How Long to Microwave 4 Ears of Corn? A Definitive Guide
Microwaving four ears of corn requires approximately 8-12 minutes, depending on the microwave wattage and whether the corn is husked or unhusked. For best results, add a small amount of water to the plate and rotate the corn halfway through cooking.
The Humble Ear: Why Microwave Corn on the Cob?
Microwaving corn on the cob is a quick, easy, and surprisingly effective way to cook this summer staple. It bypasses the need for boiling large pots of water or grilling with potentially uneven results. The microwave steams the corn inside its husk, retaining moisture and resulting in a tender, flavorful product. Even shucked corn benefits from the speed and convenience the microwave provides.
Benefits of Microwaving Corn
There are several advantages to choosing the microwave method:
- Speed: Significantly faster than boiling or grilling.
- Ease: Requires minimal preparation and cleanup.
- Flavor Retention: Steaming inside the husk helps retain the natural sweetness of the corn.
- Nutrient Preservation: Microwaving generally preserves more nutrients compared to boiling.
- Convenience: Ideal for a quick side dish or when time is limited.
Step-by-Step Guide to Microwaving 4 Ears of Corn
This guide covers both husked and unhusked methods for microwaving four ears of corn.
Method 1: Unhusked Corn
- Prepare the Corn: Leave the husks on. If desired, trim the silk protruding from the top, but avoid peeling back the husk.
- Moisten: Lightly dampen the husks under running water. This helps create steam.
- Arrange: Place the four ears on a microwave-safe plate.
- Microwave: Cook on high for 8-12 minutes. Start with 8 minutes and check for doneness. If not tender enough, microwave in 1-minute increments until cooked through.
- Cool: Let the corn cool slightly before removing the husks. The steam will help release the silk.
- Enjoy: Peel back the husks, remove the silk, and add butter, salt, and pepper to taste.
Method 2: Husked Corn
- Prepare the Corn: Remove the husks and silk from the corn.
- Moisten: Lightly rinse the corn under running water.
- Arrange: Place the four ears on a microwave-safe plate. Add 2-3 tablespoons of water to the plate. This helps create steam.
- Cover (Optional): Covering the plate with microwave-safe plastic wrap or a lid can help retain moisture. Poke a few holes to vent.
- Microwave: Cook on high for 6-10 minutes. Start with 6 minutes and check for doneness. If not tender enough, microwave in 1-minute increments until cooked through.
- Enjoy: Add butter, salt, and pepper to taste.
Factors Affecting Cooking Time
Several factors can influence how long it takes to microwave corn on the cob:
- Microwave Wattage: Higher wattage microwaves cook faster.
- Corn Size: Larger ears of corn require longer cooking times.
- Corn Freshness: Older corn may take slightly longer to cook.
- Unhusked vs. Husked: Unhusked corn generally takes longer due to the insulation provided by the husk.
- Initial Temperature: Corn that is colder (directly from the refrigerator) will require more time.
Common Mistakes and How to Avoid Them
- Overcooking: Overcooked corn can become tough and dry. Start with a shorter cooking time and check for doneness frequently.
- Undercooking: Undercooked corn will be tough and starchy. Microwave in additional 1-minute increments until tender.
- Insufficient Moisture: If microwaving husked corn, adding water to the plate is crucial for creating steam.
- Ignoring Rotation: Rotating the corn halfway through cooking helps ensure even cooking.
- Burning: If the husks become dry and start to burn, reduce the microwave power or shorten the cooking time.

Frequently Asked Questions (FAQs)
How can I tell if the corn is done?
Gently pierce a kernel with a fork. If it feels tender and releases milky juice, the corn is done. You can also squeeze the ear; it should feel slightly soft but not mushy.
Is it safe to microwave corn in the husk?
Yes, it is perfectly safe to microwave corn in the husk. In fact, many prefer this method as it helps retain moisture and enhances flavor. Ensure the husks are slightly damp before microwaving.
Can I microwave corn with the silk still on?
Yes, but it’s generally easier to remove the silk after microwaving. The steam helps loosen the silk, making it easier to pull away.
What’s the best way to add flavor to microwaved corn?
Classic additions like butter, salt, and pepper are always a good choice. For more adventurous flavors, try chili powder, lime juice, Parmesan cheese, or a sprinkle of smoked paprika. Experiment with different seasonings to find your favorite combination.
Can I microwave frozen corn on the cob?
Yes, but it will require a longer cooking time. Add a few extra minutes and check for doneness. Thawing the corn slightly beforehand can help reduce cooking time. For four ears of frozen corn, expect to add approximately 3-5 minutes to the unhusked times.
How long does microwaved corn last in the refrigerator?
Cooked corn on the cob can be stored in the refrigerator for up to 3-5 days. Allow it to cool completely before storing it in an airtight container.
Can I reheat microwaved corn?
Yes, you can reheat microwaved corn in the microwave. Wrap the corn in a damp paper towel to help retain moisture and microwave for 1-2 minutes.
Does microwaving corn affect its nutritional value?
Microwaving generally preserves more nutrients than boiling. Some water-soluble vitamins may be lost, but the overall nutritional impact is minimal. Nutrient loss is less than other cooking methods.
Why does my corn sometimes turn out rubbery in the microwave?
This is usually due to overcooking. Start with a shorter cooking time and check for doneness frequently. Overcooked corn loses its moisture and becomes tough.
Can I use microwave popcorn bags to cook corn on the cob?
No, microwave popcorn bags are designed specifically for popcorn and are not suitable for cooking corn on the cob. They can create excessive steam and potentially cause the bag to burst. Use a microwave-safe plate.
What microwave setting should I use to cook corn?
Always use the high power setting when microwaving corn on the cob. Lower power settings will result in uneven cooking and a longer cooking time.
Is it better to microwave corn with or without butter/salt?
It’s generally best to add butter and salt after microwaving. Adding them before can result in uneven distribution and may affect the cooking process. This way, you also maintain better control over the amount of each ingredient.
