Do I need a Stronger Microwave in my HIGH ALTITUDE Kitchen?

Updated: May 9, 2023


Microwave cooking can be a bit tricky in a high altitude kitchen because the cooking time and power settings may need to be adjusted. Here are some tips to help you with microwave cooking in a high altitude kitchen:

  1. Reduce cooking time: In general, you should reduce the cooking time by about 5-10% for every 1,000 feet above sea level. For example, if a recipe calls for 1 minute of cooking time at sea level, you would reduce the cooking time to about 45-55 seconds at an altitude of 5,000 feet.

  2. Adjust power settings: In addition to reducing cooking time, you may need to adjust the power settings on your microwave. In general, you should reduce the power level by about 10-15% for every 1,000 feet above sea level. So, if a recipe calls for cooking on high power at sea level, you would reduce the power level to about 85-90% at an altitude of 5,000 feet.

  3. Use a microwave-safe dish: Make sure to use a dish that is microwave-safe and appropriate for the food you are cooking. Some dishes may not be able to handle the high heat of a microwave, which could cause them to crack or break.

  4. Stir frequently: When cooking in a microwave, it's important to stir the food frequently to ensure even cooking. This is especially important at high altitudes where the cooking time and power settings may need to be adjusted.

  5. Be cautious with liquids: Liquids can boil over quickly in a microwave, so be cautious when heating them. Use a microwave-safe container with a lid or cover the container with a microwave-safe lid or plastic wrap to prevent splatters.

When cooking in a microwave, it's important to follow the manufacturer's instructions and to use caution when handling hot dishes. Additionally, be aware that microwave cooking may not always produce the same results as traditional cooking methods, so it may take some trial and error to get the cooking time and power settings right for your specific microwave and altitude.


Ensuring the accuracy of your oven's temperature is critical.. To achieve this, it's advisable to use an oven thermometer https://amzn.to/430XXR2 . Additionally, it's essential to check the temperature of the cake, bread, or meats you're baking or cooking with an internal thermometer. As a result, I recommend investing in a thermometer to monitor your cooking and baking accurately. Don't procrastinate as your next cake or dish may rely on it.
