Air Fryer vs Convection Oven: What's the Difference?

If you’ve ever read that an air fryer is “just a small convection oven,” you’re half right. Both cook with a fan that blows hot air around the food. But the size of the chamber, the strength of the fan and the shape of the basket make them cook quite differently. Here’s how they compare, and how to move recipes between them.

Is an air fryer a convection oven?

Technically, yes: an air fryer is a compact convection oven. A heating element sits just above the food, and a strong fan pushes hot air down and around it. A convection oven also uses a fan, but it’s usually mounted in the back wall of a much larger oven cavity.

What makes an air fryer different is concentration. The cooking space is small, the fan is close to the food, and the basket is perforated, so hot air reaches every side at once. That’s why air fried food browns faster and gets crispier than the same food in a convection oven.

Air fryer vs convection oven at a glance

	Air fryer	Convection oven
Size	Countertop, usually 2–8 quarts	Full-size oven or large countertop oven
Fan	Strong fan right above the food	Fan in the back wall, farther from the food
Preheating	2–5 minutes, or none	10–15 minutes
Cooking speed	Fastest	Faster than a regular oven
Crispiness	Very crisp, close to fried	Golden, but less crisp
Capacity	1–4 servings per batch	Whole meals, large roasts, several trays
Best for	Fries, wings, frozen foods, reheating	Roasts, sheet-pan dinners, baking, big batches
Cleanup	Dishwasher-safe basket on most models	Trays plus the oven interior

When an air fryer is better

• Small batches. For one to four servings, an air fryer is ready faster and finishes sooner.
• Crispy food. Fries, wings, potatoes, breaded fish and frozen snacks get noticeably crunchier.
• Reheating. Leftover pizza, fries and fried chicken crisp up again instead of going soggy. See our reheating guide.
• Hot kitchens. It doesn’t heat up the whole room the way an oven does.

When a convection oven is better

• Feeding a crowd. A convection oven can roast a whole chicken, a turkey, or two sheet pans of vegetables at once.
• Baking. Cakes, cookies, bread and casseroles have room to rise and bake evenly.
• Large cuts. Roasts and big pieces of meat that don’t fit in a basket.
• Wet foods. Saucy dishes and casseroles that would drip through a basket.

How to convert times between them

• Convection oven to air fryer: keep the same temperature and cut the time by about 10%.
• Regular oven to air fryer: lower the temperature by 25°F and cut the time by about 20%.
• Air fryer to convection oven: keep the same temperature and add about 10% to the time, using a single layer on a rack.

Every appliance runs a little differently, so check a few minutes early the first time. Our oven to air fryer conversion calculator does the math for you, and the cooking times chart lists times for more than 100 foods.

How to air fry in a convection oven

You can get close to air fryer results in a convection oven, or an oven with an “air fry” setting:

1. Use the convection or air fry setting, at the temperature the air fryer recipe calls for.
2. Use a perforated tray or a wire rack set on a baking sheet, so air reaches the underside. An air fryer basket made for ovens works well.
3. Spread the food in a single layer, with space between pieces.
4. Use the upper-middle rack, closer to the heat.
5. Add a few minutes to the air fryer time, and turn the food halfway.

What about air fryer ovens?

Air fryer toaster ovens are countertop convection ovens with a stronger fan and an air fry tray. They hold more than a basket air fryer, often enough for a 12-inch pizza or a small chicken, and they can bake and toast too. The trade-off is that they take up more counter space and usually crisp a little less evenly than a basket. Our air fryer size guide explains how much each size holds.

Which should you get?

If you already have a convection oven, an air fryer is still worth it for quick, crispy, small-batch cooking, and for not heating the full oven on a weeknight. If you’re choosing just one appliance for a small household, a basket air fryer or an air fryer oven covers most everyday cooking. Large families who bake and roast often will still want a full-size oven.
