Introduction
Southern sweet potato casserole is a quintessential dish that graces many family tables, especially during holidays and gatherings. Its creamy texture, combined with a sweet, buttery topping, creates a comfort food that warms both heart and soul.
Made with simple ingredients, this casserole transforms humble sweet potatoes into a rich and delightful side dish. Whether it's served alongside roasted turkey or enjoyed at a potluck, each bite is a taste of Southern hospitality.
Ingredients
- 4 medium sweet potatoes
Sweet potatoes are the star of this dish, providing natural sweetness and a creamy texture when baked. They are rich in vitamins A and C, making this casserole a nutritious addition to any meal. - 1/2 cup brown sugar
Brown sugar adds depth of flavor and enhances the natural sweetness of the sweet potatoes. It also helps create that caramelized crust when baked, providing a contrast to the softness of the potatoes. - 1/4 cup unsalted butter, melted
The melted butter enriches the casserole, ensuring a smooth and creamy consistency. It also contributes to the overall flavor while helping the dish to brown beautifully in the oven. - 1/2 cup milk
Milk helps to thicken the mixture while adding a velvety mouthfeel. It balances out the sweetness and contributes to the overall moisture content of the casserole. - 2 large eggs
Eggs act as a binding agent in the casserole, helping to create a cohesive texture. They also add richness and protein, elevating the dish to a healthier option. - 1 teaspoon vanilla extract
Vanilla extract enhances the sweetness and flavor profile of the casserole, adding a lovely aroma that complements the other ingredients remarkably well. - 1 teaspoon ground cinnamon
Cinnamon adds warmth and a hint of spice, which pairs perfectly with the sweet potatoes. It creates that classic, nostalgic flavor often associated with Southern cooking. - 1/2 teaspoon nutmeg
Nutmeg introduces a slightly nutty and warm flavor that deepens the overall taste of the casserole. A little goes a long way to highlight the sweet potatoes' natural sweetness. - 1 cup mini marshmallows
Mini marshmallows are added as a topping, creating a delightful, gooey crust that melts into a sweet layer. They provide a playful textural contrast to the smooth casserole.
Directions & Preparation
Step 1: Preheat the oven to 350°F (175°C).
Preheating the oven is crucial to ensuring that your casserole bakes evenly. This temperature helps to create a golden-brown crust while thoroughly cooking the sweet potatoes in the mixture.
Step 2: Peel and chop the sweet potatoes into chunks.
Chopping the sweet potatoes into smaller chunks allows them to cook faster and more evenly. This ensures they become soft enough to mash and blend smoothly in the casserole.
Step 3: Boil the sweet potatoes in a large pot until fork-tender, about 15-20 minutes.
Boiling sweet potatoes softens them, making them easy to mash. Cooking until fork-tender ensures they are perfectly cooked without being too mushy, allowing for a great texture in the final dish.
Step 4: Drain the sweet potatoes and return them to the pot.
Returning the cooked sweet potatoes to the pot allows for easier mixing and mashing without the risk of spilling. It also preserves some heat, helping the potatoes to absorb other ingredients smoothly.
Step 5: Mash the sweet potatoes until smooth.
Mashing the sweet potatoes thoroughly helps create a creamy base for the casserole. This step is important to avoid any lumps, ensuring every bite is smooth and consistent in flavor.
Step 6: Stir in brown sugar, melted butter, milk, eggs, vanilla extract, cinnamon, and nutmeg until well combined.
Incorporating these ingredients evenly adds flavor, moisture, and richness to the casserole. This step is crucial for achieving the signature taste and texture characteristic of Southern sweet potato casseroles.
Step 7: Pour the mixture into a greased baking dish.
Choosing a greased baking dish prevents the casserole from sticking and makes for easier serving later on. Make sure to choose a size that allows for even cooking and browning.
Step 8: Bake in the preheated oven for 25-30 minutes until set.
Baking helps meld all the flavors together and creates a delightful crust on top. You'll know it’s ready when the edges are bubbling and the center is firm yet soft to the touch.
Step 9: Remove from oven, and sprinkle mini marshmallows over the top.
Adding mini marshmallows after the initial baking allows them to melt but not completely brown, preserving their texture. This topping is essential for that classic sweet contrast to the savory potatoes.
Step 10: Return to the oven for an additional 10 minutes, until marshmallows are golden.
This final baking step allows the marshmallows to become toasty and caramelized. Watching them closely is key to achieving that perfect golden brown without burning.
Step 11: Let the casserole cool for a few minutes before serving.
Allowing the casserole to cool briefly helps set the filling and makes it easier to cut and serve. This improves presentation and ensures guests can enjoy it without burning their mouths.

You can reduce the sugar by about a third without significantly affecting the taste, relying on the natural sweetness of the sweet potatoes. Just be cautious as it can impact the overall balance.
