On the other hand, if the discoloration or soft spots is throughout the entire vegetables, it’s best to throw them out. Trying to cook spoiled zucchini will not only taste bad, but it could also make you sick.

Another way to check the zucchini for freshness is to check the exterior of the vegetable. If it’s slightly rubbery, it’s a sign that it’s starting to lose freshness. It’s recommended to not serve them raw. Instead, cut them up and cook them in soups, stews, or stir-fries.

If on the skin is covered with rotten spots or molds, it’s best to throw them out.

However, if the zucchini is firm and plump, with the skin glossy, this is a sign that it’s fresh. These quality zucchini can be used to prepare any kind of meal.
