Ingredients

Scale

Sweet Potato Mixture

  • 3 Medium Sweet Potatoes
  • 1 Large Egg
  • 1/4 Cup Butter, melted
  • 1 Pinch Salt
  • 1/4 Cup Granulated Sugar
  • 1/3 Cup Brown Sugar
  • 1/2 teaspoon Cinnamon
  • 1/2 teaspoon Vanilla Extract
  • 2 Tablespoons Milk or Heavy Cream (any milk will do)

Topping

  • 2 Cups Mini Marshmallows
  • 1/3 Cup Butter, cold and cut in cubes
  • 1/2 Cup All-Purpose Flour
  • 3/4 Cup Brown Sugar
  • 1/2 teaspoon Cinnamon
  • 1/2 Cup Panko Bread Crumbs
  • 1/4 Cup Graham Cracker Crumbs

Instructions

  1. Prepare the Sweet Potatoes: Pierce the sweet potatoes with a fork and roast them in the oven at 400°F (204°C) for about 45-60 minutes until tender. Let them cool, then peel off the skins and mash the flesh until smooth.
  2. Mix the Filling: In a large bowl, combine the mashed sweet potatoes with the egg, melted butter, pinch of salt, granulated sugar, brown sugar, cinnamon, vanilla extract, and milk or cream. Mix thoroughly until the mixture is creamy and well incorporated.
  3. Prepare the Topping: In a separate bowl, mix the cold butter cubes with the flour, brown sugar, cinnamon, panko bread crumbs, and graham cracker crumbs. Using your fingers or a pastry cutter, blend until the mixture resembles coarse crumbs.
  4. Assemble the Casserole: Transfer the sweet potato mixture into a greased baking dish and spread it evenly. Sprinkle the crumb topping evenly over the sweet potato layer. Finally, sprinkle the mini marshmallows on top of the crumb mixture.
  5. Bake the Casserole: Bake the casserole in a preheated oven at 350°F (175°C) for 25-30 minutes, or until the topping is golden brown and the marshmallows are melted and slightly toasted.
  6. Serve: Allow the casserole to cool slightly before serving. Enjoy it warm as a delicious side dish during holiday meals or any cozy occasion.

Notes

  • You can cook sweet potatoes by boiling or microwaving if short on time, but roasting imparts the best flavor.
  • Substitute marshmallows with a nut topping for a less sweet version.
  • Use full-fat butter and cream for richer texture or opt for lighter dairy if desired.
  • The topping mixture can be made ahead and stored in the refrigerator.
