Test Your Oven Temperature

Test Your Oven Temperature

Obviously the easiest way to do this is using a thermometer – but if you don’t have one you can still get a good idea of how accurate your oven temperature really is.

You will need:

  • Oven
  • Tray
  • Aluminium Foil
  • Sugar


  1. Set your oven to 175°C (350°F) and let it heat up for 15 minutes.
  2. Place a tablespoon of sugar on a piece of foil and place it on a tray in the centre of the oven.
  3. Check after 15-20 minutes. If the sugar has melted, then your oven is running hot.
  4. If the sugar hasn’t melted, increase the temperature to 190°C (375°F) and repeat steps 2-3. The sugar should be completely melted. If it doesn’t, your oven is running cold.

If your oven is running hot or cold, you can start at a lower temperature and raise the temperature 5°C/10°F every 15 minutes until it melts.  Table sugar melts at 186°C (367°F), so once it melts, your oven is at least that hot.

Keep in mind that ovens also don’t heat up in straight lines, they tend to overshoot and even vary by several degrees while cooking, so if you really want to know – get yourself a thermometer.
