Description
Sweet Potato and Cranberry Gratin is a creamy, cozy, and festive 1-dish side that steals the show on holiday tables, layering tender sweet potatoes with tart cranberries, rich Gruyère cheese, and a crunchy buttered breadcrumb topping for a perfect balance of sweet and savory.
Ingredients
Scale
- 3 large sweet potatoes, peeled and thinly sliced
- 1½ cups fresh or frozen cranberries

- 2 cloves garlic, minced
- 1 tsp fresh thyme or ½ tsp dried thyme
- ½ tsp salt
- ¼ tsp black pepper
- 1½ cups shredded Gruyère cheese
- ½ cup breadcrumbs
- 2 tbsp melted butter
Instructions
- Preheat oven to 375°F (190°C) and lightly grease a baking dish.
- In a bowl, whisk heavy cream, garlic, thyme, salt, and black pepper.
- Layer half of the sweet potatoes evenly in the baking dish.
- Sprinkle half of the cranberries and half of the cheese over the potatoes.
- Repeat layers with remaining sweet potatoes, cranberries, and cheese.

Notes
- Make-ahead option: Assemble the gratin, cover, and refrigerate up to 1 day before baking; bake a few minutes longer if starting from cold.
- For a lighter version, substitute half-and-half or milk for part of the cream.
- Trim any overlong potato slices so they layer evenly.
- Garnish with fresh thyme or chopped parsley before serving for a pop of color.
