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 your Sweet Potato & Cranberry Gratin bakes evenly and develops a beautifully golden top. While the oven warms up, gather your ingredients and greased baking dish, preparing to create layers of deliciousness.

Step 2: Prepare the Sweet Potatoes
Peel and slice the sweet potatoes into thin rounds. In a large pot, bring water to a boil and add the sweet potato slices. Boil them for about 10-15 minutes, or until they are just tender but not falling apart. Drain the potatoes and let them cool slightly before layering.

Step 3: Layer the First Half of Sweet Potatoes
Once the sweet potatoes are cooled, arrange half of the slices in your greased baking dish. Overlap them slightly to create a solid base. This layer will form the heart of your Sweet Potato & Cranberry Gratin, so ensure it’s even and beautifully laid out.

Step 4: Add the Cranberries
Sprinkle half of the fresh cranberries over the first layer of sweet potatoes. As you do this, ensure the cranberries are evenly distributed to balance the sweetness of the potatoes. The tartness of the cranberries will beautifully complement the rich layers to come.

Step 5: Mix the Creamy Topping
In a mixing bowl, combine heavy cream (or coconut cream for a vegan option), brown sugar, cinnamon, salt, and pepper. Whisk the mixture until well blended. Pour half of this creamy blend evenly over the layered sweet potatoes and cranberries, enveloping them in delicious flavor.

Step 6: Layer the Remaining Ingredients
Repeat the process by layering the remaining sweet potato slices on top of the first layers, followed by the rest of the cranberries. Pour the remaining cream mixture over this final layer, ensuring every slice is coated and ready to bake into a creamy, flavorful dish.

Step 7: Add the Finishing Touches
Now it’s time to elevate your Sweet Potato & Cranberry Gratin with a generous topping of shredded Gruyère cheese and breadcrumbs. This will create a delectable crust as it bakes, bringing that desired crunch that complements the soft layers underneath.

Step 8: Bake the Gratin
Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is bubbling and golden brown. The cheese should be melted and toasty, indicating that your Sweet Potato & Cranberry Gratin is ready to be taken out and enjoyed. Let it cool for a few minutes before serving.

Expert Tips for Sweet Potato & Cranberry Gratin

Preboiling Secret: Ensure even cooking by boiling sweet potatoes briefly before layering; this prevents any hard bits from sneaking into your gratin.

Watch the Toppings: Keep an eye on the baking time. The gratin should be golden, but if it browns too quickly, tent it with aluminum foil to prevent burning.
