Ingredients

Scale

Sweet Potatoes

2–3 sweet potatoes, cut in halves or cubed
2 tablespoons olive oil
2 teaspoons toasted sesame seeds
1–2 tablespoons scallions, chopped small

Miso Butter

4 tablespoons unsalted butter, softened
1 tablespoon sweet white miso paste
1/16 teaspoon ground ginger (a very small pinch)
Few turns cracked black pepper

Instructions

Preheat the Oven: Preheat your oven to 425 degrees Fahrenheit to ensure it reaches the optimal temperature for roasting the sweet potatoes evenly and developing a golden, caramelized crust.
Prepare the Miso Butter: In a small mixing bowl, combine the softened unsalted butter, sweet white miso paste, ground ginger, and cracked black pepper. Mix thoroughly until all ingredients are well incorporated and the butter has a uniform texture. Set this flavor-packed mixture aside.
Prepare the Sweet Potatoes: Wash and slice the sweet potatoes in half or cube them as desired. Place them cut-side down on a baking tray and drizzle evenly with olive oil. This helps crisp the exposed surfaces and lock in moisture during roasting.
Roast the Sweet Potatoes: Roast the sweet potatoes cut-side down for 28 to 30 minutes, or until the cut surface turns golden brown. Then flip the sweet potatoes over and continue roasting for another 15 to 20 minutes until they become fork tender, indicating they are fully cooked and soft inside. Remove from the oven once done.
Assemble and Serve: While still warm, top each roasted sweet potato half with a generous dollop of the prepared miso butter. Sprinkle the sesame seeds and chopped scallions over the top to add nuttiness and freshness. Serve immediately to enjoy the melty, savory flavors at their best.

Notes

Use sweet white miso paste for a mild, sweet flavor that balances well with butter.
Adjust ginger quantity to taste; a small pinch adds warmth without overpowering.
To toast sesame seeds, dry roast them in a skillet over medium heat for 2-3 minutes until fragrant.
Sweet potatoes can be cubed instead of halved for faster roasting but adjust the cooking time accordingly.
This dish pairs well as a side for grilled meats or as a vegetarian main.
