Step‑by‑Step Instructions for Sweet Potato & Cranberry Gratin Step 1: Preheat the Oven Start by preheating your oven to 375°F (190°C). This ensures a perfectly baked Sweet Potato & Cranberry Gratin. While the oven warms up, gather your baking dish and grease it lightly with cooking spray or butter to prevent sticking. Step 2: Prepare the Sweet Potatoes Peel and slice the sweet potatoes into thin rounds for even cooking. In a large pot, add these slices along with enough salted water to cover them. Bring it to a boil and let it simmer for 10 to 15 minutes, or until the sweet potatoes are tender when pierced with a fork. Drain the water and set the sweet potatoes aside. Step 3: Layer the First Ingredients Begin layering your Sweet Potato & Cranberry Gratin in the greased baking dish. Arrange half of the boiled sweet potato slices at the bottom, overlapping them slightly. This technique helps distribute the flavors evenly while creating a visually appealing base for the dish. Step 4: Add Cranberries Next, take half of the fresh cranberries and sprinkle them generously over the first layer of sweet potatoes. The tartness of the cranberries will contrast beautifully with the sweet potatoes, adding a burst of flavor to each bite. Step 5: Mix the Cream Mixture In a mixing bowl, combine the heavy cream, brown sugar, cinnamon, salt, and pepper. Whisk these ingredients together until the sugar dissolves. Pour half of this creamy mixture uniformly over the layered sweet potatoes and cranberries, ensuring every layer gets a touch of creaminess. Step 6: Repeat Layering Now it’s time to repeat the layering process. Add the remaining sweet potato slices on top of the first layer, followed by the rest of the cranberries. Pour the remaining cream mixture over this second layer, ensuring it soaks down through the sweet potatoes for rich flavor throughout. Step 7: Add the Toppings Sprinkle the Gruyère cheese evenly over the top of the layered gratin, followed by a generous dusting of breadcrumbs. The cheese will melt down deliciously, while the breadcrumbs will create a delightful crispy texture, ensuring a pleasing contrast when baked. Step 8: Bake to Perfection Place your completed Sweet Potato & Cranberry Gratin in the preheated oven. Bake for 30 to 35 minutes or until the top is beautifully golden brown and bubbly. This step is crucial for achieving that perfect mix of creamy texture and crunchy topping. Step 9: Cool and Serve Once baked, remove the gratin from the oven and allow it to cool for about 10 minutes. This time helps the layers set together, making it easier to serve. Gather your loved ones and present this festive Sweet Potato & Cranberry Gratin at your table, reveling in the compliments that are sure to follow!

Sweet Potato & Cranberry Gratin Recipe FAQs How do I choose ripe sweet potatoes? Absolutely! Look for sweet potatoes that are firm, smooth, and free of dark spots or blemishes. The skin should be a vibrant color, indicating freshness. Avoid any that are sprouting or have soft spots, as these may not cook well. How should I store leftovers of Sweet Potato & Cranberry Gratin? Store any leftover Sweet Potato & Cranberry Gratin in an airtight container in the fridge for up to 3 days.
