Yams vs. sweet potatoes… Are they really the same or are they different vegetables? There are many varieties of sweet potatoes and yams, so let’s learn about their distinct characteristics, when to use them, and how to incorporate them into any dish—even Thanksgiving dinner!

Sweet potatoes are peeled and chopped into cubes.

What is a yam?

Yams are a root vegetable with a bark-like, brown skin (almost wart-like looking) and a very light, pale white flesh. Yams have more of a neutral flavor and often complement the flavors of other ingredients in your dish. They are a plant species from the dioscorea family that originate from West African cuisines and parts of Asia. There are multiple different types, including white, yellow, and purple, to name a few. Yams can be prepared by baking, boiling, and frying. 

What is a sweet potato?

Sweet potatoes have a sweet taste and soft texture when cooked. Their flesh is commonly orange, but can also be white or purple. Sweet potatoes are more widely found in American grocery stores, but they are distinct from more “regular” potatoes like Russets. They come from the ipomoea batatas plant family and originate from Central and South America and the United States. Sweet potatoes have become more popular over the years because of their nutritional profile, so check out this Are sweet potatoes healthy? post that talks all things health benefits.
