Main Ingredients

  • 2 medium sweet potatoes
  • 4 tablespoons unsalted butter
  • 2 tablespoons white miso paste
  • 1 tablespoon maple syrup
  • 1 teaspoon rice vinegar
  • 1 teaspoon sesame seeds for garnish
  • 2 green onions sliced, for garnish

Instructions
 

Preparation

  • Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
  • Wash and peel the sweet potatoes, then cut them into 1-inch (2.5 cm) cubes.

Cooking

  • In a small bowl, whisk together the melted unsalted butter, white miso paste, maple syrup, and rice vinegar until smooth.
  • In a large bowl, toss the sweet potato cubes with the miso butter mixture until evenly coated.
  • Spread the coated sweet potatoes in a single layer on the prepared baking sheet.
  • Roast for 25-30 minutes, flipping halfway through, until the sweet potatoes are tender and slightly caramelized.

Serving

  • Transfer the roasted sweet potatoes to a serving dish.
  • Garnish with sesame seeds and sliced green onions before serving.

Notes

For extra crispiness, you can broil the sweet potatoes for the last 2-3 minutes, watching carefully to prevent burning. Adjust the amount of miso paste to your taste; some prefer a stronger umami flavor. This dish can be made ahead and reheated, though it's best served fresh.
