Ingredients
  

  • 2 sweet potatoes

For the miso butter

  • 4 tablespoons unsalted butter
  • 2 tablespoons white miso (see Note 1)
  • 1 garlic clove minced
  • 3 tablespoons minced green onions
  • ½ teaspoons lemon juice
  • ½ teaspoons ground cinnamon
  • ¼ teaspoons ground ginger
  • teaspoons ground nutmeg optional

Instructions
 

  • Preheat the oven to 425°F (220°C).
  • Prep the sweet potatoes: Wash 2 sweet potatoes, then cut them in half lengthwise. Place them cut side down on a parchment-lined baking sheet and roast for about 30-45 minutes, or until they’re tender.
  • Make the miso butter: Microwave 4 tablespoons unsalted butter in a small bowl for about 10 seconds until it’s soft and creamy. Then, add 2 tablespoons white miso, 1 garlic clove (minced), 3 tablespoons minced green onions, ½ teaspoons lemon juice, ½ teaspoons ground cinnamon, ¼ teaspoons ground ginger, and ⅛ teaspoons ground nutmeg. Stir everything together until it's well mixed.
  • Assemble the dish: Once the sweet potatoes are ready, transfer them to a plate and fluff them with a fork. Top with the miso butter and enjoy!

Notes

  • (Note 1) Types of Miso: You can swap white miso for other varieties, but keep in mind they tend to be saltier. Be sure to adjust the amount to balance the flavor!
  • Serving Suggestions: Serve these roasted sweet potatoes with miso butter just like you would regular baked sweet potatoes! They pair perfectly with grilled chicken, veggies, or any of your favorite sides.
 
Storage & Reheating Instructions
  • Roasted sweet potatoes: Once cooled, store in an airtight container in the fridge for 4-5 days. For longer storage, wrap each one tightly in plastic wrap, place them in an airtight container or freezer bag, and freeze for up to 6 months.
  • Miso butter: Keep in a separate airtight container—up to 1 week in the fridge or 1 month in the freezer.
  • To reheat: Wrap sweet potatoes in aluminum foil and bake at 350°F—about 10 minutes from the fridge or 20-30 minutes from the freezer. You can also remove the foil and microwave until warm.
