Instructions

Step 1: Preheat the oven to 400°F. Toss 3 cups peeled and cubed sweet potatoes with 1 teaspoon sesame oil in a large bowl until evenly coated. Spread the sweet potatoes on a baking sheet in a single layer.
Step 2: Roast the sweet potatoes for 25 minutes, flipping halfway through, until tender and lightly browned on edges.
Step 3: Meanwhile, whisk together 3 tablespoons white miso paste, 2 tablespoons mirin, 1 tablespoon soy sauce, and 1 tablespoon brown sugar in a small bowl until smooth.
Step 4: Remove sweet potatoes from the oven and brush them evenly with the miso glaze. Return to the oven and roast for an additional 10 minutes until the glaze is caramelized and sticky.
