It started with a simple question: why do restaurant fries taste so much better than the ones you make at home? The answer wasn’t better oil, better potatoes, or even better cooks—it was a machine most people had never heard of. That machine, the air fryer, promised to deliver restaurant-quality results with a fraction of the guilt. Skeptics laughed it off as a gimmick. But by 2023, air fryers were selling at rates that outpaced even the rise of the Instant Pot. The shift wasn’t just about convenience; it was about rewriting what home cooking could be.
Today, air fryers sit in kitchens alongside slow cookers and blenders, but their role is different. They’re not just for frying—they’re for reinventing. From searing steaks to baking pastries, these countertop wonders have become the Swiss Army knife of modern cooking. Yet for all their popularity, many still wonder: air fryers are used for what, exactly? The answer is broader than most realize, spanning health, efficiency, and even sustainability. This is the story of how a niche appliance became a kitchen staple—and what it can do for you.
Where It All Began
The air fryer’s origins trace back to the early 2010s, when Philips introduced the first commercial model under the name "Airfryer." The concept wasn’t entirely new—it built on decades of research into convection cooking and rapid-air technology. But what set it apart was its promise: crispy food with little to no oil. The idea was simple: use a powerful fan to circulate hot air around food at high speeds, mimicking the effects of deep-frying without the mess or the calories.
Early adopters were mostly health-conscious consumers and those who wanted to cut down on oil usage. The appliance gained traction in Europe first, particularly in the UK, where diet trends leaned toward lower-fat alternatives. By 2014, Philips had sold over a million units, proving there was real demand. But the real turning point came when the air fryer stopped being seen as just a fryer—and started being recognized as a multipurpose cooking tool.
The Early Signs
The first wave of air fryer users were the pragmatic ones: people who wanted to enjoy fried foods without the health trade-offs. But as word spread, so did experimentation. Bloggers and food influencers began testing the appliance’s limits, discovering it could roast vegetables, bake cookies, and even grill chicken. The shift from "fryer" to "versatile cooker" was subtle but critical—it broadened the question from air fryers are used for what to how far can they go?
Manufacturers noticed. Brands like Ninja and Cosori entered the market with models that included additional functions, like dehydrating or air grilling. Suddenly, the air fryer wasn’t just about fries—it was about rethinking entire meal prep strategies. The appliance’s compact size also made it ideal for small kitchens and renters, further expanding its appeal.
The Turning Point
The air fryer’s breakthrough came when it stopped being a novelty and started being a necessity. The pandemic accelerated this shift, as home cooks sought appliances that could handle multiple tasks without taking up counter space. Sales surged in 2020, with some retailers reporting year-over-year increases of over 200%. But the real inflection point was when chefs began endorsing it—not just for frying, but for techniques like sous-vide finishing or even caramelizing onions.
What changed wasn’t just the technology; it was the mindset. People realized that air fryers could replace not just deep fryers, but also ovens, grills, and even stovetops for certain tasks. The question air fryers are used for what evolved into what can’t they do?—and the answer was surprisingly little.
"The air fryer is the closest thing to a magical kitchen tool we’ve seen in years. It’s not just about frying anymore—it’s about redefining how we cook at home."

Today, air fryers are no longer a niche appliance—they’re a kitchen staple. High-end models now include features like smart cooking presets, Wi-Fi connectivity, and even air roasting for larger quantities. Brands are pushing boundaries with designs that mimic professional-grade equipment, such as those with stoneware baskets for even heat distribution.
The question air fryers are used for what has been answered in ways few anticipated. They’re used for crispy chicken wings, perfectly baked cookies, and even seared scallops. They’re used by busy parents, health-focused athletes, and home chefs experimenting with fusion cuisine. And they’re used as a bridge between convenience and quality—delivering restaurant-style results without the restaurant-style hassle.
Conclusion
The air fryer’s journey from a health-focused fryer to a multipurpose kitchen workhorse is a testament to how innovation can reshape everyday habits. What started as a solution to one problem—enjoying fried foods without the guilt—has become a catalyst for rethinking home cooking entirely. It’s not just about air fryers are used for what anymore; it’s about what they enable.
As technology advances, so too will the air fryer’s capabilities. But one thing is clear: this isn’t just an appliance trend. It’s a shift in how we approach food—one that balances health, efficiency, and flavor in ways previous generations couldn’t have imagined.
Comprehensive FAQs
Q: Can air fryers replace a deep fryer entirely?
For most home cooks, yes—but with caveats. Air fryers excel at creating crispy textures with far less oil, making them ideal for fries, chicken nuggets, and similar dishes. However, they can’t replicate the deep, oil-bath cooking of some traditional fried foods (like beignets or certain Asian street foods). For everyday use, they’re a more than adequate substitute.
Q: Are air fryers better for health than traditional frying?
Generally, yes. Since air fryers use 70–80% less oil than deep frying, they significantly reduce calorie and fat intake. However, the health benefits depend on what you’re cooking. For example, air-fried foods can still be high in sodium if seasoned heavily. The key is moderation—air frying is healthier, but it’s not a free pass for fried foods.
Q: Can you bake cakes or cookies in an air fryer?
Absolutely, though with some adjustments. Air fryers work well for small batches of cookies, muffins, and even mini cakes. The rapid air circulation ensures even baking, but larger or denser baked goods may require longer cook times or preheating. Many recipes online provide specific air fryer instructions for these items.
Q: Do air fryers save energy compared to ovens?
Yes, significantly. Air fryers use about 1/3 to 1/2 the energy of a conventional oven for similar tasks. They heat up faster and cook more efficiently, making them both cost-effective and eco-friendly. This is especially useful for small portions or single-serving meals.
Q: Can air fryers be used for reheating leftovers?
They can, but with mixed results. Air fryers are great for reheating foods that benefit from crispiness, like fries or chicken wings. However, soupy or saucy dishes may not reheat evenly. For best results, use the air fryer for dry or slightly oily leftovers and avoid overly wet foods.
Q: Are there any foods that shouldn’t be cooked in an air fryer?
Yes. Foods with high moisture content (like custards or soups) can splatter or steam instead of crisp. Delicate seafood, such as shrimp or fish fillets, may dry out too quickly. Additionally, large cuts of meat (like whole chickens) require more space than most air fryers provide. Always check your model’s capacity and cooking guidelines.
Q: How do air fryers compare to other small appliances like Instant Pots or slow cookers?
Each has its strengths. Air fryers excel at achieving crispy textures quickly, making them ideal for snacks and quick meals. Instant Pots and slow cookers, on the other hand, are better for stews, braises, and dishes that benefit from long, slow cooking. Air fryers are more versatile for high-heat, short-duration tasks, while multi-cookers handle low-and-slow methods.
