Step‑by‑Step Instructions for Sweet Potato & Cranberry Gratin
Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This temperature is vital for achieving that golden, bubbling crust on your Sweet Potato & Cranberry Gratin. While the oven heats up, gather your baking dish and cooking utensils so everything is easily accessible for the next steps.
Step 2: Prepare the Sweet Potatoes
Peel and slice your sweet potatoes into thin rounds, aiming for even thickness to ensure uniform cooking. Bring a large pot of water to a boil, then carefully add the sweet potato slices and cook for 10-15 minutes until they are tender but not falling apart. Drain the potatoes and set them aside, ready for layering.
Step 3: First Layer of Sweet Potatoes
Grease a baking dish generously to prevent sticking. Layer half of the cooked sweet potato slices in the bottom of the dish, slightly overlapping them for an even spread. This base will hold the flavors of your Sweet Potato & Cranberry Gratin and add a beautiful foundation.
Step 4: Add the Cranberries
Sprinkle half of the fresh cranberries evenly over the first layer of sweet potatoes. The tartness of the cranberries will contrast beautifully with the sweetness of the potatoes. Spread the cranberries out so every bite of the gratin is bursting with flavor.
Step 5: Cream Mixture
In a medium mixing bowl, combine the heavy cream, brown sugar, cinnamon, salt, and pepper. Whisk the ingredients together until well-blended. Pour half of this luscious mixture evenly over the layered sweet potatoes and cranberries, adding a creamy richness that ties the dish together.
Step 6: Repeat the Layering
Layer the remaining sweet potato slices on top of the first layers, continuing the slightly overlapping pattern for consistency. Sprinkle the remaining cranberries over this second layer, ensuring each forkful of the Sweet Potato & Cranberry Gratin has a delightful burst of tartness.
Step 7: Final Cream Mixture
Pour the remaining cream mixture over the layers in the baking dish, allowing it to soak into the sweet potatoes and cranberries. Take a moment to poke the potatoes gently to help the cream spread evenly. This will create the perfect texture once baked.
Step 8: Topping
Finally, sprinkle a generous layer of Gruyère cheese over the top, followed by a coating of breadcrumbs for added crunch. This topping will form a beautifully golden crust, making your Sweet Potato & Cranberry Gratin irresistible.
Step 9: Bake the Gratin
Place the gratin in the preheated oven and bake for 30-35 minutes. As it bakes, watch for the top to become golden brown and bubbly, signaling that the gratin is perfectly cooked. The warm aromas will fill your kitchen, building excitement for the final dish.
Step 10: Cool and Serve
Once baked, remove the gratin from the oven and let it cool for a few minutes. This resting time allows the layers to set and makes serving easier. Finally, slice and serve this delightful Sweet Potato & Cranberry Gratin as a stunning side at your next holiday feast!

Sweet Potato & Cranberry Gratin Recipe FAQs
How do I choose the right sweet potatoes for this gratin?
When selecting sweet potatoes, look for ones that are firm, smooth, and free of dark spots or blemishes. They should have a vibrant orange color. If you spot any soft spots or dark patches, opt for different ones, as these may indicate spoilage.
What’s the best way to store leftover Sweet Potato & Cranberry Gratin?
Absolutely! Store your leftovers in an airtight container in the refrigerator for up to 3 days. This will help maintain the dish’s delightful creaminess and flavor. Be sure to let it cool completely before sealing the container to avoid excess moisture.
Can I freeze the Sweet Potato & Cranberry Gratin?
Yes, you can freeze this dish! I recommend freezing it unbaked for best results. Simply wrap it tightly in plastic wrap, then in aluminum foil, and it will stay good for up to 2 months. Make sure to label it with the date for easy tracking!
What should I do if my gratin seems too watery after baking?
If you find that your gratin is too watery, this can often happen if the sweet potatoes are overcooked before layering. To avoid this, ensure that they remain firm after boiling. If it does happen, simply bake it a bit longer to let some of the moisture evaporate, or add a bit more breadcrumb topping to absorb excess liquid.
Are there any dietary considerations I should keep in mind for this gratin?
Very! This Sweet Potato & Cranberry Gratin is vegetarian and can easily be made vegan by using coconut cream and dairy-free cheese options. Additionally, for gluten-free options, substitute regular breadcrumbs with gluten-free varieties. Always check the labels if you’re concerned about allergens, especially if serving to guests with dietary restrictions!
