Ingredients

Scale

Sweet Potatoes

  • 2 large sweet potatoes (about pounds), peeled and thinly sliced ( inch thick)

Sauce

  • 1 cup heavy cream
  • ½ cup packed brown sugar
  • 3 tablespoons butter
  • 1 teaspoon cinnamon
  • ½ teaspoon nutmeg
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract

Topping (Optional)

  • ½ cup mini marshmallows

Instructions

  1. Preheat and prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray to prevent sticking.
  2. Slice the sweet potatoes: Peel the sweet potatoes and slice them thinly to about ⅛-inch thickness. This ensures even, tender cooking. Arrange the slices in the prepared baking dish, layering them slightly overlapped for consistency.
  3. Make the brown sugar sauce: In a medium saucepan over medium heat, melt the butter. Stir in the brown sugar, heavy cream, cinnamon, nutmeg, salt, and vanilla extract. Whisk continuously until the mixture is smooth and the sugar is fully dissolved, creating a rich, fragrant sauce.
  4. Assemble the casserole: Pour the warm brown sugar sauce evenly over the layered sweet potatoes. Use a spatula to gently move the slices so each one gets coated with the luscious sauce.
  5. Bake covered: Cover the baking dish tightly with foil. Place it in the oven and bake for 35 minutes. This allows the sweet potatoes to soften while absorbing the creamy sauce.
  6. Bake uncovered: Remove the foil and continue baking for an additional 20 to 25 minutes. The sweet potatoes should become fork-tender, and the sauce should bubble and thicken.
  7. Optional marshmallow topping: If desired, sprinkle mini marshmallows evenly over the top during the last 5 minutes of baking. Bake until the marshmallows are golden brown and gooey, adding a delightful sweetness and texture contrast.
  8. Serve: Let the scalloped sweet potatoes cool slightly before serving. Optionally garnish with a light sprinkle of cinnamon or fresh herbs to enhance the presentation and flavor.

Notes

  • For a less sweet version, reduce the brown sugar or omit the marshmallows.
  • Use a mandoline slicer for uniform sweet potato slices and faster prep.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
  • To make this dish dairy-free, substitute heavy cream with coconut cream and use vegan butter.
  • Ensure the sweet potatoes are sliced thinly so they cook evenly and become tender.
