Ingredients
  

  • 4.0 medium sweet potatoes, peeled and thinly sliced
  • 4.0 tablespoons unsalted butter, softened
  • 2.0 cloves garlic, minced
  • 2.0 teaspoons fresh rosemary, chopped
  • 2.0 teaspoons fresh thyme, chopped
  • 1.0 teaspoon salt
  • 0.5 teaspoon black pepper
  • 0.5 teaspoon smoked paprika
  • 1.0 cup heavy cream
  • 1.0 cup grated Gruyère cheese
  • 0.5 cup breadcrumbs
  • 0.0 none Fresh parsley, chopped for garnish

Instructions
 

  • Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with butter.
  • In a medium bowl, combine the softened butter, minced garlic, rosemary, thyme, salt, black pepper, and smoked paprika. Mix well until all the herbs are evenly incorporated into the butter.
  • Begin layering the sweet potatoes in the greased baking dish. Make a layer of sweet potato slices, then spread a thin layer of the herb butter over them. Continue this process until all sweet potatoes are used, finishing with a layer of sweet potatoes on top.
  • Pour the heavy cream evenly over the layered sweet potatoes, ensuring it seeps down through the layers. Then, sprinkle the grated Gruyère cheese generously across the top.
  • Evenly distribute the breadcrumbs over the cheese layer for a crispy topping.
  • Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Then, remove the foil and bake for an additional 20-25 minutes, or until the sweet potatoes are tender and the top is golden brown and bubbly.
  • Once baked, remove from the oven and let it sit for about 10 minutes. Sprinkle fresh parsley over the top for a pop of color and freshness before serving.
