How to Make Sweet Potato & Cranberry Gratin
Preheat your oven to 375 °F (190 °C) to create a consistent cooking temperature for the gratin. This step is crucial for even cooking and golden toppings!
Peel and slice the sweet potatoes, then place them in a pot of water. Boil them for 10-15 minutes or until they are tender enough to be easily pierced with a fork.
Drain the sweet potatoes and layer half of the slices in a greased baking dish, slightly overlapping them for an appealing look.
Sprinkle half of the fresh cranberries over the sweet potato layer to infuse that delightful tartness enhancing the overall flavor.
Mix heavy cream, brown sugar, cinnamon, salt, and pepper in a bowl. Pour half of this creamy mixture over your layered ingredients.
Repeat layering with the remaining sweet potatoes and cranberries, and then pour the rest of the cream mixture on top. This will ensure every bite is flavorful!
Top with Gruy ¨re cheese and sprinkle breadcrumbs generously over the surface for that perfectly crispy finish.
Bake in the preheated oven for 30-35 minutes or until the top is golden brown and bubbling. This creates a beautiful contrast of textures!
Cool for a few minutes before serving, allowing the flavors to settle and making it easier to cut into portions.
Optional: Garnish with fresh herbs like thyme or parsley for an added pop of color and flavor.
