this Recipe

Ingredients:

• 5 pounds sweet potatoes, about 4-5 large ones, for that robust, naturally sweet foundation that defines Moms Sweet Potato Casserole.
• 1/2 cup (1 stick) unsalted butter, melted, plus extra for greasing the baking dish. Good quality butter is key here; it adds richness and a wonderful flavor to our sweet potato base.
• 1/2 cup granulated sugar. You might adjust this slightly based on the sweetness of your potatoes and your personal preference, but this amount gives a lovely balance.
• 1/2 cup packed light brown sugar. This adds a deeper, more molasses-like sweetness that complements the sweet potatoes beautifully.
• 1/2 cup whole milk or half-and-half. For a truly creamy and luxurious texture, I often lean towards half-and-half, but whole milk works wonderfully too, contributing to the perfect consistency of this delightful Moms Sweet Potato Casserole.
• 2 large eggs, lightly beaten. These act as a binder, helping the casserole set and giving it a custardy texture.
• 2 teaspoons pure vanilla extract. Don’t skimp on this! It brightens all the flavors and adds an essential warmth.
• 1 teaspoon ground cinnamon. The quintessential spice for sweet potatoes, offering warmth and a comforting aroma.
• 1/2 teaspoon ground nutmeg. Just a touch adds an extra layer of spice complexity.
• 1/4 teaspoon ground ginger. For a subtle, peppery zing that elevates the overall flavor profile.
• Pinch of salt. Essential for balancing and enhancing all the sweet flavors.

For the Pecan Streusel Topping:

• 1 cup all-purpose flour. This forms the base of our crumbly, golden topping.
• 1/2 cup packed light brown sugar. For sweetness and that signature caramel-like flavor in the streusel.
• 1/2 cup chopped pecans, finely chopped. These add a delightful crunch and nutty flavor that pairs perfectly with the sweet potatoes.
• 1/2 cup (1 stick) cold unsalted butter, cut into small cubes. The cold butter is crucial for achieving that wonderfully crumbly texture.
• 1/2 teaspoon ground cinnamon. To tie the topping’s spice profile to the sweet potato base.
• Pinch of salt. Again, for balance and flavor enhancement.

Preparing the Sweet Potatoes for Our Moms Sweet Potato Casserole

1. Preheat and Prepare: First things first, let’s get our oven ready. Preheat your oven to 375°F (190°C). While the oven heats up, generously butter a 9×13-inch baking dish. You want to make sure it’s well-greased to prevent sticking and ensure a beautiful presentation for your finished Moms Sweet Potato Casserole.
2. Peel and Cube the Sweet Potatoes: Now for the star of our dish: the sweet potatoes! Carefully peel all 5 pounds of sweet potatoes using a sturdy vegetable peeler. Once peeled, cut them into roughly 1-inch uniform cubes. Aim for consistency in size, as this ensures they cook evenly. Uneven pieces can lead to some being mushy while others are still hard, and we want perfectly tender sweet potatoes for the creamiest casserole.
3. Boil to Perfection: Place the cubed sweet potatoes in a large pot. Fill the pot with cold water, making sure the water covers the sweet potatoes by at least an inch. Add a generous pinch of salt to the water – this helps season the potatoes from the inside out and enhances their natural sweetness. Bring the water to a rolling boil over high heat. Once boiling, reduce the heat to medium and let them simmer gently until they are fork-tender. This usually takes about 15-20 minutes, depending on the size of your cubes. You’ll know they’re ready when a fork slides into them with very little resistance.
4. Drain and Dry: Once tender, carefully drain the sweet potatoes thoroughly in a colander. This step is critical! Excess water can make your casserole watery, so let them sit for a few minutes to steam off any remaining moisture. You can even gently shake the colander a few times to help evaporate more water. This ensures a thick, rich base for your Moms Sweet Potato Casserole.

Crafting the Creamy Sweet Potato Base

5. Mash the Potatoes: Transfer the hot, drained sweet potatoes to a large mixing bowl. Now, it’s time to mash! You can use a potato masher for a slightly rustic texture, or for the absolute smoothest consistency that my mom always preferred, use an electric mixer on medium-low speed or a potato ricer. Mash until there are no lumps, or just a few small ones if you like a bit of texture. We’re aiming for a creamy, uniform base.
6. Incorporate the Fats and Sugars: To the mashed sweet potatoes, add the 1/2 cup of melted unsalted butter. The warmth of the potatoes will help integrate it beautifully. Next, stir in the 1/2 cup of granulated sugar and the 1/2 cup of packed light brown sugar. Mix well until the sugars are fully dissolved and evenly distributed throughout the sweet potato mixture. This foundational sweetness is what makes Moms Sweet Potato Casserole so incredibly satisfying.
7. Add the Wet Ingredients: Pour in the 1/2 cup of whole milk or half-and-half, followed by the 2 lightly beaten large eggs. The eggs will act as a binder, giving our casserole a lovely, almost custardy texture when baked. Mix these in thoroughly until everything is combined and the mixture looks smooth and luscious.
8. Spice it Up: Now for the warm, comforting spices! Add the 2 teaspoons of pure vanilla extract, 1 teaspoon of ground cinnamon, 1/2 teaspoon of ground nutmeg, 1/4 teaspoon of ground ginger, and the pinch of salt. Mix vigorously until all the spices are fully incorporated and you can smell their fragrant aroma wafting from the bowl. Give it a little taste test here – this is your chance to adjust the sweetness or spice levels to your liking. Does it need a little more cinnamon? A tiny bit more sugar? Make it perfect for your family’s taste buds! This meticulous seasoning is what sets Moms Sweet Potato Casserole apart.
9. Fill the Baking Dish: Spoon the entire sweet potato mixture into your prepared 9×13-inch baking dish. Use a spatula to spread it evenly and smooth out the top. Set this aside while we prepare our irresistible topping.

