Ingredients
- 3 pounds sweet potatoes (about 4 large), peeled and cut into chunks
- 4 tablespoons unsalted butter, softened
- ½ cup packed brown sugar
- ½ cup whole milk or 2% milk (almond milk for dairy-free version)
- 1 teaspoon vanilla extract
- 2 tablespoons fresh orange juice (optional)
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ½ teaspoon salt
- 2 cups mini marshmallows
Instructions
- Place peeled and chopped sweet potatoes into a large pot and cover with cold water. Bring to a boil over medium-high heat, then simmer for 15-20 minutes until tender when pierced with a fork. Drain well in a colander.
- Return drained potatoes to the pot or a large mixing bowl. Mash using an electric mixer or potato masher until mostly smooth with a few lumps remaining.
- Stir in softened butter, brown sugar, milk, vanilla extract, and orange juice. Add cinnamon, nutmeg, and salt. Mix thoroughly until creamy and fragrant. Taste and adjust sugar or spices if desired.
- Spoon the sweet potato mixture into a greased 9×13-inch casserole dish, spreading evenly.
- Scatter mini marshmallows evenly over the surface, covering all edges for a golden crust.
- Preheat oven to 350°F (175°C). Bake casserole on the middle rack for 25-30 minutes, or until marshmallows are puffed and golden brown. Watch closely after 20 minutes to avoid burning.
- Let casserole rest for 5-10 minutes before serving to firm up and keep marshmallow topping intact.
- Optional: For extra color and crunch, toast marshmallows under the broiler for 1-2 minutes at the end, watching carefully to prevent burning.
Notes
For deeper flavor, roast sweet potatoes at 400°F for 45 minutes instead of boiling. Avoid overmixing to prevent gluey texture. Add marshmallows in the last 10 minutes for gooey topping or at the start for crunchier crust. Use vegan substitutes for dairy and marshmallows to make vegan version. Store leftovers covered in fridge up to 3 days; reheat gently in oven to preserve topping texture. Freezing is possible but not ideal for marshmallow topping.
