How to Make Scalloped Sweet Potatoes
Preheat your oven to 400 °F. This step ensures the sweet potatoes cook evenly, allowing them to caramelize beautifully as they bake.
Peel and slice the sweet potatoes into thin medallions. Aim for about ¼ inch thick to ensure they cook uniformly, resulting in tender goodness throughout.
Melt the unsalted butter, brown sugar, water, and spices together in a medium saucepan over medium heat. Stir gently until everything is combined and the mixture is bubbly, about 3-5 minutes.
Brush about ¾ of the sauce over the potato medallions in the baking dish, letting the sweet flavors seep in. Cover the dish with foil and bake for 45-50 minutes until they re fork-tender.
Uncover the dish, then drizzle the remaining sauce evenly over the medallions. Sprinkle with the chopped pecans and mini marshmallows for that delightful crunch and sweetness.
Broil the dish on high for 1-2 minutes, watching closely until the marshmallows toast to golden perfection. This quick step adds a divine texture and flavor to your scalloped sweet potatoes.
Cool for 10-15 minutes to allow the flavors to meld beautifully. Serve warm and enjoy the festivities at your table!
Optional: Garnish with a sprinkle of extra cinnamon for an aromatic touch.

These Scalloped Sweet Potatoes are a fantastic candidate for meal prep, making your busy weeknights a breeze! You can slice the sweet potatoes into medallions and prepare the sauce (melting the butter, brown sugar, spices, and water) up to 24 hours in advance. Simply store the medallions in an airtight container in the refrigerator to prevent browning, and keep the sauce in a separate container. When you re ready to cook, layer the medallions in a baking dish, brush on your sauce, cover, and bake as directed, adding the toppings and broiling just before serving. This way, you ll enjoy all the deliciousness of these scalloped sweet potatoes without the last-minute rush!

Tips for the Best Scalloped Sweet Potatoes

Watch the Broil: Broiling can burn quickly! Keep a close eye on the marshmallows as they toast to prevent them from turning too dark.
Rest Period: Let the scalloped sweet potatoes cool for 10-15 minutes after baking. This resting time helps the flavors to meld and the dish to set, making serving easier.
Adjust Sweetness: Feel free to modify the amount of brown sugar to suit your taste. Some prefer a sweeter experience, while others may favor a more balanced flavor.
