  2. In a mixing bowl, toss sliced sweet potatoes with cinnamon, salt, and pepper until evenly coated.
  3. In a saucepan, melt butter, add flour to form a roux, then whisk in heavy cream until thickened. Stir in cranberries and brown sugar.
  4. Layer one-third of sweet potatoes in the baking dish, top with one-third of the creamy sauce, and repeat until all ingredients are used.
  5. Cover the dish with foil and bake for 45-50 minutes, until sweet potatoes are tender.

  7. Let the gratin rest for 10-15 minutes before serving.
