Why air fryers need lower temp and less time
An air fryer is essentially a small, powerful convection oven — a compact chamber with a fan that circulates hot air much more intensely than a full-size oven. That aggressive circulation cooks food faster and browns it more at the same temperature, which is why recipes need adjusting rather than just shrinking the pan size. The widely-used rule of thumb — drop the temperature by about 25°F and cut the time by roughly 20% — comes from air fryer manufacturers' own conversion guidance and holds reasonably well across most foods, though it's a starting point rather than a guarantee, especially for foods you haven't air-fried before.
Why you should still check early
Air fryer models vary more in actual cooking intensity than ovens do — basket-style air fryers, oven-style air fryer/convection combos, and different wattages all cook at somewhat different real speeds even at the "same" set temperature. The safest approach with any converted recipe: check food a few minutes before the calculated time, especially the first time you make something in your specific air fryer, and adjust future attempts based on what you learn.

FAQ
Does this work for baking, not just frying-style foods? The temperature/time adjustment applies broadly, but delicate bakes (cakes, soufflés) are more sensitive to an air fryer's smaller, more intense cooking chamber — expect more trial and error there than with roasted vegetables or reheated foods.
Should I preheat the air fryer? Most manufacturers recommend a short preheat (2-3 minutes) for consistent results, similar to preheating a conventional oven.
