Description

Creamy, cheesy layered sweet potatoes baked until tender and golden, perfect as a comforting side dish for any meal.


Ingredients

Sweet Potatoes

  • 3 large sweet potatoes, peeled and thinly sliced

Dairy

  • 1 cup heavy cream
  • 1 cup shredded cheese (Gruyère recommended for best flavor)

Seasonings

  • Salt, to taste
  • Black pepper, to taste


Instructions

  1. Prepare Sweet Potatoes: Peel the sweet potatoes and slice them thinly and evenly to ensure they cook through uniformly. Use a sharp knife or a mandoline for best results.
  2. Layer Ingredients: Arrange a layer of sweet potato slices in the bottom of a baking dish. Season lightly with salt and pepper. Repeat layering to build up the dish.
  3. Add Cream and Cheese: Pour the heavy cream evenly over the layered sweet potatoes, ensuring it seeps between the slices. Sprinkle the shredded cheese on top to create a golden, cheesy crust.
  4. Bake: Place the baking dish in a preheated oven at 375°F (190°C) and bake for 45 minutes, or until the sweet potatoes are tender and the cheese is golden and bubbling.

Notes

  • Gruyère cheese adds a rich, nutty flavor, but you can substitute with cheddar or mozzarella if preferred.
  • For a lighter option, use half-and-half instead of heavy cream, though the dish will be less rich.
  • Ensure sweet potato slices are of uniform thickness for even cooking.
  • Let the gratin rest for 5-10 minutes after baking to set before serving.
