Baked until tender and fluffy then sliced open and filled a generous serving of umami-rich miso butter, these Roasted Japanese Sweet Potatoes are a simple and delicious side dish for almost any meal. Serve them with chicken, pork, fish, or a simple salad.
Japanese sweet potatoes (also known as satsumaimo) are insanely flavorful. Less candy-sweet than traditional orange sweet potatoes, these starchy root vegetables have a more subdued chestnut flavor and distinctly dense, velvety texture.
After baking, the potatoes are sliced open, fluffed with a fork and mounted with heaping spoonfuls of miso compound butter–swoon!

Ingredients:
Here’s everything you’ll need to make this recipe: Japanese sweet potatoes, butter, white or yellow miso paste, green onions, olive oil, and salt.
Recipes Step by Step:
Step 1. Roast the Potatoes
Wash the potatoes well then place them on a lined baking sheet. Rub them with a thin, even layer of olive oil then sprinkle with salt. Bake until completely soft and tender. To check for doneness: insert a pairing knife into the thickest part of the potato. If it goes in easily, with no resistance, it’s done.
Pro tip: Sweet potatoes tend to release sugary liquid while baking which can caramelize and burn onto your baking tray. Lining the pan with parchment paper or a silicone baking mat ensures an easy clean up.
Step 2: Make the Miso Butter
While the potatoes are baking whisk together the miso butter. Set aside.
Step 3: Serve
To serve, use a paring knife to slice halfway through the potato lengthwise, give it a gentle squeeze to open then use a fork to fluff up the interior flesh. Top each potato with miso butter, sliced green onion and salt.
