Ingredients Equipment Method Notes

Ingredients
  

  • 2 large sweet potatoes peeled and cubed
  • 1 cup apple cider
  • 2 tablespoons olive oil divided
  • 1 teaspoon fresh sage chopped
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup shredded Gruyère cheese
  • 1/2 cup bread crumbs preferably rustic or panko
  • 1 tablespoon butter melted

Equipment

  • Chef's Knife
  • Cutting board
  • Mixing bowls
  • Baking Dish
  • Spoon or spatula
  • Oven

Method
 

  1. Preheat your oven to 400°F (200°C) and line a baking dish with parchment paper or lightly grease it.
  2. Peel and cut the sweet potatoes into 1-inch cubes. Toss them in a bowl with 1 tablespoon of olive oil, chopped sage, salt, and pepper until evenly coated.
  3. Spread the sweet potato cubes in a single layer on a baking sheet. Roast in the oven for about 25-30 minutes until they are golden around the edges and tender when poked with a fork.
  4. In the meantime, warm the apple cider in a small saucepan over medium heat until it just begins to bubble, allowing it to reduce slightly and intensify the flavor.
  5. Once the sweet potatoes are roasted, transfer them to a large mixing bowl and gently mash them with a fork or potato masher. Drizzle the warm apple cider over the mash and fold gently to combine and keep the mixture moist.
  6. Pour the sweet potato mixture into your prepared baking dish, spreading it out evenly with a spatula.
  7. In a small bowl, mix grated Gruyère cheese, bread crumbs, and melted butter. Sprinkle this topping evenly over the sweet potato layer.
  8. Bake the casserole uncovered for about 15-20 minutes, or until the topping is golden brown and crispy, and the casserole is bubbly around the edges.
  9. Remove the casserole from the oven and let it rest for 5 minutes before serving. You will see a beautiful golden crust with tender, flavorful sweet potato underneath.
  10. Scoop out portions and enjoy this hearty, autumn-inspired dish that combines sweet, savory, and herbaceous flavors.

Notes

For an extra touch of flavor, sprinkle some additional fresh sage on top before serving.
