How long do you cook something at 375°F in an air fryer instead of the oven?

Reduce the oven time by roughly 20%. A 30-minute bake becomes 23 to 26 minutes, a 45-minute bake becomes 34 to 38 minutes. Check at 75% of the adjusted time. University of Illinois Extension states the rule as "reduce temperature by 25 to 30°F and reduce cooking time by 20%".

What is 375°F in Celsius for an air fryer?

375°F is about 190°C as an oven setting. The air fryer equivalent is 175°C — a 15°C reduction, not a converted 13.9°C, because air fryer dials are marked in steps of 5 and 10.

375°F in the oven is 350°F in an air fryer

375°F in a conventional oven is about 350°F in an air fryer — reduce the temperature by 25°F and the time by roughly 20%. A 30-minute oven bake at 375°F becomes 23 to 26 minutes at 350°F, checked at 18 minutes. In Celsius that is 190°C down to 175°C.

What to watch at 375°F

A workhorse setting for roasting vegetables and cooking fish. Converting down to 350°F puts you squarely inside the 350–400°F band the USDA describes as typical for air frying, which is a good sign the conversion is landing somewhere sensible rather than at an edge of the machine’s range.

Overcrowding the appliance can prevent enough air circulation to properly cook the food. — USDA Food Safety and Inspection Service.

Sources for the rule itself, including why it is a range rather than a single figure, are on the converter page. In short: no manufacturer or food agency publishes a conversion formula, and the most authoritative statement of it — University of Illinois Extension — says “reduce temperature by 25 to 30°F and reduce cooking time by 20%”.
