How to Make Sweet Potato Cranberry Gratin
-
Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish to prepare for your festive creation. This ensures your gratin bakes evenly and doesn’t stick.
-
Slice the sweet potatoes into thin rounds, about 1/8 inch thick. Use a knife or mandoline to create even slices for a creamy, consistent texture throughout.
-
Combine heavy cream, salt, pepper, and chopped thyme in a medium saucepan. Warm over medium heat until heated through but not boiling, allowing the flavors to meld beautifully.
-
Layer half of the sweet potato slices in the greased baking dish, followed by half the cranberries and half the cheese. This layering helps create a delightful balance of flavors in each bite.
-
Repeat the layering process with the remaining sweet potatoes, cranberries, and cheese. Make sure everything is evenly distributed for a perfect, cohesive dish.
-
Top the gratin with panko breadcrumbs, ensuring they cover the entire surface, and drizzle melted butter over everything to achieve a crispy, golden topping.
-
Bake for 45 minutes, or until the top is golden brown and bubbling. Let it cool slightly before serving to allow the flavors to settle and make it easier to serve.
Optional: Garnish with fresh thyme for an extra pop of flavor and color.

Expert Tips for Sweet Potato Cranberry Gratin

- Cheese Layers: Consider adding an additional layer of cheese between the sweet potatoes and cranberries for extra richness and flavor depth in the Sweet Potato Cranberry Gratin.

- Butter Brilliance: Don’t skimp on drizzling melted butter over the panko topping to achieve that sought-after crispy, golden crust; it makes all the difference!
How to Store and Freeze Sweet Potato Cranberry Gratin

Sweet Potato Cranberry Gratin Recipe FAQs
What kind of sweet potatoes should I choose for the gratin?
Absolutely! For the best flavor and texture in your Sweet Potato Cranberry Gratin, select firm, unblemished sweet potatoes. Look for those with smooth skins and avoid any with dark spots or blemishes, as these can indicate spoilage.
How should I store leftover Sweet Potato Cranberry Gratin?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it in the oven at 350°F (175°C) for about 20-30 minutes until heated through. This will help maintain the creamy texture and prevent it from drying out.
Can I freeze Sweet Potato Cranberry Gratin?
Certainly! You can freeze unbaked Sweet Potato Cranberry Gratin for up to 2 months. Assemble the layers in your baking dish, cover tightly with plastic wrap and then foil, ensuring it’s well-protected from freezer burn. When you’re ready to bake, you can cook it directly from frozen, just adding an extra 15-20 minutes to the baking time.
What should I do if my gratin is too watery?
If you find that your Sweet Potato Cranberry Gratin has turned out too watery, it’s often due to excess moisture in the sweet potatoes or cranberries. To troubleshoot, ensure you’re slicing the sweet potatoes evenly and not overcrowding the layers. You can also try cooking the gratin a bit longer, allowing extra moisture to evaporate. If you’re using frozen cranberries, make sure to drain any excess liquid before adding them to your layers.
Are there any dietary considerations for this recipe?
Very! While this Sweet Potato Cranberry Gratin is not specifically dietary-themed, if you’re concerned about allergies, be aware that it includes dairy from the heavy cream and cheese. For a dairy-free variant, consider using almond milk or coconut milk and a dairy-free cheese alternative. Always check the labels if you’re serving guests with allergies.
