When it comes to modern-day cooking, convenience meets health in a battle between two popular kitchen gadgets: air fryers and convection ovens. Both promise crisp textures, shorter cook times, and better nutrition than traditional deep frying. But are they really interchangeable? And which one should you invest in? In this extensive review, we compare features, benefits, limitations, and real-world usability to help you make an informed decision.
What is an Air Fryer?
An air fryer is a compact countertop appliance that uses hot air circulation to cook food, mimicking the results of deep frying—without submerging anything in oil. It typically features a basket or tray system and heats up quickly.
What is a Convection Oven?
A convection oven is a full-sized or countertop oven with a fan and exhaust system that circulates hot air. Unlike regular ovens, this circulation leads to even cooking and faster results.
