The Biggest Mistakes You're Making With Your Air Fryer

The air fryer was supposed to revolutionize the way we cook fried food. No more hazardous pots full of boiling oil. No more questions about what the heck you're supposed to do with all that oil when you're done with it. Most of all, no more greasy, fatty, fried foods. You get all the flavor with none of the guilt. Sounds too good to be true, doesn't it?

As it turns out, it is too good to be true — but only if you're making the mistakes that most people make when they buy an air fryer. Are your fries limp? Did your tortilla chips burn? Did your countertop melt? These are some of the most common problems people have with their air fryers, and they happen not because air fryers don't work as advertised, but because consumers don't yet understand the subtle nuances of these still relatively-new devices.

If this is you, don't worry. There's no need to wonder if the manufacturer will take back your used, maybe not perfectly clean, air fryer. Chances are, there's nothing wrong with it. You're probably not getting the perfectly cooked, low-fat food of your dreams because you're making some of these very common mistakes. Let's take a look at what to avoid.

For some people, cooking healthier versions of snacks like chips is a big selling point of the air fryer. But after scraping a few scorched kale chips off the heating element, well, let's just say the honeymoon ends there. The air fryer is a convection device, which means it works by blowing hot air around, per The Spruce Eats. The food sits in a basket that has holes in the bottom so the air can circulate on all sides of your french fries, chicken patties, or whatever. The hot air will color the food and make it crispy if all goes well.

But the keyword here is "air." What happens when you're outside having your lunch on a picnic table, and the wind picks up your sandwich bag? You end up chasing your sandwich bag around the park. The same thing happens in your air fryer. The "wind" blows the light stuff around. At best, you end up with a quesadilla without a top. At worst, you get a batch of scorched kale chips.

Fortunately, the solution to this is pretty simple. Ninja advises air fryer users to secure the light ingredients with a toothpick. This doesn't help much if the problem is kale chips, though. For that problem, food bloggers popularly recommend putting a rack over the chips to keep them in place (via Whole Lotta Yum).

Some home cooks seem to have the opposite problem — they're treating the air fryer like a deep fryer. Let's forget for a moment how little sense this makes, since the central selling point of an air fryer is that you can fry food without all the fat. Still, some people seem to be making this mistake.

So what happens if you use too much oil in your air fryer? Well, for a start, The Washington Post says you'll get soggy food. This is the opposite of what you want, since the whole point of frying anything, no matter what technique you use, is that the result will be crispy.

But that's not even the worst thing that can happen. Food that's overloaded with oil will drip, and when the oil leaks, it ends up under the basket on the hot bottom of the fryer. When this happens, the fryer will smoke and may even overheat (via Kitchen Appliance HQ). So the best thing that can happen is you'll get food that's soggy and less healthy than it should be, and the worst thing that can happen is you'll wreck your not-so-cheap machine.

Air fryers aren't really a budget-friendly appliance. You may find yourself wondering if you can get away with buying a smaller cooker, because the 4-quart one is half the price of the 8-quart one. If you make this decision based on price alone, you may end up regretting your purchase. According to Taste of Home, a 2-quart air fryer is only suitable for someone who cooks for themselves and maybe one other person, provided you're both light eaters. If you frequently cook for yourself and one or two other people, you might be able to get away with a 3-quart cooker, but a 4-quart model will be a lot more versatile.

If you have a family of four, go for a 6-quart model. If you have a large family or you like to host dinner parties, you may need an extra-large model with something like an 8-quart capacity. So what if you get something a little too small — can't you cook in batches? Sure, you can, but you're going to regret this when you're on your fourth batch of fries, and the first batch is already getting cold. It may seem like a good money saving-idea now, but in the long run, you're probably going to decide that using your air fryer is too much hassle, and then you might as well have not spent the money at all.

If you want French fries but would rather not slice them up yourself, you can just cook a batch of frozen fries in the air fryer. It's quick and easy, and you also get that nice crispy fried texture that you can't really duplicate when you do them in the oven. According to Taste of Home, you can buy packaged, frozen foods like chicken tenders and egg rolls and just put them straight into the air fryer, with perfectly crisp results. Don't thaw these products first. If you do, you're just wasting your time and may even end up with poorer quality food.

Taste of Home even recommends cooking frozen salmon filets in your air fryer, straight from the freezer, though other sources beg to differ. Pretty much everyone — including the USDA — agrees that it's safe to cook frozen fish and meat, as long as you're very sure it's done when you take it out of the fryer. You can use an internal thermometer to check. The problem is really quality. Raw meat cooked from frozen tends to be soggy and has less flavor than meat that's been thawed first, so it's probably worth the extra step to put it in the fridge the day before you plan to cook it (via Bon Appétit).

The good news is, you don't have to put your French fries in a single layer on the bottom of the basket. Overfilling doesn't necessarily mean you can't have pieces of food touching other pieces of food. According to Ninja, it's fine to put a pile of fries into their air fryer's basket. The key is to make sure to shake the basket periodically during cooking, so all or at least most of the fries get good contact with the circulating air.

It's still important not to overload the basket — if there are too many fries, no amount of shaking will make them all crispy. And even when you have things you're cooking in one layer, like a row of chicken strips, you still need to open up the basket halfway through the cooking process to flip them over (via Cook's Illustrated). This helps them cook evenly and ensures a uniform golden color on all sides.

All air fryers are not created equal, so cooking with one is a little trickier than cooking with a standard oven. As long as your oven is performing correctly, for example, you can be pretty sure it will take 12 minutes to bake a batch of cookies at 350 degrees if that's how long the recipe says it will take. 

With an air fryer, though, it's different. The most important thing you can do when you first take your air fryer out of the packaging is read the manual. According to Livestrong, not every air fryer recommends the same cooking times for the same types of food. This is because every manufacturer designs their fryer differently, so what takes 12 minutes in one fryer might take 15 in another.

And don't forget that some fryers have bells and whistles that you might miss out on if you don't thoroughly educate yourself about what they can do. Some models, for example, have a two-basket system that lets you cook two different foods simultaneously. Others have separate bake, roast, and fry settings. So if you don't understand all the quirks of your model, you may not be taking full advantage of all the things it can do.

Finally, we need to talk about safety. You may have heard that air fryers sometimes catch on fire or even explode. Thankfully, there aren't a lot of recorded incidents of this kind of thing happening. But according to New York Post, in the fall of 2021, a college student's air fryer exploded because she left it on her stove and accidentally turned the burner on, so we're going to say that wasn't the manufacturer's fault. In fact, Consumer Alert Now says most air fryer fires and explosions happen because of improper use, including adding too much oil or other mistakes like submerging the fryer in water to wash it.

According to Air Fryer World, you can't be too cautious with your air fryer. Make sure you pull it away from the wall while in use and leave plenty of space on all four sides for the air to circulate. If you're going to use parchment paper inside of it, make sure there's plenty of weight on top of it. If the paper isn't weighted down, it could blow around, meet the heating element, and catch fire.
