This bold twist on a classic side dish brings sweet, savory, and umami together in perfect balance. Creamy mashed sweet potatoes meet rich miso butter for a silky texture and complex flavor. It’s simple, unexpected, and unforgettable — a standout side for both weeknight dinners and holiday feasts.
3 lbs sweet potatoes, peeled and cubed
3 tbsp unsalted butter
1 tbsp white miso paste
2 tbsp milk or cream (more as needed)
1 tbsp maple syrup (optional for sweetness)
Salt and pepper, to taste
Chopped scallions or sesame seeds, for garnish (optional)
Boil the potatoes: Place sweet potatoes in a large pot, cover with water, and add a pinch of salt. Boil 15–20 minutes until fork-tender.
Make miso butter: While potatoes cook, melt butter in a small saucepan. Whisk in miso until smooth.
Mash: Drain sweet potatoes, return to the pot, and mash. Stir in miso butter, milk, and maple syrup if using.
Season & finish: Add salt and pepper to taste. Mix until creamy.
Garnish: Top with scallions or sesame seeds for a savory finish.
