Preheating an Air Fryer – And Why Your Food Will Taste Better Because of It

Get the Most Out of Your Air Fryer With These Preheating Tips

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.

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.

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. 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: Firstly, 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. Parchment 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.

You should be dry brining your steaks — here’s why
This is the easiest way to get the most flavor out of your meats
Dry brined steaks

When the word "brine" comes to mind, you may imagine yourself the night before Thanksgiving, wrestling a 19-pound turkey, trying to fit the thing into a container large enough to hold it and the salty water bath you're submerging it into. It isn't always the most fun activity, sometimes resulting in slippery poultry skidding across the kitchen floor and spewing curse words that make your visiting pearl-clutching mother-in-law blush. Thankfully, today, we're discussing dry brining, a much easier, much less stressful way to tenderize and flavor your proteins, and a new way to cook steak.
Essentially, dry brining is just a fancy culinary term for salting, then resting meat. And it's certainly not just for turkey. When you salt a piece of beef, pork, or poultry and allow that salt to penetrate the meat, you're creating flavor magic. When a piece of protein is seasoned with salt, it draws the juices from the meat to the surface. After a few minutes, that juice will break down the salt, which creates a concentrated dry brine. When left to rest in this way, meat becomes far more flavorful and tender than if you'd merely seasoned the meat right before cooking.
Furthermore, everything you dry brine, from steak and chicken breasts to pork chops, will have a far more even, beautifully golden, crispy crust. This is because the moisture that draws back into the meat after salting creates a much drier surface. And a dry surface is a deliciously golden one when cooked.
The recipe below is a beautifully simple one from Omaha Steaks, walking you through how to dry brine a steak, but this method to make steak will work on just about any protein you can think of, so get creative! And maybe next Thanksgiving, skip the water bath.

11 fantastic foods that are high in fat and low in carbs to support your health
Add these healthy foods to your grocery list today
A balanced Mediterranean-style breakfast with eggs

For a long time, fat has had the reputation of only being bad and capable of "destroying our health." Any food that was considered high-fat was an automatic no-go for those who were trying to diet or eat healthily. Yet, the 1990s low-fat diet fad failed when it came to solving numerous health problems, so people turned to other diets, like Atkins, South Beach, and keto, and foods high in fat and low in carbs became more acceptable.

Though some of these high-fat and low-carb diets have their own issues, experts have since come around to recommend balanced eating plans that include enough of the nutrients we need to live better. The good news here is that fat has always been part of a well-balanced eating plan; the quality and source of the fats consumed are where the real question lies.

A doctor tells us why the latest TikTok trend might actually be a problem for your health
Is this new TikTok 'trend' the start of something great? Or are we too far gone?
Man eating a big burger.

If you've grown up in the States, chances are, the idea of an "eat what you want" diet sounds too good to be true. That's likely because of the toxic, all-consuming diet culture we've been submerged in for the last several decades. Between fad diets, ridiculous "miracle" workout equipment, supplements that don't do a damned thing, and social media influencers making everything even more confusing, being told to "eat what you want" is, frankly, a little rattling.
The idea is a good one, albeit hardly a new revelation. Instead of restricting certain foods — which, most certainly, causes you to crave those particular foods more than you ever would have in the first place — indulge in them. Go ahead and enjoy that pepperoni pizza, those greasy french fries, or that bacon cheeseburger. Just eat less of it, then add in the healthy stuff that your body actually needs to thrive.
TikTok is full of videos setting examples of what this "new trend" might look like at mealtime. This example from user lizaslosingweight shows one thoughtful eater indulging in a favorite — instant ramen. Only, instead of making two or three packages and eating them solo, she makes one package and tops it with the good stuff — protein in the form of steak and eggs, and a variety of vegetables.
