Cosori Pro 4.7L air fryer summary

Whether you're looking for a countertop statement or a lightweight air fryer for storing in the cupboard, this is an excellent choice. The gadget is controlled using a tempered glass panel on its roof. It offers seven preset functions (chicken, fries, frozen, steak, seafood and veggies) with time and temperature both manually adaptable, and is the first model we’ve ever tested with a dedicated bacon function – an innovative addition, if a little niche.


We love the contemporary design with a sleek matte finish and rounded edges. The pull-out drawer also features a lock and it won’t turn on unless the tray is fully loaded. That's a big tick in terms of safety.

How easy is it to build?

Like all the other Cosori fryers we've tested, the box is packed with information about the fryer's capabilities. The fryer itself is small and incredibly lightweight. It's also quite stout, so could be pushed back under low cupboards for storage, then brought forwards for use. The heat release is at the back and the manual instructs that it must be placed away from other objects (13cm by 13cm).

An envelope containing the instructions, a 30-recipe booklet and two-year warranty card is included in the box. The materials have a good-quality feel, matte grey with a well-fitting tray that locks with a button requiring release before use.

The instruction manual is clear and easy to follow. It outlines the elements that come with it (although the machine is preassembled) and guides you on where the crisper plate slots into the drawer. The crisper tray has four silicone corners to protect the non-stick coating and slots in nicely to allow fat and juices to run off – useful when cooking chicken, for example.

How easy is it to use?

The preheat button means you can get the cooker up to temperature before adding ingredients. The time auto-adjusts depending on the temperature you preheat it at. We selected 190C, which warmed for four minutes. After that, it’s just a case of setting your temperature and cooking time (or follow one of the presets).

When using the air fryer, we reduced traditional oven temperatures by 10C to account for the cooker's efficiency and heat, which turned out to be ferocious. When using the bacon function, we were able to fit three rashers of traditional bacon in at a time.

The machine beeps to remind you to shake its contents if you’re cooking things like chips. One thing that impressed was the air fryer's extremely low noise levels during cooking – something the brand is very proud of.

Cooking results

We popped a small whole chicken into the Cosori's tray with a lick of oil across the skin to encourage crisping and set the cooker to 55 minutes (based on the included cooking guide) at 190C. It was ferociously hot. The top of the chicken was dark, so we would suggest five to 10 minutes less. The bacon function left us with cooked rashers that weren't crispy. Leaving them for five minutes longer would have helped.

The efficiency worked well for the chips. The machine beeps to remind you to shake its contents, then auto-starts when the drawer is replaced. The chips were very dark but had a good seal and were soft on the inside. We would suggest removing five minutes from this preset, too.

How sustainable is this air fryer?

Inside the box, the packaging is predominantly plastic. Disappointing, especially because there are so many eco-friendly alternatives that the brand could have used. Its two-year warranty sets a good precedent for repairing if you register the gadget on purchase, but it's important to do so. Really these models should last you longer than two years, with the right care.


This is a practical little machine for a small to medium household that is setting a new standard for air fryers. The 4.7L capacity will give you two mains or four side dishes from its deceptively small drawer. The removable parts are dishwasher safe for easy cleaning and, thanks to its lightweight body, it's no faff to move it from countertop to cupboard if needed.
