Tomatoes are quite possibly one of the summer season’s most versatile produce offerings.
They’re typically grouped alongside vegetables in the culinary world, but you may have also heard them referred to as fruits.
This article explores whether tomatoes are fruits or vegetables and why they’re sometimes confused for one or the other.
Nutritionally, fruits and vegetables get a lot of attention for being rich sources of vitamins, minerals and fiber (1).
Although they have a lot in common, fruits and vegetables also have some distinct differences.
However, these differences will vary dramatically depending on whether you’re talking to a farmer or a chef.
Botanical classification of fruits and vegetables is primarily based on the structure and function of the part of the plant in question.
When it comes to cooking, the classification system for fruits and vegetables changes significantly compared to how they’re categorized botanically.
In culinary practice, fruits and vegetables are utilized and applied based primarily on their flavor profiles.
Generally, a fruit has a soft texture and tends to err on the sweet side. It may also be somewhat tart or tangy. It’s best suited for desserts, pastries, smoothies, jams or eaten by itself as a snack.
Conversely, a vegetable typically has a blander and possibly bitter flavor. It usually has a tougher texture than fruit and, though some are enjoyed raw, may require cooking. They’re best suited for savory dishes like stir-fries, stews, salads and casseroles.
Summary Whether a food is a fruit or vegetable depends on if it's being discussed in culinary or botanical terms. Botanical classification is based on the structure and function of the plant, while culinary classification is based on flavor and recipe application.
According to science, tomatoes are fruits.
All fruits have a single seed or many seeds inside and grow from the flower of a plant (2).
Like other true fruits, tomatoes form from small yellow flowers on the vine and naturally contain a multitude of seeds. These seeds can later be harvested and used to produce more tomato plants.
Interestingly, some modern varieties of tomato plants have been intentionally cultivated to stop producing seeds. Even when this is the case, a tomato is still considered to be the fruit of the plant in botanical terms.
Summary Tomatoes are botanically fruits because they form from a flower and contain seeds.
Much of the confusion about whether a tomato is a fruit or vegetable comes from the common culinary applications for tomatoes.
Cooking is as much an art as it is a science, which tends to give way to more flexibility for how different foods are categorized.
In cooking, tomatoes are usually used alone or paired alongside other true vegetables in savory dishes. As a result, they’ve earned a reputation as a vegetable, even though they’re technically a fruit by scientific standards.
This was the method of classification used by the US Supreme Court in 1893 during a legal dispute with a tomato importer who argued his tomatoes should be considered fruits to avoid the higher vegetable tariff.
It was during this case that the court ruled the tomato would be classified as a vegetable on the basis of its culinary applications instead of its botanical categorization as a fruit. The rest is history (3).
Tomatoes aren’t the only foods that struggle with this kind of identity crisis. In fact, it's fairly common for plants botanically classified as fruits to be used as vegetables in culinary practice.
Other fruits that are often considered vegetables include:
- Pea pods
Though much less common, sometimes vegetables are utilized more like fruits in certain culinary scenarios, too.
Rhubarb, for example, is often included in sweet dessert-style recipes even though it’s a vegetable. This is also exemplified in other dishes like carrot cake or sweet potato pie.
Summary Tomatoes are usually used in savory preparations, which is why they’ve earned the reputation of being a vegetable. Some other fruits that are used as vegetables include squash, pea pods and cucumber.
Tomatoes are botanically defined as fruits because they form from a flower and contain seeds.
Still, they’re most often utilized like a vegetable in cooking. In fact, the US Supreme Court ruled in 1893 that the tomato should be classified as a vegetable on the basis of its culinary applications.
It’s not uncommon for culinary practices to blur the lines of scientific definitions of what constitutes a fruit or a vegetable. Many plants that are considered to be vegetables are actually fruits.
For all intents and purposes, tomatoes are both. If you’re talking to a farmer or gardener, they’re fruits. If you’re talking to a chef, they’re a vegetable.
Regardless, they’re a delicious and nutritious addition to any diet.
