This Sweet Potato & Cranberry Gratin is a festive, comforting dish perfect for holiday gatherings. Layers of tender boiled sweet potatoes and tart fresh cranberries are drenched in a sweetly spiced cream mixture, topped with melted Gruyère cheese and crispy breadcrumbs, then baked to a golden, bubbly perfection.

Ingredients

Sweet Potato & Fruit

  • 2 pounds sweet potatoes, peeled and sliced
  • 1 cup fresh cranberries

Cream Mixture

  • 1 cup heavy cream
  • 1/4 cup brown sugar
  • 1 teaspoon cinnamon
  • Salt and pepper to taste

Topping

  • 1 cup shredded Gruyère cheese
  • 1/2 cup breadcrumbs

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the gratin.
  2. Boil Sweet Potatoes: Place the peeled and sliced sweet potatoes into a large pot of boiling water and cook until they are tender, about 10 to 15 minutes. Drain them well to remove excess water.
  3. First Layer: Grease a baking dish and arrange half of the boiled sweet potato slices evenly on the bottom.
  4. Add Cranberries: Evenly sprinkle half of the fresh cranberries over the sweet potato layer to add a tart contrast.
  5. Mix Cream Mixture: In a mixing bowl, combine heavy cream, brown sugar, cinnamon, salt, and pepper. Stir well to ensure the sugar and spices are evenly distributed.
  6. Pour Cream Mixture: Pour half of the cream mixture over the layered sweet potatoes and cranberries, allowing the flavors to meld.
  7. Repeat Layers: Layer the remaining sweet potatoes and cranberries on top, then pour over the rest of the cream mixture to complete the assembly.
  8. Top with Cheese and Breadcrumbs: Sprinkle shredded Gruyère cheese and breadcrumbs evenly over the top to create a flavorful, crispy crust when baked.
  9. Bake: Place the baking dish in the preheated oven and bake for 30 to 35 minutes, or until the top is golden brown and bubbly, indicating the gratin is cooked through.
  10. Cool and Serve: Remove from the oven and let the gratin rest for a few minutes before serving to allow it to set and enhance the flavors.

Notes

  • For a nuttier flavor, substitute Gruyère with Comté or sharp cheddar cheese.
  • Breadcrumbs can be toasted with a little butter beforehand for extra crispiness.
  • Adjust the amount of brown sugar to suit your desired sweetness level.
  • This dish can be prepared a few hours ahead and refrigerated before baking; just increase the baking time slightly if baking from cold.
  • For a dairy-free option, substitute heavy cream with coconut cream and use a dairy-free cheese alternative.
