Air fryers are all the rage right now, and you might wonder: Are they energy-efficient? The answer is yes, since air fryers use hot air with very little oil to cook whatever you're crisping up. And because they are significantly smaller than an oven, they also take very little time to heat up from room temperature to literally hundreds of degrees. In fact, in the time it can take to preheat an oven, an air fryer can cook an entire dinner. And unlike deep-frying, there's no waste oil to dispose of when you're finished.
