The Art of Sweet Potato Cranberry Gratin
Great gratin depends on evenly sliced sweet potatoes, nestled with pockets of tart cranberries, and baked until tender and bubbling. The topping forms a crisp, caramelized layer that contrasts perfectly with the creamy base. A touch of citrus brightens the overall dish.
Step-by-Step Instructions
1. Preheat & Prepare
Preheat your oven to 375°F (190°C).
Grease a baking dish with a little butter.
2. Layer the Sweet Potatoes
Arrange a layer of sliced sweet potatoes in the bottom of the dish.
3. Add Cranberries & Spices
Sprinkle cranberries over the sweet potatoes.
Mix brown sugar, cinnamon, nutmeg, salt, and optional orange zest together; sprinkle over the layers.
4. Add Butter
Dot the top with small pieces of butter as you build layers.
5. Repeat Layers
Continue layering sweet potatoes, cranberries, and spice mixture until the dish is filled.
6. Prepare the Topping
In a small bowl, mix panko breadcrumbs (or chopped pecans), brown sugar, melted butter, and a pinch of cinnamon.
7. Add Topping
Spread the crumb mixture evenly over the sweet potato and cranberry layers.
8. Bake
Cover with foil and bake 30–35 minutes.
Remove foil and bake an additional 10–20 minutes, until sweet potatoes are tender and topping is golden brown.
9. Cool & Serve
Let the gratin rest for a few minutes before serving warm.
