• GSZN 8QT — biggest strength: it's a purpose-built square crisper plate for one machine, the Gourmia GAF856 8QT air fryer, made from food-grade carbon steel with a double-layer nonstick coating and a handle for lifting it out.
• GSZN 8QT — biggest trade-off: it isn't a general-purpose pan. If you don't own that specific air fryer, or you want to cook on a stove top, it has no job in your kitchen.
• Kordisen — biggest strength: it's a full 11-inch square grill pan with a lid, pour spouts, raised ridges and a magnetic stainless steel base that works on induction and other stove tops, plus frying, baking and griddling.
• Kordisen — biggest trade-off: it's a hefty 4.7-pound piece of cookware that needs a heat source and stovetop space, and it does nothing for your air fryer.
• Who each pick is for: GSZN 8QT for Gourmia GAF856 owners who want crisp results with less cleanup; Kordisen for anyone who wants one pan that grills, sears, sautés and bakes across a stove, an oven or a grill.
The GSZN 8QT is a replacement crisper tray, not a pan in the traditional sense. It measures about 8.3 x 8.3 inches and sits inside the basket of a Gourmia GAF856 Digital 8QT Air Fryer, lifting food off the base so hot air can circulate underneath. That airflow is the whole point of an air fryer grill pan — it's what separates a soggy bottom from a properly crisped one.
The build is food-grade carbon steel with a double-layer nonstick coating that the brand describes as high-temperature resistant and resistant to flaking. There's a handle so you can pull the hot tray straight out of the basket, and it's dishwasher safe. GSZN also throws in eight silicone rubber feet and a nonstick cleaning cloth, and notes that you should adjust the tightness of the four feet to get a snug fit in your specific fryer.
Buy it if you own the Gourmia GAF856 8QT and want to cook wings, fries, vegetables or reheated leftovers with better browning and an easier cleanup than a bare basket. Skip it if you own a different air fryer model, or if you're looking for cookware you can put on a burner — this tray only makes sense inside that one machine.
One practical note from the spec sheet: don't scrub it with abrasive pads or metal balls, because that's exactly what kills a nonstick coating. The included cloth exists for that reason.
The Kordisen is the opposite kind of product: a real piece of cookware. It's an 11-inch square grill pan made from aluminum with a granite-style nonstick coating that the brand says is SGS verified and free of PFOA and PFOS. It weighs 4.7 pounds, which tells you it's a substantial pan with some thermal mass rather than a flimsy sheet.
The design details are what make it interesting. Raised ridges give you grill marks and lift food out of its own fat, and two tilted pour spouts let you tip that fat off into a cup or sink instead of pooling it around your steak. The high magnetic conductive stainless steel base is built for even, rapid heat distribution and makes the pan compatible with induction as well as standard electric and gas stove tops. It ships with a lid and a pair of tongs.
Buy it if you want one pan for searing steaks, griddling pancakes or eggs, sautéing vegetables, pan-frying fish and baking — indoors on a stove or oven, or outdoors on a camp stove or grill. Skip it if your goal is air frying. A stove-top grill pan and an air fryer basket do genuinely different jobs, and the Kordisen has no role inside an air fryer.
• Best for air frying → GSZN 8QT. It's engineered to sit inside a Gourmia GAF856 8QT basket and improve airflow under the food.
• Best for stove-top searing → Kordisen. The magnetic stainless steel base and 11-inch ridged surface are built for burners, including induction.
• Best for grill marks and fat drainage → Kordisen. Raised ridges plus dual tilted pour spouts are a combination the GSZN simply doesn't have.
• Best for easy cleanup → GSZN 8QT. The nonstick tray is dishwasher safe, which is about as low-effort as cleanup gets.
• Best for cooking a full meal for two or more → Kordisen. An 11-inch square surface holds multiple steaks, a batch of vegetables or a stack of pancakes; the GSZN tray is sized to one air fryer basket.
• Best for versatility across heat sources → Kordisen. Stove top, oven and outdoor use are all listed; the GSZN only works in one specific air fryer.
• Best for a single-purpose upgrade → GSZN 8QT. If your only complaint is that your air fryer food isn't crisp enough, this is the targeted fix.
• Best if you own a different air fryer brand → neither, strictly speaking. The GSZN is specified for the Gourmia GAF856, and the Kordisen isn't an air fryer accessory at all.
My Verdict
In my opinion, these aren't really competitors — they're two answers to two different questions, and the right buy depends entirely on what's already on your counter.
If you own a Gourmia GAF856 8QT and your frustration is uneven browning and scrubbing a basket, I'd buy the GSZN 8QT. It's the more focused purchase, and it solves a specific, recurring annoyance.
If you don't own that air fryer, or you want cookware that earns its space across steaks, eggs, pancakes and vegetables, I'd buy the Kordisen Nonstick Grilling Pan. It's heavier, more versatile and does more jobs — just not the air fryer one.
how to clean ninja air fryer grill pan
The principle is the same for any air fryer grill pan, including the GSZN: let it cool, then wash it in warm soapy water or put it in the dishwasher. Avoid abrasive pads and metal scouring balls, because they strip the nonstick coating. The GSZN is dishwasher safe per its spec sheet and ships with a dedicated nonstick cleaning cloth.

A grill pan insert sits in the air fryer basket and lifts food off the base so hot air circulates underneath and around it. Set your food on the tray in a single layer, leave gaps for airflow, and shake or flip halfway. Note that the GSZN is specified for the Gourmia GAF856 8QT, so check fitment before buying for another brand.

Neither data sheet lists cooking times, so I won't invent one — timing depends on your air fryer, the thickness of the pieces and how browned you want them. The general approach is a single layer on the grill pan, a shake or flip partway, and checking early the first time you make it. A grill pan insert mainly helps by giving you better browning and less sticking.
It depends on the result you want. The Kordisen's raised ridges and 11-inch surface are designed for real searing on a stove top with fat draining off through the pour spouts. An air fryer grill pan like the GSZN is better for smaller portions and hands-off cooking with easy cleanup. For a thick steak with a hard crust, I'd reach for the Kordisen.
