Step-by-Step Instructions for Making Mashed Sweet Potatoes with Miso Butter

  1. Steam the Sweet Potatoes: Peel and cut the sweet potatoes into 1-inch pieces. Place them in a steamer basket over a pot of boiling water and cook until fork-tender, which should take about 30 minutes.
  2. Prepare the Miso Butter: While the potatoes are steaming, mix softened butter with miso paste and black pepper. Set aside.
  3. Mash the Sweet Potatoes: Once the sweet potatoes are tender, mash them using a potato masher, food processor, or blender. For a chunkier texture, you can hand-mash them.
  4. Mix in the Flavor: Add vegetable broth (or milk of choice), salt, and the remaining softened butter. Stir everything together until smooth and creamy.
  5. Top with Miso Butter: Transfer the mashed sweet potatoes to a bowl and immediately top with the prepared miso butter. The heat from the potatoes will melt the butter, creating a smooth, savory topping. Garnish with fresh thyme leaves for a beautiful presentation.

  • Sweetened Version: For a slightly sweeter twist, add a drizzle of maple syrup or brown sugar to the mashed sweet potatoes before serving.
  • Spicy: Add a little sriracha or chili flakes to the miso butter for an extra kick of heat.

Where can I buy miso paste?
