How to Make Sweet Potato & Cranberry Gratin

Preheat the oven to 375°F (190°C). This helps achieve that golden, bubbly crust you’re looking for. Prepping your oven beforehand sets the perfect stage for this delightful dish!
-
Boil the peeled and sliced sweet potatoes in a pot of water for 10-15 minutes until tender, then drain. They should be fork-tender but not mushy—aim for that creamy texture!
-
Layer half of the sweet potato slices in a greased baking dish, slightly overlapping for even cooking. This creates a solid base that will soak up all those delicious flavors!
-
Distribute half of the fresh cranberries over the base layer. These will add a lovely tartness that complements the sweet potatoes beautifully—don’t skimp on them!
-
Mix heavy cream, brown sugar, cinnamon, salt, and pepper in a bowl; pour half of this mixture over the layers. This creamy blend ties everything together and enriches the layers with flavor.
-
Repeat layering with the remaining sweet potatoes and cranberries; top with the remaining cream mixture for that extra indulgence. This double-layering ensures every bite is packed with deliciousness!
-
Sprinkle the shredded Gruyère cheese and breadcrumbs on top. This will create that irresistible crispy topping when baked—it’s the crowning glory!

Expert Tips for Sweet Potato & Cranberry Gratin

Creamy Consistency: When mixing the heavy cream, avoid over-mixing; you want a creamy blend without air bubbles, ensuring a smooth gratin.

Perfect Browning: Keep an eye on the baking time towards the end; if the top browns too quickly, cover loosely with aluminum foil to prevent burning.
-
Make-Ahead Option: Assemble the Sweet Potato & Cranberry Gratin a day in advance, cover, and refrigerate. Just bake it before serving for a stress-free holiday!
-
Taste Testing: Adjust the balance of sweetness with brown sugar to suit your preferences—experimenting can lead to your perfect version!

Sweet Potato & Cranberry Gratin Recipe FAQs
What type of sweet potatoes should I use for the gratin?
Absolutely! Look for sweet potatoes that are firm with smooth skin and no dark spots. The best variety for gratin is the orange-fleshed ones, often labeled as “yams” at the grocery store. These provide that creamy texture and natural sweetness that enhances your dish.
How long can I store leftovers of Sweet Potato & Cranberry Gratin?
You can store leftovers in an airtight container in the fridge for up to 3 days. Just make sure to let it cool completely before sealing it up to maintain its freshness. When you’re ready to enjoy it again, simply reheat in the oven for a lovely second try!
Can I freeze Sweet Potato & Cranberry Gratin?
Yes, you can! To freeze, let the gratin cool, then wrap it tightly in plastic wrap and aluminum foil or place it in a freezer-safe container. It can be frozen for up to 2 months. When you’re ready to enjoy it, thaw overnight in the refrigerator and bake it at 350°F (175°C) for 25-30 minutes until warmed through.
What if my gratin doesn’t cook through properly?
If you find your gratin is not cooked through, don’t worry! Double-check that the sweet potatoes were sliced evenly and boiled long enough. If it’s not bubbling or getting a golden color, cover it with aluminum foil and continue baking until it’s fully heated. Just ensure you check the internal temperature reaches at least 165°F (74°C) for your safety.
Are there any allergens in this recipe?
Very! This recipe contains dairy from the heavy cream and cheese, and some folks may be allergic to sweet potatoes. For dietary restrictions, I recommend using coconut cream instead of heavy cream and a dairy-free cheese alternative. You can easily avoid gluten by using gluten-free breadcrumbs.
Can I prepare the Sweet Potato & Cranberry Gratin in advance?
Definitely! You can assemble the gratin the day before, cover it tightly, and refrigerate until you’re ready to bake. This not only saves you time on the day of your gathering but also allows the flavors to meld beautifully. Just remember to add the crispy topping just before baking for the best texture!
