Ingredients:

For the Sweet Potato Casserole Base:
- 6-7 medium-sized sweet potatoes (about 3-3.5 pounds total), peeled and cut into 1-inch chunks
- ½ cup (1 stick) unsalted butter, melted, plus extra for greasing the baking dish
- ½ cup granulated sugar
- ¼ cup packed light brown sugar
- ½ cup milk (whole milk or 2% works wonderfully)
- 2 large eggs, at room temperature, lightly beaten
- 2 teaspoons pure vanilla extract
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
- ¼ teaspoon ground ginger (optional, but adds depth!)
- Pinch of salt
For the Pecan Streusel Topping:
- ½ cup (1 stick) unsalted butter, melted
- 1 cup all-purpose flour
- 1 cup packed light brown sugar
- 1 cup chopped pecans
- ¼ teaspoon salt

Preparing the Sweet Potato Base

Preheat your oven and prepare the sweet potatoes: Let’s get started on creating that incredible base for our Copycat Sweet Potato Casserole! First things first, preheat your oven to a cozy 375°F (190°C). While the oven is warming up, grab your beautiful sweet potatoes. I always recommend choosing ones that feel firm and have smooth skin. Peel them diligently and then cut them into roughly 1-inch chunks. Uniformity here is key, as it ensures they all cook at the same rate. This is a crucial step for achieving that perfectly creamy texture in our casserole.
Boil the sweet potatoes until fork-tender: Now, transfer those chopped sweet potatoes into a large pot. Fill the pot with cold water, just enough to cover the potatoes by about an inch. Add a pinch of salt to the water – this helps to season the potatoes from the inside out and enhances their natural sweetness. Bring the water to a rolling boil over medium-high heat. Once boiling, reduce the heat slightly and let them simmer away until they are wonderfully fork-tender. This usually takes about 15-20 minutes, depending on the size of your chunks. You’ll know they’re ready when a fork easily slides into the center of a potato piece. Don’t overcook them to the point of mush, but ensure they are soft enough to mash easily.
Drain and mash the sweet potatoes: Carefully drain the cooked sweet potatoes thoroughly using a colander. I often let them sit in the colander for a minute or two to allow any excess steam to escape, which helps prevent a watery casserole. Transfer the drained sweet potatoes into a large mixing bowl. Now comes the fun part: mashing! You can use a potato masher for a slightly rustic texture, or for that super smooth, velvety Copycat Sweet Potato Casserole texture we’re aiming for, an electric hand mixer or even a stand mixer works wonders. Mash them until they are as smooth as you like, making sure there are no large lumps remaining.
Combine with the wet ingredients and spices: While the mashed sweet potatoes are still warm, which helps everything incorporate beautifully, it’s time to add in all those delicious flavor enhancers. Pour in the ½ cup of melted unsalted butter. Follow that with the granulated sugar and the light brown sugar. The combination of these two sugars provides a balanced sweetness and a lovely caramel note that truly elevates the dish. Stir in the milk, which helps achieve that creamy consistency, and then add your lightly beaten eggs. Eggs act as a binder, giving the casserole structure.
Infuse with fragrant spices and vanilla: Now for the aromatic heart of our Copycat Sweet Potato Casserole. Add the pure vanilla extract – I always recommend a good quality extract here, as it makes a noticeable difference. Sprinkle in the ground cinnamon, ground nutmeg, and if you’re feeling adventurous like me, a touch of ground ginger. These spices are what give this casserole its signature warmth and holiday feel. Finally, add that pinch of salt we discussed earlier. Mix everything together really well, either by hand with a sturdy spatula or with your electric mixer on low speed, until the mixture is completely smooth and all the ingredients are fully incorporated. Taste it! This is your chance to adjust the sweetness or spices to your personal preference.
Prepare your baking dish: Lightly grease a 9×13-inch baking dish with a little extra butter or non-stick cooking spray. This will prevent your delicious Copycat Sweet Potato Casserole from sticking and ensure easy serving. Pour the prepared sweet potato mixture evenly into the greased baking dish, spreading it out with a spatula to create a smooth, level surface. Set this aside while we prepare the irresistible pecan streusel topping.

Crafting the Pecan Streusel Topping

Melt the butter for the topping: In a medium-sized mixing bowl, melt the ½ cup of unsalted butter. You can do this gently on the stovetop or in the microwave. Just make sure it’s fully melted but not browned, as we want to mix it into our dry ingredients.
Combine dry ingredients for the streusel: To the bowl with the melted butter, add the all-purpose flour, the packed light brown sugar, and the ¼ teaspoon of salt. The brown sugar provides a wonderfully moist and caramel-like sweetness to the topping, which perfectly complements the sweet potato base. The salt, once again, balances the sweetness and brings out all the flavors.
Add the chopped pecans: Finally, fold in the chopped pecans. I prefer to chop them myself, but pre-chopped works too. Make sure they are roughly chopped, as you want a nice texture in every bite. Pecans are truly the star of this streusel and give our Copycat Sweet Potato Casserole that classic, crunchy topping.
Mix until crumbly: Using a fork or your fingertips, mix all the streusel ingredients together until they form a coarse, crumbly mixture. It shouldn’t be a uniform paste, but rather a collection of delightful buttery crumbs. This is the texture you want for that perfect crispy topping when baked. If it seems too wet, add a tiny bit more flour; if too dry, a tiny bit more melted butter. The goal is a loose, crumbly texture.

