This creamy sweet potato casserole is a nostalgic holiday dish that fills the kitchen with the scent of toasted marshmallows and warm vanilla. It is a perfect sweet side for gatherings and always disappears quickly at our table. The soft mashed sweet potatoes, buttery richness, and caramelized marshmallow topping come together for a comfort food classic.

The first time I baked this for Thanksgiving, everyone went back for seconds and asked for the recipe. It is one of those simple dishes that instantly reminds me of family celebrations and cozy evenings.

Ingredients

  • Large sweet potatoes: Choose ones that feel heavy for their size and have no blemishes or sprouts. They create the creamy base for the casserole.
  • Brown sugar: This adds that classic caramel flavor. Look for soft, moist brown sugar for easy blending.
  • Unsalted butter: Brings a rich texture and depth of taste. Choose high quality butter for best results.
  • Milk: Makes the mash silky and smooth. Whole milk gives the richest results but any milk variety will work.
  • Vanilla extract: Gives a warm aroma. Look for pure vanilla extract for the best flavor.
  • Mini marshmallows: Melts and caramelizes on top for a fun sweet bite. Pick fresh marshmallows that feel light and pillowy.

Instructions

Boil and Prep the Sweet Potatoes:
Peel and cube sweet potatoes into even pieces so they cook at the same rate. Place them in a large pot and fill with enough water to cover. Simmer until they are fork tender, which usually takes about 15 to 18 minutes.
Drain and Mash:
Once potatoes are soft, pour them into a colander to drain off all water. Return to a large mixing bowl and start mashing. Using a potato masher or hand mixer makes the mash extra creamy.
Add the Mix-Ins:
Blend in brown sugar, soft butter, milk, and vanilla extract. Mix everything together until completely smooth and the butter is melted. Taste and adjust sweetness if needed.
Transfer and Top:
Spread the sweet potato mixture evenly into a greased baking dish. Scatter mini marshmallows all over the top for that signature sweet toasted finish.
Bake to Perfection:
Bake in a preheated oven at three hundred fifty degrees Fahrenheit or one hundred seventy five degrees Celsius for twenty five to thirty minutes. The marshmallows should be golden and the casserole should be heated through. Serve warm.

My favorite thing about this recipe is that marshmallow topping. It reminds me of when I was a kid and used to pick the gooey bits off the top before anyone else got to the dish. Now my own kids do the same and it always makes us laugh at the table.

Storage Tips

This casserole stores well refrigerated for up to four days. Just cover the pan tightly with foil. To reheat, bake at three hundred degrees Fahrenheit covered until hot then uncover to re crisp the marshmallows. If freezing, wrap portions tightly without marshmallows and add fresh topping before heating.

Ingredient Substitutions

You can swap out brown sugar for pure maple syrup for a different sweetness. Dairy free butter and almond or oat milk both work if you need a lactose free version. Nut topping like pecans can be added before baking for crunch instead of marshmallows.

Serving Suggestions

This casserole shines as a side with roast turkey, chicken, or ham. It also goes well with savory dishes like green beans or stuffing. For a fall brunch, try serving with scrambled eggs and sausage.

Cultural and Historical Context

Sweet potato casserole has Southern roots and is a beloved part of American holiday feasts. Marshmallow topping became popular in the twentieth century as manufacturers promoted creative uses for marshmallows through home cooking. Today it is a fixture at Thanksgiving tables across the country.

Seasonal Adaptations

Highlight local sweet potatoes in the autumn for extra flavor. You can add a pinch of cinnamon or nutmeg for warm spices during the fall and winter seasons. For summer barbecues swap marshmallows for a crumbly pecan topping.

Success Stories

I have served this dish at family reunions and it always gets rave reviews. Once my niece helped me stir the butter and marshmallows and proudly insisted on making it her job every year. It is the sort of tradition that makes the holidays sweeter.

Freezer Meal Conversion

To freeze, mix and assemble the sweet potato base in a dish and cool completely. Skip the marshmallows for now. Wrap well and freeze up to two months. Thaw overnight in the refrigerator then add marshmallows and bake as usual.
