What’s the Difference Between an Air Fryer vs Convection Oven?
At their core, both appliances work using a fan to circulate hot air around food, ensuring an even cook. But there are differences:
Air Fryer
- Compact countertop appliance
- Uses rapid air circulation
- Mimics deep frying with little to no oil
- Great for quick, crispy meals

Convection Oven
- Larger built-in or countertop oven
- Equipped with fan and exhaust system
- Provides even cooking
- Ideal for baking and roasting
Summary of Differences
The main difference between air fryer and convection oven lies in size, cooking speed, and design. Air fryers are faster and more compact, while convection ovens offer more space and versatility.
Cooking Time Comparison of air fryer vs convection oven
Thanks to their smaller chambers and concentrated heat, air fryers generally cook food 20–25% faster than convection ovens. Whether it’s chicken, frozen foods, or fries, air fryers win on speed.
