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 temperature is essential for achieving a perfectly baked Sweet Potato & Cranberry Gratin with a crispy top. While the oven warms up, gather your other ingredients and equipment, including a large pot, a baking dish, and a mixing bowl, to streamline your cooking process.
Step 2: Prepare the Sweet Potatoes
Peel and slice the sweet potatoes into evenly-sized rounds to ensure they cook uniformly. Place them in a large pot filled with water and bring it to a boil. Let the sweet potatoes simmer for about 10-15 minutes, or until they’re tender but not falling apart. You’ll know they’re ready when you can easily pierce them with a fork.
Step 3: Layer the First Sweet Potato Layer
Once the sweet potatoes are cooked, drain them thoroughly and transfer half of them into a greased baking dish. Arrange the slices in an overlapping pattern for a delightful presentation. This base layer will provide the foundation for the Sweet Potato & Cranberry Gratin’s beautiful flavors.
Step 4: Add the Cranberries
Sprinkle half of the fresh cranberries evenly over the first layer of sweet potatoes. Their tartness will complement the sweetness of the potatoes beautifully. Make sure to distribute them well, so each bite of the gratin features that delightful burst of flavor from the cranberries.
Step 5: Mix the Cream Mixture
In a mixing bowl, combine the heavy cream (or coconut cream for a vegan option), brown sugar, cinnamon, salt, and pepper. Whisk the ingredients together until the mixture is smooth and well-blended. Pour half of this creamy mixture evenly over the sweet potato and cranberry layers to start building that rich flavor profile.
Step 6: Layer the Remaining Ingredients
Repeat the layering process by adding the rest of the sweet potatoes on top of the first layers, making sure to slightly overlap them again. Then, sprinkle the remaining cranberries over the second sweet potato layer. Finish by pouring the rest of the cream mixture over these layers to lock in moisture and flavor.
Step 7: Add Cheese and Breadcrumbs
Sprinkle a generous layer of shredded Gruyère cheese on top of the gratin for extra richness. Next, add breadcrumbs over the cheese to create a deliciously crispy topping. The combination of creamy layers beneath with a crunchy finish will make your Sweet Potato & Cranberry Gratin irresistible.
Step 8: Bake to Perfection
Place the baking dish in your preheated oven and bake for 30-35 minutes. Keep an eye on the gratin during the last few minutes of baking; it’s ready when the top is golden brown and bubbly. A beautiful, crispy crust will signal that your Sweet Potato & Cranberry Gratin is now ready to dazzle your guests!

Sweet Potato & Cranberry Gratin Recipe FAQs
How do I choose ripe sweet potatoes?
Absolutely! Look for sweet potatoes that are firm, smooth, and free of dark spots or blemishes. The skin should have a vibrant color—whether orange or purple—and avoid those with soft areas. Storing them in a cool, dark place works best to maintain their freshness.
How should I store leftover Sweet Potato & Cranberry Gratin?
To keep your gratin fresh, store leftovers in an airtight container in the fridge for up to 3 days. Be sure to allow it to cool completely before sealing for best texture retention. When reheating, place it in a preheated oven at 350°F (175°C) for about 20-25 minutes.
Can Sweet Potato & Cranberry Gratin be frozen?
Yes! You can freeze this gratin for up to 2 months. Make sure to let it cool completely before sealing it tightly in a freezer-safe container. To reheat, thaw it overnight in the refrigerator and then warm in a 350°F (175°C) oven until heated through. Adding a splash of cream can help revive its creamy texture.
What should I do if my gratin is watery?
If you find that your gratin is too watery, it might be due to the sweet potatoes releasing excess moisture. For next time, ensure the sweet potatoes are well-drained after boiling. You can also add a bit more cheese or breadcrumbs to help absorb some of that liquid. Letting it bake longer could help create a beautifully crispy top while evaporating some of that moisture.
Are there vegan substitutes I can use in the Sweet Potato & Cranberry Gratin?
Very much! To create a vegan version, substitute heavy cream with coconut cream and omit the cheese or replace it with a plant-based cheese alternative. For the breadcrumbs, you can use crushed gluten-free crackers or ground nuts to maintain a deliciously crunchy topping while keeping it plant-based and gluten-free.
Can I make this gratin ahead of time?
Absolutely! You can assemble the Sweet Potato & Cranberry Gratin a day in advance. Simply layer all your ingredients, cover tightly, and store it in the fridge until you’re ready to bake it. This saves time and allows the flavors to meld beautifully, ensuring a delightful dish for your gathering.
