Yam vs. Sweet Potato—What’s The Difference?
Many people use the words "yam" and “sweet potato” as if they mean the same thing, but they're actually two different foods. They may look similar, but their taste, texture, and origin set them apart.
Knowing the difference can help you choose the right one for your recipes and understand what you’re really eating.
The true definition
True yams are native to Africa and Asia, with rough, bark-like skin and starchy white flesh. They're dry and mild in flavor, more like a regular potato.
Sweet potatoes, on the other hand, have smoother skin and moist, sweet flesh that ranges in color from orange to purple.
Most "yams" sold in U.S. grocery stores are actually sweet potatoes.
Texture and flavor
Sweet potatoes are sweet, soft, and caramelize beautifully when baked or roasted.
Yams are starchier and best boiled, pounded, or fried.
For most recipes, especially holiday favorites, sweet potatoes are the better choice for their flavor and versatility.
Making the right choice
The next time you see "yams" at the store, you'll know they’re probably sweet potatoes in disguise. True yams are a different root entirely, and much harder to find outside of specialty markets.
Both have their place in cooking, but understanding the difference helps you pick the right one for your dish—and enjoy it at its best.
