For a first try, set the air fryer 25°F below the oven recipe’s temperature and plan to cook for about 20% less time. Treat both changes as starting estimates: check the food early and add time if needed, since results vary by recipe and air-fryer model.
Use this starting conversion
Whirlpool’s general air-fryer baking guidance is to lower the recipe temperature by 25°F and reduce the cooking time by 20%. The page does not state a publication year, and the guidance is a rule of thumb—not a guaranteed conversion for every food or appliance. Whirlpool’s air-frying and baking guidance also cautions that instructions may vary by air-fryer model.
- Lower the oven temperature by 25°F. For example, if the recipe calls for 400°F, begin at 375°F.
- Estimate 80% of the recipe’s cooking time. A 20-minute oven time gives an initial check at about 16 minutes. That is a calculation from the 20% reduction, not a tested result for a particular recipe.
- Check before the estimated time is up. Look for browning and doneness, then continue in short increments if the food needs longer.
Why the result can differ
An air fryer circulates heated air in a compact cooking space. Whirlpool describes air-fryer baking as generally faster than conventional oven cooking, but the outcome depends on the recipe, batch size, food arrangement, and appliance model. Follow the manual for your air fryer when it gives model-specific instructions.
Convection guidance offers context, not a guarantee of identical results. GE Appliances recommends lowering the temperature by 25°F for convection baking (GE Appliances’ convection guidance). LG also gives a 25°F reduction for certain convection modes; its page was published about four months before October 7, 2026, though the exact date was not stated in the search result (LG’s convection cooking tips). These oven rules do not establish that a full-size convection oven and a countertop air fryer cook the same way.

Adjust for the food and the appliance
- Account for the batch. Air fryers are generally used for smaller, quicker batches, while convection ovens can cook more slowly and gently, according to Samsung’s broad comparison. These are general descriptions, not performance guarantees for every model (Samsung’s air fryer and convection oven comparison).
- Use the manual’s directions. Model-specific guidance takes precedence over a generic starting adjustment.
- For meat and poultry, verify safety separately. Use applicable food-safety guidance and the product’s instructions; the guidance cited here does not establish safe internal-temperature targets.
What to remember
Start 25°F lower and check at roughly 80% of the oven recipe’s stated time. Then judge the food, not the arithmetic: adjust in short increments and use the appliance manual and relevant food-safety guidance where applicable.
