Ingredients

2 pounds sweet potatoes, peeled and cut into 1 ½ inch chunks
4 tablespoons unsalted butter, at room temperature
2 tablespoons miso paste (red or white)
⅓ cup whole milk (more as needed)
½ teaspoon kosher salt (plus more to taste)
Freshly ground black pepper, to taste
2 scallions, thinly sliced (optional, for garnish)

Instructions

1
Place sweet potatoes in a large pot and cover with cold, salted water. Bring to a boil, reduce to a simmer, and cook 15-18 minutes, until fork-tender.
2
Drain sweet potatoes well. Return to the pot over low heat for 1 minute, stirring gently, to evaporate any extra moisture.
3
Add butter and miso paste to the hot sweet potatoes. Mash until mostly smooth.
4
Gradually add milk, mashing, until you reach a creamy consistency.
5
Season with salt and pepper to taste. Transfer to a serving bowl and top with sliced scallions. Serve immediately.
