The era of the single-basket air fryer is rapidly fading into the background of my kitchen pantry. Over the last month, I’ve been living with the two most innovative “large-format” air fryers on the market: the Cosori TwinFry 9Qt and the Ninja Foodi FlexDrawer (DZ071). These aren’t just air fryers; they are full-blown meal coordination centers.
Testing these units side-by-side felt like a high-stakes cooking show in my own home. One day I was trying to sync salmon and asparagus to finish at the exact same moment, and the next I was attempting to fit a whole pork roast into a single massive zone. While both machines promise to solve the “back-to-back cooking” problem, they go about it in fundamentally different ways—one through dedicated separation and the other through sheer mechanical flexibility.
The Key Difference: Fixed Separation vs. The MegaZone
The most critical key difference between the Cosori TwinFry and the Ninja FlexDrawer is how they handle their internal space. The Cosori TwinFry is a dedicated dual-basket system, featuring two independent 4.5-quart baskets. It is designed for total flavor isolation—seafood in one, veggies in the other—ensuring no mixed aromas.
The Ninja FlexDrawer, however, features a revolutionary “FlexBasket” design. It uses a single 7-quart drawer with a removable divider. This allows you to switch between two 3.5-quart zones or one massive “MegaZone.” While the Ninja offers less total capacity (7 quarts vs. Cosori’s 9 quarts), its ability to transform into one large open space makes it the only choice for oversized proteins like a 4-lb pork roast or a whole chicken that wouldn’t fit in a divided basket.

Detailed Comparative Review: My Kitchen Experience
Design and Footprint: Deep vs. Wide
The first thing I noticed when clearing counter space was the orientation. The Cosori TwinFry is a deep machine (17.3 inches). It juts out further from the wall but feels more “upright.” The Ninja FlexDrawer is significantly wider (over 18 inches) but shallower.
In my kitchen, the Ninja actually felt like it took up more “active” space because it occupies a larger horizontal stretch of the countertop. However, the Ninja’s drawer design is incredibly satisfying to use. Pulling out one massive 7-quart drawer feels more substantial than the two smaller drawers of the Cosori. The Cosori, however, wins on the material feel; the aluminum and non-stick components felt a bit more premium than the primarily plastic build of the Ninja.

Performance: The Searing and Steaming Test
I tested both units with a “Balanced Dual-Basket” meal: steak in one side and broccoli in the other.
- Cosori TwinFry: This machine is a powerhouse for browning. I hit the 450°F Max Crisp setting for the steak, and because the 4.5-quart baskets are relatively contained, the heat concentration was intense. The steak had a genuine crust while the broccoli stayed vibrant. The “No Mixed Flavors” claim held up; my broccoli didn’t smell like ribeye.
- Ninja FlexDrawer: The Ninja also hits 450°F on the “Air Broil” setting. The results were equally crispy, but I noticed that because the divider is removable, there is a tiny bit of air/aroma bleed between the two 3.5-quart zones. It wasn’t a dealbreaker, but the Cosori definitely provides a more “airtight” separation for distinct flavors.
- FLEXBASKET: Use the divider to cook with two 3.5 qt baskets for foods that require different cooking times or temps or remove it to have 1 MegaZone for full 7 qt...
- 7 QT MEGAZONE: Unlocks the ability to cook larger proteins and meals that feed your whole family all in one basket.
Capacity: The MegaZone Advantage
This is where the Ninja FlexDrawer reclaimed the lead. Last Sunday, I wanted to cook a 4-lb pork roast with baby potatoes. In the Cosori, I would have had to cut the roast in half to fit it into the 4.5-quart baskets. In the Ninja, I simply pulled out the center divider and utilized the 7-quart MegaZone.
The MegaZone is a game-changer for anyone who finds dual-basket air fryers too “fiddly” for big family roasts. Even though the Cosori has 2 quarts more total volume, the Ninja’s contiguous space is often more useful for large, odd-shaped items.
Ease of Use: Syncing the Meal
Both machines have mastered the art of the “Sync Finish.” I programmed both to cook fries (longer time) and chicken tenders (shorter time). Both the Cosori and the Ninja held back the shorter-cooking item and started it exactly when needed so both were piping hot at the same second.
The Cosori interface feels a bit more “tech-forward” with 10 functions including “Shake” reminders and “Preheat” (which I highly recommend using for better browning). The Ninja is more “manual” in its feel, which some may prefer for its simplicity. The Cosori’s inclusion of 130 recipes (compared to Ninja’s 20) also made me feel more adventurous with my meal planning.

Cleanup
Both units claim to be dishwasher safe, and I put that to the test.
- Cosori: Having two separate baskets is actually easier for the dishwasher. They fit into the bottom rack like large bowls.
- Ninja: The 7-quart FlexBasket is a huge piece of equipment. It took up nearly half of my bottom dishwasher rack. If you have a smaller dishwasher, you will almost certainly be hand-washing the Ninja drawer. Luckily, the non-stick coating on both is excellent, and a quick wipe-down usually does the trick.

Ninja FlexDrawer 7Qt Air Fryer
- FLEXBASKET: Use the divider to cook with two 3.5 qt baskets for foods that require different cooking times or temps or remove it to have 1 MegaZone for full 7 qt...
- 7 QT MEGAZONE: Unlocks the ability to cook larger proteins and meals that feed your whole family all in one basket.
Pros:
- FlexBasket Versatility: The removable divider is the best of both worlds.
- MegaZone: The 7-quart open space is perfect for large proteins and sheet-pan style meals.
- Air Broil: High-heat 450°F setting provides a perfect charred finish.
- Faster Cooking: Dual fans help circulate air 40% faster than a traditional oven.
Cons:
- Smaller Total Volume: 7 quarts is significantly less than Cosori’s 9 quarts.
- Bulky Drawer: The single large drawer is harder to fit in a dishwasher.
The Verdict: My Recommendation
I recommend the Cosori TwinFry 9Qt if you are a family that prioritizes variety and volume. If you frequently cook a main and a side (like fish and chips or chicken and broccoli) and you want the most total space possible, the 9-quart capacity and the 10-in-1 functions make this a superior “meal prep” machine. It’s also the better choice for fitness enthusiasts who want to cook bulk proteins and veggies separately without flavor crossover.
I recommend the Ninja FlexDrawer if you want the flexibility to replace your traditional oven. The “MegaZone” is the star here. If you find yourself frustrated by the small baskets of traditional dual-zone fryers, the Ninja’s ability to transform into a single large cooking cavity is worth the sacrifice of 2 quarts of total volume.
For my lifestyle, the Ninja FlexDrawer wins. The ability to pull that divider out and roast a whole bird or a large tray of nachos in the MegaZone is a level of flexibility I find myself using more often than the extra capacity of the Cosori.

Frequently Asked Questions (FAQs)
Q: Can I cook at two different temperatures in the Ninja FlexDrawer?
A: Yes! As long as the divider is in place, you can set Zone 1 to 400°F and Zone 2 to 350°F, and use “Smart Finish” to make sure they end at the same time.
Q: Does the Cosori TwinFry require preheating?
A: It has a dedicated “Preheat” button, and while it’s not strictly mandatory, I found that using it resulted in much crispier results for frozen foods and better searing on steaks.
Q: Is the divider in the Ninja FlexDrawer airtight?
A: Not perfectly. There is a slight gap to allow for the drawer to slide in and out easily. While it keeps the food separate, you might notice some steam or aroma moving between the zones.
Q: Can I fit the Cosori baskets in a standard sink?
A: Yes, the 4.5-quart baskets are roughly the size of a large toaster oven pan and are very easy to wash by hand in a standard sink.
