Freezing Zucchini vs. Canning Zucchini: Which is Best?
When deciding whether to freeze or can zucchini, it’s essential to consider factors such as available storage space, time commitment, and the final texture of the zucchini. According to Michigan State University Extension, freezing zucchini is one of the best methods for preserving vitamins and requires minimal equipment.
However, canning zucchini—especially non-pickled varieties—requires a pressure canner due to the vegetable’s low acidity. This means that while canning zucchini requires more effort, it provides a longer shelf life compared to freezing.

- Cut the zucchini into slices, cubes, or shred it if you plan to use it in baking later.
- Blanch the zucchini in boiling water for 2-3 minutes, then immediately transfer it to an ice bath to stop the cooking process.
- Pack the zucchini into freezer-safe bags or containers, leaving some headspace for expansion.
