Microwave Corn on the cob in a Pyrex dish

To microwave corn on the cob in a pyrex dish, place the ears of corn in the dish, sprinkle your favorite seasonings, add 2-3 tbsp of water, cover the dish with a microwave-safe lid or paper towel then nuke at 70% power for about 5-7 minutes or according to the microwave’s instructions.

Microwave ovens have different power levels, so getting it exactly right might take some time. If you’re using a lower-wattage microwave (less than 1000 watts), you may cook the corn in the Pyrex on high. You may even get away with microwaving it for a longer period because the corn will not be done.

If your microwave has a wattage above 1000 watts, you may need to cook the corn at 50-70% power to prevent it from overcooking or heating the dish too quickly.

I used a microwave with 1000 watts and cooked it on 70% power for 7 minutes.

Is it Safe to Microwave Corn in a Pyrex Dish?

Yes, it is safe to microwave corn in a Pyrex dish as long as you microwave it correctly. Pyrex dishes are made from glass, so microwaving can cause them to shatter if it is heated too quickly or for too long then cooled. But it is completely safe if you do it right and microwave it for the right amount of time.

Microwaves almost instantly heat up whatever you put in them, and the longer it stays there, the hotter it will become. So when you put a pyrex dish in the microwave, it will heat up quickly, and the longer you leave it there, the hotter it will get.

That’s why the recommendation is to only nuke the corn in a pyrex dish for about 5-7 minutes at a time. After the first run, check the corn to see if it is done. If it isn’t, you can run it again in 2-minute intervals. You should also reduce the power setting of your microwave if you own one that is above 1000 watts.

Another point that can affect the safety of microwaving a pyrex dish is if you let it cool too quickly after it has been heated. To prevent this from happening, you simply need to avoid taking the dish out of the microwave while it is still hot. Doing so will allow the corn more time to cook and also ensure that the dish doesn’t shatter.

How long do you microwave corn on the cob in a pyrex dish?

You microwave corn on the cob in a pyrex dish for 5-7 minutes at a time, depending on the microwave’s power level. You can microwave it for 2-minute intervals if it’s not done after the first run.

How do you know when the corn is done?

One way to know when the corn is done is to pierce it with a fork. If the fork goes in easily, then the corn is done. Another way to tell if the corn is done is to see if the kernels are soft and plump. If they are, then the corn is ready. You can also taste a kernel to see if it’s cooked through.

If you note the color of the corn before putting it in, you may also notice that it takes on a richer yellow when it is done. Or you could even use a food thermometer to test if the corn’s internal temperature gets to 165 degrees F.


So, if you’re looking for an easy way to microwave corn on the cob, then using a Pyrex dish is definitely the way to go. Just be sure to follow the cooking instructions closely so that you don’t end up with a mess in your microwave! And once you’ve mastered this method, feel free to get creative and add your own seasonings – I’m sure your family will love it.