Assembling and Baking Your Copycat Sweet Potato Casserole

Spread the streusel topping: Take your baking dish with the sweet potato mixture and generously sprinkle the pecan streusel topping evenly over the entire surface. Make sure to get good coverage, as every bite deserves some of that crunchy, buttery goodness. Don’t press it down too much; we want it to remain light and airy to achieve maximum crispness.
Bake to perfection: Carefully place the baking dish into your preheated 375°F (190°C) oven. Allow your Copycat Sweet Potato Casserole to bake for approximately 30-40 minutes. You’re looking for a few key indicators of doneness: the sweet potato base should be set and slightly puffed, and the streusel topping should be beautifully golden brown and delightfully bubbly around the edges. The aroma filling your kitchen will be absolutely incredible – a sure sign of deliciousness to come! If you notice the topping browning too quickly, you can loosely tent the casserole with aluminum foil for the last 10-15 minutes of baking.
Cool slightly before serving: Once baked to perfection, carefully remove the Copycat Sweet Potato Casserole from the oven. Resist the urge to dive in immediately! It’s best to let it cool for about 10-15 minutes on a wire rack before serving. This brief cooling period allows the casserole to set further, making it easier to scoop and ensuring that the flavors meld together even more beautifully. Plus, it’ll be less scorching hot on your tongue!

Serving Suggestions and Storage

Serve warm: This Copycat Sweet Potato Casserole is truly best served warm, allowing its creamy texture and rich flavors to shine. It makes an absolutely fantastic side dish for any holiday meal – Thanksgiving, Christmas, Easter, or even just a cozy Sunday dinner. It pairs wonderfully with roasted turkey, ham, or chicken. Some people even enjoy it as a decadent dessert due to its sweetness, making it incredibly versatile.
Garnish (optional): For an extra touch of elegance, you can sprinkle a few whole toasted pecans on top right before serving, or a very light dusting of powdered sugar if you’re serving it as a dessert. A tiny dollop of freshly whipped cream can also be a delightful addition if you’re leaning towards the dessert angle.
Storage instructions: If you’re lucky enough to have leftovers (which is rare in my house!), they can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can gently warm individual portions in the microwave, or cover the entire dish with foil and reheat in a preheated 300°F (150°C) oven until warmed through, about 20-30 minutes. Be mindful that the streusel topping might lose some of its crispness upon reheating, but the flavor will still be absolutely delicious.
Freezing instructions (make-ahead option): This Copycat Sweet Potato Casserole is also a fantastic dish to prepare ahead of time! You can assemble the entire casserole, including the streusel topping, cover it tightly with plastic wrap and then aluminum foil, and freeze it unbaked for up to 2-3 months. When you’re ready to bake, thaw it in the refrigerator overnight, then bake as directed. Alternatively, you can bake it from frozen – simply add an extra 30-45 minutes to the baking time, covering it with foil for the first part of baking to prevent the topping from over-browning, then uncover for the last 15-20 minutes. If you wish to freeze it after baking, cool it completely, then cover tightly and freeze. Reheat thawed, covered, in a 350°F (175°C) oven until heated through.
Enjoy your homemade delight: And there you have it! A truly magnificent Copycat Sweet Potato Casserole that rivals any restaurant version. It’s a labor of love, but every creamy, sweet, and crunchy bite is absolutely worth it. This recipe is designed to bring warmth and joy to your table, and I truly hope you and your loved ones enjoy making and savoring this incredible dish. Happy cooking!

Elevate Your Table: Serving Suggestions and Creative Variations

Now that you’re armed with the knowledge to create this masterpiece, let’s talk about how to truly make it sing. While the Copycat Sweet Potato Casserole is an undisputed star on any Thanksgiving or Christmas spread – pairing harmoniously with roasted turkey, glazed ham, or a succulent prime rib – its versatility extends far beyond the holiday season. Imagine serving a generous scoop alongside a perfectly seared pork chop for an elevated weeknight dinner, or bringing a smile to brunch guests’ faces when offered next to fluffy scrambled eggs and crispy bacon. It can even double as a surprisingly satisfying dessert when served warm with a dollop of vanilla bean ice cream or a sprinkle of toasted pecans. But don’t stop there! This recipe is a fantastic canvas for your own creative flair.

Topping Transformations:

If you’re feeling adventurous, consider variations for the topping. While our classic streusel is divine, a traditional marshmallow topping, gently toasted until golden and gooey, offers a nostalgic, fluffy cloud of sweetness. For a more sophisticated touch, try incorporating toasted coconut flakes into your pecan streusel, adding an exotic aroma and another layer of crunch. Or, for a hint of warmth and spice, a generous dusting of freshly grated nutmeg or a pinch of allspice can be folded into the streusel mixture. You could even experiment with different nuts – walnuts or hazelnuts could offer a delightful twist, or for a nut-free option, crushed cornflakes mixed with brown sugar and butter create a wonderful crisp texture.

Flavor Fusions within the Casserole:

Within the creamy sweet potato base itself, there are opportunities for personalization. A small splash of bourbon or rum can introduce a sophisticated depth of flavor, perfect for adult palates. For a brighter profile, a hint of orange zest can elevate the natural sweetness of the potatoes, cutting through the richness beautifully. If you prefer a less sweet profile, feel free to slightly reduce the amount of sugar, allowing the natural earthiness of the sweet potatoes to shine through. For those with dietary considerations, plant-based milks like almond or oat milk can often be substituted successfully, along with vegan butter, without significantly compromising the indulgent texture. Don’t be afraid to adjust the spices; a touch of ginger or a tiny pinch of cayenne pepper can add an unexpected, subtle warmth that tantalizes the taste buds.
