- Parmesan Cheese: A generous amount of freshly grated Parmesan provides a salty, umami-rich, and nutty flavor, creating a delightful cheesy crust and creamy interior.

Crafting Your Perfect Sweet Potato Au Gratin: A Step-by-Step Guide
Creating this magnificent sweet potato au gratin is simpler than you might imagine, yielding impressive results with just a few key steps. Follow these instructions carefully to ensure a dish that’s rich, creamy, and beautifully tender:
- Prepare the Cream Topping First: Begin by making your luscious cream sauce. In a small saucepan over medium heat, or in a microwave-safe bowl, combine the heavy cream, cornstarch, butter, minced garlic, chopped fresh thyme, salt, and pepper. Whisk these ingredients together thoroughly and frequently until the butter has just melted, ensuring everything is well combined and the cornstarch is fully dissolved. This crucial step should be completed first. Having the mixture ready allows you to immediately pour it over each sweet potato slice as you arrange them, preventing the delicate potato slices from browning due to oxidation.
- Expertly Peel and Slice the Sweet Potatoes: The key to a tender, delicate texture in your au gratin lies in the slicing. Peel the sweet potatoes one by one, and then, using a mandoline slicer or a very sharp knife, slice each potato into exceptionally thin, uniform rounds, about 1/8-inch thick. Precision here is paramount; these thin slices are essential for achieving that classic scalloped potato texture where each layer cooks evenly and becomes incredibly tender after baking.
- Thoughtful Arrangement and Coating: As you thinly slice each sweet potato, immediately arrange the rounds in an aesthetically pleasing pattern in your chosen baking dish (a 9×13 inch dish is ideal). The pattern is entirely up to your creative preference – perhaps overlapping rows or a circular design. Crucially, after arranging a layer of slices, pour a small amount of your melted garlic herb butter and cream mixture over each thin sweet potato slice. Continue this process, layering and coating, before slicing the next potato. This continuous coating helps to slow down the oxidation process, keeping your sweet potato slices from discoloring, and also ensures every layer is infused with flavor.
- Bake Your Casserole to Golden Perfection: Once all the sweet potato layers are arranged and drenched in the creamy mixture, it’s time to bake. Preheat your oven to a precise 400 degrees Fahrenheit (200°C). Place the baking dish in the preheated oven and bake for approximately 30 minutes. At this point, the sweet potatoes should be tender when pierced with a fork. Next, remove the dish from the oven, sprinkle generously with the remaining Parmesan cheese, and return it to bake for a few more minutes. Continue baking until the cheese is beautifully melted, bubbly, and the top layers of your scalloped sweet potatoes achieve a magnificent golden-brown hue. Serve warm and enjoy the exquisite flavors and textures!

