How to Heat Frozen Corn on the Cob

Nothing says summer quite like a grill lined with juicy, buttery corn on the cob. Since it is such a popular side dish, it makes sense to whip up a few extras to have for later. Plus, you can store corn on the cob in the freezer, which means you’ll have leftovers to reheat at a moment's notice. With that in mind, it might be helpful to know some of the best ways to heat frozen corn on the cob.

Frozen Corn on the Cob

If you want corn on the cob that doesn’t taste frozen, then knowing the best way to prep, pack and store frozen corn on the cob makes a huge difference.

To freeze corn on the cob, make sure it is cool or at room temperature. Next, wrap each cob in plastic wrap and place it in a freezer-safe Ziploc bag. For extra protection from freezer burn, place the bags in freezer-safe plastic containers. Don’t forget to label them with the date before putting them in the freezer.

When it comes time to eat your frozen corn on the cob, you will need to decide if you’re going to put the corn in the fridge overnight to defrost it or cook frozen corn on the cob right from the freezer. Tossing them in the fridge the night before reduces the cooking time for the oven, microwave, grill or stove top.

Heating in the Oven

While most people will develop their favorite method to cook corn on the cob, there are a few worth pointing out, especially when it comes to heating frozen corn on the cob.

Cooking frozen corn in the oven with foil will take the most amount of time, but it’s also one of the easiest methods because you can put it in the oven and do something else until the timer goes off.

  •  Heat the oven to 425 degrees Fahrenheit.

  • Mix together milk and melted butter and rub or brush it on each frozen corn cob. This will result in delicious corn on the cob with milk.

  • Wrap each cob in aluminum foil.

  • Place a cookie sheet on the lower rack of the oven. Then, line the corn on the cob on the upper rack of the oven. Bake for 25 to 35 minutes until thoroughly cooked.

To add flavor, season with spices, herbs, salt and, of course, butter.

Heating in the Microwave

While the microwave is definitely the quickest way to heat frozen corn on the cob, it’s oftentimes not the best when it comes to taste. To microwave corn on the cob without the husk, you’ll want to first rinse the corn under cold water.

  • Add water to a microwave-safe bowl. Make sure not to fill it too high. You don’t want the water to overflow when you put the corn in the bowl.

  • Microwave on high for seven or eight minutes. This will heat four corn cobs.

  • Check to see if the frozen corn on the cob is thoroughly heated before serving.

  • Add butter and seasoning. 

Heating on the Stove Top

The stove-top method may take longer than the microwave, but the results are definitely worth the extra time. Plus, you can keep your eye on the pot while the corn is boiling.

  • Fill a large pot with cold water.

  • Place the frozen corn on the cob in the pot.

  • Set the heat to high. After the water starts to boil, cook for another five to eight minutes.

  • Turn the stove top off and remove the pot. Take the corn out and put it on a plate.
