Fun facts

  • Zucchini is a summer squash harvested while still young. The name is Italian for "little squash", since this variety was developed and named in Italy.

Choosing and storing

Choose small to medium zucchini that feel firm, with glossy skin and no soft spots. The bigger they get, the more seeds and water they usually have, and the less sweet they taste. Store zucchini in the crisper drawer in a paper or loosely open bag and use within about a week. Do not wash before storing, since moisture makes them spoil faster.

Cooking it well

Zucchini is full of water, so a quick stir-fry over high heat for a few minutes is enough to cook it while keeping some bite, while long cooking turns it mushy. Zucchini noodles are an easy way to add vegetables while still enjoying a bowl of noodles, just blanch them briefly or toss them raw with sauce. Short cooking also keeps more vitamin C, see does cooking destroy vitamin C.

Frequently asked questions

Do you need to peel zucchini?
No. The skin is thin and turns tender when cooked, so just wash it well.
Can you eat zucchini raw?
Yes. Young zucchini, thinly sliced or spiralized, works well raw in salads. If one tastes unusually and strongly bitter, throw it away.
