Freeze your corn in freezer-safe Ziploc bags. Quart bags are a good size. Measure as you fill the bag so you can mark the amount of corn on each bag along with the date.  Use a permanent marker like a Sharpie to label. Seal the bags leaving a small space open to help remove excess air. PRO-Tip: Insert a straw into that open part of the "zipper," and inhale to suck out any excess air. This will minimize frost build-up. Immediately seal once the air is removed. Frozen corn will be good for about 12 months. It's perfect for soups, casseroles, or just sauteed with some butter for dinner.
