Creamy buttery sweet potato casserole is the ultimate Thanksgiving side dish that’ll have your guests asking for seconds. This silky, indulgent casserole combines roasted sweet potatoes with rich butter and cream for pure comfort food bliss.
My friend Sandra absolutely raves about this buttery sweet potato casserole every holiday season. She brings it to every family gathering and it’s always the first dish to disappear.
What makes this side truly special is the balance of creamy texture and warm spices that feels both elegant and effortless. Unlike traditional recipes with marshmallow toppings, we’re focusing on a velvety filling with a crunchy pecan topping instead.
I created this recipe after Sandra requested a less-sweet version of her grandmother’s classic, and the result is restaurant-quality comfort on a plate. Whether you’re hosting Thanksgiving or a casual fall dinner, this crowd casserole deserves a permanent spot on your menu.

Ingredients for creamy buttery sweet potato casserole
- 3 lbs sweet potatoes
- 4 tbsp butter
- 1/2 cup heavy cream
- 1/4 cup brown sugar
- 1 tsp vanilla extract
- 1/2 tsp cinnamon
- 1/4 tsp nutmeg
- 1/4 tsp salt
- 1/8 tsp black pepper
- 1 cup pecans, chopped
- 2 tbsp maple syrup
- 1/2 cup marshmallows
For substitutions, you can swap heavy cream with half-and-half if you prefer a lighter texture, though the creamy filling won’t be quite as luxurious. Pecans can be replaced with walnuts or candied almonds depending on your preference, and maple syrup can be substituted with honey or agave nectar for a different flavor profile.
If you’re avoiding dairy, use coconut cream or cashew cream as a one-to-one replacement for the heavy cream and butter. These alternatives will give you a buttery sweet potato casserole with slightly different flavor notes but equally delicious results.
Step-by-step sweet potato casserole instructions
1. Preheat your oven to 375°F and line a large baking sheet with foil. Wash and prick the sweet potatoes several times with a fork to allow steam to escape during roasting.
2. Arrange the sweet potatoes on the prepared baking sheet and roast for 25-30 minutes until completely tender when pierced with a knife. Once cooled slightly, peel away the skin and cut into chunks for easier blending.
3. Add roasted sweet potato chunks to a food processor along with butter, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, salt, and black pepper. Pulse until the mixture reaches a smooth, creamy consistency without any lumps remaining.
4. Transfer the blended mixture to a buttered 9×13-inch baking dish, spreading evenly across the bottom. This creamy buttery sweet potato casserole base should be about 2 inches thick and ready for the topping.
5. In a small bowl, combine chopped pecans with maple syrup and a pinch of salt, stirring until the nuts are evenly coated. Sprinkle this mixture over the casserole filling, then dot the top with marshmallows for a classic touch.
6. Bake for 10-12 minutes until the marshmallows are light golden brown and the filling is heated through. Let cool for 5 minutes before serving to allow the buttery sweet potato side to set slightly.