Frequently Asked Questions About Scalloped Sweet Potatoes
Here are answers to some common questions about this delectable Garlic Butter Scalloped Sweet Potato recipe, helping you perfect your dish and explore its versatility.
Can this scalloped potato recipe be made with other varieties of potatoes?
Absolutely! While sweet potatoes lend a unique flavor and vibrant color, this recipe is incredibly versatile. You can certainly substitute them with other potato varieties. Feel free to use white or purple sweet potatoes, classic russet potatoes, or even delicate new potatoes. The cooking instructions and method for your scalloped potatoes will remain essentially the same, allowing you to adapt the dish to your preference or what you have on hand.
Is this Scalloped Sweet Potatoes recipe gluten-free?
Yes, it is! You’ll be delighted to know that this delicious scalloped sweet potatoes recipe is naturally gluten-free. Sweet potatoes themselves are naturally gluten-free, and all the other ingredients in this recipe – heavy cream, butter, garlic, herbs, cornstarch, and Parmesan cheese – are also free from gluten. This makes it a wonderful option for those with gluten sensitivities or dietary restrictions, ensuring everyone can enjoy its creamy goodness.
Is this recipe low-carb or ketogenic?
No, this recipe is not considered low-carb or ketogenic. Sweet potatoes are a starchy vegetable and inherently contain a significant amount of carbohydrates. Therefore, this dish is not suitable for a low-carb or ketogenic diet. However, if you are looking for a **grain-free** option, you can achieve this by substituting the cornstarch with arrowroot powder. While it won’t make the dish low-carb, it will cater to those avoiding grains.
Can I make a dairy-free variation?
Absolutely, a dairy-free version of this rich dish is entirely possible! For a delicious Vegan Garlic “Butter” Sweet Potato Au Gratin, you can make a few simple substitutions. Replace the heavy cream with full-fat coconut milk (the thick, creamy kind from a can, not the beverage type) and use a high-quality vegan butter instead of regular butter. You will also need to omit the Parmesan cheese. The resulting dish will still be incredibly flavorful and creamy, offering a wonderful plant-based alternative.
P.S. – If you happen to prepare this as a vegan scalloped sweet potato casserole, and you opt to use arrowroot powder instead of cornstarch, then this recipe also becomes suitable for a paleo diet!
Is there a low-fat version of this Sweet Potato Au Gratin?
Achieving a truly low-fat version while retaining the signature luxurious, silky texture of au gratin is challenging, as cream and butter are integral to its character. However, if you wish to significantly reduce the fat content, you could omit both the heavy cream and butter entirely. Instead, brush the thinly sliced sweet potatoes with a little olive oil and then season them generously with garlic and herbs. While the scalloped potatoes will not possess the same opulent, silky mouthfeel, they will still bake up soft, tender, and wonderfully herbaceous, offering a healthier, lighter alternative.
Can I freeze this recipe?
Given the generous amount of cream and butter in these scalloped sweet potatoes, freezing is not recommended. Dairy-heavy dishes, especially those with thin potato slices, tend to separate and become grainy or watery upon thawing and reheating. The texture will likely be compromised, and the delicious creaminess may be lost. For optimal taste and texture, it’s best to enjoy this dish fresh from the oven.
Can I make this recipe ahead?
Yes, this recipe is an excellent candidate for make-ahead preparation, which is fantastic for busy holiday cooking! You can fully assemble and bake these scalloped sweet potatoes up to 3 days in advance. Once baked, allow them to cool completely, then cover the dish tightly with foil or plastic wrap and refrigerate. When you’re ready to serve, simply reheat the uncovered casserole in a 350-degree Fahrenheit (175°C) oven for 20 minutes or more, until it’s heated through and bubbly. If desired, you can sprinkle a little extra Parmesan cheese on top before reheating for a fresh, cheesy crust.

Sweet Potatoes Au Gratin Recipe
Ingredients
- 3 pounds sweet potatoes
- 1 1/4 cup heavy cream
- 6 tablespoons butter
- 6 cloves garlic, minced
- 2 tablespoons fresh thyme, chopped
- 1 teaspoon cornstarch
- 1/3 cup Parmesan cheese
- Salt and pepper to taste
Instructions
-
Preheat your oven to 400 degrees F (200°C). Prepare your fresh thyme by pulling the leaves off the stems and roughly chopping them. Discard the stems.
-
In a small bowl or pot, whisk together the heavy cream and cornstarch until smooth. Add the butter, minced garlic, chopped thyme, 1 1/4 teaspoon salt, and 1/2 teaspoon pepper. Gently heat this mixture over the stovetop on medium-low heat, or in the microwave, just until the butter has completely melted. Do not boil. Remove from heat and whisk once more to ensure everything is perfectly combined.
-
Peel each sweet potato one by one. Using a mandoline or a very sharp knife, carefully slice the potatoes into uniform, very thin rounds, approximately 1/8-inch thick. This thinness is crucial for a tender, evenly cooked dish. Arrange the first layer of sliced potatoes in a 9×13-inch baking dish, fanning them out in an attractive pattern.
-
After arranging each layer of sweet potato slices, pour a small amount of the prepared cream mixture evenly over them. This step is important to prevent the potato slices from browning due to air exposure while you continue to peel and slice the remaining potatoes.
-
Repeat the layering process until all the sweet potatoes are sliced and beautifully arranged in the baking dish, with each layer coated in the creamy sauce. Finally, pour any remaining cream mixture over the very top layer, ensuring every slice is generously bathed in the rich sauce.
-
Bake the casserole in the preheated oven for 30 minutes. After 30 minutes, remove the dish, sprinkle the Parmesan cheese generously over the sweet potatoes. Return the dish to the oven and bake for another 10 minutes, or until the cheese is melted, bubbly, and forms a golden-brown crust. Serve warm and savor every comforting bite!
