Description

A classic Thanksgiving side dish featuring thinly sliced sweet potatoes baked in a buttery, spiced brown sugar sauce, topped with crunchy pecans and toasted mini marshmallows for a sweet and savory delight.


Ingredients

Scale

Sweet Potatoes

  • 5-6 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


Instructions

  1. Preheat Oven: Preheat your oven to 400°F to prepare for baking the sweet potatoes.
  2. Prepare Potatoes: Peel the sweet potatoes and slice them into thin medallions using a mandoline slicer or knife. Arrange the slices evenly in a baking dish.
  3. Make Sauce: In a small or medium saucepan over medium heat, melt together unsalted butter, brown sugar, water, ground cinnamon, ground cloves, ground nutmeg, and salt, stirring until fully combined and smooth.
  4. Coat Potatoes: Using a pastry brush, evenly spread about three-quarters of the prepared sauce over the sweet potato slices in the baking dish.
  5. Bake Covered: Cover the baking dish with foil and bake in the preheated oven for 45 to 50 minutes, until the potatoes are tender.
  6. Add Toppings: Remove the foil and spread the remaining sauce over the potatoes. Sprinkle chopped pecans and mini marshmallows evenly on top.
  7. Broil: Return the baking dish to the oven and switch to the broil setting. Broil for 1 to 2 minutes, watching carefully until the marshmallows toast and turn golden brown.
  8. Cool and Serve: Remove from oven and let cool for 10 to 15 minutes before serving to allow the dish to set.

Notes

  • For ease and uniform slices, use a mandoline slicer to cut sweet potatoes thinly.
  • If using salted butter instead of unsalted, omit the additional ¼ teaspoon salt in the sauce to avoid oversalting.
  • Add extra mini marshmallows if you prefer a sweeter topping.
