How to Make Sweet Potato & Cranberry Gratin: A Must-Try Festive Recipe!
Step 1: Preheat and Prepare Sweet Potatoes
Start by preheating your oven to 375°F (190°C). While the oven gets ready, place the peeled and sliced sweet potatoes into a large pot of boiling water. Cook them until they’re just tender, about 10 to 15 minutes. This step ensures they’ll be silky soft inside when baked, while still holding their shape beautifully in the gratin.
Step 2: Layer the First Half
Once drained, begin layering half of your sweet potato slices evenly in a greased baking dish. Then, sprinkle half of the fresh cranberries over the potatoes to introduce that zingy tartness that elevates the entire dish.
Step 3: Mix and Pour Cream Mixture
In a bowl, combine the heavy cream, brown sugar, cinnamon, salt, and pepper. This flavorful cream mixture will bring richness, sweetness, and just the right hint of spice to your gratin. Pour half of this mixture over the layered sweet potatoes and cranberries, letting it soak into every nook.
Step 4: Repeat the Layers
Next, repeat the layering process with the remaining sweet potatoes and cranberries. Pour over the rest of the cream mixture to ensure every bite is moist and flavorful. This layering creates a beautiful mosaic of color and flavor that’s truly irresistible.
Step 5: Add Toppings and Bake
Now, sprinkle the shredded Gruyère cheese generously over the top, followed by the breadcrumbs. This final touch will bake into a golden, bubbling, crispy crust that is simply mouthwatering. Place your dish in the preheated oven and bake for 30 to 35 minutes until the top is perfectly browned and the gratin is bubbling around the edges.
Step 6: Rest and Serve
Before serving, let your Sweet Potato & Cranberry Gratin rest for a few minutes. This brief cool-down helps everything settle and lets the flavors meld beautifully. Then, scoop into warm plates and prepare for compliments to pour in!

Garnishes
A sprinkle of fresh thyme or rosemary leaves adds an aromatic herbal note that complements the sweet and tart flavors perfectly. For a little extra crunch and holiday cheer, toss on some toasted pecans or walnuts just before serving.
Side Dishes
This gratin is quite the star on its own, but it pairs wonderfully with savory mains like roasted turkey, glazed ham, or even a simple mushroom wellington. A crisp green salad with a tangy vinaigrette can provide a refreshing balance to the richness of the dish.
Creative Ways to Present
For an elegant holiday table, bake the gratin in individual ramekins so each guest gets a personal portion that looks stunning plated. Alternatively, layer it in festive ceramic dishes to bring warmth and coziness right to your dinner spread.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover your Sweet Potato & Cranberry Gratin tightly with plastic wrap or transfer to an airtight container. It will keep beautifully in the refrigerator for up to 3 days without losing its charming texture or flavor.
Freezing
If you want to prepare this festive treat ahead of time, feel free to freeze it before baking. Wrap it securely and freeze for up to one month. Thaw it overnight in the fridge when ready, then bake as directed for a freshly baked taste.
Reheating
Reheat leftovers in a preheated oven at 350°F (175°C) for about 15-20 minutes until warmed through and the topping is crispy again. Avoid microwaving if you want to keep that delightful gratin crust intact.
