Adjusted cook time

28 minutes

Formula

30 min × (350° ÷ 375°)

Notes

  • · This uses a simple inverse-proportion estimate. Always check food for doneness rather than relying on time alone — actual cooking times depend on the dish, oven, and altitude.

Cook Time Adjustment Calculator — How It Works

Cook Time Adjustment Calculator — How It Works

Adjusts cooking time when changing the oven temperature.

How it works

  1. Enter the original cook time, in minutes.
  2. Enter the original oven temperature.
  3. Enter the new oven temperature you want to use.
  4. The tool scales the cook time inversely with the temperature ratio to estimate the new cooking time.

Formula

Adjusted time = Original time × (Original temperature ÷ New temperature)

Example

A 30-minute bake at 350°F adjusted to 375°F gives an estimated 28 minutes.

Notes

This is a simple estimate based on a common rule of thumb — actual results depend on the dish, pan material, and oven. Always check food for doneness (internal temperature, color, texture) rather than relying on time alone.
