## The Classic Sweet Potato Casserole with Marshmallows
Let’s start with the classic version – the one most people associate with sweet potato casserole. This recipe relies on marshmallows for its signature sweetness and gooey texture.
**Ingredients:**
* 4 pounds sweet potatoes, peeled and cubed
* 1/2 cup unsalted butter, melted
* 1/2 cup granulated sugar
* 1/4 cup milk
* 1 teaspoon vanilla extract
* 1/2 teaspoon ground cinnamon
* 1/4 teaspoon ground nutmeg
* Pinch of salt
* 2 cups mini marshmallows
**Instructions:**
1. **Prepare the Sweet Potatoes:** Preheat oven to 350°F (175°C). Place the cubed sweet potatoes in a large pot and cover with water. Bring to a boil and cook until tender, about 15-20 minutes. Drain well.
2. **Mash the Sweet Potatoes:** Return the cooked sweet potatoes to the pot. Add the melted butter, sugar, milk, vanilla extract, cinnamon, nutmeg, and salt. Use a potato masher or electric mixer to mash until smooth.
3. **Assemble the Casserole:** Transfer the mashed sweet potatoes to a greased 9×13 inch baking dish. Spread evenly.
4. **Add the Marshmallows:** Sprinkle the mini marshmallows evenly over the top of the sweet potato mixture.
5. **Bake:** Bake for 20-25 minutes, or until the marshmallows are golden brown and slightly puffed. Watch carefully to prevent burning.
6. **Cool and Serve:** Let the casserole cool slightly before serving. The marshmallows will be very hot!
**Tips for Perfect Marshmallow Casserole:**
* **Don’t Overcook the Marshmallows:** Keep a close eye on the casserole while it’s baking. Marshmallows burn easily, so remove it from the oven as soon as they are golden brown.
* **Use Fresh Marshmallows:** Stale marshmallows tend to melt unevenly and may not get as gooey.
* **Add a Layer of Pecans (Optional):** For added flavor and texture, sprinkle a layer of chopped pecans over the sweet potato mixture before adding the marshmallows.
* **Broil for Extra Color:** If the marshmallows aren’t browning to your liking, broil the casserole for a minute or two at the end, but watch it *very* carefully to prevent burning.
