Ingredients

Scale

Sweet Potatoes

  • 56 medium sweet potatoes, peeled and cut into thin medallions

Sauce

  • 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

Toppings

  • ¼ cup chopped pecans (or walnuts)
  • ½ cup mini marshmallows (plus extra if desired)

Instructions

  1. Preheat the oven: Set your oven to 400°F (204°C) to prepare for baking the sweet potatoes.
  2. Prepare sweet potatoes: Peel the sweet potatoes and slice them into thin medallions using a mandoline slicer for best results. Arrange the slices evenly in a baking dish.
  3. Make the sauce: In a small or medium saucepan on medium heat, combine the unsalted butter, brown sugar, water, ground cinnamon, ground cloves, ground nutmeg, and salt. Stir continuously until all the ingredients melt and form a smooth sauce.
  4. Apply initial sauce layer: Using a pastry brush, evenly coat about three-quarters of the sauce over the sweet potato medallions in the baking dish. Cover the dish tightly with foil.
  5. Bake covered: Place the covered baking dish in the preheated oven and bake for 45 to 50 minutes until the sweet potatoes are tender when pierced with a fork.
  6. Add toppings: Remove the foil and evenly spread the remaining quarter of the sauce on top of the sweet potatoes. Sprinkle chopped pecans and mini marshmallows over the surface.
  7. Broil for finishing touch: Switch the oven to the broil setting and place the dish back in the oven. Broil for 1 to 2 minutes until the marshmallows are toasted and golden. Watch closely to avoid burning.
  8. Cool and serve: Remove the dish from the oven and let it cool for 10 to 15 minutes to allow flavors to meld and to avoid burning. Serve warm and enjoy your scalloped sweet potatoes!

Notes

  • Using a mandoline slicer is highly recommended to achieve consistently thin, even sweet potato slices, which ensures uniform cooking.
  • If using salted butter instead of unsalted, omit the added ¼ teaspoon salt to avoid over-seasoning.
  • Feel free to add extra mini marshmallows on top for a sweeter, more decadent finish.
  • Keep a close eye during broiling as marshmallows can quickly burn.
