You can use a convection oven as an air fryer by relying on its fan to circulate hot air, using a low-sided pan or wire rack, and adjusting time and temperature.
If your oven has a convection setting or a dedicated Air Fry mode, you already own a machine that can produce the crisp results people buy air fryers for. The technology is the same—a fan moves hot air around the food—but the difference comes down to setup and technique.
What Makes a Convection Oven Work Like an Air Fryer
Air fryers are essentially small convection ovens; both use a fan to strip moisture from food’s surface, creating browning and crispness. A full-size convection oven does the same when you help it with the right cookware and placement. Food needs exposed to moving air on all sides. KitchenAid recommends an air fry basket or low-sided pan, set in the center for even airflow. Skip deep, high-sided dishes that trap steam and soften food. Keep the oven floor clear—KitchenAid cautions against anything that blocks airflow, and Maytag suggests a lower-rack tray to catch crumbs and drippings.
The Step-by-Step Method for Air-Fry-Style Cooking
This works for frozen fries, chicken tenders, vegetables, and reheating leftovers with a crispy edge.
- Prepare the food: Cut vegetables into small, even pieces. Pat meat or fish dry. For breading, use breadcrumbs or shredded cheese instead of wet batter, which steams rather than crisps.
- Choose the right pan: Use an air fry basket, a wire rack over a baking sheet, or a low-sided pan—the goal is air movement around every side.
- Keep food in a single layer: Overcrowding blocks airflow and turns crisping into steaming; cook in batches if needed.
- Preheat the oven: KitchenAid and Maytag both include preheating in their official guidance; a hot oven creates the immediate sizzle that leads to browning.
- Adjust time and temperature: Set the oven about 25°F lower than the air fryer recipe’s temperature, and check a few minutes before the expected finish. These are starting points, not fixed rules.
- Flip halfway through: Maytag and LG both recommend turning food halfway for even browning and crispness.
The single most important step is preheating. Skipping it adds cooking time and produces softer results—if food looks pale, the oven wasn’t hot enough when the food went in.
Temperature and Time Conversions That Work
Because the fan moves heat more efficiently than still air, convection ovens cook faster and hotter. The general adjustment is to lower temperature by about 25°F from an air fryer or conventional recipe and start checking for doneness roughly 20 percent earlier. These are heuristics, not universal specs—treat them as starting points and rely on visual cues more than the timer.
| Cook Mode | Temperature Adjustment | Time Adjustment |
|---|---|---|
| Air fryer recipe | Same or 25°F lower | Check 3–5 minutes early |
| Conventional oven recipe | 25°F lower | Reduce by ~20–25% |
| Dedicated Air Fry mode | Uses the mode’s default (often 400°F) | Follow the mode’s preset |
If your oven has a dedicated Air Fry mode, LG notes it may default to 400°F and require specific rack placement; some models offer preheat in Air Fry mode, others don’t. Check your manual for recommended rack position before starting.
Common Mistakes and How to Avoid Them
Most disappointing air-fry attempts come down to fixable errors. Crowding the pan is the biggest—food needs space for air. Wet batter creates a steam barrier that prevents crisping, and skipping preheat leaves food pale and soft. Smoke can also be a problem: LG notes greasy foods may produce smoke, Maytag recommends a tray below to catch drips, and Epicurious warns crumbs on the oven floor can burn and smoke later. Use a food thermometer and check often. If your oven lacks convection entirely, regular bake mode won’t provide the same circulating heat, so results will be softer.

FAQs
Can a regular oven air fry without a convection setting?
No. Standard bake mode uses still heat from the bottom or top element, which doesn’t move air around food. The fan’s circulation is what creates the crisp, browned exterior air frying produces.
Why did my food turn out steamed instead of crispy?
Steaming happens when food is crowded on the pan or coated in a wet batter—both block the moving air that creates crispness. Cook in a single layer, use breadcrumbs instead of batter, and ensure the oven is fully preheated.
Do I need a special basket to air fry in a convection oven?
No. A wire rack over a baking sheet, a low-sided pan, or an air fry basket all work. The key is that hot air reaches every side of the food; high-sided dishes trap steam and should be avoided.
