Servings 6


  • 2 lbs. sweet potatoes peeled and cut into 1-inch pieces
  • 1/4 cup plus 2 Tbsp. unsalted butter, softened
  • 1 Tbsp. miso paste
  • 1/4 tsp. black pepper
  • 3/4 cup vegetable broth warmed
  • 1/2 tsp. kosher salt
  • Fresh thyme leaves for garnish


  • Place the potatoes in a large steamer basket over a pot of boiling water. Cook until fork-tender, about 30 minutes.
  • Meanwhile, prepare Miso Butter by creaming 2 Tbsp. of the butter and miso paste together with a fork. Add black pepper and set aside.
  • Mash sweet potatoes by hand using a rice or masher, or blend in a food processor or blender until smooth. Add remaining 1/4 cup softened butter, broth, and salt.
  • Transfer to a bowl and immediately top with Miso Butter, which will melt into the potatoes from the residual heat. Garnish with fresh thyme leaves.
