Ingredients

Scale

Vegetables & Fruit

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

Dairy & Cheese

  • 1 cup heavy cream
  • 1 cup shredded Gruyère cheese

Other Ingredients

  • 1/2 cup breadcrumbs
  • 1/4 cup brown sugar
  • 1 teaspoon cinnamon
  • Salt and pepper to taste

Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the gratin.
  2. Boil Sweet Potatoes: In a large pot, boil the peeled and sliced sweet potatoes until tender, about 10 to 15 minutes; this ensures they cook evenly in the gratin.
  3. Layer Sweet Potatoes: Drain the sweet potatoes and arrange half of them in a greased baking dish, forming the first layer.
  4. Add Cranberries: Sprinkle half of the fresh cranberries evenly over the sweet potato layer to add tartness and color.
  5. Mix Cream Mixture: In a medium bowl, combine heavy cream, brown sugar, cinnamon, salt, and pepper; mix well to blend the flavors.
  6. Pour Cream Mixture: Pour half of the cream mixture over the layered sweet potatoes and cranberries to infuse moisture and sweetness.
  7. Repeat Layers: Repeat the layering with the remaining sweet potatoes, cranberries, and cream mixture, ensuring an even build.
  8. Add Toppings: Sprinkle the shredded Gruyère cheese and breadcrumbs evenly over the top for a rich, crispy crust.
  9. Bake the Gratin: Bake in the preheated oven for 30 to 35 minutes, or until the top is golden brown and bubbly, signaling it’s ready to serve.

Notes

  • For extra flavor, you can add a pinch of nutmeg to the cream mixture.
  • If you prefer a creamier texture, use half-and-half instead of heavy cream.
  • Ensure sweet potatoes are sliced evenly for uniform cooking.
  • Use fresh cranberries for the best tartness; frozen cranberries can be substituted but may release more moisture.
  • Let the gratin rest for 5 minutes before serving to set the layers.
