Sweet Potato Casserole: A Classic Holiday Side Dish
I remember the smell of my grandmother’s kitchen every Thanksgiving — cinnamon, buttery sweet potatoes bubbling in a casserole dish, and the eager chatter of family gathered around the table. Sweet Potato Casserole has always felt like comfort wrapped in a little golden marshmallow crust. I love this dish because it’s equal parts nostalgia and simplicity: a humble root vegetable transformed into something celebratory. Sweet potatoes themselves have deep cultural roots in American holiday traditions, especially across the South, where they’re often used in festive dishes that blend Native American, African, and European influences. That warm history makes every bite taste like home.

Instructions

FAQ
Q: Can I freeze this recipe?
A: Yes. You can freeze the baked sweet potato mixture (without the marshmallow topping) in an airtight container for up to 3 months. Thaw in the refrigerator overnight, reheat in a baking dish, then add marshmallows and broil briefly to toast them just before serving.
Q: What can I use instead of mini marshmallows?
A: If you prefer not to use marshmallows, try a streusel topping made from brown sugar, flour, butter, and chopped pecans for a crunchy, caramelized finish.
Q: How can I make this ahead of time?
A: Assemble the casserole up to the step before adding marshmallows, cover, and refrigerate for up to 24 hours. Add marshmallows and bake when ready.
Q: How do I make this less sweet?
A: Reduce the sugar to 1/4 cup and skip the marshmallows or use a smaller amount. You can also add a splash more salt or a bit of lemon zest to balance sweetness.
Tips & Tricks
- Cook sweet potatoes until very tender so they mash smoothly — a fork should slide in easily.
- For a silkier texture, use a hand mixer briefly after mashing rather than overworking with a food processor (which can make them gluey).
- Toast pecans beforehand for extra flavor and crunch.
- If marshmallows brown too quickly, tent the dish with foil during the last few minutes and then broil briefly to finish the top if needed.
