ASDA is selling an air fryer big enough to fit a roast dinner in for £99 – and it could help slash your energy bills.

The supermarket‘s Scoville Digital Air Fryer has two cooking shelves and a rotating rotisserie bar you can fit a whole chicken on.

It has an 11 litre capacity and there’s eight cooking settings depending on what you’re cooking.

Air fryers have become a popular kitchen gadget as households look to find cheaper ways to cook their food.

Cooking time tends to be quicker than using an oven or frying pan and they cost less to run.

Asda’s may be more expensive than other models because it’s a lot bigger, but if you’re planning on using it for roast dinners, it could be a good investment.

It’s also £100 cheaper than the popular Ninja Foodi Dual Zone Air Fryer.

It’s currently out of stock online, but shoppers have spotted the gadget in stores according to posts on the Extreme Couponing and Bargains UK Facebook group.

You can use Asda’s store locator tool to find your nearest store.

Before you commit to a purchase, you should have a shop around to make sure you’re getting the best deal.

We couldn’t find a cheaper air fryer similar to this.

How much does it cost to use?

The answer won’t be the same for everyone, as what you pay for electricity will depend on your tariff and also how large and efficient your appliance is.

As with any appliance, a newer model is likely to be more efficient, and be cheaper to run than an older version.

The power of an air fryer is measured in watts, and this determines how much energy it uses – and the cost of using it.

But the more powerful the appliance, the quicker it will cook your food too.

The equation you need to work out the cost of using any appliance is: Cost = power (kilowatt) x cost of one kWh (pence) x the length of time (just the one off meal, or over a week or month.)

Some of the cheaper models will typically use around 900 watts.

And you’re probably going to need to use it for around 20 minutes to cook your dinner to perfection.

The experts at Uswitch told The Sun that if you used a 900-watt air fryer for 20 minutes, it would cost about 10p per meal.

A larger 1,500-watt air fryer used for around the same amount of time, would cost almost 17p per meal. 

So if you used the smaller fryer five days a week for a year, that would cost a total of £26.52.

The energy supplier Utilita said that a 4.4l air fryer costs £52 a year to run.
