Sweet Potato & Cranberry Gratin Ingredients
For the Gratin

• Cinnamon – Provides warm spice notes that beautifully complement sweet and savory flavors.
• Salt and Pepper – Essential seasonings for enhancing flavor depth.

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 will ensure that it’s perfectly hot for baking your Sweet Potato & Cranberry Gratin. As the oven heats up, gather your ingredients and prepare your baking dish by greasing it lightly with butter or cooking spray to prevent sticking.
Step 2: Prepare the Sweet Potatoes
Peel the sweet potatoes and slice them into even discs, about 1/4 inch thick. Bring a large pot of salted water to a boil, then add the sweet potato slices. Boil them for about 10-15 minutes until tender; they should be easily pierced with a fork but not mushy. Once done, drain the sweet potatoes well.
Step 3: Layer the First Ingredients
Carefully layer half of the cooked sweet potato slices in the greased baking dish, covering the bottom evenly. This forms a lovely base for your Sweet Potato & Cranberry Gratin. Next, sprinkle half of the fresh cranberries over the top, ensuring they’re spread out to complement the sweetness of the potatoes.
Step 4: Mix the Cream Mixture
In a mixing bowl, combine the heavy cream, brown sugar, cinnamon, and a generous pinch of salt and pepper. Whisk until smooth, allowing the flavors to meld beautifully. Pour half of this creamy mixture evenly over the layered sweet potatoes and cranberries, letting it seep into the gaps.
Step 5: Repeat the Layering
Now, repeat the layering process with the remaining sweet potato slices and the rest of the cranberries. This second layer will enrich the flavors of your Sweet Potato & Cranberry Gratin. Pour the remaining cream mixture over this second layer, ensuring everyone gets a taste of that creamy goodness.
Step 6: Add Cheese and Breadcrumbs
Sprinkle a generous layer of shredded Gruyère cheese over the top of your gratin, followed by a handful of breadcrumbs. This will create a deliciously crispy topping when baked. Make sure to cover the surface evenly, which will help achieve that golden brown crust we all cherish.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 30-35 minutes. Stay close and watch as the top transforms into a bubbly, golden brown paradise. The aroma of sweet potatoes mingling with cranberries will surely tempt your taste buds during this exciting wait.
Step 8: Cool Before Serving
Once baked, carefully remove the Sweet Potato & Cranberry Gratin from the oven and let it cool for about 5-10 minutes. This short cooling time allows the layers to set slightly, making it easier to serve. Enjoy the warm embrace of flavors as you dish out this festive delight to your guests.
