If you have a bumper crop of zucchini, you might be wondering how best to preserve it. The two most common options are freezing and canning. Both have their advantages, but which method is better for keeping the nutrients, flavor, and texture of zucchini intact? Let’s compare freezing and canning to see which method works best for your needs.
Freezing Zucchini vs Canning Zucchini: Which is Best?
When deciding between freezing zucchini or canning zucchini, it’s essential to consider your available storage, time, and preferred end result. According to Michigan State University Extension, freezing zucchini retains most of its vitamins and requires minimal equipment. However, canning zucchini—especially non-pickled versions—requires a pressure canner due to its low acidity. As a result, canning may take more effort but provides long-term storage.

How to Freeze Zucchini for Long-Term Storage
- Wash the zucchini thoroughly.
- 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.
