This tool converts conventional oven cooking time to microwave cooking times.
Enter the oven cooking time in the tool below. A conversion factor of 4 is used as default value.
The conversion factor depends on your microwave’s power. Here’s a general guide:
- 1000 watts or higher: Use a conversion factor of 4 (1/4th of the oven time)
- 800-1000 watts: Use a conversion factor of 3.5
- 600-800 watts: Use a conversion factor of 3
Background
Converting oven cooking times to microwave cooking times requires understanding the differences in how these appliances cook food. Here’s a step-by-step guide to help you make these conversions effectively:
1. Understand the Basics
- Oven Cooking: Uses dry heat, typically with temperatures ranging from 250°F to 500°F (120°C to 260°C). Cooking times are generally longer due to slower heat penetration.
- Microwave Cooking: Uses microwave radiation to heat water molecules within food, resulting in faster cooking times. Power levels in microwaves are usually measured in watts, ranging from 600 to 1200 watts.
2. Determine the Oven Cooking Time and Temperature
Start with the original recipe’s cooking time and temperature. For example, if the recipe requires baking a dish at 350°F for 60 minutes, note these details.
3. Adjust for Microwave Power
Microwave ovens cook food much faster than conventional ovens. A rough guideline is that food cooked in a microwave requires approximately one-quarter of the time it would in an oven. However, this can vary based on the microwave’s wattage.
4. Use a Conversion Formula
A general formula for converting oven time to microwave time is:
Microwave Time (minutes)= Oven Time (minutes) / 4
For example, if your oven recipe takes 60 minutes at 350°F and your microwave is 800 watts:
Microwave Time = 60/4 = 18.75 minutes
Use the calculator on this page to find this time. You can vary the conversion factor depending on the wattage of your microwave.
5. Consider Food Type and Density
- Dense Foods: Foods like meat or casseroles might need longer than the calculated time. You might start with the calculated time and add 1-2 minutes as needed.
- Light Foods: Foods like vegetables or rice may need less than the calculated time. Start checking them a couple of minutes before the calculated time.
6. Use Microwave-Safe Cookware
Ensure you’re using microwave-safe dishes. Some materials can affect cooking times and the evenness of cooking.
7. Stir and Rotate
Microwave cooking can sometimes result in uneven heating. Stir or rotate the food halfway through the cooking time to ensure even cooking.
8. Start with Lower Power Levels
If your microwave has adjustable power levels, consider starting at 70-80% power to avoid overcooking or drying out the food. You can always increase the power if needed.
9. Check for Doneness
Microwaves don’t brown food, so use other indicators to check for doneness. Use a food thermometer for meats or check the texture and consistency for other dishes.
10. Allow for Standing Time
Microwave cooking often continues even after the microwave stops. Let your food stand for a few minutes after cooking to allow the heat to distribute evenly.
Example Conversion
Oven Recipe: Baked Vegetables at 375°F for 60 minutes.
Microwave Conversion:
- Start with the formula:
Microwave Time= 60/4 = 18.75 minutes - Adjust for food type: Some vegetables can be dense, add a couple of minutes: 20-22 minutes at 70-80% power.
- Use a microwave-safe dish and rotate halfway through cooking.
- Check the internal temperature with a meat thermometer to ensure it reaches 165°F (74°C).
