Scalloped Sweet Potatoes
Scalloped sweet potatoes are a comforting casserole featuring thinly sliced sweet potatoes baked in a creamy, herb-infused sauce with a golden cheesy crust. This rich, balanced side dish fits festive, holiday, or weekday meals alike.
Ingredients
- 2 ½ pounds sweet potatoes
- 3 tablespoons unsalted butter
- 1 small yellow onion finely chopped
- 3 cloves garlic minced
- 2 tablespoons all-purpose flour
- 1 ½ cups whole milk
- ¾ cup heavy cream
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon ground nutmeg
- 1 teaspoon chopped fresh thyme
- ½ cup grated Parmesan cheese
Instructions
- Preheat oven to 375°F. Grease a 9x13 inch baking dish with butter or nonstick spray.
- Peel and thinly slice the sweet potatoes to about ⅛ inch thick using a mandoline slicer or sharp knife. Set aside.
- In a large saucepan over medium heat, melt the butter. Add chopped onion and cook until soft and fragrant, about 4 to 5 minutes.
- Add minced garlic and cook for 1 minute more. Sprinkle in flour, stirring constantly for 1 to 2 minutes to form a roux.
- Slowly pour in milk and cream, whisking to create a smooth mixture. Add salt, black pepper, nutmeg, and thyme.
- Simmer the sauce over medium heat for about 5 minutes, stirring occasionally, until slightly thickened.
- Arrange one layer of sweet potatoes in the prepared baking dish and pour a portion of the sauce over the layer, spreading evenly.
- Repeat layering sweet potatoes and sauce until all are used, ending with sauce on top.
- Sprinkle grated Parmesan cheese evenly over the surface.
- Cover dish with foil and bake for 45 minutes. Remove foil and bake for an additional 20 to 25 minutes, or until the top is golden and potatoes are tender.
- Let cool for 10 minutes before serving for best texture and flavor.
