How it works
Moving air can cook food more evenly and promote browning, often at a lower temperature or in less time. Pan placement and crowded racks still affect circulation.
What people often miss
Not every recipe benefits equally. Delicate batters may set differently, and oven designs vary, so manufacturer guidance and early checking are useful.
Why this question comes up
The fan symbol on an oven can change familiar baking times enough to surprise new users.
Key points
- A convection oven uses a fan to circulate hot air, while a conventional oven relies mainly on heat rising and natural air movement.
