Step‑by‑Step Instructions for Sweet Potato & Cranberry Gratin

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step is crucial as a properly heated oven ensures even baking, which is vital for achieving that golden, bubbly top on your Sweet Potato & Cranberry Gratin.

Step 2: Prepare the Sweet Potatoes
While the oven is preheating, peel and slice your sweet potatoes evenly. Place them in a large pot of boiling water and cook for 10-15 minutes until they are just tender when pierced with a fork. This softening process enhances the gratin’s creamy texture later. Drain the sweet potatoes and set them aside.

Step 3: Layer the Ingredients
In a greased baking dish, start layering half of the cooked sweet potato slices. Overlap them slightly for an inviting presentation. This layer will serve as a lovely foundation for the gratin, showcasing the vibrant colors and flavors of the sweet potatoes and cranberries.

Step 4: Add the Cranberries
Sprinkle half of the fresh cranberries over the layer of sweet potatoes, distributing them evenly. The tartness of the cranberries will contrast beautifully with the sweet, creamy potatoes, creating a delightful flavor balance in your Sweet Potato & Cranberry Gratin.

Step 5: Prepare the Cream Mixture
In a mixing bowl, combine heavy cream, brown sugar, cinnamon, salt, and pepper. Whisk these ingredients together until well-blended and smooth. This rich mixture will pour over the layered ingredients, adding creaminess and warmth to your dish.

Step 6: Repeat the Layering
Layer the remaining sweet potato slices on top of the first layer, followed by the rest of the cranberries. Ensure even coverage so that every bite of the Sweet Potato & Cranberry Gratin bursts with flavor. Then, pour the remaining cream mixture over this layer, ensuring it seeps into the filling.

Step 7: Add the Topping
Sprinkle the shredded Gruyère cheese generously over the top of the gratin, followed by a layer of breadcrumbs. This combination will create a delightful crispy topping that complements the creamy layers beneath beautifully.

Step 8: Bake the Gratin
Place the baking dish in your preheated oven and bake for 30-35 minutes. Keep an eye on the gratin; it’s ready when the top is golden brown and the edges are bubbling gently. This step is crucial for achieving that mouthwatering finish.

Step 9: Cool and Serve
Once baked, remove the Sweet Potato & Cranberry Gratin from the oven and allow it to cool for a few minutes. This resting time helps the dish set, making it easier to serve. Enjoy this beautifully layered, comforting dish as a festive side during your holiday gatherings.
