uniform foods. They fail when you mix items with different cook times. If you're doing heavy batch cooking for the week, stacking identical proteins on two levels saves significant time.
Just remember to swap the top and bottom layers halfway through the cycle for even browning.
Grill Pans and Crisper Plates
Some Cosori models ship with a basic crisper plate. Replacements or upgraded grill pans give you distinct sear marks and lift fat away from the food. A grill pan accessory typically has raised ridges cast into the metal.
These pans must be made of materials that handle rapid temperature changes. Cast aluminum heats fast and distributes evenly. Nonstick coatings on grill pans wear out faster than bare metal because spatulas scrape the ridges during flipping.
If you buy a nonstick grill pan for your Cosori, use only silicone tongs.
A dedicated grill pan takes up the entire basket footprint. You lose the ability to shake the basket mid-cook. Foods that need tossing, like diced potatoes, don't belong on a fixed grill pan.
Reserve this accessory for steaks, chops, or thick fish fillets that stay in one place.
Skewer Sets Designed for Square Drawers
Kebab skewers made for air fryers are shorter than standard grill skewers. They rest horizontally across the basket or hang from a central ring if your Cosori model supports a rotisserie function.
For square basket models like the 5.8-quart, straight metal skewers that lay flat work best. The length must be under 9 inches to fit without hitting the walls. Stainless steel skewers with flat blades prevent round foods like cherry tomatoes from spinning when you try to turn them.
Wooden bamboo skewers can be used in a Cosori, but they require soaking in water for 30 minutes first. Even soaked, the tips char quickly near the heating element. Metal is a safer, longer-lasting choice for frequent use.
Skewers are great for vegetables and small meat pieces. They aren't practical for heavy loads. Thick chunks of pork shoulder pull the skewers down, causing them to rest on the basket floor and block airflow underneath.
Thermometers That Survive the Airflow
You cannot leave a standard plastic-handled thermometer inside a running Cosori. The concentrated heat and powerful fan will melt handles or blow lightweight probes around the chamber. However, checking internal temperatures remains necessary for food safety.
The USDA recommends cooking all poultry to 165°F, and guessing by color alone leads to dry or unsafe results.
If you want to monitor food without opening the drawer constantly, look into a reliable wireless probe setup where the transmitter sits outside the unit. Some users route thin probe wires through the vent gaps, though this requires caution to avoid pinching the cord when closing the drawer. Alternatively, keeping a fast instant-read tool nearby means you only open the basket for two seconds to check the temp.
Opening the drawer drops the internal temperature rapidly, so speed matters.
Knowing your final target temperature also helps you track overall intake if you're watching total calories per serving. Pulling the meat at exactly 165°F prevents the moisture loss that happens when you accidentally overcook it to 180°F while fumbling for a reading.
Comparing Accessory Materials and Heat Limits
Different materials behave differently inside a Cosori. Choosing the wrong one leads to melted plastic, chipped coatings, or restricted airflow. Here is how the common materials compare when exposed to typical air frying conditions.
| Material | Max Safe Temp | Durability | Airflow Impact | Best Used For |
|---|---|---|---|---|
| Food-grade Silicone | 450°F | High (years) | Low (blocks bottom air) | Sauces, reheating, easy cleanup |
| Perforated Parchment | 425°F | Single use | Medium (holes allow flow) | Breaded items, sticky glazes |
| Stainless Steel | 600°F+ | Very High | High (open wire design) | Stacking racks, skewers, grilling |
| Nonstick Aluminum | 400°F | Medium (coating chips) | Varies by design | Grill pans, baking trays |
| Bamboo Wood | 350°F (soaked) | Low (chars easily) | N/A | Light skewers only |
Silicone lasts the longest but sacrifices bottom crispness. Stainless steel gives the best airflow but requires washing immediately to prevent stuck-on carbon. Parchment offers convenience at the cost of recurring purchases.
Match the material to the specific dish you plan to cook rather than buying one type for everything.
Official Cosori Kits vs Third-Party Bundles
Cosori sells branded accessory kits directly. These usually include a pizza pan, a cake barrel, a metal rack, and silicone mats sized precisely for their machines. The guarantee is fit.
You don't have to measure or guess.
Third-party bundles on major retail sites offer 10 to 15 pieces for a lower total price. The catch is inconsistent sizing. A "universal" 8-inch pan might rattle around in a 9-inch square drawer.
The silicone molds might smell strongly of chemicals during the first three uses, indicating lower-grade materials.
