What are the benefits of getting an air-fryer?

Air-fryers are convenient

One of the primary perks of owning an air-fryer is the convenience they offer. Like any kitchen gadget, you want something that’s going to make life simpler, and there’s no doubt that frying and baking conventionally can be messy and even dangerous.

Think of air-fryers as mini ovens that can tackle almost anything you’d put in a conventional oven or deep-fat fryer. And because they're typically more compact than traditional ovens, they also heat up and circulate hot air more efficiently around food – resulting in meals cooked faster.

"When using an air-fryer, I tend to opt for simpler recipes that take longer and use more energy when cooked differently – for example, jacket potatoes," says Samuel Goldsmith, food copy editor for BBC Good Food.

"Energy savings will depend on what tariff you are on and also what you’re cooking, but most things cook more quickly and air-fryers tend to be more energy-efficient than convection ovens."

Air-fryers are versatile

Most models are able to perform multiple functions, and it’s impressive to see how much is packed into their compact countertop footprint. You can bake, roast, dehydrate and grill in almost all of the models we’ve tested, and some also come with presets for specific ingredients like chicken, pizza, fish and steak.

When shopping for air-fryers, we recommend looking closely at the settings, features and capacity of each model to ensure it meets your needs. For a smaller household of one or two people, a single-drawer, basket-style air-fryer might be ideal, while dual-drawer options may be better suited to larger households.

Air-fryers require less oil

It's no secret that air-fryers use less oil than deep-fat fryers, which means they can be a healthier way to cook 'fried' favourites like chips, chicken thighs and doughnuts.

Other popular air-fryer recipes include air-fryer crispy chilli beef, air-fryer buffalo cauliflower wings and air-fryer pasta chips.

That said, air-fried foods are still classed as fried food, so you should try to enjoy them as part of a balanced diet. Read more about the health credentials of air-fryers in our guide – is air-frying healthy?

Air-fryers can be energy efficient

Not only does an air-fryer save you precious counter space, they’re often cheaper to run than ovens, particularly if you’re only heating up food for one or two people.

They do vary in their energy efficiency, but you can work out how much energy your appliance is using, to get a better idea of how much money you can potentially save. To calculate this, multiply the wattage of your air-fryer by the number of hours it's used each day, and divide the total by 1,000. This will give you its daily kilowatt-hour (kWh).

The cost-per-kilowatt-hour will vary depending on where you live and what your energy tariff is, but if you have a smart metre installed, you should be able to see the cost-per-use during cooking will be visible without doing any calculations.

The verdict: are air-fryers worth it?

Air-fryers have become a game-changing gadget for many households, and when used appropriately, they can transform how we prepare and cook meals at home. The key is to do your research before you buy – think about your individual requirements, like functions, size, speed, and price, and perhaps mostly importantly, what you like to cook.

Capacity is also a big factor. For instance, if you're switching your oven on to cook one or two smaller items, like chips or chicken wings, you should find an air-fryer is more efficient in comparison. But, for larger portions that exceed the capacity of your air-fryer, you might want to think about using a different appliance instead.

There are certain ingredients that are less suited to air-frying, too – read our guide on what not to cook in an air-fryer, plus food editor Ailsa Burt's top air-frying tips.
