How to Make Roasted Japanese Sweet Potatoes with Miso Butter

Preheat the oven to 375°F. Get your baking tray ready by lining it with parchment paper or a silicone baking mat to prevent sticking and make cleanup a breeze.
Poke each potato with a fork or small knife at least 10 times on all sides. This step allows steam to escape while baking. Place them on the prepared baking sheet and drizzle generously with olive oil and salt.
Bake the sweet potatoes in the oven for about 1 hour. Flip them halfway through to ensure even cooking. They should be completely soft and tender when done; you’ll know they’re ready when a fork easily glides through.
Whisk together the miso and butter in a small bowl while the potatoes bake. This creamy mixture will elevate your dish! Set it aside for later use as the flavors meld beautifully.
Serve by cutting each potato open lengthwise with a sharp knife. Fluff the insides gently with a fork to create a fluffy texture. Spoon about half of the miso butter mixture into each potato, top with sliced green onion, and sprinkle with a little more salt for extra flavor. Enjoy immediately!

Optional: For an extra pop of flavor, drizzle a bit of additional olive oil on top before serving.
