We can't be the only ones who get overly excited at the site of a mountain of freshly-picked corn cobs, in their gorgeous green-husked glory. It's a signal of late summer, a harbinger of holidays to come, and a highlight of our menu every year.  Since the peak season for sweet corn is fairly short (harvest generally takes place between mid-summer and November), we often buy a bounty and cook corn on the cob in big batches. What can we say, after long, frigid winters and rainy springs anticipating just this moment, it's tough to resist overdoing it!

Once you master how to reheat corn on the cob, you can feel free to overdo it any time. Simply refrigerate the cooled cooked corn in an airtight container for up to 5 days, then use one of our Test Kitchen's favorite methods for how to reheat corn on the cob below to bring each piece back to its butter-ready, warm, sweet glory.

Many of our favorite corn recipes can be made with either fresh or frozen corn kernels, so check your ingredient list; you might be fine to use your frozen kernels as-is. Or to reheat the frozen corn, transfer the corn kernels to a colander and rinse with cold water until the pieces no longer appear icy. In a skillet over medium-high heat, add corn and 1 to 2 tablespoons of butter. Cook, stirring frequently with a wooden spoon or heat-safe spatula, until the butter is melted and the corn is warm (about 5 minutes). Season as you see fit and dive in.
