Cosori Air Fryer Review UK 2025: Smart Features at a Sensible Price?

Cosori has carved out a solid reputation in the UK air fryer market by offering models that do more than competitors at comparable price points. The two most talked-about options right now are the Cosori Pro Gen 2 and the Cosori Dual Blaze — one pitched at app-connected convenience, the other at faster, more even cooking through dual heating elements. This review covers both, based on what they actually deliver at the chip-and-chicken end of things.

Cosori Pro Gen 2: The Smart One

Build and Capacity

The Pro Gen 2 is a 5.5-litre square-basket fryer — that square footprint makes better use of interior space than round alternatives, and you can comfortably fit a spatchcocked chicken or a generous load of chips in a single go. Build quality feels sturdy without being heavy. The non-stick basket releases cleanly and is dishwasher safe, which matters more than it sounds after the fifth consecutive use.

At around 1,700W, it sits in the mid-range for power. It won't heat up quite as fast as premium 2,000W models, but preheat time is still around three minutes in practice.

App and Smart Features

The headline feature is Wi-Fi connectivity via Cosori's VeSync app, which works on iOS and Android and integrates with both Amazon Alexa and Google Assistant. The app gives access to over 100 recipes with step-by-step guided cooking, including automatic temperature and time settings that push directly to the fryer. For anyone who uses their phone constantly in the kitchen, this is genuinely useful — you're not squinting at a manual to work out whether halloumi needs 180°C or 200°C.

The on-device experience offers 11 presets covering the usual suspects: chips, chicken, steak, seafood, bacon, and so on. The touchscreen is responsive and clearly labelled. If you don't want to engage with the app at all, you won't feel like you're missing much for everyday cooking — but the app earns its keep when you're branching out.

Real-World Cooking: Chips and Chicken

Frozen chips at 200°C for 18 minutes came out evenly golden with a decent crunch, though a shake at the midpoint is still advisable for the fullest crispness. Homemade chunky chips needed closer to 22 minutes but were excellent — properly crispy outside, fluffy inside, with no oily residue.

Chicken thighs at 190°C for 22 minutes hit 75°C+ internally and came out with properly crisped skin. Breast fillets were juicier than oven equivalents cooked the same day, largely because the circulating air locks moisture in more efficiently than radiant oven heat.

One limitation: larger whole chickens above about 1.5kg will be a squeeze. You can do it, but you'll need to monitor carefully and it's tight.

Cosori Dual Blaze: The Performance Upgrade

What's Different

The Dual Blaze departs from the standard single-element design by using heating elements at both the top and bottom of the unit. The result is more even heat distribution without requiring constant basket-shaking. Cosori calls this TurboBlaze technology — the marketing language is a bit breathless, but the underlying engineering difference is real.

Capacity steps up to 6.4 litres, and power to 1,800W. Preheat times edge ahead of the Pro Gen 2 noticeably.

The Dual Blaze is not a Wi-Fi model in its standard UK configuration, which makes it the right choice if app connectivity feels like unnecessary complexity. The interface is straightforward: touchscreen controls, a clear display, and enough presets to cover everyday cooking without confusion.

Cooking Performance

The practical benefit of the dual-element design shows up most clearly with thicker cuts of meat and denser vegetables. Bone-in chicken pieces cooked more evenly compared to the Pro Gen 2 — less of the "overdone outside, undercooked near the bone" problem that plagues some single-element fryers. Salmon fillets were notably good: crisp exterior, moist centre, cooked in under 12 minutes.

Chips performed well here too, and the reduced need for mid-cook shaking is a small but genuine quality-of-life improvement. Reheating pizza, often a messy test for any fryer, produced a properly crispy base rather than the soggy result you get reheating in a microwave.

How They Compare

| Feature | Pro Gen 2 | Dual Blaze | |---|---|---| | Capacity | 5.5L | 6.4L | | Power | 1,700W | 1,800W | | Wi-Fi / App | Yes (VeSync) | No | | Heating Elements | Single (top) | Dual (top + bottom) | | UK Price (approx.) | £80–£100 | £100–£130 |

The price gap is modest. If you cook for two to three people regularly and like the idea of guided recipes and voice control, the Pro Gen 2 is the more logical choice. If you're cooking for four-plus and want consistently better results on larger or thicker foods, the Dual Blaze justifies the premium.

Honest Drawbacks

Both models share a common weakness: the baskets aren't huge. A full Sunday roast with accompaniments will still need your oven. The non-stick coating, while good, will degrade if you use metal utensils or abrasive cleaning — silicone tools and hand-washing occasionally is the sensible approach.

The VeSync app, while capable, does occasionally push notifications more aggressively than needed. Worth adjusting the settings after initial setup.

Verdict

Cosori has built two genuinely capable fryers that compete honestly against Ninja and Philips at similar price points. The Pro Gen 2 wins on smart features and value; the Dual Blaze wins on cooking performance and capacity. Neither will disappoint if you go in with realistic expectations — these are excellent everyday kitchen tools, not magic boxes.

For most UK households buying in 2025, the Pro Gen 2 is the easier recommendation on price-to-performance grounds. Step up to the Dual Blaze if you regularly cook larger portions or find yourself frustrated by uneven results from a single-element fryer.
