  • ½ teaspoon ground nutmeg
  • ¼ teaspoon ground ginger
  • ¼ teaspoon salt
  • Mini marshmallows for topping

Directions

Roast the Sweet Potatoes

  1. Preheat the oven to 425°F (220°C).
  2. Place sweet potatoes on a foil-lined baking sheet and poke each several times with a fork.
  3. Roast for 50-60 minutes until tender. Let cool slightly, then peel and purée the flesh in a food processor or blender until smooth.

Reduce Oven Temperature

  1. Lower the oven to 350°F (175°C).

Prepare the Filling

  2. Add granulated sugar and brown sugar, then mix well.
  3. Beat in the eggs until fully incorporated.
  4. Stir in evaporated milk, vanilla, cinnamon, nutmeg, ginger, and salt until smooth and creamy.

Assemble the Pie

  1. Place the pie crust on a baking sheet.
  2. Pour the sweet potato filling into the crust and smooth the top.

Bake the Pie

  1. Bake at 350°F for 50-60 minutes, until the filling is set and the crust is golden.
  2. The center may jiggle slightly but will firm up as it cools.

Cool the Pie

  1. Allow the pie to cool for at least 30 minutes.

Add Marshmallow Topping

  1. Preheat the broiler on high.
  2. Spread mini marshmallows in a single layer over the pie. Optionally, sprinkle chopped pecans on top for added texture.
  3. Toast under the broiler for 1-2 minutes until the marshmallows are golden brown. Watch closely to avoid burning.

Serve

  1. Let the pie cool to room temperature (1-2 hours) and refrigerate for 1-2 more hours for a firmer texture.
  2. Slice and serve warm or chilled. Enjoy!

Sweet Potato Pie with Marshmallows

FAQs

1. Can I use canned sweet potatoes instead of fresh ones?

Yes, but fresh sweet potatoes provide a better texture and flavor. If using canned, drain and mash them well.

2. How do I prevent my pie from cracking?

Avoid overbaking. The center should be slightly jiggly when removed from the oven, as it will firm up while cooling.

3. Can I make this pie without marshmallows?

Absolutely! You can top it with whipped cream, a pecan streusel, or leave it plain.

4. How do I know when the pie is fully baked?

Insert a knife or toothpick into the center; if it comes out mostly clean, the pie is ready.

5. Can I use a graham cracker crust instead of a traditional pie crust?

Yes! A graham cracker crust adds a delicious twist to the classic pie.

6. How far in advance can I make this pie?

You can make it 1-2 days in advance and store it in the fridge. Add the marshmallow topping just before serving.

7. Can I use a store-bought sweet potato purée?

Yes, but ensure it’s unsweetened and unseasoned for the best results.

8. What can I substitute for evaporated milk?

Heavy cream, half-and-half, or whole milk work well as substitutes.

9. How do I keep the marshmallows from burning?

Broil them for only 1-2 minutes and keep a close eye on them. You can also use a kitchen torch for more control.

10. Can I make this pie gluten-free?

Yes! Simply use a gluten-free pie crust or make a crustless version.

Conclusion

Sweet Potato Pie with Marshmallows is a classic holiday dessert that’s rich, creamy, and perfectly spiced. The toasted marshmallow topping adds a delightful sweetness and festive touch, making it a must-have treat for Thanksgiving or Christmas. Whether served warm or chilled, this pie is sure to be a crowd-pleaser at any gathering. Enjoy baking and sharing this comforting dessert with your loved ones!
