Professional Baking Tips for Fan Ovens
1. Oven Thermometer is Essential
Most ovens run hot or cold. For precision baking, place an independent oven thermometer in the center of your oven to verify actual temperature.
2. Adjust Baking Times
As a general rule, reduce baking times by 10-15% when using fan mode. Start checking for doneness earlier than recipe suggests.
3. Rack Position Matters
Middle rack works best for most baking. For multiple racks, rotate pans halfway through baking for even results.
4. Avoid Overcrowding
Fan ovens need good air circulation. Leave at least 2 inches between pans and avoid covering oven racks with foil.
5. Humidity Control
Fan ovens can dry foods faster. For moist cakes, place a pan of water in the bottom of the oven during baking.
6. High Altitude Adjustments
At elevations above 900m (3000ft), you may need additional temperature reductions of 5-10°C in fan ovens.
Fan Oven Conversion FAQs
Why do fan ovens need lower temperatures?
Fan ovens circulate hot air continuously, creating more efficient heat transfer to your food. The 20°C reduction compensates for this increased efficiency, preventing overcooking or burning.
How do I know if my fan oven runs hot or cold?
Place an oven thermometer in the center of your oven. Set to 180°C fan and let preheat for 20 minutes. Check thermometer reading through the window. If it's more than 10°C different, you may need to adjust your settings.
Should I reduce both temperature and time?
Yes, for most recipes you should reduce temperature by 20°C (from conventional to fan) and reduce time by 10-15% (start checking early).
Are all fan ovens the same?
While the 20°C rule works for most fan ovens, there can be variations. Standard fan ovens typically need -20°C adjustment, while multi-function/combi ovens may need -10 to -30°C adjustments.
What is 425°F in a fan oven?
425°F converts to approximately 220°C in a conventional oven. For a fan oven, reduce by 20°C to get 200°C.
How to convert gas mark to fan oven?
Use our conversion chart above. Generally, gas mark 4 = 180°C fan, gas mark 6 = 200°C fan, and gas mark 2 = 150°C fan.
Fan ovens circulate hot air continuously, creating more efficient heat transfer to your food. This means:
- Heat reaches all surfaces of the food more evenly
- No cold spots in the oven cavity
- Faster cooking times overall
The 20°C reduction compensates for this increased efficiency, preventing overcooking or burning.
Follow this simple test:
- Place an oven thermometer in the center of your oven
- Set to 180°C fan and let preheat for 20 minutes
- Check thermometer reading through the window
If it's more than 10°C different from set temperature, you may need to adjust your settings or have your oven calibrated.
Yes, for most recipes you should:
- Reduce temperature by 20°C (from conventional to fan)
- Reduce time by 10-15% (start checking early)
However, some delicate items like soufflés or custards may only need temperature adjustment. Experience will help you judge best.
While the 20°C rule works for most fan ovens, there can be variations:
| Oven Type | Typical Adjustment |
|---|---|
| Standard fan oven | -20°C |
| Multi-function/combi ovens | -10 to -30°C (check manual) |
| Professional convection ovens | -25 to -30°C |
Always consult your oven's manual for specific recommendations.
