Canning corn is a great way to preserve your harvest. Some people love it, and some don’t. Personally, I like the flavor of home-canned corn too. Canning corn from your own garden or another local grower is still better than store-bought canned sweet corn.
Many people also prefer the taste of frozen corn. For these reasons, freezing corn is another great preserving option. I do some of each because my family prefers the frozen over canned. But I love the convenience of canned!
We have a wonderful variety of sweet corn that is grown around here called Olathe Sweet Corn. It is so good and sweet, and they have a festival weekend dedicated to corn. The weekend includes concerts and all-you-can-eat corn on the cob.
You can freeze canned corn, but you cannot freeze corn in a can. Drain all the water from the corn and freeze it in the freezer bag before storing it in the freezer.

Cutting Corn Off the Cobs
Cut the kernels from the cob. This can get messy since the corn tends to squirt. Do it in an area that will be easy to clean up. I have a big island in the center of my kitchen that I use. I LOVE easy clean up! Outside is another great choice. We have an outdoor kitchen area in our carport that works.
Let the cobs cool. Set it on end and run your knife down the sides, cutting off the kernels. You want to aim for 2/3 of the kernels. Avoid cutting into the cob itself.
- You can use a large cookie sheet to catch the kernels; a large flat dish like a cake pan would also work.
- Use an electric knife: I’ve never done this but it sounds like a great idea.
- Use a bundt pan: Set your corn on end on the center piece and let the kernels fall into the pan. I’ve tried this and it seems awkward to me. I list it here because I have seen others rave about doing it this way. Try it, and you may just like it.
