Cucumbers are one of the most popular sliced veggies added to salads, sandwiches, and platters. But you may be surprised to learn that botanically speaking, cucumbers are actually a fruit!

So why are cucumbers consistently referred to and prepared as vegetables in the culinary world? Let’s take a look at the key differences between fruits and vegetables and where cucumbers fall among both categories.

Characteristics of Fruits

In botany, fruits are defined as the part of a plant that contains seeds and provides protection and nutrient support for these seeds as they develop. Some identifying qualities of fruits:

  • Grow from the ovary of flowers after pollination
  • Enclose and surround seeds until maturity
  • Have a fleshy or juicy texture when ripe
  • Most have a sweet, tart or savory taste at maturity
  • Provide protective fiber, vitamins, and minerals

By these criteria, cucumbers do qualify as a fruit. Cucumbers surround and nourish seeds as they mature and contain key nutrients like vitamin K, magnesium, and potassium.

Comparing Cucumbers to Vegetables

Although botanically a fruit, cucumbers are prepared and eaten as vegetables. Here are some key reasons cucumbers seem more like veggies:

  • Savory, mild taste – Cucumbers lack the sweetness of most fruits. Their flavor is mild and savory, ideal for salads.
  • Culinary uses – Cucumbers are served raw or pickled alongside main dishes. Fruits are more often desserts.
  • Nutritional profile – Cucumbers provide hydration and daily vitamins and minerals. They lack the sugars and calories of fruits.
  • Texture – Cucumbers have a juicy yet firm, crunchy flesh unlike soft, pulpy fruit flesh.
  • Growing on vines – Cucumbers grow along low trailing vines spread over the ground, similar to squash, melons, and other veggies.

So while cucumbers are biologically fruits, their culinary traits align more closely with vegetables consumed in savory dishes for nutrition.

Why Cucumbers Are Seen as Vegetables?

Even though they meet the technical definition, cucumbers are generally referred to as vegetables because:

  • Lack a sweet taste – Cucumbers have a subtly flavored, watery flesh unlike sugary fruit.
  • Mainly contain fiber and water – Cucumbers provide hydration and fiber. They lack substantial carbohydrates and calories.
  • Primarily served raw – Cucumbers are most often eaten fresh or pickled, not cooked like fruits.
  • Vegetative plant part – The edible portion develops from the stem, similar to squash and peppers.
  • Used in savory dishes – Cucumbers are widely incorporated into salads, sides, sandwiches and platters as a vegetable.

Ultimately, the culinary purpose and mild flavor of cucumbers make them better suited to be prepared as vegetables, even though they are technically fruits.


Botanically cucumbers meet the qualifications of fruits. However, their culinary usage and nutritional profile mean they are viewed as vegetables in most contexts. So while cucumbers are actually fruits, you can feel comfortable continuing to enjoy them as fresh, tasty vegetables!
