Step-by-Step Instructions
- Preheat your oven to 375°F (190°C) and prepare your baking dish by greasing it.
- Peel and slice sweet potatoes into ¼-inch thick rounds. Boil them in water for 10-15 minutes until fork-tender, then drain.
- Layer half of the cooked sweet potatoes in the greased baking dish, slightly overlapping them.
- Evenly sprinkle half of the fresh cranberries over the sweet potatoes.
- In a bowl, whisk together heavy cream, brown sugar, cinnamon, salt, and pepper. Pour half over the layered sweet potatoes and cranberries.
- Repeat with the remaining sweet potatoes and cranberries, then pour the remaining cream sauce over the layers.
- Top with shredded Gruyère cheese and breadcrumbs.
- Bake for 30-35 minutes until the top is bubbly and golden brown, then allow to cool briefly before serving.

Notes
For a vegan version, use coconut cream instead of heavy cream. Assemble the gratin ahead of time and refrigerate for convenience.
