You can use a convection oven to mimic an air fryer by using a crisper basket, lowering the temperature by 25°F.
You’ve seen those crispy fries and golden chicken wings from an air fryer and figured you’d need to buy another appliance. The truth is simpler. An air fryer is basically a small convection oven with a focused fan, a design that speeds up browning. If your full-size oven already has a convection setting, you already have the core technology.
The catch is technique, not hardware. To get that air-fryer crunch from a regular oven, you need to adjust temperature, reduce time, and use the right cookware — mainly a perforated basket that lets hot air hit every surface. This guide walks through the exact steps and numbers so you can stop buying gadgets and start using what you own.
What Makes an Air Fryer Different
An air fryer heats food faster because its fan is closer to the basket and the chamber is small. Serious Eats explains the air fryer is a small convection oven cranking hot air around at high speed. That rapid circulation creates the crispness you expect.
Your convection oven’s fan is less powerful and the chamber is larger, so the same recipe takes longer and may not brown as evenly. The fix is simple: compensate with a higher temperature offset and a crisper basket that lifts food off the baking surface.
The goal is to replicate the air fryer’s environment — high heat, good airflow, minimal crowding. Once you understand that, the conversion becomes a matter of math and gear.
Why the Basket Matters
Many people set their convection oven to “air fry” mode and still end up with soggy fries. The missing piece is airflow underneath the food. A standard baking sheet blocks air from reaching the bottom side. The basket is the hero.
- Perforated crisper basket: Allows hot air to circulate all the way around each piece. This is the single biggest upgrade for crispy results.
- Half-sheet pan with wire rack: A wire rack works nearly as well, especially for larger items like chicken thighs or fish fillets.
- Avoid solid pans: No-sided or low-sided baking sheets are better than deep pans, but still reduce bottom airflow compared to a basket.
- Don’t overcrowd: Leave at least half an inch between pieces. Clumped food traps steam, which kills crispness.
The appliance manufacturers agree: Whirlpool and Maytag both recommend using proper cookware — not just the oven tray — to get use proper cookware for crispiness results close to an air fryer.
Conversion Rules That Work
When you find a conventional oven recipe you love, apply two changes: lower the temperature by 25°F (or 20°C) and reduce the cooking time by 20 to 25 percent. Epicurious recommends investing in a use a crisper basket for best results. These rules apply to vegetables, baked goods, and proteins alike, though thicker cuts may need less time reduction.
| Conventional Oven | Convection Oven (Air Fryer Style) |
|---|---|
| 400°F for 20 minutes | 375°F for 14–16 minutes |
| 350°F for 30 minutes | 325°F for 22–24 minutes |
| 375°F for 25 minutes | 350°F for 18–20 minutes |
| 425°F for 15 minutes | 400°F for 11–12 minutes |
| 200°C for 25 minutes | 175°C for 20 minutes |
These are starting points. Check food visually a few minutes before the lower end of the range, and flip halfway through for even browning.
How to Set Up Your Oven for Air-Frying
Getting the technique right matters more than the exact temperature. Follow these steps each time for consistent results.
- Preheat your convection oven to the target reduced temperature. Let it run for at least 5 minutes so the fan is moving hot air before food goes in.
- Prepare the food with a thin oil coating. Use cooking spray or a light toss in oil — about a tablespoon per pound of food. Oil aids browning and helps the crust form.
- Place food in a single layer in the crisper basket. Overlap only if pieces are very small, and expect to cook in batches for larger quantities.
- Flip or shake halfway through. For fries or nuggets, open the oven and give the basket a shake. For chicken or fish, flip each piece with tongs.
That last step is critical. KitchenAid recommends you flip food halfway through to ensure both sides get the same blast of hot air. Skipping it leaves you with one browned side and one pale side.
Temperatures and Times That Deliver
Different foods need slightly different settings. For vegetables like broccoli, Brussels sprouts, or potato wedges, start at 375°F after conversion. For chicken wings or breaded items, 400°F works well. The Instacart guide suggests you air fry vegetables temperature at a reduced value, typically 25°F below the original recipe. Cuts with more moisture, like salmon fillets, benefit from a smaller time reduction — aim for 15% less rather than 25%.
| Food | Convection Oven Temp | Approximate Time |
|---|---|---|
| Frozen french fries | 400°F | 12–15 minutes |
| Chicken wings | 375°F | 22–26 minutes |
| Bacon strips | 375°F | 8–10 minutes |
These times assume a single layer in a crisper basket. If your oven runs hot or your food is thicker, adjust down rather than up — you can always add a minute or two.
The Bottom Line
Using your oven like an air fryer comes down to three adjustments: drop the temperature 25°F, cut the time by roughly 20%, and use a perforated basket or wire rack. Add a light coat of oil and flip halfway through, and you’ll get results that rival a dedicated countertop appliance.
Your oven’s convection fan can handle most of the work — the basket and the timing are what turn an ordinary baked potato into something with a crispier skin. For recipes that call for large volumes, like a full sheet of chicken tenders for a crowd, your oven will actually outperform a small air fryer without needing multiple batches.
