Cosori TurboBlaze 6L Air Fryer

Summary

Is it worth paying extra for a DC motor in a 6-litre air fryer, or is it just marketing hot air? After three weeks of cooking every day with the Cosori TurboBlaze 6L for two and three people, our answer is that you do notice it, although not in everything the box promises.

What impressed us most is the even cooking without shaking the basket. The boosted fan (1,725 W of rated power) moves the air hard enough to brown the centre and the edges equally, and with chips, wings and vegetables that means fewer trips to the drawer and slightly shorter cooking times than other air fryers in a similar range that we’ve tested.

It suits two- or three-person households who want a compact machine (36.6 cm long, 28.6 cm wide and 30 cm high) with an unusual temperature range: 30 to 230 °C, with a timer from 1 minute to 24 hours. That very low minimum is what lets you dehydrate fruit or prove dough, something most air fryers this size simply don’t offer.

Beyond frying, the feature we got the most out of is the proving programme combined with the long timer, because you can leave bread dough rising at a controlled temperature while you get on with other things. The keep-warm mode also stops dinner going cold if someone’s running late.

The catch is capacity. The 6 litres take four fillets without overlapping or chips for three people, but they fall short for a whole chicken or a hungry family of four. If you cook in big batches, there are larger models that will save you a second round.

Analysis and verdict

Cooking results – Score: 9.1/10

The heart of this air fryer is its boosted fan, which Cosori says increases airflow by 28% over its previous models. In our experience that figure translates into something concrete: there’s no need to shake the basket halfway for the chips at the edge and in the centre to come out equally golden, which you do have to do with similar air fryers with a conventional motor.

The fan speed control is the least advertised feature and the one we found most useful. At top speed, wings come out with crisp skin across the whole load; at a low speed, with broccoli or any light vegetable, you stop the tips burning, which is where more aggressive machines fall down. Compared with a 5–6 litre air fryer without fan control, you have room to tailor the result to each food.

Be wary of the marketing percentages, though. The much-quoted 46% faster cooking is measured against ‘traditional air fryers’ without saying which, and the 95% less oil is compared with deep frying, not with other air fryers. What we can say is that cooking times were shorter than with the models in this range we’ve had in our kitchen.

Capacity – Score: 8.0/10

The stated 6 litres are designed for 2–3 people, and in our case that figure is honest: four medium chicken fillets fit without touching and with air around them, which is exactly what an air fryer needs for the airflow to work. Cosori talks about 1 kg of chips or 400 g of salmon in one go, and with chips we worked comfortably.

Compared with an 8–9 litre or dual-drawer air fryer, you lose the option of large pieces and cooking two things at once, but you gain a machine that fits on a normal worktop and weighs 6 kg, manageable if you need to put it away in a cupboard. If there are four or more of you, or you often roast whole chickens, this format will be too small and there’s no trick to get round it.

Cleaning – Score: 8.5/10

The basket is dishwasher safe and the non-stick coating releases grease easily, so everyday cleaning is quick. The body, a metal casing with a glass touch panel, can only be wiped with a cloth, which is normal in this category but worth knowing before you buy.

Where it falls down a little is the divider: its corners trap oil and don’t always come clean with the first pass of the sponge. Compared with the round-basket air fryers we’ve tested, this wider format has more nooks, and although the rim of the basket doesn’t collect baked-on grease as it does on other models, the divider needs an extra going-over after cooking something greasy.

Noise, control panel and handling

Cosori quotes a noise level of 27 dB, and in our kitchen it came across as a restrained appliance, well below the roar we associate with powerful air fryers. If you eat late or your kitchen is open to the living room, this matters more than it might seem on a spec sheet.

The glass touch panel responds well even with slightly damp fingers, although with constant use it shows fingerprints and needs a regular wipe if you want it to look smart. The handle has a safety catch that stops the basket dropping out when you lift the drawer, which you’ll appreciate when you pull it out full of sizzling wings.

We noticed that at 230 °C the upper rear part of the metal casing, next to the air outlet, gets noticeably warm to the touch. It doesn’t burn or become uncomfortable, but it’s best not to push it right up against a wall or a delicate cupboard. The nine programmes (Air Fry, Roast, Bake, Dehydrate, Grill, Frozen, Reheat, Proof and Preheat) come with a printed booklet of 30 recipes and another 117 in Cosori’s free app.

Pros

• Even cooking without shaking: the boosted airflow browns the centre and edges equally, so you don’t have to open the drawer halfway through chips or wings.
• 30 to 230 °C range with a timer of up to 24 h: you can dehydrate fruit or leave dough proving, which air fryers this size rarely allow.
• Fan speed control: turn the airflow down for light vegetables and up for crisp skin, so you avoid burnt tips without giving up crunch.
• Low noise (27 dB stated): you can use it late at night or in an open-plan kitchen without the fan drowning out the conversation.

Cons

• Capacity only just right for 2–3 people: a standard whole chicken won’t fit, and for four people you’ll need to cook in two batches.
• The divider traps oil in the corners and the body can only be wiped with a cloth, so after greasy food, cleaning isn’t as ‘one wipe and done’ as the basket.

Our test

Test 1: Cooking results – 500 g of chips without preheating

We tested the TurboBlaze in Spain, and it’s the same 6-litre model sold on Amazon.co.uk (reference CAF-DC601-KUK). We put 500 g of 1 cm-cut chips in a single batch, without preheating, on the chips programme at its default temperature, and halfway through we opened the drawer to compare the chips in the centre with those at the edge. We repeated the test with 20 wings and a tray of broccoli florets, alongside a similar air fryer that also moves the air but without a boosted fan.

The chips came out evenly golden without being touched, and the programme finished sooner than we’re used to with other models. One detail you won’t guess from the spec sheet: for the first few minutes the airflow pushes the thinner chips against the grill and you hear a metallic rattle, which stops once the potato loses moisture. It’s not a fault, but it’s surprising the first time. If you hate keeping an eye on the drawer, this result justifies the highest score in the review.

Test 2: Capacity – four fillets and the reference 20 wings

We loaded the basket with four medium chicken fillets laid out without overlapping and, in another session, with the 20 wings Cosori gives as the maximum load. We judged the free space by eye and compared it with another 5–6 litre air fryer in a similar range that we’d already tested, to see whether the stated volume translates into usable surface.

The fillets fitted with room to spare, but the 20 wings filled the basket and had to be spread over two partial layers, without quite stacking up, and a standard whole chicken doesn’t fit because of the height of the chamber. On the plus side, the base is flatter and wider than other baskets of the same capacity, so you make better use of every centimetre exposed to the air. If you cook for two or three, it’s more than enough; if you want big roasts, this isn’t your machine.

Test 3: Cleaning – washing up after the wings, by hand and in the dishwasher

After the batch of wings, with plenty of loose fat, we let the unit cool completely and washed the basket and divider with a non-abrasive sponge, hot water and washing-up liquid, without soaking, to see what the non-stick released first time. In another session we put the basket straight into a normal dishwasher cycle.

The grease on the basket walls came off in one pass, while the divider needed a second go right in the corners where oil had collected. It came out of the dishwasher with no residue or smell, and after several washes with a sponge the coating shows no scratches and hasn’t lost its sheen. What we can’t say is how the non-stick will hold up after a year of daily dishwasher use; in three weeks it showed no signs of wear.
