How Long to Cook an Ear of Corn in the Microwave?
The optimal microwave cooking time for an ear of corn, husked or unhusked, typically ranges from 3 to 5 minutes, depending on its size and the power of your microwave. For best results, cook one or two ears at a time.
The Quick and Easy Microwave Corn Revolution
Microwaving corn on the cob is a game-changer for busy weeknights and impromptu gatherings. It’s a method that delivers consistently tender, juicy corn with minimal fuss. Forget boiling huge pots of water or firing up the grill; with a microwave, you can have perfectly cooked corn in minutes. This guide will walk you through the process, debunk common myths, and answer all your burning questions about microwaving corn on the cob.
Benefits of Microwaving Corn
Microwaving corn offers several advantages:
- Speed: Significantly faster than boiling or grilling.
- Convenience: Requires minimal cleanup.
- Nutrient Retention: Studies suggest microwaving helps retain more vitamins compared to boiling.
- Flavor Enhancement: Some argue that microwaving concentrates the corn’s natural sweetness.
Step-by-Step Guide to Microwaving Corn
Whether you prefer cooking corn in its husk or without, the basic process remains simple.
Method 1: Cooking Corn in the Husk
- Preparation: Leave the husk intact. You can trim the silk that protrudes from the top if desired. Some people suggest soaking the entire ear in water for a few minutes before microwaving, but it’s generally unnecessary.
- Microwaving: Place the corn directly in the microwave. Cook for 3-5 minutes, depending on the size of the ear and the power of your microwave.
- Testing: Carefully remove the corn from the microwave. It will be hot! Let it cool for a minute or two.
- Shucking: Hold the top of the corn with a towel and carefully pull down the husk and silk. The silk should come off easily.
- Serving: Season with butter, salt, and pepper, or your favorite toppings.
Method 2: Cooking Corn without the Husk
- Preparation: Shuck the corn and remove all the silk. Rinse the corn under cold water.
- Microwaving: Wrap each ear of corn in a damp paper towel. Place in the microwave.
- Cooking Time: Cook for 2-4 minutes, depending on the size and microwave power.
- Testing: Carefully remove the corn. It will be very hot.
- Serving: Season as desired and enjoy.
Factors Affecting Cooking Time
Several factors influence the ideal cooking time:
- Size of the Ear: Larger ears require longer cooking times.
- Microwave Power: More powerful microwaves will cook corn faster.
- Number of Ears: Cooking multiple ears at once may require extending the cooking time.
- Freshness: Very fresh corn might cook slightly faster.
A good rule of thumb is to start with the lower end of the time range and add more time in 30-second increments if needed.
Troubleshooting and Common Mistakes
- Dry Corn: If the corn comes out dry, try wrapping it in a damp paper towel or leaving the husk on during cooking.
- Uneven Cooking: Rotate the corn halfway through the cooking time to ensure even heating.
- Burnt Corn: Reduce the cooking time if the corn is burning. Make sure the power level isn’t set too high.
- Tough Corn: If the corn is still tough after cooking, add another minute or two and check again.

Frequently Asked Questions (FAQs)
H4: Can I microwave frozen corn on the cob?
Yes, you can! However, you’ll need to increase the cooking time. A good starting point is 5-7 minutes, checking for doneness after 5. Frozen corn may require slightly longer cooking times, and it’s crucial to ensure it’s heated through.
H4: Is it safe to microwave corn in its husk?
Absolutely. In fact, many people prefer this method as it helps to retain moisture and enhance the flavor. Just ensure there are no metal staples or ties present on the husk.
H4: How do I know when the corn is done?
The best way to tell if the corn is done is to pierce a kernel with a fork. It should be tender and easily pierced. Be careful, as the corn will be very hot.
H4: Can I add butter before microwaving?
While you can add butter before microwaving, it’s generally recommended to add it after. Adding butter beforehand may affect the cooking time and result in unevenly flavored corn.
H4: Does microwaving corn remove nutrients?
Microwaving, in general, is less likely to degrade nutrients compared to boiling, which can leach nutrients into the water.
H4: Why does my corn sometimes explode in the microwave?
This is rare, but it can happen due to steam buildup inside the kernels. Puncturing the kernels with a fork before microwaving can help prevent explosions.
H4: How do I store leftover microwaved corn?
Wrap leftover corn tightly in plastic wrap or store it in an airtight container in the refrigerator. It’s best to consume it within 2-3 days.
H4: Can I microwave corn with the silk still on?
Yes, but it’s recommended to remove as much silk as possible before microwaving. The silk can become difficult to remove after cooking.
H4: What power level should I use on my microwave?
It’s best to use full power for microwaving corn. This ensures even and efficient cooking.
H4: Can I microwave multiple ears of corn at once?
Yes, but you may need to increase the cooking time by a minute or two. Be sure to check for doneness before serving.
H4: Does the type of corn (sweet corn, field corn) affect the cooking time?
Generally, the type of corn doesn’t significantly affect the cooking time. However, very mature field corn may require slightly longer cooking.
H4: Is it okay to microwave corn in a plastic bag?
No, it’s not recommended to microwave corn in a plastic bag unless it’s specifically labeled as microwave-safe. Otherwise, harmful chemicals may leach into the food. Use a damp paper towel instead.
