Instructions

Step 1: Preheat oven to 400°F. Toss 2 lbs peeled and cubed sweet potatoes with 2 tbsp vegetable oil and spread evenly on a baking sheet. Roast for 25-30 minutes, turning halfway until tender and edges are caramelized.
Step 2: Meanwhile, in a small bowl whisk together 3 tbsp white miso paste, 2 tbsp soy sauce, 1 tbsp rice vinegar, 1 tbsp brown sugar, and 2 tsp sesame oil until smooth.
Step 3: When sweet potatoes are done roasting, transfer to a large bowl and pour the miso glaze over them. Toss gently to coat each cube evenly.
Step 4: Return glazed sweet potatoes to the baking sheet and roast an additional 5 minutes to set the glaze.
Step 5: Remove from oven, sprinkle with 1 tbsp toasted sesame seeds and 2 thinly sliced green onions before serving warm.
