Fortunately, freezing zucchini and other summer squash is a snap: All you do is cut it into half-inch slices, blanch it in a pot of boiling water for three minutes, transfer it to a bowl of ice water to cool, drain it, and bag it.
Best Answer: Most articles say you can store zucchini from 4 days to 1 week in a refrigerator. This site says: Summer squash is very perishable and should be refrigerated in a plastic bag for no more than 5 days.. http://www.epicurious.com/tools/fooddict... Under special conditions, zucchini can last longer: Summer squash and zucchini can be stored 1 to 2 weeks under optimum conditions. Bruising the stem or fruit, or scraping the skin during harvest will promote decay and water loss and reduce shelf life. Squash stems should be cut cleanly from the vine.
