Herb-Infused Scalloped Sweet Potatoes are a delightful twist on the classic comfort food, perfect for adding a touch of elegance to your table. With layers of tender sweet potatoes and rich, creamy sauce infused with fresh herbs, this dish is sure to impress.
Sweet Potatoes are the star, providing natural sweetness and a lovely color contrast. Butter adds richness, helping the potatoes bake to tender perfection. The heavy cream and whole milk form the base of the luscious sauce, carrying the flavors of garlic, sage, and thyme throughout the dish. A touch of salt and black pepper enhances the natural flavors, while Gruyère cheese and Parmesan cheese ensure a deliciously gooey finish.
These scalloped sweet potatoes make a wonderful side dish for roasted meats like chicken or pork. They also pair beautifully with a simple green salad, providing balance to the rich, creamy potatoes.
First, preheat your oven to 375°F (190°C) and generously butter a large baking dish. This sets the stage for your potatoes to bake evenly without sticking. In a saucepan, combine the heavy cream, milk, garlic, sage, thyme, salt, and pepper and bring this to a simmer over medium heat. Once it's heated through, remove it from the heat; allowing the flavors to meld without boiling.
Now, layer half of your thinly sliced sweet potatoes in the prepared dish. Overlapping them slightly ensures even cooking. Pour half of the creamy herb mixture over this layer, followed by sprinkling half of the Gruyère and Parmesan cheeses. Repeat with the remaining potatoes, cream mixture, and cheeses. Cover the dish with foil to trap the steam, helping the potatoes become tender. Bake for 45 minutes.
After 45 minutes, carefully remove the foil and continue baking for another 20 minutes. This allows the top to develop a beautiful golden crust. Once done, let it sit for a few minutes before serving, allowing the sauce to thicken slightly.
