Time as well as temperature
After lowering the temperature by 20°C, food usually still cooks a little faster in a fan oven. Start checking about 10 minutes before the recipe says, especially for cakes and biscuits.
When not to use the fan
Rich fruit cakes, meringues and some slow-cooked dishes do better without the fan, as the moving air dries the surface.
Questions and answers
Questions about fan oven conversions
How much lower should a fan oven be set than a conventional one?
Enter the conventional temperature in the calculator above for the fan equivalent. As a rule of thumb, fan ovens are set roughly 20°C lower than a conventional recipe temperature.
Does a fan oven cook food faster as well as at a lower temperature?
Yes, the moving air still speeds up cooking even after the temperature is lowered, so start checking food a little earlier than the recipe's stated time, particularly for cakes and biscuits.
Are there dishes that shouldn't go in with the fan on?
Rich fruit cakes, meringues and some slow-cooked dishes can dry out or crust unevenly under moving air, so many cooks turn the fan off for these even if the oven defaults to it.
