Ingredients for Recipe Candied Sweet Potatoes Marshmallows

Sweet potatoes, marshmallows, and pecans create this golden, gooey holiday classic.

The sweet potatoes are the foundation—choose firm, medium-sized yams with smooth skin (the deep orange kind, not the white-fleshed variety). Whole Foods and Trader Joe’s carry excellent organic options. The pecans should be fresh; stale nuts taste bitter. I prefer Georgia pecans from Costco for their buttery crunch. For the marshmallows, Jet-Puffed mini marshmallows melt most evenly.

No brown sugar? Granulated sugar plus 1 tbsp molasses per cup works in a pinch. Swap pecans for walnuts or almonds if preferred. The cinnamon can be pumpkin pie spice for extra warmth. Heavy cream not on hand? Evaporated milk (1:1 ratio) or full-fat coconut milk (for a dairy-free version) both work. Orange juice can be replaced with pineapple juice for a tropical twist.

Assemble and refrigerate up to 24 hours ahead. Leftovers keep 3-4 days in the fridge (reheat covered with foil). The casserole freezes beautifully for 2-3 months—thaw overnight before baking. Pecans toast best fresh, so add them just before serving if prepping ahead.

Step-by-Step Instructions for Candied Sweet Potatoes with Marshmallows

This method ensures a perfectly caramelized topping with tender sweet potatoes beneath.

Step 1: Prepare and Parboil the Sweet Potatoes

Peel the 4 lb Sweet Potatoes and cut them into 1-inch cubes. Place them in a large pot and cover with cold water by about 1 inch. Add 0.5 tsp Salt to the water to enhance the natural sweetness of the potatoes.

Bring to a boil over high heat, then reduce to a simmer. Cook for 8-10 minutes until the cubes are just fork-tender but still hold their shape. Drain immediately and transfer to a 9×13-inch baking dish—this prevents them from continuing to cook and turning mushy.

Step 2: Create the Spiced Butter Sauce

In a saucepan over medium heat, melt the 0.5 cup Unsalted Butter. Stir in the 1 cup Light Brown Sugar, 1.5 tsp Ground Cinnamon, and 0.25 tsp Ground Nutmeg. Cook for 2-3 minutes, stirring constantly, until the mixture thickens slightly and the sugar dissolves completely.

Remove from heat and stir in the 1 tsp Vanilla Extract, 0.25 cup Orange Juice, and 0.25 cup Heavy Cream. The orange juice adds a bright contrast to the rich sweetness, while the cream creates a velvety texture. Pour this sauce evenly over the parboiled sweet potatoes in the baking dish.

Step 3: Thicken and Top the Casserole

Sprinkle the 2 tbsp All-Purpose Flour evenly over the sauce-covered sweet potatoes. This will thicken the sauce as it bakes, creating a luscious, syrupy consistency rather than a watery mixture. Gently fold the flour into the sauce with a spatula to distribute it evenly.

Scatter the 1 cup Pecans over the top, pressing them lightly into the sauce so they adhere. Then arrange the 10 oz Mini Marshmallows in an even layer, covering the entire surface. The marshmallows should be touching each other slightly—they’ll expand and merge as they toast.

Step 4: Bake to Golden Perfection

Preheat your oven to 375°F. Bake the casserole uncovered on the middle rack for 20-25 minutes. You’re looking for the marshmallows to turn a deep golden brown with some areas slightly darker—this indicates a perfect caramelized topping.

If the marshmallows brown too quickly but the sauce beneath isn’t bubbly, tent the dish loosely with foil for the remaining time. The casserole is done when the edges are bubbling and the marshmallows have achieved that ideal toasted finish. Let it rest for 5 minutes before serving to allow the sauce to set slightly.

Regional Styles of This recipe candied sweet potatoes marshmallows

Southern Style

In the South, we often add 1/2 cup bourbon to the sauce for depth. The alcohol cooks off, leaving a rich, caramel-like flavor that pairs beautifully with the sweet potatoes. I use Maker’s Mark for its smooth, slightly sweet profile. 🔥

Midwestern Tradition

Midwestern versions frequently include 1/2 cup crushed pineapple in the sauce. This adds a tangy brightness that cuts through the richness. The pineapple also helps tenderize the sweet potatoes during baking.

New England Twist

New England cooks often swap pecans for 1 cup chopped walnuts and add 1/4 tsp maple syrup to the sauce. This creates a more autumnal flavor profile that’s popular during Thanksgiving. I love how the maple enhances the natural sweetness.

Texas Variation

Everything’s bigger in Texas, including the marshmallow layer—some use up to 16 oz for an extra-gooey topping. They also add 1/2 tsp cayenne pepper to the sauce for a subtle kick that balances the sweetness. 🌶️

California Light

West Coast versions often reduce the sugar by half and add 1/2 cup dried cranberries for tartness. The cranberries plump up during baking, adding pops of color and a pleasant contrast to the sweet potatoes.
