Do Air Fryers Need To Preheat?
Contrary to what some first-time air fryer owners might believe, air fryers do need to preheat. Failing to preheat your air fryer is a surefire way to end up with partially uncooked meals.
Undercooked meats and veggies can harbour dangerous germs, causing unpleasant and potentially debilitating foodborne illnesses. Consequently, it’s essential to always preheat your air fryer before placing your food into the cooking chamber.
But why do air fryers need to preheat?
After all, a traditional fryer needs to be preheated because it contains cooking oil, which is what cooks the food. It has to be hot enough to penetrate each ingredient and raise it to safe temperatures.
But air fryers don’t use oil. So why should you preheat them? The answer lies in the technology behind air fryers: Convection cooking.
Air Fryers Are Convection Cookers
Convection ovens and cookers have been on the market for quite a while, but they’re not always associated with air fryers. However, air fryers are essentially souped-up convection ovens.
The central concept behind an air fryer and a convection cooker is the same. There’s a heating element, a fan, and a cooking chamber. When the user turns one of these devices on and sets a temperature, the heating element begins to produce waves of heat that excite the air around it.
These fast-moving waves are swept upward and throughout the cooking chamber by the fan. This continually heated air is circulated to ensure that the food is cooked from all sides at one time.
Any cool air that forms will sink toward the heating element and rise once again.
The primary differences between standard convection ovens and air fryers are size and design. Air fryers tend to be more compact than convection ovens. They also have cylindrical or egg-like structures, while convection ovens remain mostly box-like and cumbersome.
These differences have helped the air fryer become a kitchen staple.
After all, the smaller size and upgraded shape help air circulate more quickly, resulting in shorter cooking times and faster preheating. Because air fryers are essentially tiny ovens, they need to preheat.
Many People Put Frozen Foods in Air Fryers
Some of the most popular options for air fryer owners are frozen foods.
Because air fryers are rapid cookers, home chefs can freezer-to-plate meals in less than half an hour. However, this tendency to cook frozen meals in an air fryer can be problematic if you’re not preheating your device.
While many frozen foods are pre-cooked for your convenience, some are not.
For example, some companies parboil their meats before bagging and freezing them. But that doesn’t make them safe to consume after thawing.
If you’re not preheating your air fryer before heating chicken tenders, beef taquitos, or other frozen meat products, you could be opening the door to foodborne illnesses and parasites. To keep yourself safe from accidental food poisoning, always pay close attention to the recommended cooking temperature and times listed on your frozen foods.
Not only will preheating help keep your body safe from foodborne bacteria, but it can also significantly improve the quality of your air-fried meals. If you’ve been getting half-frozen fish sticks or partially-burned chicken nuggets from your air fryer, you may find that a little preheating makes all the difference.
Even Cooking Requires a Consistent Temperature
If you’ve ever lit a cozy campfire on a chilly night, you likely know that it took several minutes for the fire to warm you up. That’s because the air surrounding the fire started out cold and gradually warmed up as the fire continued or grew.
Air fryers function in the same way.
When you set the cooking temperature on your air fryer and activate it, the heating element kicks into life. But the cooking chamber doesn’t instantly become a sweltering oven.
That’s because it takes a little time for the internal fan to circulate the warm air throughout the device. Just like with a crackling campfire, the more time and fuel you put into it, the more even and intense the heat.
If your air fryer meals often come out unevenly cooked, the issue could be poor preheating practices. However, it’s worthwhile to note that these problems may also stem from overstuffing your cooking basket.
Still, high-quality meals require consistent temperatures. If you’re not preheating before cooking, you could be sabotaging your hard work. Just be sure that you’re preheating for the right amount of time.

How Soon Before Cooking Should You Preheat?
The precise amount of time you should allow your air fryer to preheat before cooking varies depending on the device, desired temperature, and ingredients. Higher-temperature meals tend to necessitate slightly longer preheating times, as do some frozen foods.
Raw meats may also require extended preheat sessions to ensure even cooking.
Taking the time to preheat your air fryer before preparing meats is also an excellent way to avoid common foodborne parasites and illnesses. However, none of this information offers a precise time for preheating an air fryer.
Word-of-mouth advice varies drastically, with some air fryer enthusiasts claiming that three minutes is enough and others demanding that anything less than ten minutes is risky. Truthfully, both of these statements have some truth to them.
Preheating is all about bringing your air fryer up to the ideal temperature for cooking a particular type of food. To figure out a reasonable preheating time, you’ll want to consider your meal’s listed cooking temperature.
Let’s take a look at some of the things you should consider when preheating your air fryer.
