Yes, you can freeze sweetcorn. For fresh corn, a short blanch before freezing gives the most reliable colour and texture. You can freeze kernels loose in a bag, whole cobs if space allows, or cooled cooked corn for an easy side dish.

Step-by-step method
- Husk fresh sweetcorn and remove as much silk as practical.
- For kernels, cut them from the cob carefully after husking; leave cobs whole if that suits how you will use them.
- Blanch fresh kernels or cobs briefly in boiling water, then cool them quickly in cold water.
- Drain thoroughly and pat dry so excess water does not form large ice crystals.
- Pack labelled portions in freezer bags or airtight containers, pressing out excess air from bags.
- Use kernels straight from frozen in soups, stir-fries, fritters or hot side dishes, and reheat cooked corn until steaming hot.
Do you need to blanch sweetcorn before freezing?
For fresh sweetcorn, blanching is the most reliable option. It helps preserve the corn’s colour and texture, especially when it will stay in the freezer for more than a short time.
Can you freeze sweetcorn on the cob?
Yes. Husk it, blanch it, cool it quickly, dry it well and wrap it tightly. Whole cobs take more room, so kernels are often the more convenient choice.
How do you stop frozen sweetcorn clumping together?
Cool and dry kernels thoroughly before bagging. You can also spread them in a single layer to firm up first, then transfer them to a bag.
