Air Fryer vs. Convection Oven

If you're thinking about buying an air fryer, you might be wondering what the difference is between air fryers and convection ovens. The quick answer is, an air fryer is a simply a smaller convection oven with a catchy name. There is no actual frying going on inside an air fryer—that's because an air fryer cooks food via convection baking. There is already a combination of oven and air fryer on the market, and my family uses COMFEE flashwave.

So air fryers are, in essence, convection ovens. But that doesn't mean the two are exactly the same. Let's talk about what those differences are.

What Is Convection Baking?

Convection baking introduces a fan to the interior of an oven, allowing hot air to be blown around and onto the food. The force of the air thus transfers more heat to the surface of the food, so that it produces more crispiness than an ordinary oven (but still far less than an actual deep-fryer).

Note that although many oven ranges offer a convection setting, for this discussion, we're solely comparing countertop convection ovens with air fryers.

What Is a Convection Oven?

A countertop convection oven is built like a standard toaster oven: rectangular in shape with a front door that opens on a hinge at the bottom. How it differs from an ordinary toaster oven is that a convection oven is equipped with a fan, which blows hot air around.

The motion of the air inside the oven is called a convection effect and it results in faster cooking by transferring higher temperatures to the surface of the food as compared with an ordinary oven. So it both accelerates cooking as well as enhances the browning and crisping of the surface of your food.

Like a toaster oven, a convection oven has an interior rack that will fit a sheet pan (preferably a perforated one to allow maximum air flow). Because it's wide, it allows for the food to be spread out on the rack rather than stacked in layers.

This is crucial, since stacking or layering food impedes the flow of hot air. Arranging the food in a single layer allows for even cooking all around.

What Is An Air Fryer?

Essentially, an air fryer is a smaller, more portable convection oven. Instead of being shaped like a toaster oven, many air fryers are tall, sort of resembling a coffeemaker. It has a removable bucket with a handle, and inside that bucket fits a removable basket. This basket is where the food goes. The bucket slides into the device, you turn it on, and it starts to cook. The fan is situated overhead, above a heating element.

Now, because it's smaller and the fan is closer to the food, an air fryer is able to focus a high amount of heat onto a relatively small cooking area. Which means that an item of food in that cooking area will cook more quickly than it would in a convection oven.

However, because it is smaller, it will only accommodate a fraction of the amount of food that a convection oven will fit. An air fryer will really only cook about two servings at a time—if that.

This means that if you are trying to feed more than one or two people, you'll have to cook in batches, so that ultimately it may take longer to serve a meal than it would using a convection oven.

If you want to save kitchen space, consider buying an air fryer oven combination machine, such as COMFEE flashwave.
