This flexible air fryer covers single and dual-zone cooking - it's non-toxic too

The Cosori Dual Blaze TwinFry Air Fryer is, in my opinion, one of the most exciting launches in the category this year. Take it from me, an unapologetic air fryer geek, Cosori consistently produces some of the best models on the market, and this one absolutely earns its place among the best air fryers. Flexible, fast, and engineered with finesse and real attention to detail, it’s designed to handle everything from midweek dinners to full-scale family cooking.

You’ll have seen plenty of brands moving in the same direction, especially competitors like the Ninja Foodi FlexDrawer, but Cosori’s execution is particularly refined. This is an air fryer that can transform from a generous 10L “grandzone” for roasting a whole chicken into two independent cooking zones for entirely different dishes.

Combine that clever architecture with Cosori’s reputation for reliability and thoughtful design, and you have a seriously capable machine. I’ve been putting it through its paces in our test kitchen and, genuinely, I’m impressed.

Who would the Cosori Dual Blaze TwinFry Air Fryer suit?

You might recognise the design of the Cosori Dual Blaze TwinFry Air Fryer: the Ninja FlexDrawer and Tower Elite Flexi-Drawer both work on the same principles. It can be one large, single-drawer air fryer or work as a dual-drawer air fryer for busy homes. Cosori has incorporated smart functions, an app compatibility, and their own signature design quirks, but this is, in essence, a versatile, family-friendly air fryer.

As an air fryer that's best suited to big homes and substantial servings, it's one of the more expensive models on the market. Whilst it is an investment, it feels like one of the more robust models: the drawer can sit inside the air fryer comfortably when you've cooked (rather than leaving it on a surface while it's boiling), it doesn't need to be shaken half way through, and you can leave it running for up to 48 hours on a low and slow cook (which is helpful for the drying function). It's worth the investment and is often on offer too, so keep your eyes peeled for a saving.

You might recognise the format of the Cosori Dual Blaze TwinFry Air Fryer. Designs like the Ninja FlexDrawer and Tower Elite Flexi-Drawer follow a similar principle, shifting between a single large zone and dual cooking zones. Cosori builds on this with smart connectivity, intuitive programming, and a polished finish that looks and feels premium.

This is an air fryer that really comes into its own in larger households or for anyone who cooks in generous quantities. If you like batch cooking, hosting, or simply want to streamline dinner without juggling multiple appliances, it makes a compelling case. It’s also one of the best non-toxic air fryer options available right now, thanks to its ceramic-coated, PFAS-free interior, which will matter to anyone trying to make more considered choices in the kitchen.

That being said, there’s no getting around the fact that this is an investment piece. It's larger than other models (something to keep in mind if you have a compact kitchen) and not as cheap as other models. It justified the price with neat features, such as the stable drawer, the dual heating elements that remove the need for shaking, and the low-and-slow function can run for up to 48 hours, which is really useful for dehydrating. If you’ve been researching what you need to know before buying an air fryer, this is a model that shows what the top end of the market can do. It’s also frequently discounted, so it’s worth keeping an eye out for some air fryer deals.

Unboxing the Cosori Dual Blaze TwinFry

True to its promise, the Cosori Dual Blaze TwinFry Air Fryer arrives in a substantial box, and thankfully, Cosori has clearly thought about the logistics. Sturdy side handles make it far easier to manoeuvre than you’d expect for something this size.

Inside, the attention to detail continues. You’ll find a beginner-friendly guide that neatly covers how to use an air fryer, alongside a detailed cooking chart that helps you calibrate time and temperature across different ingredients. Cosori also includes rubber-tipped tongs, which might sound like a small addition, but they’re one of my most-used air fryer accessories. You'll quickly realise you can’t live without them, because they protect the non-stick coating and make turning food far less messy.

If I’m being critical, there’s still some soft plastic packaging inside, which feels slightly at odds with an otherwise thoughtful product. The main box is recyclable, and the plastics can be recycled at larger supermarkets, but I would have liked to see Cosori go a step further here.

What is the Cosori Dual Blaze TwinFry like to use?

Despite the inclusion of a beginner’s guide, the Cosori Dual Blaze TwinFry Air Fryer is intuitive from the moment you switch it on. The digital interface clearly displays temperature, time, and pre-sets, as well as options for switching between zones or synchronising cooking times, which feels seamless. You can match both zones or stagger them so everything finishes together, which is an air fryer hack that makes a big difference during busy evenings.

The cooking modes cover all the essentials, including air fry, roast, bake, and grill, alongside a dehydration function that can run continuously for up to 48 hours. What sets this model apart is the dual heating element system, which circulates heat from both above and below, eliminating the need to shake or turn food midway through. That alone helps you avoid one of the most common air fryer mistakes and frustrations.

