Recipe
Sweet potato casserole is a beloved holiday dish that combines the natural sweetness of sweet potatoes with a delightful crumbly topping. This comforting side dish is perfect for Thanksgiving dinners, Christmas feasts, or any special family gathering throughout the year.
This recipe creates a rich and creamy sweet potato base, topped with a crunchy pecan and brown sugar mixture that adds texture and additional sweetness. The contrast between the smooth, velvety sweet potatoes and the crispy topping makes for a truly satisfying culinary experience that will have your guests coming back for seconds.
- 4 large sweet potatoes, peeled and cubed
- 1/2 cup unsalted butter, melted
- 1/3 cup milk
- 1/2 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- For the topping:
- 1 cup packed brown sugar
- 1/3 cup all-purpose flour
- 1/3 cup unsalted butter, melted
- 1 cup chopped pecans
Preheat the oven to 375°F (190°C). Boil the sweet potatoes until tender, then drain and mash them. Mix in the melted butter, milk, sugar, eggs, vanilla, cinnamon, and salt. Pour the mixture into a greased 9×13 inch baking dish.
In a separate bowl, combine the brown sugar, flour, melted butter, and pecans for the topping. Sprinkle this mixture evenly over the sweet potato base. Bake for 25-30 minutes, or until the topping is golden brown and crispy.
For the best results, choose sweet potatoes that are firm and free from blemishes. You can prepare the sweet potato mixture a day in advance and refrigerate it, adding the topping just before baking.
If you prefer a marshmallow topping, replace the pecan mixture with mini marshmallows during the last 10 minutes of baking. For a healthier version, reduce the sugar in the sweet potato mixture and use a mixture of oats, nuts, and a small amount of brown sugar for the topping.
Cooking Steps
To create this delicious sweet potato casserole, you'll follow a series of simple steps.
You'll start by preheating your oven and preparing the sweet potato mixture, which forms the base of the dish.
Once that's ready, you'll add the pecan topping mixture, bake the casserole for 30 minutes, and then let it cool before serving.
Step 1. Preheat Oven to 350°F

Your oven's preheating is the first crucial step in preparing this delectable sweet potato casserole. Set your oven to 350°F (175°C) and allow it to fully heat up before you begin assembling your dish. This temperature is ideal for baking sweet potatoes, as it's hot enough to caramelize their natural sugars without burning them.
While your oven's warming up, you'll have time to prepare the other ingredients. Here's why preheating is so important:
- It ensures even cooking: A preheated oven maintains a consistent temperature throughout the baking process.
- It saves time: Your casserole will start cooking immediately when placed in a hot oven.
- It improves texture: The initial blast of heat helps create a crispy topping and tender interior.
Step 2. Prepare Sweet Potato Mixture

Now that your oven's warming up, let's focus on the star of the show: the sweet potato mixture. You'll need about 3 pounds of sweet potatoes, peeled and cut into chunks. Place them in a large pot, cover with water, and bring to a boil. Cook for 15-20 minutes until they're fork-tender, then drain well.
In a large mixing bowl, mash the cooked sweet potatoes until smooth. Add:
- 1/2 cup melted butter
- 1/2 cup milk
- 1/2 cup brown sugar
- 2 beaten eggs
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon salt
Mix these ingredients thoroughly with the mashed sweet potatoes. The result should be a creamy, well-blended mixture with a vibrant orange hue.
Don't worry if there are a few small lumps – they'll add character to your casserole.
Once you've achieved the desired consistency, transfer the mixture to a greased 9×13-inch baking dish. Spread it evenly, creating a smooth surface.
This preparation ensures that your sweet potato casserole will bake uniformly, resulting in a delicious, crowd-pleasing side dish.
Step 3. Add Pecan Topping Mixture

The pecan topping mixture adds a delicious crunch and sweetness to your sweet potato casserole. To prepare this irresistible layer, you'll need to combine a few key ingredients. In a medium bowl, mix together:
- 1 cup chopped pecans
- 1/2 cup brown sugar
- 1/3 cup all-purpose flour
- 1/4 cup melted butter
Stir these components until they're well combined and form a crumbly texture. The brown sugar will provide sweetness, while the flour helps bind everything together. The melted butter acts as the "glue" that'll create those perfect clusters of nutty goodness.
Once your sweet potato mixture is spread evenly in the baking dish, it's time to add this delectable topping. Sprinkle the pecan mixture over the sweet potatoes, making sure to distribute it evenly. Don't worry about pressing it down; it'll settle nicely during baking.
This topping isn't just about taste—it also adds a beautiful visual element to your casserole. As it bakes, the pecans will toast slightly, enhancing their flavor and creating an appealing golden-brown surface that's sure to impress your guests.
Step 4. Bake for 30 Minutes

With your casserole assembled and topped, it's time to bake it to perfection. Preheat your oven to 350°F (175°C) and place the casserole dish on the middle rack. Set your timer for 30 minutes and let the magic happen.
During this baking time, several important processes occur:
- The sweet potato mixture heats through, allowing flavors to meld.
- The marshmallows on top begin to melt and caramelize.
- The pecan topping becomes golden brown and crunchy.
Keep an eye on your casserole as it bakes. You'll know it's done when the edges are bubbling and the top is a beautiful golden brown. If you notice the pecan topping browning too quickly, you can loosely cover the dish with aluminum foil to prevent burning. After more than an hour in the oven, your casserole should be ready to serve. This green bean casserole recipe is perfect for family gatherings or holiday dinners, and the rich, savory flavor of the dish is sure to be a hit with your guests. Serve it alongside some creamy mashed potatoes and juicy roasted turkey for a perfect meal.
The aroma of sweet potatoes, cinnamon, and toasted pecans will fill your kitchen, building anticipation for the delicious treat to come.
Once the timer goes off, carefully remove the casserole from the oven using oven mitts. Let it cool for 5-10 minutes before serving, as this will allow the dish to set and make it easier to portion out.
Step 5. Let Cool Before Serving

Allowing your sweet potato casserole to cool is a crucial final step in the cooking process. After you've removed the dish from the oven, it's tempting to dive right in, but patience will reward you with a better texture and flavor.
Here's why cooling is important and how to do it properly:
- Temperature stabilization: As the casserole cools, the ingredients settle and firm up, making it easier to serve and enjoy.
- Flavor enhancement: Cooling allows the flavors to meld and intensify, resulting in a more delicious dish.
- Safety: Hot casseroles can cause burns, so cooling protects you and your guests.
To cool your casserole effectively:
- Place it on a heat-resistant surface.
- Let it sit at room temperature for 15-20 minutes.
- Use this time to prepare any additional toppings or side dishes.
- If you're not serving immediately, cover the cooled casserole with foil to keep it warm.
