Quick Scoop

350 °F in a fan (fan‑assisted) oven is about 160 °C (some guides round to 155 °C–165 °C).

Why the number is lower than a conventional oven

  • A standard (non‑fan) oven at 350 °F equals roughly 177 °C.
  • Fan ovens circulate hot air, cooking food faster and more evenly, so you reduce the temperature by ~20 °C (or 20–25 °F) to avoid over‑browning or drying out.

Practical tips when you set your fan oven to 160 °C

  1. Preheat for the full time the recipe states (fan ovens reach temperature quickly, but Alt: 10–15 min is usual).
  2. Check early —start testing at about two‑thirds of the original cooking time; many bakes finish 10–20 % sooner.
  1. Rotate trays halfway through if you’re cooking multiple sheets; even airflow can still create hot spots in some models.
  2. Watch colour – if the top browns too fast, loosely tent with foil.

A quick story from the forum

In a recent home‑baking thread, a user tried a classic vanilla‑cake recipe calling for 350 °F in a conventional oven. She set her new Fanoven to 177 °C (the straight conversion) and came back to a slightly domed, over‑crusted top while the centre was still gummy. She lowered it to 160 °C , reduced the time by 12 min, and the next batch was perfectly golden and moist—a perfect illustration of why the 20 °C drop matters.
