Easy Mashed Sweet Potatoes
Mashed potatoes are indisputably a crowd favorite side dish, which makes it a must when it comes to preparing a spread for the holidays, barbecues or even potluck sessions. With Thanksgiving right around the corner, there’s no other perfect time to divulge this simple recipe!
I am absolutely in love with how creamy the sweet mashed potatoes are, and fusing the miso butter together adds a more earthy flavor. It’s the perfect blend of sweet and savory.
Miso Butter
The spotlight for today is on miso paste, a traditional Japanese condiment made from fermented soybean. It adds on that delicious umami flavor which complements the sweet potatoes flawlessly.
Miso butter is basically mixing up miso paste together with softened butter. It’s also phenomenal when paired with garlic (try this Miso Garlic Butter Salmon!).
Types of Miso
There are 3 types of miso, ranging from ones that has a lighter taste to those that are more pungent due to longer fermentation. For this recipe, I used red miso paste which has the strongest and most assertive fermented flavor amongst the 3.
However, if you are not used to taste, you can try the yellow miso, which is milder but still has the fermented taste. Or you can use white miso (aka shiro miso) that’s more light and sweet.

how to make easy mashed sweet potatoes with miso butter

Notes For Sweet Potato Mash With Miso Butter
- Make extra miso butter to serve with the sweet potato mash for those who would like extra umami flavor. The ratio of butter to miso paste should be 2:1.
- The amount of green onions used should be up to preference.
- Cut sweet potatoes into 1-inch pieces before boiling: The sweet potatoes will cook easier and faster.
- Different texture: Depending on what you use to mash the potatoes, the texture will be different. A potato masher will give you chunkier texture. If you’d like for it to be silky smooth, you can use a blender.
- Miso paste is quite salty, so I don’t season with any additional salt.
- Making ahead and storage: I recommend making them only up to 1 day ahead. Store them in an airtight container and refrigerate. Reheat in the microwave or on the stovetop.