Consider the Desired Cooking Temperature
Some pre-cooked frozen or refrigerated meals cook at relatively low temperatures of 325℉ (162.77°C) or less. Other ingredients, such as thick pork tenderloins, might need much higher temperatures of about 400℉ (204.44°) or greater to achieve adequate doneness.
When preheating your air fryer, take a moment to consider the temperature and cooking time recommended for your chosen snack. Meals with low cooking temperatures that take less than ten minutes require the least amount of preheating.
Pre-cooked snacks and pastries often require a short three-minute preheat.
Frozen snacks might cook more evenly with a slightly lengthier, five-minute session. And, naturally, frozen or raw cuts of meat are always going to cook more effectively after ten minutes of preheating.
Still, if these sorts of internal calculations seem like too much additional work, you can always rely on the five-minute rule. If you forget everything else about preheating an air fryer, you can still enjoy top-notch meals by simply remembering that five minutes is an excellent preheat time.
Use the Five-Minute Rule
Sometimes it’s tricky to figure out the precise preheat time for an air fryer snack. Other times, we simply don’t have the patience to deal with thinking about it.
In these situations, you can always rely on the five-minute preheat rule.
Most air-fried meals take fifteen minutes or less to cook fully. The average air fryer should reach an optimal cooking temperature in ⅓ or less of that time. As such, five minutes could be the ideal preheating time, no matter what you’re cooking.
If you’re someone who benefits from simple reminders, the five-minute rule could be a game-changer.
Of course, having a more accurate means of measuring food temperature could help you eliminate potential foodborne illnesses for good. If you don’t currently own a meat thermometer, now might be the time to buy.
Invest in a Food Thermometer
If you’re preparing raw or frozen meats in your air fryer, you may want to invest in a food thermometer. While the five-minute rule is a great base to work from, it’s not entirely foolproof. After all, the surrounding air temperature isn’t always the same as the meat’s internal temperature.
For maximum food safety, it’s crucial to have an insertable meat thermometer on hand. Unfortunately, thermal thermometers can be challenging to use with air fryers because the air inside the cooking chamber can remain very hot for several minutes.
Remember, air fryers are essentially convection ovens. An insertable meat thermometer can provide more accurate readings, which is why it’s the preferred tool.
The ThermoPro Digital Meat Thermometer on Amazon.com is a fantastic example of an easy-to-read handheld meat thermometer. It features a bright backlit display with large numbers and a collapsible probe for safer storage.
This meat thermometer is also waterproof, allowing you to rinse it clean in seconds after each use.
Is It Dangerous To Not Preheat Your Air Fryer?
It is not dangerous to not preheat your air fryer, but it can result in lackluster french fries or steam vegetables, and it can pose a health risk when preparing certain meals. For example, raw meats that aren’t evenly cooked to a safe temperature can cause foodborne illnesses to spread.
Some of the most common dangers associated with eating undercooked meats include:
- Parasitic Infections
- Bacterial infections
Avoiding both of these types of infections starts with proper food safety and hygiene techniques. Storing your food safely and at the appropriate temperature can help your ingredients stay fresh for a longer amount of time.
However, ensuring that your meals are evenly and adequately cooked is also essential. Preheating your air fryer could help you avoid a wide range of illnesses, parasites, and uncomfortable symptoms.
Just an extra five minutes of waiting can help ensure that you never have to experience foodborne-related:
- Abdominal Cramps
If you have a compromised immune system, it is especially crucial to ensure the meats, vegetables, and dairy products you consume are safe and properly prepared. According to the CDC, an E. coli (Escherichia coli) infection can be mild for healthy, fit individuals but potentially fatal for others.
Can Preheating Your Air Fryer Cause Problems?
Preheating rarely causes mechanical problems or safety hazards. However, overheating your device can be dangerous. That’s why preheating times don’t go above ten minutes.
Most of the internal components in an air fryer are designed to withstand high heat for short periods. But plastic parts can begin to melt at extremely high temperatures.
Additionally, running your air fryer for an hour or longer, especially at higher temperatures like 400℉ (204.44°C), can cause it to catch fire. As such, it’s vital to never preheat for more than ten minutes, especially at higher temperatures, which is considered 350℉ (176.66℃) or more.
Fortunately, most air fryers are capable of cooking foods in less than thirty minutes.
If you have any specific safety or operation concerns, you can also refer to your particular appliance’s user manual. Most list helpful hints and safety guidelines to help you enjoy the best possible results.
You can also refer to a standard air fryer cooking chart to look up various cooking times for typical meals. Having such a chart handy in the kitchen could be a smart way to avoid overcooking your ingredients and overheating your air fryer.
