How to Make Sweet Potato & Cranberry Gratin
Creating Sweet Potato and Cranberry Gratin at home is a simple yet rewarding endeavor. With just a few straightforward steps, you can craft a dish that’s as beautiful as it is delicious. Let’s dive into the process and discover how to bring this recipe to life.
Step 1: Preparing the Oven and Ingredients
Begin by preheating your oven to 375°F (190°C). This ensures that your gratin bakes evenly and achieves that perfect golden-brown top.
Next, gather all your ingredients together so you are ready to start assembling your dish. You’ll need:
- 4 large sweet potatoes, sliced
- 1 cup fresh cranberries
- 1 cup Gruyère cheese, grated
- 1 cup breadcrumbs
- 1 cup heavy cream
- 2 tablespoons butter
- Salt and pepper to taste
Step 2: Layering the Ingredients
In a greased baking dish, it’s time to start building your layers. First, arrange a layer of sweet potato slices at the bottom, allowing them to overlap slightly. The bright orange flesh of the sweet potatoes will invite everyone to the table, adding a visual appeal.
Now, sprinkle a generous layer of fresh cranberries over the sweet potatoes. The tartness of the cranberries will provide a beautiful contrast to the sweetness of the potatoes, enriching every bite.
Following that, add a layer of grated Gruyère cheese. This cheese melts beautifully, adding a rich and creamy texture that’s simply irresistible. Don’t forget to season the layer with a pinch of salt and a dash of pepper to enhance the flavors.
Step 3: Repeat the Layers
Continue the process by repeating the layers—sweet potatoes, cranberries, cheese, and seasoning—until all the ingredients have been used up. Don’t rush; make sure each layer is well-distributed. When you finish, the dish should be filled with colorful layers that will be the star of your meal.
Step 4: Adding the Cream
Once the final layer of cheese is added, it’s time to pour heavy cream over the top. The cream seeps down through the layers, creating a luscious sauce that envelops the vegetables as they cook. This step is crucial for ensuring that your gratin is not only flavorful but also tender and creamy.
Step 5: Preparing the Topping
Before popping the dish into the oven, melt the butter and mix it with the breadcrumbs in a small bowl. This mixture will create a crispy topping that contrasts beautifully with the soft layers below. Sprinkle it evenly over the top of your gratin.
Step 6: Baking to Perfection
Place your baking dish in the preheated oven and bake for about 45 minutes. As it bakes, your kitchen will fill with an incredible aroma as the sweet potatoes become tender and the top turns a golden brown. Once it’s ready, allow the gratin to cool slightly before serving, as this will enhance the flavors and make it easier to cut into portions.

Storage Tips for Sweet Potato & Cranberry Gratin
If you find yourself with leftovers (though they may be rare), storing your Sweet Potato and Cranberry Gratin properly ensures that it stays fresh for your next meal. Here are some tips for best storage practices:
- Refrigerate: Store in an airtight container for 3–4 days at 40°F (4°C).
- Freeze: For longer-term storage, freeze the gratin for up to 2 months. Make sure to wrap it tightly in plastic wrap before placing it in a freezer bag to prevent freezer burn.
