Air Fryer vs Convection Oven what's the difference and which one is right for your kitchen counter top?

If you are looking for a healthier way to cook your food that doesn't involve lots of fatty oil then you have probably looked at either an air fryer or a convection oven.

Both will give you the ability to ​cook foods with a small coating of oil and thus help reduce the amount of fat that you use.

However, they do differ in what they can make and how good the results will be.​

But Which should you buy ?

If you are in a rush and don't have time to read the rest of the article then in our opinion a convection oven is the one to get.

Our Top Pick

  Breville Smart Oven

  • 1800 Watt ,5 heating elements, one fan
  • Optional toasting facility
  • 9 different presets for various dishes
  • Built in backlit LCD display

Air fryers can be extremely finicky when it comes to getting the temperature, cooking times and the amount of oil you may have to toss your food in first(if it needs it).

For some dishes a lot of experimentation is required to get the perfect ​blend between cooked thoroughly and too crispy.

You are also fairly limited in just how much food you can actually cook in an air fryer. In a lot of models the basket is considerably smaller than you first might realize.​

A convection oven is also a lot more versatile. It gives the ability to cook considerably more varied types of dishes than you can in an air fryer and will give you more consistent results time and time again​.​

What is an Air Fryer​ ?

Despite what the name suggests an air fryer is not actually a fryer in the traditional sense. There is no oil well that contains heated oil. Instead it forces hot air down through the food basket from above. 

Because you are not "frying" in the traditional sense air fryer champions will always be quick to point out that food that is cooked in an air fryer will be considerably healthier than in a traditional fryer.

With a normal oil based fryer some of the oil will always be absorbed by the food as it is being cooked. This means that your food will have a much larger fat content than normal.

With an air fryer you will have the added health bonus of reduced fat, however that bonus will be at the expense of taste i.e it will never be so good as deep fried.

How does an air fryer work ?

As mentioned above an air fryer works by forcing hot air down from above and onto the food that is usually contained in a basket.

It has a powerful fan mounted above a heating element. The air is then force downwards over the heating element and then onto the food below.

The food is usually in a basket similar to what you might find in a traditional fryer. The basket is always located at the bottom of the air fryer.

Despite the name an air fryer is not going to give you the traditional results that you would expect from a normal hot oil deep fryer.​

You will not be able to replicate either the flavor profile or the texture that you will find in a traditional fryer. Achieving a crispy, golden brown outside to your favorite fries or fried chicken is still best done in a normal fryer.​

​However as you can see in the above video you can still get some pretty decent results from one provided you know what you are doing.

An air fryer is works on the exact same principle as a convection oven, a fan is used to circulate the hot air around the food to give an even distribution on heat.

The real difference between an air fryer and a convection oven is the the air fryer has a basket that is located at the bottom of the fryer and hot air is forced down from above. Whereas a convection oven is more like a traditional oven plus a fan.

What is a convection oven ?​

A convection oven works the same as a standard oven with the addition of a fan to help circulate the air around. ​

How does a convection oven work ?​

With a convection oven the heating elements can be placed on the top, bottom and side walls of the cooker and a fan is used to circulate the air normally from the back wall. 

A Convection oven may or may not also contain a top grill or a toasting element that allows you to grill food.​

​Convection ovens have one major advantage in terms of the types of food that they can cook. Pizza and toast.

Why ?

Because of their shape. An fryer is usually round and has a very limited size to the basket. However, a convection oven is the usual rectangular shape that has the ability to take fairly large pizza.
