Preheat oven to 400°F.
Peel sweet potatoes, cut them into thin medallions and arrange them in your baking dish.
Place a small or medium saucepan on the stovetop. Add unsalted butter, brown sugar, water, spices and salt. Turn heat to medium and stir ingredients as they melt together.
¼ cup unsalted butter, ¼ cup brown sugar, ½ cup water, 1 teaspoon ground cinnamon, 1 teaspoon ground cloves, 1 teaspoon ground nutmeg, ¼ teaspoon salt
Once the mixture is fully melted, use a pastry brush to evenly distribute ¾ of your sauce onto sweet potato medallions. Cover baking dish with foil and bake for 45-50 minutes.
Remove baking dish from the oven and take foil off. Distribute the remaining ¼ of your sauce mixture onto the potato medallions. Sprinkle with chopped pecans and mini marshmallows.
¼ cup chopped pecans, ½ cup mini marshmallows
Place baking dish back into the oven and turn it to the broil setting. Broil for 1-2 minutes to toast the marshmallows. Keep a close eye on the dish as your broil, it won't take long!
Remove from the oven and allow to cool for 10-15 minutes. Serve and enjoy!
