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 ensures that your Sweet Potato & Cranberry Gratin will bake evenly and develop a beautiful golden crust. Setting the right temperature is a crucial first step to achieve that perfect bubbling finish, so hang tight while the oven warms up, and prepare your ingredients.
Step 2: Prepare the Sweet Potatoes
Next, peel and slice your sweet potatoes into thin rounds, approximately 1/4 inch thick for even cooking. In a large pot filled with water, bring the sweet potatoes to a boil and let them cook for 10-15 minutes, or until they’re just tender but not falling apart. You’ll know they’re ready when you can easily pierce them with a fork.
Step 3: Assemble the First Layer
Once drained, turn on your oven again and prepare a greased baking dish. Layer half of the cooked sweet potatoes in the bottom, overlapping them slightly for a beautiful look. This first layer will provide a sturdy base for your Sweet Potato & Cranberry Gratin, combining sweetness and softness that sets the tone for the dish.
Step 4: Add Cranberries
Sprinkle half of the fresh cranberries evenly over your first layer of sweet potatoes. These will create a delightful tart contrast to the creamy sweet potatoes and add a festive pop of color. Make sure the cranberries are well-distributed to ensure every bite is bursting with flavor.
Step 5: Mix the Cream Mixture
In a mixing bowl, combine the heavy cream, brown sugar, cinnamon, salt, and pepper. Whisk the ingredients together until fully combined—this will create a creamy, sweet sauce that binds the flavors of your Sweet Potato & Cranberry Gratin. Pour half of this mixture over the first layer in the baking dish, evenly coating the sweet potatoes and cranberries.
Step 6: Repeat Layering
Now, it’s time to create the second layer! Place the remaining sweet potatoes on top of the cranberries, again overlapping them slightly. This layer adds depth and volume to your gratin, enhancing the overall texture. Follow with the remaining cranberries, ensuring they’re dispersed well to maximize flavor throughout the dish.
Step 7: Final Cream Layer
Pour the rest of the creamy mixture over the second layer you’ve just built. Make sure it reaches all the edges of the dish; this will help prevent the gratin from drying out while it bakes and will ensure a luscious consistency. It’s this final touch that brings everything together in a delightful harmony of flavors.
Step 8: Add Toppings
To finish off your Sweet Potato & Cranberry Gratin, sprinkle the shredded Gruyère cheese and breadcrumbs generously over the top. The cheese will melt and create a lovely rich layer, while the breadcrumbs will add a delightful crunch when baked. This crunchy topping is what will make this dish feel extra special.
Step 9: Bake to Perfection
Place the gratin in your preheated oven and bake for 30-35 minutes. You’ll know it’s ready when the top is golden brown and bubbly, and the edges are starting to caramelize. Keep an eye on it toward the end to prevent the breadcrumbs from burning, ensuring a beautiful presentation for your feast.
Step 10: Cool and Serve
Once baked to perfection, remove the gratin from the oven and allow it to cool slightly for about 10 minutes. This resting time will help the dish set, making it easier to serve. Your Sweet Potato & Cranberry Gratin is now ready to dazzle at your holiday table, bursting with warmth and flavor in every bite!
