A good air fryer with oven should be able to do more than just produce hot air. One of the most important features is high-temperature hot air circulation, to cook food evenly and crispy—with little or no oil. Multiple rack levels make it possible to prepare different foods at the same time, while a timer and temperature control ensure precise cooking.
Pre-set automatic programs, for example for fries, pizza, chicken, or vegetables, are particularly practical.
A rotisserie function (spit) is ideal for roast chicken or skewers, while a dehydration program allows drying of fruit or herbs. Defrosting and reheating functions also increase everyday usability.
Don’t forget a large viewing window with interior lighting to keep an eye on the cooking process. Additional comfort comes from an easy-to-clean interior, dishwasher-safe accessories, and—with modern devices—app or touch controls. If you value versatility, energy efficiency, and comfort, you should look for these functions when buying.
