When Does Zucchini Go Bad?

Updated April 17, 2017

Zucchini is a type of summer squash that produces an abundant yield. Fresh zucchini lasts for about a week, but zucchini freezes well. For best results, pick zucchini and other summer squash when they are 4 to 8 inches long. Larger zucchini are less tender and flavourful.

Storing Fresh Zucchini

Store fresh zucchini in a perforated plastic bag to allow ventilation. Fresh zucchini will last about a week, but do not keep zucchini in the refrigerator for more than four days.

Freezing Zucchini

Cut zucchini into cubes or slices and blanch in water. Chill the zucchini pieces in ice water before freezing. Alternately, grate zucchini and freeze it in freezer bags or freezer containers.

Uses for Zucchini

Zucchini is a versatile vegetable, delicious fresh, steamed or in marinated salads, stir-fry dishes, muffins, cookies, meat loaf, bread and chutney.
