How to Make Sweet Potato & Cranberry Gratin

Now that you have all your ingredients ready, let’s dive into the fun part—making this delicious Sweet Potato & Cranberry Gratin! Follow these simple steps, and you’ll have a dish that’s sure to impress.

Step 1: Preheat the Oven

First things first, preheat your oven to 375°F (190°C). Preheating is crucial because it ensures even cooking. You want that gratin to bubble and brown perfectly, and starting with a hot oven is key!

Step 2: Boil the Sweet Potatoes

Next, peel and slice your sweet potatoes. Then, place them in a large pot of boiling water. Boil them for about 10-15 minutes until they’re tender. This step is essential because it softens the potatoes, making them easier to layer and ensuring they cook evenly in the oven.

Step 3: Layer the Sweet Potatoes

Once the sweet potatoes are tender, drain them and start layering half of the slices in a greased baking dish. Make sure to overlap them slightly for a beautiful presentation. This creates a solid base for your gratin.

Step 4: Add the Cranberries

Now, sprinkle half of the fresh cranberries over the sweet potato layer. These tart little gems are the secret to balancing the sweetness of the potatoes. They’ll burst with flavor as they bake, adding a delightful contrast!

Step 5: Prepare the Cream Mixture

In a separate bowl, mix together the heavy cream, brown sugar, cinnamon, salt, and pepper. This creamy mixture is what brings everything together. Pour half of it over the layered sweet potatoes and cranberries, ensuring every bite is packed with flavor.

Step 6: Repeat the Layers

Now it’s time to repeat the layering process! Add the remaining sweet potatoes, followed by the rest of the cranberries. Pour the remaining cream mixture on top. This repetition ensures a balanced dish with layers of flavor in every bite.

Step 7: Top with Cheese and Breadcrumbs

For the final touch, sprinkle shredded Gruyère cheese and breadcrumbs over the top. This topping is essential for that crispy, golden finish. The cheese melts beautifully, while the breadcrumbs add a satisfying crunch!

Step 8: Bake the Gratin

Finally, place your dish in the preheated oven and bake for 30-35 minutes. Keep an eye on it! You’ll know it’s done when the top is golden brown and bubbly. Let it cool for a few minutes before serving, and watch as your family gathers around the table, eager to dig in!

Tips for Success

Use a mandoline slicer for even sweet potato slices, ensuring uniform cooking.
Don’t skip the preheating step; it’s vital for achieving that perfect golden crust.
Feel free to mix in other spices like nutmeg for added warmth.

Let the gratin rest for a few minutes after baking; it helps set the layers.
Experiment with different cheeses for unique flavor profiles!

Equipment Needed

Baking Dish: A 9×13 inch dish works perfectly. You can also use a cast-iron skillet for a rustic look.

Pot: A large pot for boiling sweet potatoes. Any sturdy pot will do.
Mixing Bowl: For combining the cream mixture. A medium-sized bowl is ideal.
Mandoline Slicer: Optional, but it helps achieve even sweet potato slices.

Measuring Cups and Spoons: Essential for accurate ingredient measurements.

Variations

Vegan Version: Swap heavy cream for coconut cream and use a plant-based cheese to make this dish vegan-friendly.
Spicy Kick: Add a pinch of cayenne pepper or red pepper flakes to the cream mixture for a subtle heat that complements the sweetness.

Nutty Flavor: Incorporate chopped pecans or walnuts into the layers for added crunch and a nutty flavor.
Herb Infusion: Mix in fresh herbs like thyme or rosemary into the cream mixture for an aromatic twist.
Cheese Swap: Experiment with different cheeses like feta or goat cheese for a tangy flavor profile.

Serving Suggestions

Pair the Sweet Potato & Cranberry Gratin with roasted turkey or glazed ham for a festive feast.
Serve alongside a fresh green salad to balance the richness of the gratin.
For drinks, consider a light white wine or sparkling cider to complement the flavors.