If you only need one specific item, like a replacement crisper plate, buy the official Cosori part. If you want to experiment with baking cakes or making pizza in the fryer, a third-party bundle gives you variety without spending heavily on each piece. Just verify the dimensions against your specific model number before clicking buy.
Reading user manuals matters here. Cosori specifies which accessories are safe for their heating elements. Using an unapproved pan that reflects too much heat upward can damage the top coil over time.
Cleaning and Maintaining Your Inserts
Accessories extend the life of your Cosori basket, but only if you maintain them properly. Grease builds up on wire racks and silicone liners just as fast as it does on the main drawer.
Silicone absorbs odors if left unwashed. Soaking liners in warm water with baking soda removes lingering smells from garlic or fish. Avoid abrasive scouring pads on nonstick grill pans.
Once the coating scratches, food bonds to the bare metal underneath.
Wire stacking racks need attention at the weld points. Grease hides in the joints where the feet attach to the grid. A stiff nylon brush reaches these spots better than a sponge.
Run racks through the dishwasher on the top rack only. The bottom heating element in some dishwashers gets hot enough to discolor thin steel.
Parchment is disposable, but don't compost wax-coated versions. Only unbleached, unwaxed perforated paper belongs in a compost bin.
Edge Cases Where Standard Add-Ons Fail
Not every recipe works with accessories installed. Large whole chickens take up the entire 5.8-quart cavity. Adding a rack or liner leaves no room for the bird to sit below the heating element safely.
Cook large roasts directly on the factory crisper plate.
Wet batters drip through wire racks and pool at the bottom, creating smoke. If you are frying battered fish, use a solid silicone liner or skip the accessory entirely and clean the basket afterward.
Dehydrating fruit requires maximum airflow. Placing a silicone mat underneath fruit slices traps moisture and slows the drying process significantly. Remove all solid barriers when using the dehydrate function on compatible Cosori models.
Finally, if you switch between cooking styles frequently, swapping accessories mid-session wastes time. Plan your cook order. Do the messy, saucy items first with a liner, then remove it for dry-roasting vegetables that need direct heat.
Pairing your finished protein with a quick acidic or creamy dip right after it rests makes the extra planning worth the effort.
Frequently asked questions
Can I use regular oven pans inside my Cosori?
Only if they fit without touching the walls or the top heating element. Standard quarter-sheet pans are too large for most Cosori baskets. Small, round cake pans or ramekins made of oven-safe ceramic or metal work, provided they leave at least an inch of space around the edges for air circulation.
Do silicone liners cause the air fryer to smoke?
They shouldn't, unless grease pools in the liner and splashes up toward the heating coil. Smoking usually happens when oil hits the top element. A properly fitted silicone liner catches drips and actually reduces smoking compared to cooking directly on a dirty basket grate.
Is parchment paper safe at 400 degrees?
Most parchment paper is rated for 425°F to 450°F. At 400°F, it is perfectly safe as long as it is weighed down by food. Loose parchment will fly into the heating element and ignite.
Always use perforated sheets designed for air fryers rather than solid baking parchment.
Will aftermarket racks void my Cosori warranty?
Using third-party accessories does not automatically void the warranty. However, if a poorly fitting metal rack scratches the nonstick coating or reflects heat that damages the element, Cosori may deny a claim based on improper use. Stick to recommended sizes and materials to protect both the machine and your coverage.
How do I choose between a silicone mat and a grill pan?
Pick silicone for easy cleanup and cooking liquid-heavy foods like marinated meats or reheated casseroles. Pick a grill pan when you need sear marks, fat drainage, and maximum crispness on dry-rubbed proteins. You can't get a hard crust through a thick silicone barrier.
Are bamboo skewers safe in a Cosori?
They are safe only if soaked in water for at least 30 minutes before cooking, and kept away from the direct path of the top heating element. Even when soaked, the exposed ends will char. Stainless steel skewers are a much safer and more durable option for enclosed air fryer baskets.
Getting the Right Fit for Your Machine
Buying air fryer accessories for Cosori machines comes down to measuring your basket and matching the material to your cooking style. Don't grab a universal kit hoping everything fits. Check the exact dimensions of your 3.7, 5.8, or 6.8-quart model first.
Prioritize perforated parchment for crispness, silicone for easy cleanup, and stainless steel for stacking. Keep the airflow paths clear, respect the temperature limits of each material, and your Cosori will last far longer than it would taking daily abuse from stuck-on grease.
