Ingredients

  • 3 pounds sweet potatoes peeled and cut into 1-inch cubes
  • cup brown sugar
  • 2 large eggs beaten
  • ½ cup milk
  • 6 tablespoon unsalted butter melted
  • 1 teaspoon vanilla extract
  • ½ teaspoon ground cinnamon
  • 1 teaspoon salt

For the Pecan and Marshmallow Topping

  • 1 cup toasted pecans roughly chopped
  • 2 tablespoon all-purpose flour
  • 3 tablespoon brown sugar
  • 4 tablespoon butter melted
  • 2 cups mini marshmallows

Instructions

  • Preheat the oven to 350 degrees F and arrange the oven rack in the center position.
  • Grease a large 9x13-inch casserole dish or baking dish. Set aside.
  • Thoroughly wash, peel, and chop the sweet potatoes into 1-inch cubes. Transfer to a large pot or Dutch oven and cover with cold water. Bring to a boil, cover, and reduce heat to a simmer. Allow potatoes to cook for approximately 15 minutes, or until tender when pierced with a fork.
  • As the potatoes cook, mix together the brown sugar, eggs, milk, butter, vanilla extract, ground cinnamon, and salt. Set aside.
  • Drain the cooked sweet potatoes in a large colander and transfer to a large bowl. Use a potato masher to mash the sweet potatoes until smooth.
  • Add the brown sugar and egg mixture to the mashed sweet potatoes. Mix thoroughly to combine.
  • Transfer the mashed sweet potato mixture to your prepared casserole dish, using a rubber spatula to spread it into an even layer.
  • In a separate bowl, combine the toasted pecans, all-purpose flour, brown sugar, melted butter, and a pinch of salt.
  • Sprinkle half of the prepared pecan topping over the top of your sweet potatoes followed by approximately 2 cups marshmallows, and finally, the last of the pecan topping.
  • Transfer to the oven and bake for 25-35 minutes, or until the tops of your marshmallows are golden brown and the potatoes are heated through.
