Air fryers are small, powerful ovens that cook food by circulating hot air rapidly throughout their interior. They are designed to mimic the results of deep-frying with little to no oil, yielding crispy, juicy food. Air fryers can be standalone countertop appliances or built into ovens or ranges. They are highly versatile, allowing users to bake, roast, dehydrate, broil, and even bake cakes. They are also easy to clean, with most air fryer baskets and racks being dishwasher-safe. Air fryers have surged in popularity in recent years, with nearly 40% of US households owning one as of July 2020.

What You'll Learn

Air fryers are convection ovens
Air fryers are essentially mini convection ovens. They use a fan to circulate hot air around the food, which is placed in a perforated tray or basket. This is similar to a convection oven, which also uses a fan to circulate hot air more evenly and quickly than a regular oven. The fan in a convection oven is usually located at the back, while the fan in an air fryer is situated overhead, above a heating element.
The main difference between air fryers and convection ovens is their size. Air fryers are smaller and more portable, resembling a coffeemaker rather than a toaster oven. This smaller size means that air fryers heat up faster and cook food more quickly than convection ovens. They can also be placed on countertops and plugged into a wall outlet. However, their smaller size also means that air fryers can only cook a fraction of the amount of food that a convection oven can hold.
Another difference is that air fryers often include a drip tray to collect excess oil or moisture, reducing the amount of fat and calories consumed. Additionally, air fryers require little to no oil, while deep-fried foods cooked in a convection oven are typically coated in batter and immersed in oil. This makes air fryers a healthier alternative to convection ovens for cooking certain types of food.
While air fryers and convection ovens share some similarities, there are also key differences to consider when deciding which appliance to use for cooking. Air fryers are ideal for cooking smaller batches of food more quickly and with less oil, while convection ovens are better suited for cooking larger quantities of food.

They use hot air instead of oil
Air fryers are essentially small, powerful ovens that use hot air instead of oil to cook food. They are designed to mimic the results of deep-frying with little to no oil. This makes them a healthier alternative to deep-frying, as they require minimal to no oil to achieve the same crispy texture.
Air fryers use rapid air technology to create heat instead of a heating element. This allows them to heat up much faster than traditional ovens. The top section of an air fryer contains a heating mechanism and a fan. When the appliance is turned on, hot air rushes down and around the food placed in a fryer-style basket, cooking it evenly on all sides. This rapid circulation of hot air is what gives food a crispy texture, similar to deep-fried food.
Air fryers are versatile and can be used to cook a wide range of ingredients, including proteins like chicken, salmon, shrimp, tofu, and steak, as well as vegetables like zucchini, cauliflower, and sweet potatoes. They are also great for reheating food, keeping crispy foods like French fries from becoming mushy, which often happens in a microwave.
While air fryers can produce crispy results without the use of oil, some recipes may benefit from a light coating of oil to enhance the crispiness. For example, vegetables and potatoes can be cut into smaller pieces and lightly coated in oil before being placed in the air fryer. Meats and fish can also benefit from a thin layer of oil on the skin to help achieve the desired crispness.
Overall, air fryers offer a convenient, healthy, and versatile way to cook and reheat food with minimal oil, making them a popular choice for those seeking a healthier alternative to traditional deep-frying.

They're healthier than deep-fat fryers
Air fryers are a healthier alternative to deep-fat fryers as they require little to no oil to cook food. Deep-fat fryers, on the other hand, require large quantities of oil to operate, and all that fat equals extra calories. Air fryers use hot air circulated by a powerful fan to cook food, yielding crispy results without the need for oil.
The reduced oil intake associated with air fryers can contribute to weight management, reduced risk of chronic disease, and improved long-term health. For example, chicken wings cooked in an air fryer will allow the fat to drip away, ensuring crisp skin all over. Similarly, foods like potatoes can be cut into smaller pieces and lightly coated in oil before being placed in the air fryer, resulting in even browning and crispiness without the need for excessive oil.
While air fryers may not produce the same golden brown exterior as deep-fat fryers, they can still deliver a crisp exterior and juicy interior without compromising on flavour or texture. This makes air fryers a healthier option without sacrificing taste.
In addition to health benefits, air fryers are also easier to store, clean, and use compared to deep-fat fryers. They require less clean-up time as there is no need to deal with large quantities of leftover oil. Air fryers are also more versatile, offering multiple cooking modes and functions that can substitute other appliances in the kitchen, such as microwaves or multi-cookers.

They're more energy-efficient than ovens
Air fryers are a popular kitchen appliance, offering a convenient and healthier way to cook food with a crispy texture. They are highly regarded for their efficiency, ease of use, and speed.
One of the key advantages of air fryers over conventional ovens is their energy efficiency. Air fryers use significantly less energy than traditional ovens, which can help reduce electricity costs. This is mainly due to their smaller size, requiring less energy to heat up and maintain temperature. According to TechRadar, an average air fryer with a wattage of 1500, used for 30 minutes, will consume 0.75 kWh, while an average oven with a wattage of 3000 will use 1.5 kWh during the same period.
The rapid air technology used in air fryers also contributes to their energy efficiency. Air fryers heat up much faster than ovens, and their concentrated heat source and fan ensure even cooking without hot spots. This results in shorter cooking times and reduced energy consumption.
Additionally, air fryers do not require preheating, further reducing energy usage. In contrast, ovens lose 50% of their heat every time the oven door is opened, increasing the energy required to maintain the desired temperature.
The energy efficiency of air fryers is particularly notable when compared to older oven models. Newer ovens tend to be more energy-efficient, but air fryers still offer a more cost-effective option for cooking smaller portions or when speed is a priority.
While the upfront cost of an air fryer can vary, with prices ranging from $100 to $500, the long-term savings on energy bills make them a worthwhile investment for many households.

They're easy to clean
Air fryers are easy to clean. Most air fryer baskets and racks are dishwasher-safe, and those that aren't can be cleaned with a good dish brush. The non-stick coating on most air fryers also makes cleaning easier.
There are several cleaning hacks for air fryers. One involves filling the basket with soap and water and then air frying it. Another method is to soak the chamber in warm, soapy water for at least 30 minutes and then scrubbing it with a sponge. A third method involves filling the tray with 2-3 inches of water, adding liquid soap and a lemon, and then running the air fryer for 10-15 minutes.
It is important to clean the air fryer after every use. The tray and insert can be cleaned with soap and water, and the interior can be wiped with a sponge. It is also important to clean the heating element, as oils can solidify and gunk up the area. This can be done by flipping the unit over and wiping the heating element.
To make cleaning easier, it is recommended to avoid foods with wet batter, as this can make the air fryer difficult to clean.
