Which One Is Correct – Is Cucumber a Fruit or Vegetable?

The correct answer is: fruit.

Botanically, a fruit is the part of a plant that develops from a flower and contains seeds. Cucumbers grow from the flower of the cucumber plant and have seeds inside, which makes them a fruit.

Vegetables, on the other hand, are any other edible parts of plants such as roots, stems, or leaves. Carrots, potatoes, and spinach are classic vegetables. While we often treat cucumbers as vegetables in salads or cooking, scientifically, they belong to the fruit category.
