No, potatoes are not legumes. They are classified as a vegetable, specifically, a tuber. Legumes, on the other hand, belong to the family Fabaceae, which includes beans, lentils, and peas.
The Difference Between Legumes and Tubers
The confusion between legumes and tubers stems from their shared characteristic of being plant-based foods high in carbohydrates. However, they fall under different botanical families and have distinct nutritional profiles and culinary uses.

Legumes: The Protein Powerhouses
Legumes belong to the Fabaceae family, also known as the pea family. They grow in pods that enclose seeds, which we commonly consume as beans, lentils, chickpeas, and peas. They’re known for being rich in protein and fiber, which makes them a staple in vegetarian and vegan diets.
Tubers: Starchy Delights
Tubers, on the other hand, are part of the Solanaceae family, which also includes tomatoes, peppers, and eggplants. They grow underground on the roots of plants. Potatoes are the most popular type of tuber. They’re high in carbohydrates, making them a significant source of energy.
Nutritional Variations
In addition to the differences in their botanical classification, potatoes and legumes also have different nutritional compositions. While both are excellent sources of fiber and carbohydrates, legumes generally have a higher protein content, making them an important part of a plant-based diet.
On the other hand, potatoes are well-known for their vitamin C content and are a great source of vitamin B6. They are also a fantastic source of potassium, even more so than the popular banana!

In the Kitchen
In the culinary world, potatoes and legumes also have distinct uses. Potatoes’ starchy nature makes them versatile in cooking, starring in dishes from mashed potatoes to crispy fries. Legumes, on the other hand, are typically used in soups, salads, and as meat substitutes due to their high protein content.
In conclusion, while potatoes and legumes both have their unique benefits and uses, they are quite different from each other, starting from their botanical classification to their nutritional composition and culinary uses. Happy cooking!
