Best Ways To Reheat Corn On The Cob
| Method | How to do it | Best for |
|---|---|---|
| Microwave | Cover with a little water and heat in short intervals | Fastest everyday reheating |

Microwave Method
- Place 1 or 2 ears in a microwave-safe dish.

How Long Leftover Corn Lasts
Cooked corn is a leftover once it has been boiled, grilled, roasted, or cut. Refrigerate it promptly in a covered container and use it within 3 to 4 days. Discard cooked corn that sat out overnight or has an unknown storage history.

- Reheat only the amount you plan to eat.
- Use 165 degrees F for reheated leftovers.
- Keep hot corn hot if it will sit on a buffet.
- Discard perishable food left out more than 2 hours, or 1 hour above 90 degrees F.
