Did you know that zucchini is actually a summer squash, and it hates the cold? Refrigeration below 40°F (around 4°C) can cause “chilling injury.” This makes the skin pucker, the flesh go mealy, and speeds up spoilage—which is ironic, since we store it there to keep it fresh.
For best results, keep your zucchini in the warmest part of the fridge—usually the crisper drawer—in a perforated plastic bag. This buys you about five to seven days of prime time, after which the clock starts ticking faster.
The Smell Factor (Trust Your Nose)
Here’s a hard truth: a bad zucchini has a very distinct, almost fermented odor. It’s not a subtle “earthy vegetable” scent; it’s a sharp, sour, or vaguely boozy smell. If your nose crinkles in disgust, your taste buds will thank you for tossing it.
Fun fact: zucchini is 95% water, so when it starts to rot, that water ferments fast. That’s why a bad one can go from “meh” to “moldy” in what feels like 24 hours.
