What You’ll Need

Gather these items for your Southern Maple Sweet Potato Casserole:

3 cups roasted sweet potatoes, mashed
1/2 cup maple syrup
1/4 cup brown sugar
1/2 cup raisins
1 teaspoon cinnamon
1/2 teaspoon nutmeg
1/2 cup mini marshmallows
1/2 cup chopped pecans
2 tablespoons melted vegan butter

Feel free to substitute raisins with dried cranberries for a citrusy zing, or use regular butter if you’re not strictly vegan.

Step-by-Step Instructions

Preheat the oven to 350°F (175°C).
In a large mixing bowl, combine the mashed sweet potatoes, maple syrup, brown sugar, raisins, cinnamon, and nutmeg. Mix until everything is smooth and well combined.
Fold in the mini marshmallows gently to keep them intact.
Transfer the mixture to a greased casserole dish, smoothing the top with a spatula.
In another bowl, mix the chopped pecans with melted vegan butter and sprinkle this over the sweet potato mixture.
Bake for 30-35 minutes, or until the casserole is heated through and the topping is golden brown.
Let it cool slightly before serving to allow the flavors to set.

Best Ways to Enjoy It

This Southern Maple Sweet Potato Casserole can be served hot as a side dish or enjoyed on its own as a comforting main option. Pair it with roasted vegetables or a fresh green salad to complement the sweetness, or serve it alongside a savory protein like maple-glazed ham or grilled chicken. It’s also fantastic the next day, warmed up, and makes for a unique brunch option.

Keeping Leftovers Fresh

To properly store your Southern Maple Sweet Potato Casserole, allow it to cool completely before transferring it to an airtight container. It can last in the refrigerator for up to 5 days. If you want to keep it longer, consider freezing it! It can be frozen for up to three months—just thaw in the fridge overnight before reheating.

Helpful Cooking Tips

For the best results with your casserole, ensure that the sweet potatoes are well-roasted before mashing; this step intensifies their flavor. Don’t rush the mixing stage; take your time to blend the ingredients thoroughly, as this ensures an even distribution of flavors. If you’re a fan of texture, consider adding a sprinkle of chopped walnuts along with the pecans for an added crunch.

Spicy pecan topping: Add a pinch of cayenne or smoked paprika to the pecans for a spicy kick.
