Can you freeze raw zucchini?

Zucchini can be frozen raw, but it is not recommended to do so. Like all organic matter, zucchini contains enzymes that begin to breakdown the vegetable and cause loss of nutrients and discolouration even while frozen.

Zucchini should be blanched prior to freezing in order to keep it tasting fresh. To blanch zucchini, use the desired preparation method, such as chopping or slicing, and then bring a pot of water to a roiling boil. Drop the zucchini into the pot and let it boil for thee to four minutes. Remove it from the pot, and allow it to cool before placing into plastic bags or another container suitable for freezing.
