A comforting and umami-packed side dish combining naturally sweet Japanese sweet potatoes with savory miso butter for a creamy, flavorful mash.

Ingredients

Scale
  • 2 medium Japanese sweet potatoes (about 500g / 1.1 lbs), peeled and cut into chunks
  • 3 tablespoons (about 43g) unsalted butter, softened
  • 2 tablespoons white miso paste
  • 1/4 cup (60ml) warm milk (whole milk or dairy-free alternative like oat milk)
  • Salt, to taste
  • Pinch of freshly ground black pepper
  • Optional garnish: toasted sesame seeds or finely chopped chives

Instructions

  1. Peel about 2 medium Japanese sweet potatoes (roughly 500g/1.1 lbs) and cut them into roughly 1-inch (2.5 cm) chunks.
  2. Place the chunks in a medium pot and cover with cold water. Add a pinch of salt. Bring to a boil over medium-high heat, then reduce to a simmer and cook until potatoes are very tender when pierced with a fork—about 15-20 minutes.
  3. Drain the potatoes well in a colander. Return them to the hot pot off the heat and let them sit for 2-3 minutes to evaporate any excess moisture.
  4. While potatoes cook, combine 3 tablespoons softened unsalted butter with 2 tablespoons white miso paste in a small bowl. Mix until smooth and fully incorporated.
  5. Using a potato masher or fork, mash the sweet potatoes until mostly smooth but still a bit rustic. Pour in 1/4 cup (60ml) warm milk gradually, mashing and stirring until creamy and desired consistency is reached.
  6. Add the miso butter mixture to the mash. Fold gently with a spatula or spoon until the mash turns silky and evenly tinted. Taste and add salt sparingly.
  7. Add a pinch of freshly ground black pepper. Optionally, sprinkle toasted sesame seeds or chopped chives on top. Serve immediately.

Notes

Use good-quality white miso paste for the best umami flavor. Avoid overmixing to keep a rustic texture and prevent gluey mash. Let the mash rest a few minutes after mixing to meld flavors. For a vegan version, substitute butter with plant-based margarine or coconut oil and use dairy-free milk.
