Zucchini is a Fruit

Botanically, a fruit is the ripened ovary of a plant’s flower.  When a zucchini develops, it does so from a zucchini plant flower. 

Fruit also contains seeds for reproduction. Zucchinis contain seeds. They scientifically fit the definition of fruit.

Zucchini is botanically known as Cucurbita pepo andbelongs to the Cucurbitaceae family.  Their classification as pepo makes them a berry.  Berries feature a three-layered design.

A berry contains all three layers with the outer skin named the exocarp. The fleshy middle layer is called the mesocarp. An inner layer holding seeds is referred to as the endocarp.

Berries are born from a single bloom with a single ovary.  They must contain at least two seeds, hence, the zucchini qualifies!

Zucchini flowers are also edible and are often fried as a great appetizer or side dish.

Zucchini is a Vegetable

Vegetables are classified as the edible parts of plants that are not fruit. These edible parts include the roots, leaves, tubers, and stems of plants.

In these terms, zucchinis are botanically considered as fruit. But a broader definition of vegetables includes fruit because it is an edible part of a plant. In this sense, all fruits would also be vegetables.

Even for the United States Department of Agriculture (USDA), zucchini is in the Vegetable Group list.

People who prepare and eat zucchini generally consider them a vegetable due to their culinary use. Zucchini resemble cucumbers, which are also fruit. Like cucumbers, they are prepared in savory cuisine most of the time.

Zucchinis are highly palatable when baked, fried, roasted, grilled, or seared. They can be used in salads, stir fries, pasta, and rice dishes, and in side dishes. So, while science labels them a fruit, other people legitimately consider them a vegetable.

The one exception to this may be their use in zucchini bread which is sweeter. This is, however, an exception.
