Best Scalloped Sweet Potatoes Recipe
Introduction
This recipe for Best Scalloped Sweet Potatoes combines tender, thinly sliced sweet potatoes with a rich, spiced butter sauce and a delightful topping of toasted marshmallows and pecans. It’s a perfect side dish for holiday dinners or any cozy meal that calls for a touch of sweetness and warmth.

Ingredients
- 5-6 medium sweet potatoes, peeled and cut into thin medallions
- ¼ cup unsalted butter
- ¼ cup brown sugar (light or dark)
- ½ cup water
- 1 teaspoon ground cinnamon
- 1 teaspoon ground cloves
- 1 teaspoon ground nutmeg
- ¼ teaspoon salt
- ¼ cup chopped pecans or walnuts
- ½ cup mini marshmallows
Instructions
- Step 1: Preheat your oven to 400°F (200°C). Peel the sweet potatoes and slice them into thin medallions using a mandoline slicer for best results, or a sharp knife if needed. Arrange the slices evenly in a baking dish.
- Step 2: In a small or medium saucepan over medium heat, combine the unsalted butter, brown sugar, water, ground cinnamon, ground cloves, ground nutmeg, and salt. Stir continuously as the ingredients melt and blend together into a smooth sauce.
- Step 3: Using a pastry brush, evenly coat about ¾ of the sauce mixture over the sweet potato medallions. Cover the baking dish tightly with foil and bake for 45 to 50 minutes, until the potatoes are tender.
- Step 4: Remove the baking dish from the oven and discard the foil. Brush the remaining ¼ of the sauce over the potatoes. Sprinkle the chopped pecans and mini marshmallows evenly over the top.
- Step 5: Set the oven to broil and return the dish to the oven. Broil for 1 to 2 minutes, watching carefully, until the marshmallows are toasted and golden. Remove from the oven and let the dish cool for 10 to 15 minutes before serving.
Tips & Variations
- Use a mandoline slicer to ensure uniform sweet potato slices for even cooking.
- Salted butter can be used instead of unsalted, but skip the additional salt in the sauce to balance flavors.
- Add a handful more marshmallows if you enjoy a sweeter topping and extra gooey texture.
- Swap pecans for walnuts if preferred, or omit nuts entirely for a nut-free dish.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover the dish with foil and warm in a 350°F (175°C) oven until heated through. Avoid microwaving to retain the best texture and flavor.
