Air Fryers: What They Can and Can't Do, and Better Alternatives

When you think of an air fryer, a countertop appliance that uses rapid hot air to cook food with little to no oil. Also known as hot air fryer, it’s become a staple in UK kitchens for quick, crispy meals without the deep fryer mess. But here’s the truth: it’s not magic. It won’t handle wet batter, soups, or big roasts. And if you’re buying one thinking it replaces your oven, you’re setting yourself up for frustration.

Many people don’t realize that convection ovens, full-sized ovens with fans that circulate hot air for even cooking. Also known as fan ovens, they’re often better for larger meals and more consistent results. They’re bigger, sure, but they cook whole chickens, casseroles, and baked goods without the cramped space of an air fryer basket. Then there’s the toaster oven, a compact oven that toasts, bakes, and reheats with more flexibility than an air fryer. Also known as countertop oven, it’s a quieter, more versatile option if you don’t need the "fry" effect. If you’re cooking for two or three, a toaster oven with a bake setting might do more than your air fryer ever could.

And let’s talk about what you can’t cook in an air fryer. Wet batters? They drip, stick, and make a mess. Cheese-heavy dishes? They melt into a sticky trap. Large roasts? Too big. Soups or stews? Forget it—those belong on the stove. Even bacon can splatter and smoke if you don’t line the basket. These aren’t myths—they’re physical limits built into how air fryers work. If your kitchen space is tight and you want crispy chicken wings or frozen fries, an air fryer makes sense. But if you want to roast a whole vegetable tray, bake cookies, or reheat leftovers without drying them out, you’re better off with something else.

The posts below dig into exactly these issues: what air fryers can’t do, what you should avoid cooking in them, and the real alternatives that might be smarter buys. You’ll find honest takes on why some people regret buying one, and what actually works better for everyday meals. Whether you’re thinking of buying one, already own one, or just want to know if you’re wasting your money, you’ll find answers here—no fluff, no hype, just what actually happens in real kitchens.
