The holiday season is upon us, and nothing brings people together quite like the warm, sweet aroma of a freshly baked sweet potato casserole with marshmallows. Picture this: it’s a cozy evening, the kitchen is filled with laughter, and you’re surrounded by family. As you lift the lid off the casserole dish, a wave of buttery sweetness envelops you, and the golden marshmallows glisten like little treasures. You can hardly wait to dig in! This beloved dish is more than just a side; it’s a slice of nostalgia, a holiday tradition that has been passed down through generations. Let’s make this Thanksgiving unforgettable with a sweet potato casserole that will elevate your feast and delight your loved ones.

My journey with sweet potato casserole began in my grandmother’s kitchen. She would whip up a batch every year, and I was always assigned the crucial task of mashing the sweet potatoes. The blend of creamy texture and sugary goodness has forever held a special place in my heart. Recently, I’ve noticed a rise in baking with seasonal root vegetables, aligning perfectly with the farm-to-table trend that celebrates locally sourced ingredients. As I crafted this recipe, I aimed to capture that classic flavor while making it accessible for everyone, ensuring all can enjoy this comforting dish at their holiday table.
Sweet Potatoes
- 4 large sweet potatoes – Velvety texture and natural sweetness.
- 1 cup brown sugar – Adds depth and caramel notes.
- 1/2 cup to 1 cup milk – Makes it creamy; can be dairy-free with almond or coconut milk.
- 1/2 cup butter – Rich, creamy flavor; replace with vegan butter if needed.
- 1 teaspoon vanilla extract – Enhances sweetness.
- 1/2 cup chopped pecans – Adds a crunchy texture; can substitute with walnuts or almonds.
- 2 cups mini marshmallows – Sweet, gooey topping that melts beautifully.
Step-by-Step Instructions
Begin by preheating your oven to 350°F (175°C). While the oven warms up, peel the sweet potatoes and chop them into equally sized chunks to ensure even cooking. Boil them in a large pot of salted water until they’re tender, for about 15-20 minutes. Drain and let them cool slightly before transferring them to a mixing bowl.
Next, mash the sweet potatoes with a potato masher or fork, adding in brown sugar, butter, milk, and vanilla extract. Mix until creamy and smooth. Don’t be shy to taste and adjust the sweetness to your liking! Then, fold in half a cup of chopped pecans for an added crunch. The texture of the sweet potatoes should be fluffy and light, embodying that perfect comforting quality.
Transfer the sweet potato mixture to a greased 9×13-inch baking dish, spreading evenly. Now it’s time for the pièce de résistance! Top the mixture generously with mini marshmallows and sprinkle the remaining pecans on top. Bake for 25-30 minutes until the marshmallows are beautifully toasted and golden brown, creating that irresistible crispy layer that contrasts perfectly with the smooth sweet potato base.
Expert Tips
One of my tested techniques to elevate this dish involves broiling the marshmallows for a minute or two at the end of baking—just keep a close eye to prevent burning! For those short on time, consider using pre-cooked sweet potatoes or even canned varieties for a quick shortcut. Always mix in some spices like cinnamon or nutmeg for warmth; these flavors complement the sweetness beautifully. If you ever find your casserole a bit too thick, add a splash more milk to get that perfect creamy consistency.
Storage & Substitutions
This sweet potato casserole can be made ahead of time—simply prepare it entirely, cover it tightly with foil, and store it in the refrigerator for up to 3 days. When ready to serve, just pop it in the oven to heat through. Leftovers can be stored in an airtight container in the fridge for up to a week or frozen for up to three months. Just remember to adjust the marshmallow topping; it’s best added before the final baking to keep that soft texture fluffy.
How do I make this recipe ahead?
You can prepare the sweet potato mixture a day in advance and store it in the refrigerator. Just before baking, top with marshmallows and pecans.
Can I use regular potatoes instead of sweet potatoes?
While you can use regular potatoes, the flavor and texture will differ significantly. Sweet potatoes provide that distinct sweetness and creaminess that defines this dish.
What if I don’t have pecans?
Pecans can be easily substituted with walnuts, almonds, or even sunflower seeds for a nut-free option. The goal is to add a nice crunch to balance the soft casserole.
Is it necessary to peel the sweet potatoes?
Peeling is traditional, but if you prefer rustic appeal or extra fiber, feel free to leave the skins on. Just make sure to scrub them thoroughly!
Can I use marshmallow fluff instead of mini marshmallows?
Yes! Marshmallow fluff can give a similar sweet topping. Spread it evenly on your casserole before baking for a beautifully soft finish.
How can I make this recipe a little healthier?
For a healthier twist, you can reduce the sugar, use a sugar substitute, or add mashed banana for extra sweetness. Unsweetened almond milk is a great dairy-free alternative.
