It’s the latest food fad that doesn’t seem to be going anywhere, the healthy cook’s dream, the now hallowed and exalted air fryer. The hype around this countertop wonder doesn’t seem to be dying down, either, with new recipes and rave reviews popping up everywhere in recent years. Boasting the ability to prepare healthier versions of countless foods, from “fried” chicken to potato chips, by using little to no oil, it’s no wonder the air fryer has such adoring fans.

How does an air fryer work?

The science behind the air fryer’s magic is really quite simple. It works similarly to a convection oven by circulating air around the food at very high temperatures, causing the food to crisp and brown without the need for added fats. Deep-fried flavor without the deep-fried calories? Not a bad deal. But as this handy gadget is still a relative newbie to the kitchen counter, there are still things to learn about this little appliance and how to best operate it.

Something to keep in mind is that air fryers produce very high temperatures very quickly. Unlike an oven that takes a good bit of time to preheat, an air fryer will preheat in just a short amount of time. While this is very handy in a lot of cases, the quick heating time also makes it easier to burn food, so use those timers carefully!

Are you supposed to preheat an air fryer?

To put it simply, yes. Most foods, particularly those cooked in an air fryer, will benefit from a sudden blast of high heat. This interaction creates browning and crisping, whereas a slow, more gradual heating (like what happens if you don’t bother preheating and just stick your food into a cold air fryer) won’t have quite the same effect.

In addition to flavor and texture, preheating your air fryer will also prevent uneven cooking in your dish. You’re more likely to have cold spots or areas that are overdone if the air fryer isn’t given a chance to preheat. This is especially true when reheating leftovers, which is also something that can be done in your air fryer. Depending on your dish, you’ll find you get a much fresher, crispier result than you would in a microwave.

So while it isn’t technically a requirement — some models don’t even have a preheat setting — it’s still a crucial step as far as flavor is concerned.


How do I know when my air fryer is preheated?

Of course, all brands and models will vary in their features, but learning how to preheat an air fryer could be tricky. Many air fryers now have preheating options and alerts. If, however, your model doesn’t have this feature, the basic preheating guideline is to use the “air fry” setting, adjust your machine to the temperature your recipe calls for, and simply manually preheat for three to five minutes.

A few tips for successful air fryer preheating: First, always be sure that your fry basket is inside the unit when preheating. This is the part of the machine that will actually be in contact with your food, so it must therefore be preheated as well.

Second, if you’re using parchment paper to line your fry basket, it should not be inside the unit while preheating. Because of the convection fan inside, the parchment may blow into the heating coils and burn. The parchment paper must be weighed down underneath the food you’re cooking. Silicone liners are widely available and should be heavy enough to avoid this issue. Of course, always consult the packaging of your specific product to avoid any safety issues.

Now that we understand a few more of the rules of this trendy appliance, we can enjoy its popularity with perhaps a bit more ease. So don’t be afraid to jump on the air fryer bandwagon and get into the hype. With all of the calorie-cutting, time-saving, and delicious goodness to be derived from this little machine, this is one food trend it’s okay to enjoy.

9 tips on how to roast a juicy whole chicken
Here are some tips to elevate your roasted chicken to new heights
Close-up of a roasted chicken on a cutting board at a table

There's a reason chicken is the most popular meat in America. Whether fried, broiled, sauteed, poached, braised, or boiled, it remains delicious. Roasting chicken is one of the more ancient forms of cooking chicken that is still used today. When man first started cooking the bountiful birds, they didn't have boiling pots or saute pans, just some sticks and an open fire. This radiant heat form of cooking is today more widely known as rotisserie.

How to roast a chicken is commonly answered by roasting it over an open fire, which is still a perfectly acceptable method of preparing your poultry. But it's now most commonly done in an oven with dry heat. If you prefer calling cooking in the oven baking, that's fine since the terms baked and roasted are often used interchangeably. However, if you want to split hairs, the term baking typically implies some other sort of carb-based ingredients, such as breading. Think classic shake and bake. With roasting, it's typically just the meat and some seasonings or perhaps a glaze.
