Calibrating Your Home Oven
Most home ovens fluctuate as they cycle, and many run anywhere from 10 to 30 degrees off their set point. A single thermometer tells you exactly where your heat lives, removing the guesswork from your timer.
A cold oven is a blank slate.
Start this process with a completely cold oven to get an accurate read on how long it takes to reach temperature and how it stabilizes.

The Dead Center Rule
Place your thermometer on the center rack, halfway between the front and back of the oven, to capture the temperature where most of your baking happens.
The method.
Position the thermometer.
Set your thermometer on the middle rack. If it has a hook, hang it from the center of the rack wire so it sits clear of the oven walls.
Set the dial.
Turn your oven to 350°F. Do not rely on the preheat indicator light, as the air temperature often fluctuates significantly in the first ten minutes.
Wait for stabilization.
Let the oven run for at least 20 minutes once the preheat signal sounds. This allows the internal components and the air to reach a steady state.
Read and record.
Check the thermometer through the oven window. If the oven is set to 350°F but the thermometer reads 335°F, your oven runs 15 degrees cool.
When it doesn't go to plan.
Check your oven's temperature in different locations; the back is often hotter than the front.
If your oven has an electronic control panel, look for an 'offset' or 'calibration' mode in the manual to shift the internal reading by the number of degrees you found.
If your oven is analog, keep a sticky note on the side with the offset (e.g., 'Set to 365 for 350') to account for the consistent variance.
The ones that keep coming up.
How often should I recalibrate?
Once every six months or whenever you notice browning patterns on your food becoming uneven.
