A few years ago, I wrote a cookbook on air frying. I vowed from the beginning to only develop recipes that benefited from being cooked in a special gadget by at least one of two metrics: The food is cooked dramatically faster than traditional methods — good for time-crunched cooks, or anyone who doesn’t want their oven on for hours in the middle of summer — or it drastically improves the quality or texture of the dish over other methods such as oven-roasting or actual deep-frying.
I was surprised to learn that all vegetables score high on both scales. In the air fryer, they cook faster and the high, dry heat circulating around them gets them golden brown to a degree that I’ve never achieved in a conventional oven alone.
I found squishy, spongy and sometimes slimy vegetables including eggplant, okra and, particularly, summer squash and zucchini are transformed completely in the air fryer, a vast improvement over their oven-roasted counterparts.
In an air fryer, they get blistered and caramelized and partially dehydrate — an effect of the fan in air fryers that blasts heat around them like a jet turbine. In the air fryer, more water inside the vegetables is removed, concentrating their flavor. Ever since, I have been air frying summer squash because its oft-maligned wateriness and lack of flavor is no longer an issue — and it takes half the time to cook.