Preparing the Pecan Streusel Topping

10. Combine Dry Ingredients: In a medium mixing bowl, combine the 1 cup of all-purpose flour, 1/2 cup of packed light brown sugar, the 1/2 cup of finely chopped pecans, 1/2 teaspoon of ground cinnamon, and the pinch of salt. Use a fork or a whisk to mix these dry ingredients together thoroughly, ensuring there are no clumps of brown sugar.
11. Cut in the Butter: Add the 1/2 cup of cold unsalted butter, which you’ve cut into small cubes, to the dry ingredients. Now, using your fingertips, a pastry blender, or two knives, cut the butter into the flour mixture. Work quickly to prevent the butter from melting too much from the heat of your hands. You’re aiming for a coarse, crumbly mixture with some pea-sized pieces of butter still visible. These little butter pieces are what will melt and create that wonderful crispness in the oven, giving our Moms Sweet Potato Casserole a textural contrast.
12. Apply the Topping: Evenly sprinkle the pecan streusel topping over the smooth sweet potato mixture in the baking dish. Make sure it’s distributed from edge to edge so every serving gets a generous helping of that delightful crunch.

Baking Our Perfect Moms Sweet Potato Casserole

13. Bake to Golden Perfection: Place the baking dish in your preheated 375°F (190°C) oven. Bake for 30-35 minutes. You’ll know it’s ready when the sweet potato mixture is set and bubbling around the edges, and the pecan streusel topping is beautifully golden brown and smells absolutely divine. The exact baking time can vary slightly depending on your oven, so keep an eye on it after the 25-minute mark. The aroma filling your kitchen will be unmistakable – a true sign of a classic Moms Sweet Potato Casserole.
14. Optional Marshmallow Finish (My Mom’s Secret Twist!): If you want to add another layer of indulgence, and my mom often did, consider adding marshmallows! About 10 minutes before the end of the baking time (around the 20-25 minute mark), carefully remove the casserole from the oven. Evenly distribute 2-3 cups of miniature marshmallows over the pecan streusel topping. Return the casserole to the oven and continue baking for the remaining 5-10 minutes, or until the marshmallows are puffed, lightly golden brown, and delightfully gooey. Watch them carefully, as they can burn quickly! This addition transforms an already amazing dish into an unforgettable Moms Sweet Potato Casserole experience.
15. Cool and Serve: Once baked to perfection, carefully remove the Moms Sweet Potato Casserole from the oven. Let it cool on a wire rack for at least 10-15 minutes before serving. This cooling period allows the casserole to set further, making it easier to scoop and ensuring the flavors have a moment to meld together beautifully. Serving it slightly warm is truly the best way to enjoy its comforting flavors and textures.
16. Enjoy! This casserole is fantastic served warm as a side dish for any holiday meal or family gathering. The rich, creamy sweet potato base, combined with the crunchy, sweet pecan streusel and optional gooey marshmallows, makes for an incredibly satisfying and memorable dish. It’s truly a labor of love that brings warmth and happiness to any table, embodying the very essence of a homemade Moms Sweet Potato Casserole. Leftovers, if there are any, can be stored in an airtight container in the refrigerator for up to 3-4 days and reheated gently in the oven or microwave.

Of course, it’s an absolute non-negotiable for Thanksgiving and Christmas dinners, serving as the perfect counterpoint to roasted turkey, glazed ham, or a succulent prime rib. But don’t relegate it solely to the holidays! It’s equally wonderful as an accompaniment to a simple roasted chicken, pork chops, or even alongside a hearty vegetarian lentil loaf for a comforting weeknight meal. For a surprising twist, try serving leftovers for brunch alongside scrambled eggs and crispy bacon – the sweet and savory combination is unexpectedly delightful.

And for those who love to experiment, the possibilities for variations are plentiful! If you’re not a fan of nuts or have allergies, feel free to omit the pecan topping entirely, or swap it for a buttery streusel made with oats and brown sugar for a different kind of crunch. For a less sweet profile, slightly reduce the amount of sugar in the sweet potato mixture, allowing the natural sweetness of the potatoes to shine even more. If you crave an extra layer of warmth, a pinch of ground ginger or even a tiny dash of cayenne pepper can add a subtle kick that will intrigue your taste buds. For a dairy-free version, simply substitute plant-based milk and butter, ensuring the same creamy consistency and rich flavor. You can also bake this casserole in individual ramekins for elegant single servings, perfect for a dinner party. And for the ultimate indulgence, a handful of mini marshmallows melted to a golden brown on top is always a crowd-pleaser, adding another layer of sweetness and a gooey texture.
