Description
These Mashed Sweet Potatoes with Miso Butter are velvety, rich, and full of umami depth. The combination of earthy sweet potatoes and savory miso butter creates a comforting side dish that pairs perfectly with roasted meats, tofu, or holiday mains.
Ingredients
- 2 lbs sweet potatoes, peeled and cut into 1-inch pieces
- 1/4 cup plus 2 Tbsp unsalted butter, softened
- 1 Tbsp miso paste
- 1/4 tsp black pepper
- 3/4 cup vegetable broth, warmed
- 1/2 tsp kosher salt
- Fresh thyme leaves, for garnish
Instructions
- Steam the sweet potatoes: Place the potatoes in a large steamer basket over a pot of boiling water. Cook until fork-tender, about 30 minutes.
- Prepare the Miso Butter: While the potatoes steam, combine 2 Tbsp of softened butter with the miso paste. Mix with a fork until smooth, then stir in black pepper. Set aside.
- Mash the potatoes: Using a masher or food processor, mash the sweet potatoes until smooth. Add the remaining 1/4 cup butter, warm vegetable broth, and salt. Stir until creamy and well combined.
- Finish and serve: Transfer the mashed sweet potatoes to a serving bowl. Top with the prepared Miso Butter—it will melt beautifully into the hot mash. Garnish with fresh thyme leaves before serving.
Notes
- Tip: White or yellow miso paste adds mild, savory flavor. Red miso can be used for a stronger umami punch.
- Make ahead: Prepare up to 1 day ahead and reheat gently on the stovetop or microwave before topping with Miso Butter.
- Serving idea: Excellent alongside roasted chicken, glazed salmon, or a holiday feast.