I started with a classic chip test, cooking frozen chips at 200°C using the preset 25-minute programme. At first, that timing felt conservative, so I checked at intervals from 15 minutes onwards. As it turns out, Cosori’s calibration was spot on. At 25 minutes, the chips were evenly golden with a crisp exterior and a fluffy centre, with no need for shaking. The heat distribution was impressively consistent across the entire basket.

Next, I tested twelve frozen fish fingers at 180°C. While standard guidance suggests 12 to 15 minutes, I extended this to 18 minutes in line with the Cosori’s cooking profile.

The result was a full box of fish fingers that turned out crisp on the outside and fully heated through. I’d likely shave a couple of minutes off next time for a slightly lighter finish, as you can see that some were nudging their way towards looking a little dark. Even so, it comfortably outperformed a conventional oven in both speed and texture. And, I managed to fit 12 fish fingers in just one half. I think you could comfortably cook 26 fish fingers in a whole drawer, if the fancy took you.

The grill function is another area where this model shines. I cooked Mediterranean vegetables at 200°C, and the results were exactly what you want from a proper grill. The onions caramelised at the edges, softened in the centre, and developed just enough charring to add depth without tipping into sogginess.

Reheating is often overlooked, but it’s a brilliant test of temperature control. I reheated leftover pizza at 180°C for 10 minutes. The base regained its crispness, the crust stayed soft, and the toppings retained their moisture and flavour. In dual-zone mode, I could reheat half a pizza while cooking chips alongside it. Removing the divider allowed me to fit an entire 12-inch pizza, albeit sliced in half. If you want a full, round pizza, you might need to look at more square, air fryer ovens.

For baking, I opted for a lemon and blueberry loaf, cooked at 160°C for a longer, gentler bake. The rise was even, the crumb was light, and the top developed a consistent golden colour. It’s a strong reminder that this isn’t just an air fryer for your quick meals and frozen foods, it could replace your oven, especially if you're conscious of your bills.

Cleaning the Cosori Dual Blaze TwinFry Air Fryer

Cleaning the Cosori Dual Blaze TwinFry Air Fryer is, thankfully, rather straightforward. If you’re familiar with how to clean an air fryer, you’ll know that non-stick quality makes all the difference, and here it really delivers. The grease and residue slid out of the Cosori, which makes me incredibly happy.

The crisper plates can go in the dishwasher, while the main drawer is better suited to hand washing simply because of its size. In practice, grease and residue lift away easily with warm soapy water, and the ceramic coating holds up beautifully over repeated use.

How does the Cosori Dual Blaze TwinFry compare?

The most natural comparison here is with the Ninja FlexDrawer, and the two are closely matched in both concept and performance.

In terms of dimensions, the Cosori measures 33.8 x 51.8 x 31.3 cm, while the Ninja comes in slightly more compact at 32.7 x 49.6 x 31.6 cm. On a countertop, the difference is subtle and I didn't notice it. However, I did spot some people who planned to swap their Ninja FlexDrawer out for the Cosori and they found the handle's extra space meant it couldn't squeeze in some very specific slots on the counter. So, if you have a hunch that's you, it's worth doing some measuring.

Design-wise, the Ninja feels more utilitarian, with a slightly bulkier, more angular build and a dial that can be fiddly to keep clean. Cosori, by contrast, leans into a sleeker interface and smoother surfaces that are easier to maintain.

The Ninja does include a Max Crisp function, which essentially pushes the fan speed and temperature higher for faster results. In practice, the Cosori’s dual heating elements compensate well, delivering evenly cooked food without requiring that extra boost setting. Yes, it is a little slower to cook food (and actually nearly 10 minutes slower on chips), but I think that the cooking quality warrants the extra time. Overall, he performance gap is minimal, and in some cases, the Cosori’s consistency actually edges ahead.

Should you buy the Cosori Dual Blaze TwinFry?

If you’re looking for a versatile, high-capacity air fryer that simplifies cooking, the Cosori Dual Blaze TwinFry Air Fryer is an excellent choice.

It’s particularly well suited to larger households or anyone who wants to cook multiple elements of a meal at once without compromising on texture or timing. The dual-zone flexibility, paired with the "Grandzone" option, means you can move effortlessly between everyday cooking and bigger, more ambitious dishes.

From a technical perspective, the dual heating system, precise temperature control, and extended cooking functions give it a clear advantage over many mid-range models. It also helps eliminate common air fryer mistakes, like uneven cooking or the need to constantly check and shake food. It's seriously impressive.
