The Key Ingredients for Authentic Flavor
The beauty of a traditional Southern Sweet Potato Casserole lies in its simple, high-quality ingredients. Here’s what you’ll need to create this masterpiece.
For the Sweet Potato Filling
- Sweet Potatoes: The star of the show. Use orange-fleshed varieties like Beauregard or Jewel for the best creamy texture and sweet flavor.
- Unsalted Butter: Adds richness and a velvety mouthfeel to the filling.
- Granulated Sugar & Brown Sugar: A mix of both provides the perfect sweetness and a hint of molasses flavor.
- Eggs: Act as a binder, giving the casserole structure and a custard-like consistency.
- Milk or Heavy Cream: Adds moisture and creaminess. For a richer casserole, opt for heavy cream.
- Vanilla Extract: Enhances all the warm, sweet flavors in the dish.
- Spices: A touch of cinnamon and nutmeg brings warmth and that classic holiday aroma.
For the Crunchy Pecan Topping
- Pecans: Chopped pecans are essential for that signature crunch.
- All-Purpose Flour: Helps bind the topping ingredients together.
- Brown Sugar: Creates a sweet, slightly caramelized crust as it bakes.
- Unsalted Butter: Cold, cubed butter is cut into the mixture to create a crumbly, streusel-like texture.
How to Make Southern Sweet Potato Casserole (Step-by-Step)
Follow these simple steps to create a show-stopping side dish. We’ve broken it down to ensure your casserole comes out perfectly.
Step 1: Cook the Sweet Potatoes
The first step is to cook the sweet potatoes until they are very tender. You can either boil or bake them. Baking them results in a more intense, concentrated sweet flavor, while boiling is slightly faster. For baking, pierce the potatoes with a fork, place them on a baking sheet, and bake at 400°F (200°C) for 45-60 minutes, or until easily pierced with a knife. Once cooked, let them cool slightly, then scoop the flesh out of the skins.
Step 2: Prepare the Filling
In a large bowl, mash the cooked sweet potato flesh until smooth. An electric mixer can make this job easier and result in a silkier texture. Add the melted butter, sugars, eggs, milk, vanilla, cinnamon, and nutmeg. Mix until everything is well combined and the filling is smooth and creamy.
Step 3: Make the Pecan Topping
In a separate bowl, combine the chopped pecans, flour, and brown sugar. Add the cold, cubed butter. Using a pastry blender or your fingers, cut the butter into the mixture until it resembles coarse crumbs. This method ensures a perfectly crisp and crumbly topping.
Step 4: Assemble and Bake
Spread the sweet potato filling evenly into a greased 9×13-inch baking dish. Sprinkle the pecan topping evenly over the filling. Bake in a preheated oven at 350°F (175°C) for 30-35 minutes, or until the filling is set and the topping is golden brown and crisp. Let it cool for a few minutes before serving.
Pro Tips for the Perfect Casserole
Want to take your casserole from great to unforgettable? Here are a few expert tips.
- Don’t Overmix the Filling: Mix just until the ingredients are combined. Overmixing can make the casserole dense.
- Use Cold Butter for the Topping: Just like making a pie crust, using cold butter for the streusel topping creates a flakier, crunchier texture.
- Toast the Pecans: For an even deeper, nuttier flavor, lightly toast the pecans in a dry skillet for a few minutes before adding them to the topping mixture.

Topping Variations: Pecans vs. Marshmallows
The great debate: pecans or marshmallows? While this recipe features a classic pecan streusel, you can easily swap it for a marshmallow topping. Simply prepare the sweet potato filling as directed and bake for about 20 minutes. Then, remove the casserole from the oven, top with a layer of mini marshmallows, and return it to the oven for another 10-15 minutes, or until the marshmallows are puffed and golden brown. Or, do half and half to please everyone!
Make-Ahead and Storage Instructions
This Southern Sweet Potato Casserole is a perfect make-ahead dish for the holidays, which helps free up oven space on the big day.
- To Make Ahead: Prepare the sweet potato filling and spread it in the baking dish. Prepare the pecan topping and store it in a separate airtight container. Cover and refrigerate both for up to 2 days. When ready to bake, sprinkle the topping over the filling and bake as directed, adding 5-10 minutes to the baking time.
- To Store: Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
- To Reheat: Reheat individual portions in the microwave or place the entire casserole in a 350°F (175°C) oven until warmed through.
