Don’t use a wet batter or coating.
But in an air fryer there is nothing to set a wet batter — it will just drip off while the food cooks. If you’re after crunch, dredge your food in flour, egg and breadcrumbs instead.
Why do I want an air fryer?
The extra-hot cooking chamber lets dry heat penetrate the food from the outside in, yielding the familiar crispy texture food gets with a bath in the deep fryer. As a bonus, cooking in an air fryer can save you time and it makes cleanup easy.
