It is not recommended to freeze whole, raw cucumbers. When frozen, the high water content in raw cucumbers will form large ice crystals that can damage the cell structure. This results in a mushy, waterlogged texture when thawed.

For best results, cucumbers should be sliced or processed before freezing. This helps minimize damage to the texture from freezing. The exceptions are miniature or pickling cucumber varieties, which have a lower water content and can be frozen whole with slightly better results.

How to Prepare Cucumbers for Freezing

Wash cucumbers thoroughly and slice into 1/4 to 1/2 inch rounds or cubes.
In a colander, toss cucumber slices with 1-2 teaspoons of kosher salt. This helps draw out excess moisture.

Arrange in a single layer on a parchment-lined baking sheet and place in freezer. Freeze until solid, about 1-2 hours.
Transfer frozen cucumber slices to ziplock freezer bags or airtight containers. Squeeze out excess air and seal.
Store frozen cucumbers for up to 10-12 months.

You can also freeze cucumbers grated or puréed. This is a great option for using up surplus garden cucumbers.
