How to Reheat Corn on the Cob in a Microwave – Everything you Need to Know

There are a lot of methods for cooking corn on the cob. Some people boil it, some grill it over an open flame, and others steam or bake it. Recently though, a new method has been gaining popularity: microwaving your corn on the cob! In this blog post, we’ll answer the top questions that will help you get started with re-heating your corn in the microwave.

Can you reheat corn on the cob in the microwave?

Yes, you can reheat corn on the cob in a microwave. Using a microwave is a good way to reheat corn on the cob because it will not dry out or burn it. Furthermore, reheating using a microwave also allows you to preserve the flavor and quality of the corn.

However, you can also reheat it on a stovetop if desired.

But doing so will most likely get rid of some of the flavor and quality.

That’s reheating corn in a microwave is the best option when you need to reheat it quickly and preserve the flavor. Or possibly if you don’t have access to a stovetop.

Is corn on the cob good reheated?

Corn on the cob typically tastes great after being reheated. However, depending on the method of reheating there might be a slightly different texture than if you were to eat the corn right after being cooked.

Specifically, microwaving or reheating corn on the cob can result in soft and soggy kernels instead of crisp ones like they would be when first prepared. Other methods of reheating also produce their own set of issues that can change the taste of your reheated corn.

For instance, reheating in the oven can cause the corn to become tough and dry. While boiling can also cause it to become soggy and lose all flavor.

That’s why some people might not enjoy reheated corn on the cob.

But, if you don’t mind a slight change in texture and you follow the instructions to reheat it properly then reheating is fine and will not ruin the taste of corn.

How long do you microwave leftover corn on the cob?


Corn on the cob is pretty easy to reheat in a microwave. All you need to do is place ears of corn on a microwave-safe plate, rub some butter over it with a little seasoning, cover it, and heat them for about 10-20 seconds in intervals. After about 1-2 minutes of heating, the corns should be properly reheated.

Reheating your corn in intervals will ensure that the corn heats evenly inside and outside without turning into popcorn because of overheating.

What happens if you reheat corn too long?

The consequences of reheating your corn on the cob in a microwave for too long will be slightly different than what might happen when re-heating its stovetop.

The kernels will start to lose their moisture, and turn into popcorn because they’re overcooked. This is due to the high temperatures microwaves produce that cook food more quickly than other methods.

Microwave ovens typically heat up food in less time than an open flame or boiling water, so this method can cook them way faster and make them lose most of their deliciousness fast!

However, there is no set duration for how long you should microwave your leftover corn on the cob before it turns into popcorn. Simply because it depends on the power of your microwave, and how long you reheat it. That’s why the best recommendation is to reheat in intervals until it’s heated all the way through.

How do you reheat corn on the cob without a microwave?

There are three methods of reheating corn on the cob without a microwave:

  • Reheating in an oven
  • Reheat by boiling it for five to ten minutes
  • Reheating it using a grill

Reheating in an oven

Reheating corn on the cob in an oven will give you a crispy and delicious result.

  1. The first step is to preheat the oven to 400 degrees F.
  2. Take baking pan or dish and add 2 tablespoons of water to the pan.
  3. Put the cooked ears of corn in a greased cookie sheet or roasting pan and cover it with aluminum foil.
  4. Reheat in an oven for 5 minutes at 400 degrees F
  5. Remove when heated through then rub butter over the corn and add seasonings such as salt and pepper before serving.

Reheat by boiling

Corn on the cob is a popular dish that tastes wonderful, but it can be hard to reheat if you don’t have access to an oven.

One option for reheating corn without an oven is boiling it in water. This method works best when you’re short on time or if you don’t want to deal with the extra hassle of reheating in an oven.

However, there are some cons that come with this method as well. For example, the corn can become soggy and lose its flavor when boiled for too long. But if you follow these instructions then re-heating your leftover corns by boiling should work just fine!

To reheat by boiling:

  1. Set a large pot of water on the stove and bring it to a boil.
  2. Add your corn to the boiling water and let it cook for about 2 minutes.
  3. Remove the corn after the 2 minute time period and slather them with butter and salt.

If you reheat it for any longer than 2 minutes you may end up spoiling the corn.

Reheat using a grill

If you have access to a barbecue or outdoor grill then this is the best way for reheating your leftover corn on the cob.

One of the main benefits that come with re-heating your corns over an open flame such as a barbeque pit is that it helps add more flavor and crispness back into them! This method also requires minimal preparation, so if time isn’t really something you’re worried about since you may be grilling other tasty dishes then here are step by step instructions:

  1. Take your corn ears and coat generously with butter and seasonings like salt and pepper.
  2. Wrap ears tightly in foil.
  3. Arrange directly on the grill burner and rotate for about 30 seconds on each side.
  4. After about 2 full rotations the corn cobs will be heated and ready to serve.

How Long Does Corn on the Cob Last Unrefrigerated?

Now let’s say you’re not planning on eating all your corn right away and you want to store the leftover corn in the fridge. How long will it last?

This is a good question and there’s no one answer that can perfectly describe how long your corns should last unrefrigerated because it all depends on several factors and storage conditions.

But here are some guidelines:

If stored properly, fresh ears of sweetcorn may be kept for up to three days – if they were refrigerated immediately after cooking or purchasing them from a market or farm stand. If not refrigerated you should try to consume them within 2 hours because after that they’ll start losing a lot of their sugars.

So you must keep them at temperatures below 40 degrees F if you want them to last a longer time.

Wrapping Up

Reheating corn on the cob with a microwave is the best method when you’re in a rush or if you don’t have access to any other cooking appliances.

Reheating corn is generally a good idea, but it can cause it to lose flavor. There are different ways to reheat it and the method you choose is really just up to your preferences. However, we can testify that microwaving is by far the quickest and most efficient way to reheat your corns!

So what are you waiting for? Reheat those sweet, delicious ears of corn and let us know how it turned out.
