Ingredients
For the Sweet Potato Casserole
2–3 lbs sweet potatoes
6 tbsp butter, melted
½ cup brown sugar
1 tbsp ground cinnamon
1 tsp ground nutmeg
1 tsp vanilla extract
1 tsp salt
For the Famous Topping
10 oz marshmallows
Additional brown sugar, optional
Step By Step
1️⃣ Bake the Sweet Potatoes
Preheat your oven to 400°F. Wash and dry the sweet potatoes, then pierce each several times with a fork to release steam. Lightly rub with oil if desired, wrap loosely in aluminum foil, and arrange on a baking sheet. Bake for 45–60 minutes, or longer for larger potatoes, until completely tender.
2️⃣ Make Them Creamy
Allow the potatoes to cool slightly, then remove the skins. Transfer the flesh to a large mixing bowl and mash until smooth and creamy.
3️⃣ Bring on the Holiday Spices
Add the melted butter, brown sugar, cinnamon, nutmeg, vanilla extract, and salt. Mix thoroughly until everything is beautifully combined. The mixture should be silky, buttery, and fragrant with warm holiday spices.
4️⃣ Build Your Casserole
Reduce the oven temperature to 375°F. Lightly grease a baking dish and spoon in the sweet potato mixture. Spread into an even layer and, if you love a little extra sweetness, sprinkle with additional brown sugar.
5️⃣ Bake Until Bubbling
Place the casserole in the oven and bake for 30 minutes. The filling should be heated through and beginning to develop a lightly caramelized surface.
6️⃣ The Moment of Controversy!
Remove the casserole from the oven. Scatter the marshmallows generously over the top, covering the sweet potatoes in a fluffy white blanket. Return to the oven for approximately 10 minutes, watching carefully until the marshmallows become beautifully golden and toasted.
7️⃣ Serve & Let the Debate Begin
Remove from the oven and allow to rest briefly before serving. Bring the casserole to the table while the topping is still warm, gooey, and gloriously golden. Let the marshmallow lovers celebrate. Let the skeptics raise their eyebrows. And let everyone enjoy Thanksgiving.
