Ingredients

  • 5 large sweet potatoes
  • 1.5 tablespoons olive oil
  • 1/4 teaspoon salt divided
  • 1/4 teaspoon ground pepper divided
  • 1 head garlic
  • 1/3 cup full-fat Greek yogurt or sour cream
  • 2 tablespoons unsalted butter room temperature
  • optional garnish: fresh thyme
  • optional topping: unsalted butter

Instructions

  • Preheat the oven to 375ºF. Spray a large casserole dish or baking sheet with nonstick cooking spray. Set aside.
  • Prepare the sweet potatoes and garlic. Cut off each end of the potatoes, then slice them in half long-ways (hot-dog style). Cut off the pointy end of the head of garlic to expose the cloves.
  • Place the sweet potatoes and garlic head on prepared baking pan, cut-side up. Drizzle with olive oil and season with 1/8 teaspoon salt and 1/8 teaspoon pepper.

  • Use a spoon to scoop out the flesh of the sweet potatoes and place the flesh into a large bowl. Skip this step if you want mashed sweet potatoes with the skin on.

  • Use a hand mixer or immersion blender to mix everything together until smooth. Garnish with fresh thyme and serve topped with additional butter.

Notes

  • Storage: Let the mashed sweet potatoes cool completely, transfer to an airtight container, and refrigerate for up to 5 days.
  • Reheating Mashed Sweet Potatoes: When ready to serve, warm the potatoes up in the microwave or transfer to an oven-safe baking dish and heat until warmed through. You may need to mix in a splash of milk or a dollop of Greek yogurt to thin the potatoes out a little bit.
