Let’s get started.

Can You Cook Corn on the Cob in the Microwave

Yes, you can cook corn on the cob in the microwave. However, there are a few important things to consider before proceeding.

How to Cook Corn on the Cob in the MicrowaveCorn is a popular vegetable that is often served as an accompaniment to many meals. It’s also one of those vegetables that you can prepare in various ways, such as boiling or steaming. Initially cultivated by Native Americans, it has been used by humans for thousands of years and is now grown worldwide.

Due to its popularity, it’s not surprising that there are many different ways of cooking it. However, one of the most popular methods is by microwaving. It’s quick and easy, and no special equipment is required. In fact, all you need is a microwave-safe dish and a few minutes of your time.

So, why are there reservations about cooking corn in a microwave?

  • First, microwaves have a reputation for cooking food unevenly. This is especially true for vegetables and other foods that are not dense enough to absorb microwaves efficiently. As such, there’s always a risk of undercooking or overcooking your corn when using a microwave.


  • Second, many people believe that microwaving changes food structure and makes it less nutritious. However, studies have shown that in most cases, microwaving does not affect nutrient content. In fact, microwaving foods may retain more nutrients than other preparation methods.


So, does that mean you should stop worrying about microwaving your corn?

Well, yes and no. Yes, because as long as you follow a few simple guidelines mentioned below, there’s nothing wrong with microwaving corn on the cob. No, because while it’s perfectly safe to cook corn in a microwave, it’s not better than other methods.


How Long Should You Put an Ear of Corn in the Microwave?

It will take between 1 and 4 minutes for an ear of corn to cook in a microwave on high. If you want it extra-crispy, you can try cooking it for longer, but don’t overcook it.

This, however, is only a rough estimate. The time it takes to cook an ear of corn in a microwave depends on its size and weight and your microwave’s wattage. For example, if you have a high-wattage microwave, you might need to set it for less time than someone with a lower-wattage one.

Burnt corn is no fun and will leave you with an unpleasant aftertaste. Your best bet is to add two minutes for every ear of corn you’re cooking. This way, you’re sure not to overcook it. If your microwave has a turntable, rotate it halfway through cooking time. There is also a possibility of reheating corn on cob.

So, how do you tell when an ear of corn is done?

You can tell when an ear of corn is done by squeezing its thickest part between your thumb and forefinger. The kernels should be soft but firm enough not to fall off easily. If it’s still uncooked, give it a few more minutes in the microwave.


Tips for Cooking Corn on the Cob in the Microwave

Cooking corn can be a pain at times. But if want a juicy, tender ear of corn, you’ll need to understand a few basics. So here are some tips for cooking corn in your microwave.


  • Choose fresh ears that are heavy for their size and have husks that are tight and green (not dried out or brown). The kernels should be plump and full, not shrivelled or dull in colour. If you’re using frozen corn, make sure it’s completely thawed before cooking.


  • Do not remove husks from your corn. The husk traps steam, which helps cook and tenderize your corn. If you have already shucked ears of corn from the store, wrap them in a damp paper towel. This will keep them moist while microwaving.


  • Remove the silk from your corn before cooking. You don’t want any strands getting stuck in your teeth. Simply pull it gently off with your fingers or a pair of kitchen shears, taking care not to tear any kernels.


  • Make sure to use a microwave-safe dish when cooking your corn. Avoid plastic, as it can melt or warp in high heat. Glass and ceramic are best for microwaving since they won’t leach chemicals into your corn.


  • Microwaving more than two ears of corn at once can result in uneven cooking and steam burns. Instead, cook in batches or use multiple dishes for your corn. Nevertheless, if you microwave several ears of corn at once, arrange them in a single layer with space between them.


  • You’ll want to cook your corn for about three minutes per ear or until tender when pierced with a fork or knife. The kernels should be soft and juicy, not crunchy or stiff.


  • Use potholder or oven mitts when removing your corn from a microwave, as it will be hot and steamy. Let it cool for a few minutes before serving to allow any residual heat to dissipate.


  • Leftover cooked corn can be refrigerated in an airtight container for three days.


How to Cook Corn on the Cob in the Microwave

The method for cooking corn in a microwave depends on its state. If you’re using already shucked ears of corn, the process will differ from that of fresh, unshucked corn on the cob.

We’ll show you how to cook it both ways to get consistent results.


Method 1


The following instructions detail how to cook corn cobs in a microwave without removing their husks.


  1. Place an unshucked ear of corn vertically (or horizontally) on a microwave-safe plate. If you’re cooking several ears, space them out, so they aren’t touching one another.


  1. Leave it uncovered and cook for about 3 minutes on high, rotating once halfway through cooking time. The corn is done when you can easily pierce a kernel with a fork or knife. If not, continue cooking in 30-second increments until done.


  1. Using potholder or oven mitts, remove your corn from the microwave and let it cool for a few minutes before serving.


  1. Slide off the corn from the husk and cut off the stem end. If there are any traces of silk, remove them with a stiff brush or your fingers.


  1. Serve with butter, salt, pepper, or any other seasonings.

Method 2

If you’re using fresh, unshucked ears of corn, follow these steps:


  1. Wrap your ear of corn in a damp paper towel and place it on a microwave-safe plate. This will keep your corn from drying out while cooking.


  1. Place the plate in your microwave and cook for 3 minutes on high. Cooking in a high setting will ensure that all sides of your corn are cooked evenly.


  1. Rotate once halfway through cooking time, then check for doneness by piercing a kernel with a fork or knife. It’s done when it’s easily pierced. If not, continue cooking in 30-second increments until done.


  1. Using potholders or oven mitts, remove your corn from the microwave as it will be hot.


  1. Allow it to cool for a few minutes so the heat can dissipate and you can handle it safely.


  1. Slice off each end of each ear with a sharp knife. This will make it easier to remove all kernels from your ears if you want to use them in another recipe.


  1. Rub your corn down with butter and seasonings and enjoy.

In these cases, a microwave provides a convenient solution. Cooking will take about three minutes per ear of corn. The good news is that, if done correctly, microwaving retains all of the nutrients.

So, don’t wait until summer to enjoy a tasty ear of corn. With a bit of planning and preparation, you can enjoy it anytime.
