  • Place the potatoes flesh side down on an aluminum-lined sheet tray and roast in the oven for 30-35 minutes until the flesh is fully cooked and is easily pierced with a fork.

Make the miso butter sauce

  • While the potatoes are roasting, mix the miso, sake, mirin, and granulated sugar in a small bowl until combined.
  • Add the sauce to a small saucepan and cook on the stove over medium-low heat for five minutes, stirring very frequently. Make sure that you scrape the bottom of the pan often to move the sauce around and prevent scorching.
  • Add the butter to the sauce and cook for an additional three minutes, stirring very frequently.

Broil the potatoes and serve

  • Once the potatoes are finished baking, remove them from the oven and turn your oven’s broiler to high heat.
  • Flip the potatoes over on the sheet pan so that they’re cut side up and use a pastry brush to apply the sauce on top of the potato flesh.

  • Broil the potatoes in the oven for 1-3 minutes until the glaze is beginning to caramelize.  Check the potatoes frequently to avoid burning them.
  • Once the potatoes are done broiling, place them on a serving plate and garnish them with the sliced scallions and sesame seeds, and serve.
