What is an Air Fryer?

Also known as an air fryer convection oven, an air fryer can be a countertop appliance, or a feature built into an oven or range, that allows you to cook crispy, golden-fried food without using a pot or pan full of oil. 

How Does an Air Fryer Work?

An air fryer works by circulating hot air rapidly throughout its interior. Similar to a convection oven, there’s a fan that circulates hot air around food in a perforated tray or basket. Because all the surface areas of the food are exposed to the hot air, the food cooks to become crispy on all sides without having to be submerged in hot oil.

What Are the Different Types of Air Fryers?

Air fryers differ based on size and cooking functionality. Some air fryers are standalone countertop appliances, others are built into ovens or ranges, as well as some countertop ovens.


Standalone air fryers are usually oval-shaped, similar to that of an egg and contain a basket in which you place the food. They are usually placed on a countertop and plug into a wall outlet.

What are the Benefits of Air Frying?

The primary benefit of air frying is reduced use of oil, which can help to cook meals that are lower in fat and calories vs. traditional deep frying. If you have a countertop air fryer or an appliance with air fry capabilities, here are some benefits you can enjoy: 

  • Crispy results - An air fryer provides consistently crispy results without having to coat ingredients in batter or immerse in oil. 

  • Speed - Select KitchenAid® countertop ovens with air fry come with nine cooking settings and fast preheat features to help you create perfectly crisp dishes with ease.

Is Air Fried Food Healthy?

Because air frying relies on rapidly circulating hot air to crisp up and brown food, there’s no need to immerse foods in hot oil to create the desired crispy texture. An air fryer only requires a few tablespoons of oil, or none at all, to crisp up a range of ingredients, so it can be considered a healthier cooking method than frying in oil.

What Can You Cook in an Air Fryer?

From classic air fryer foods like chicken wings and potatoes to fresh recipes like zucchini fries, an air fryer can crisp up a wide range of ingredients. The best foods to air fry include proteins like chicken, salmon, shrimp, tofu and even steak, along with firm vegetables like zucchini, cauliflower and sweet potatoes.

Typically, solid foods with a lower water content are best to air fry; for example, cruciferous vegetables like broccoli and brussel sprouts are better to air fry than lettuce or cucumbers. 

Cut vegetables and potatoes into smaller pieces, like medallions or cubes, to make it easier for the hot air to reach their complete surface area and result in even browning and crispiness. Be sure to lightly coat in oil before adding to the air fryer.

Make sure that the skin of meat or fish is dry and then add a thin layer of oil to help the skin crisp up. You can also use panko, shredded cheese or bread crumbs (rather than a wet batter) to encourage the right level of crispiness.

What Cannot Be Cooked in an Air Fryer?

Avoid foods dipped in wet batter. While deep frying foods often requires dipping into a wet batter, this process is not compatible with air fryers and could make it more difficult to clean your air fryer. You should also avoid putting delicate, leafy greens like spinach into the air fryer.

For crispy and delicious chicken wings, pat the wings dry before adding seasoning to them–a dry rub of salt, pepper and some garlic powder will suffice to get a nice and golden crisp. Cook in your air fryer and flip them once halfway through, unless you have a model with a no-flip basket. To add sauce, once your wings are done cooking, toss them in a coat of sauce and add them back to the air fryer for another few minutes.
