How Do You Keep Cucumbers Fresh?

The best way to keep cucumbers fresh is to clean cucumbers and then store them in the fridge for up to one week. Refrigerators can lead to cold injury for fresh cucumbers. However, refrigeration is still the best storage option. Crisper drawers in particular are vital for maintaining the nice crunch of cucumber fruit. Without proper storage, your cucumbers will lose their crunch.

  • Cucumbers are best kept fresh in an airtight container in a refrigerator.
  • Consider wrapping your cucumber in a moist paper towel to help it retain moisture.

It’s important to keep your cucumbers separate from the rest of your food. An airtight container will help maintain moisture and seal in freshness. Moisture maintenance is incredibly important. Though cucumbers are a fruit, they are often mistaken for a vegetable due to their high water content. Ripe cucumbers are over 90% water so you want to maintain their water content at all costs. Excess moisture loss will result in ruined cucumbers very quickly.
