You can freeze cucumbers, but it helps to choose the right use first. Their high water content means thawed cucumber is soft, so it works best in blended, chilled-soup, sauce or relish-style recipes rather than raw salads.
Quick reference chart

Step-by-step method
- Wash the cucumber, dry it and remove any damaged areas.
- Choose the intended use: slice for smoothies or soup, or grate and salt it for relish-style recipes.
- For sliced cucumber, arrange pieces in one layer on a lined tray and freeze until firm.
- Transfer frozen slices to a labelled airtight freezer bag, pressing out excess air.
- For grated cucumber, mix with a little salt, leave it briefly to draw out water, squeeze gently, then pack in small portions.
- Thaw in the fridge and drain excess liquid before adding cucumber to a blended, cooked or relish-style recipe.
Why does frozen cucumber go soft?
Cucumber contains a lot of water. That water freezes into ice crystals and breaks down the crisp structure, so the thawed pieces are soft.
Is freezing or pickling better for cucumbers?
Pickling is better when you want a crisp, tangy condiment. Freezing is better when you want cucumber ready for soups, smoothies, sauces or cooked dishes.
Can you use frozen cucumber in smoothies?
Yes. Frozen cucumber can go straight into a smoothie, where the softer texture is not noticeable.
