Experts caution against using air fryers instead of ovens.

In recent years, technological innovations have steadily transformed the way people cook at home.

One appliance in particular has quickly become a favorite in kitchens around the world: the Air fryer.

Praised for its convenience and ability to produce crispy foods with little oil, the air fryer has become a popular alternative to traditional ovens and deep fryers.

Many households now rely on air fryers for everyday meals, and some people have even replaced other appliances—such as slow cookers or small countertop ovens—with this compact device.

The reason for its popularity is simple: it promises the taste and texture of fried food while using far less oil, making it a more health-conscious cooking option.

Air fryers work by rapidly circulating very hot air around the food using a powerful fan. This process creates a crispy exterior similar to frying, but without submerging food in oil.

Because of this method, air fryers can cook foods like fries, chicken wings, vegetables, and frozen snacks quickly and efficiently.

However, despite their growing popularity, culinary experts warn that not every food is suitable for this appliance.

While air fryers are extremely versatile, there are certain ingredients and dishes that simply don’t perform well—or may even pose a safety risk—when cooked this way.

For example, vegetables such as broccoli can sometimes turn out disappointing in an air fryer.

While it may still cook, the results often lack the rich flavor and caramelization that traditional roasting in an oven can provide.

The intense airflow can also cause smaller pieces to dry out or become overly crisp before they develop proper flavor.

But broccoli isn’t the biggest concern. Some foods can actually cause problems inside the appliance.

One surprising example is popcorn. While it might seem harmless to toss a few kernels into the air fryer basket, experts strongly advise against it.

Popcorn kernels can become lodged in the heating element or internal vents of the appliance. If this happens, the trapped kernels may overheat and potentially ignite, creating a dangerous fire hazard.

Another food that performs poorly in air fryers is anything coated in wet batter. Many people love the crunchy coating on foods like fried chicken or battered fish, but air fryers are not designed for traditional liquid batters.

In a deep fryer, the batter quickly solidifies when it hits hot oil. In an air fryer, however, the batter often drips through the basket before it can cook properly, leaving behind a sticky mess and uneven coating.

Because of this, chefs recommend using dry coatings—such as breadcrumbs or flour—rather than liquid batter when preparing foods in an air fryer.

There are also practical concerns when it comes to relying too heavily on this appliance for every meal.

Financial expert Martin Lewis has pointed out that while air fryers can save energy in certain situations, they are not always the most efficient choice for every cooking task.

Speaking on the British television program This Morning, Lewis explained that air fryers are most efficient when used for small portions of food that cook quickly.

“If you’re cooking a single item or something small, an air fryer can be very efficient,” he said.

“But if you’re preparing many different foods separately, you may end up using the appliance multiple times. In those situations, a regular oven might actually be more practical.”

In other words, while the air fryer is excellent for quick snacks or small meals, it may not always be ideal for large family dinners.

Cooking several dishes in batches could take longer and use more electricity than simply cooking everything at once in a conventional oven.

Consumer experts have echoed similar concerns. Representatives from the consumer advocacy organization Which?

note that the cost savings of an air fryer can decrease if you regularly need to cook large quantities of food.
