Knowing how to use your air fryer safely will not only make it last for longer, it can help you towards a healthier life too. You'll already know not to overheat it or use sharp utensils in the baskets, but you might be using an ingredient in your recipes that is doing a lot more damage.
If you haven't invested in one of the best non-toxic air fryers (which are lined with ceramic and stainless steel) you'll need to be careful with what you put in your air fryer. In a recent conversation with Sam Milner, author and air fryer chef, she revealed a surprising ingredient that could be doing some serious damage to your non-stick lining.
We talked about what to look out for, alternative options, and other ways to use your air fryer safely. Milner is full of tips on how to extend the life of your air fryer too, most of which center around keeping the non-stick in pristine condition. Here's everything you need to know.
Why do people think air fryers are toxic?
A year ago, the question 'are air fryers toxic?' went viral on TikTok. I've done a deep dive into it, but if you want the headlines, if your air fryer is used appropriately and remains undamaged it's fine. Issues arise when the non-sticks lining of the baskets (made with PTFE, PFOA, PFOA, and BPA) become damaged. Whether you scraped it or used a tough chemical on it, as soon as your non-stick is damaged, you risk ingesting some of it.
Pam Harnett, Registered Dietician and Public Health Expert told me that 'damaged non-stick coating can cause toxins to be released into the air and food. These chemicals can interfere with our hormones. I've seen links between these and several health issues, including reproductive and developmental issues.'
There's no need to panic though. That's an extreme. There are plenty of scientific papers from the National Institutes of Health that say that there's very little evidence that these chemicals will have adverse health effects when ingested in small quantities, but it can never hurt to be cautious.
What's the ingredient that's ruining your non-stick?
In a recent interview, Sam Milner, author of The Complete Air Fryer Cookbook, was giving me some pearls of wisdom for how to make your air fryer last longer. Amongst these, Sam mentioned a mistake that we are all making, which is damaging the non-stick of our air fryers.
She said 'People love air fryers because you can crisp up food without using much oil, but these really health-conscious cooks buy those light, low-calorie oil sprays. If you turn them around, these oils have very scary ingredient lists.' The key culprit for damaging your air fryer is an emulsifier called lecithin. When heated, this will slowly break down the non-stick coating inside your air fryer baskets.
There's no need to worry though, Sam has a simple substitute. 'Just use olive oil instead. You can buy 'you can buy olive oil sprays as long as you check the ingredients first. Failing that, buy an oil spray bottle and fill it with extra-virgin olive oil, making your own mist.'
If you don't fancy the full-fat option, Sam says 'balsamic or white wine vinegar are great options, because they'll stop your food from drying out and they'll add flavor too'. Sam has lots of vinegar-based recipes demonstrating how you can make the substitution in her Complete Air Fryer Cookbook. Make sure you check out the balsamic chicken: it's gorgeous.
Other tips for how to use your air fryer safely
Sam is full of suggestions for how to use your air fryer safely. She recommends investing in some silicone cooking utensils since these won't scratch the bottom of your non-stick, ruining your lining.
She says 'In our kitchen, we've got loads of air fryer accessories, but the best ones are silicone baskets. They'll mean that you're not cooking in the bottom of your air fryer baskets, so you're less likely to damage them. Plus, they'll save you on washing up.'
If you ask other experts for advice on how to safely use your air fryer, you'll get a pretty standard list of safeguards:
- Don't overfill your basket: this will stop air from circulating properly, so some parts of your meal will burn before others are even cooked. Plus, it'll make yours much less efficient.
- Don't mix and match: if you have multiple air fryers, don't use the baskets and accessories interchangeably, because they'll be designed to specifically suit the mechanisms of the brand's air fryer.
- Keep an eye on the cooking: it sounds obvious, but some people don't convert the cooking times and end up burning their food beyond savoir. This is why viewing windows can be really handy
- Keep it cool: Megan Hilbert, registered dietician and nutritionist, says 'if you're not air-frying at temperatures above 500 degrees Fahrenheit, you don't have much to worry about. Thankfully, most air fryers don't reach over 450 degrees, so this shouldn't ever be an issue. It's worth knowing though.'
Catherine Rall, certified Nutritionist at Happy V, said that 'Your best bet is to invest in an air fryer that doesn't have a synthetic lining. The advantage of a synthetic lining is that it's easy to clean, but if this comes at the expense of your health, it's simply not worth it'. We've got plenty of suggestions for non-toxic air fryers, which use stainless steel, ceramic, silicone, or organic linings. Luckily, with these, low-calorie oils are safe to use too. Here are my three favorites.
This is more than just an air fryer. It's a multicooker, offering you slow cooking as well as speedy meals. The coating is stainless steel, which might need more scrubbing, but it's non-toxic.
If you love your air fryer for its speedy delivery of tasty food, you won't do better than this. The name suggests that it's big, but this is actually Ninja's compact offering. It's coated with ceramic, a simple but effective non-stick.
This is one of the most underrated air fryers on the market. It's compact, with a neat viewing window, and helpful pre-sets. The lining is ceramic too, so you don't need to worry about using oil sprays.
FAQs
What precautions should be taken when using an air fryer?
If you want to keep your air fryer in top condition, you need to make sure that you clean it thoroughly after use. People will also suggest lining it with baking paper or silicone baskets so that you don't leave any stray crumbs behind.
It's also important not to use utensils with sharp ends, because these could damage the non-stick, as will any aerosol sprays. Also, don't let your air fryer overheat, because this can also affect the non-stick.
Is it safe to leave the house with an air fryer on?
Never leave the house with the air fryer on. These are hot appliances and could cause a fire if left unattended. You shouldn't need to leave the house, because air fryers are so speedy, you'll also miss your food being cooked. It's better to stay nearby at all times. Plus, if you're close by, nobody can steal your share of the fries.
