  • 4 large sweet potatoes
  • 8 tbsp (1 stick) salted butter
  • 1 cup brown sugar lightly packed
  • 3 tablespoon fresh rosemary chopped
  • 2 tablespoon fresh thyme chopped
  • 3 tablespoon fresh oregano chopped
  • ground cinnamon to season
  • salt + pepper to taste


  • Preheat oven to 350 degrees F. Line a large baking sheet or jelly roll pan with parchment paper. Set aside.
  • Wash and scrub your sweet potatoes and dry thoroughly. Cut off the ends of each potato and then cut each potato in thirds (each piece should be approximately 2 inches thick). Transfer the 12 sweet potato sections to the prepared baking sheet.
  • Add the butter to a microwave-safe bowl and cook until just melted (it took me approximately 30 seconds). Generously brush melted butter over each sweet potato (reserve some butter for the next step).
  • In a small bowl, mix together the brown sugar and fresh chopped herbs. Press 1-2 tablespoons of the herb and brown sugar mixture on top of each potato and drizzle with butter. Sprinkle with salt, pepper, and ground cinnamon.
  • Transfer to the oven and bake for 40 minutes. After 40 minutes, turn down the heat to 325 degrees F. Tent the sweet potatoes with a large sheet of aluminum foil and continue to bake for an additional 20-30 minutes, or until the potatoes are fully cooked and easily pierced with a fork or knife.
  • Best served immediately.


Transfer leftovers to an airtight container and keep stored in the refrigerator (they make fantastic leftovers!) for up to 3-4 days.
