Garlic Butter Scalloped Sweet Potatoes
Thinly sliced sweet potatoes in a wonderful garlic butter cream sauce and loaded with parmesan cheese. A delicious & decadent twist on classic scalloped potatoes.Â

I recently found an easy garlic butter scalloped sweet potatoes recipe on A Spicy Perspective that I couldn’t resist making. What’s better than tender sweet potatoes smothered in a garlic butter cream sauce? We all loved this delicious sweet potato recipe, and it paired well with some roasted chicken, roasted asparagus, and some crusty bread.
Garlic Butter Scalloped Sweet Potatoes
Ingredients:
- ¾ cup heavy cream
- ½ tsp cornstarch
- ¼ cup butter
- 3Â cloves of garlic, minced
- 3 small sprigs of fresh thyme, leaves removed & chopped
- Sea salt and freshly cracked pepper, to taste
- 1½ lbs sweet potatoes, peeled
- ¼ cup Parmesan, freshly grated
How to Make Garlic Butter Scalloped Sweet Potatoes
Preheat the oven to 350 degrees. Coat an 8-inch baking dish with cooking spray.
Mix the cream and cornstarch until thoroughly combined.
Pour the mixture into a small saucepan over medium-low heat along with the butter, garlic, thyme leaves, sea salt, and freshly cracked pepper, to taste. Cook just until the butter melts and the cream is warm, about 3-5 minutes. Remove from the heat and set aside until needed.
Using a mandolin or sharp knife, carefully slice the peeled potatoes into 1/8-inch thick rounds.
Fan out the potato rounds and arrange them in a decorative pattern in the baking dish.

Pour the warm cream/butter mixture evenly over the sweet potatoes.
Place in the oven and bake for 30-35 minutes.
Remove from the oven and sprinkle the top evenly with Parmesan cheese.
Return the baking dish to the oven to bake for 10 minutes, or until the cheese is melted.
Serve the sweet potatoes warm. Enjoy.

You have me at garlic butter and those melty cheesy topping! Just amazing!
Sweet potatoes and garlic had me hooked at the first glance 🙂
Have a good day, and stay safe. Diane
Very pretty presentation. Using sweet potatoes in the dish would have never crossed my mind but now I can’t wait to try it as we just bought a bag of them during our trip to Blue Ridge, GA
Delicious combination
Do you know why I love this so much? It’s because I practically gag this time of year seeing sweet potatoes with sugar and marshmallows. Yuck. Sweet potatoes are already sweet! Which is why they’re so good salty and garlicky! Obviously I don’t have to convince you!
I love that the flavors in this are super savory! Paired with the sweet potatoes, I’m sure this is awesome.
Un régal ce plat de pommes de terre ! Bonne fin de journée
I was looking for something different and tried this recipe. It was outstanding. It is a must try. My whole family loved it!!
Susan,
