Air Fryer VS Convection Oven: Which Is Better?

Share

An air fryer and an oven are popular kitchen appliances that are often used to prepare similar dishes. Before comparing performance, let’s quickly review how an air fryer works. Despite seemingly similar purposes of Air Fryers and ovens, these devices differ in design, operating principles, and functionality.

If you’re deciding which appliance fits your lifestyle best, this article breaks down when an air fryer truly makes sense — and when an oven is the better choice

. Let’s take a closer look at Air Fryer VS Oven characteristics.

Dimensions

✔Built-in ovens and countertop mini ovens typically measure around 60 cm in width, 55–60 cm in depth, and approximately 60 cm in height.

✔Both independent and dependent built-in ovens are installed permanently and are not designed for mobility.

✔Due to its larger size, an oven allows you to cook multiple dishes at the same time or prepare large, bulky meals

✔An air fryer is significantly more compact. On average, most models measure around 30 × 30 × 30 cm.

✔Easy to place. Thanks to its compact size, an air fryer can be positioned on a countertop or even stored inside a kitchen cabinet when not in use.

✔Limited capacity. Preparing large dishes in a standard air fryer can be more challenging. To see which compact air fryer performs best, read our complete review of the best air fryer for one person.

Connection

✔An oven requires a dedicated power outlet, and if it’s a gas model, it must also be connected to a gas line.

✔Only needs a standard electrical outlet. It can be used almost anywhere electricity is available.

Cooking Time

Long preheating: A traditional oven needs to be preheated, usually for 10–15 minutes or even longer.

Longer cooking process: Food cooks evenly throughout the large chamber, which often increases overall cooking time.

Fast heating: An air fryer heats up almost instantly thanks to its heating element and forced hot-air circulation.

Reduced cooking time: The compact chamber and continuous airflow allow food to cook 10–30% faster than in a conventional oven. This speed advantage also affects energy consumption — learn more in our detailed breakdown of air fryer vs oven electricity usage.

Crust Quality — Which One Does It Better?

Classic baked crust: With the right temperature and settings, especially using grill or convection modes, an oven can produce a traditional crispy crust.

Golden and crunchy: Powerful hot air circulation creates a dense, crispy exterior on meat and fish, similar to deep-fried results but without excess oil.

Cooking Programs

✔ Most ovens come with basic modes such as top and bottom heat, convection, and grill. Temperature and cooking time usually need to be set manually, and close monitoring is required to avoid undercooking or burning food.

✔ Many models feature preset programs that automatically adjust temperature and time for specific dishes. Simply select a program and press a button. This makes air fryers especially beginner-friendly.

Cleaning

✔ Regular use means more effort when cleaning. Grease and food residue build up on the interior walls, and hard-to-reach areas can be difficult to clean. However, premium ovens may include self-cleaning or pyrolytic functions that simplify maintenance.

✔ Most air fryers have removable baskets, trays, and racks that are easy to wash by hand or in a dishwasher. Cleaning usually takes just a few minutes. New users are sometimes concerned about odors, so here’s why an air fryer might smell like plastic.

Price

✔ Prices vary widely. Basic mini ovens can be affordable, but advanced models often cost more than high-end air fryers.

✔ Affordable and practical. Budget models are inexpensive, mid-range options are reasonably priced, and even premium air fryers often cost significantly less than top-tier mini ovens.

Cons:

  • Long preheating time, which increases overall cooking duration
  • Higher cost, especially for modern or multifunctional models
  • More difficult to clean due to its size and hard-to-reach areas
  • Older models may cook food unevenly
  • Requires significant kitchen space and is usually built-in

Final Verdict: Which One Is Right for You?

An oven is a great choice if you:

  • Regularly cook large portions or multiple dishes at once, especially for families of three or more
  • Have a spacious kitchen and room for built-in or large appliances
  • Enjoy traditional baking and roasting whole chicken, duck, or fish, and want maximum cooking versatility

An air fryer is ideal if you:

  • Cook in small quantities, suitable for households of up to three people
  • Have limited kitchen space and need a compact appliance
  • Value mobility and want a device that can be stored easily or taken with you
  • Want to save time on preheating and cooking
  • Prefer healthier cooking with minimal or no oil

Unlike built-in ovens, air fryers need open space around them, which makes placement important—this article explains where an air fryer should be placed in the kitchen.

Best-case scenario: if space and budget allow, using both appliances can be the perfect solution — an oven for large, complex meals and batch cooking, and an air fryer for quick, healthy, everyday dishes.
