Sweet Potatoes vs Yams
The names for these root vegetables are often used interchangeably, which can make things confusing if you’re not sure which to use in a recipe.
Sweet potatoes have a smooth skin that comes in a variety of colors, while yams have a rough, bark-like skin that’s difficult to peel.
Yams are also more starchy than sweet potatoes, and the flavor is closer to a white russet potato. True yams are uncommon in the US and are usually only found in international or ethnic food stores.
Most often, what you’ll find at the grocery store is a sweet potato with darker skin and orange flesh. Because this variety is newer than the kind with golden skin and light yellow flesh, producers label them yams to differentiate between the two. For another delicious roasted vegetable, try this roasted kabocha squash.
Simply put, whether what you find at your local store is labeled sweet potato or yam, it’s very likely that they are just different varieties of the same vegetable.
The kind with darker skin and orange flesh is what you’ll need to make this potato soup recipe.

How to clean and cut sweet potatoes
- Rinse and lightly scrub the outside of the potato with a vegetable brush to remove any dirt. Then use a peeler to remove all of the skin from the flesh.
- Cut off the pointy ends and discard. Make thick lengthwise slices, then cut those slices into sticks. From there, chop the sticks into thick cubes.
- Another option is to slice the entire sweet potato into rounds, then cut those into smaller pieces.
Tip: Cut the sweet potatoes into similar size pieces so they roast evenly.
How to Make Sweet Potato Soup
- Spread the sweet potatoes and onion out on a large sheet pan. Drizzle with olive oil, add the spices, and toss everything to coat the vegetables well.
- Place the sheet pan in the oven to roast. It will be ready when a fork can be easily inserted into the sweet potatoes without them feeling mushy.The onions will also have a nice caramelized color to them.
- Add the roasted vegetable mixture to a blender along with the liquid. Blend for a few minutes until everything is smooth and creamy. Taste the soup and add salt and pepper as needed.If you don’t have a blender, a large food processor will work. You can also add everything to a saucepan and blend with an immersion blender.
- Heat in a saucepan if needed. If the soup is too thick, add water or stock a little at a time until it’s the desired consistency. Serve and enjoy!
After you make the soup, serve it warm, while it’s still fresh.
Any leftovers should be kept in the refrigerator and used within a few days. However, the soup freezes well. It will keep frozen for up to 3 months.
