The Art of Sweet Potato Cranberry Gratin
This gratin depends on evenly sliced sweet potatoes and well-distributed cranberries. Seasoning brings warmth, while a crumble topping adds texture. Baking until the topping is golden and the potatoes are tender gives the perfect creamy interior and crisp exterior contrast.
Step-by-Step Instructions
1. Preheat & Prepare
Preheat your oven to 375°F (190°C).
Lightly grease a baking dish.
2. Layer Sweet Potatoes
Arrange a layer of sweet potato slices across the bottom of the dish.
3. Add Cranberries & Seasoning
Scatter cranberries over the sweet potatoes.
Sprinkle with brown sugar, cinnamon, nutmeg, salt, and optional orange zest or juice.
4. Continue Layering
Repeat layers of sweet potatoes, cranberries, and seasoning until all ingredients are used.
5. Prepare the Topping
In a small bowl, combine panko crumbs or pecans, brown sugar, melted butter, and optional cinnamon.
Mix until evenly coated.
6. Add Topping
Sprinkle the crumb mixture evenly over the layered sweet potatoes and cranberries.
7. Bake
Cover with foil and bake 30–35 minutes.
Remove foil and bake an additional 10–20 minutes, until potatoes are tender and the topping is golden brown.
8. Cool & Serve
Let the gratin rest for a few minutes before serving warm.
Tips for Best Results
