Ingredients

Scale

Sweet Potato Base

  • 2 1/2 lb sweet potatoes, peeled and cut into 1-inch pieces
  • 1/2 tsp pure vanilla extract
  • 1/4 cup unsalted butter (preferably Kerrygold for richness)
  • 1 1/2 tsp salt
  • 1/4 cup pecans, finely chopped
  • 1/4 cup brown sugar, firmly packed

Topping

  • 2 cups mini marshmallows (optional but recommended)
  • 1/4 cup pecans, finely chopped
  • Nonstick cooking spray

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 375°F (190°C). Generously spray a 9×13 inch baking dish with nonstick cooking spray, ensuring the bottom and sides are coated to prevent sticking and ease cleanup.
  2. Boil Sweet Potatoes: Place the peeled and cut sweet potatoes in a large pot and cover with cold water. Bring to a boil over high heat and cook for 15-20 minutes until the potatoes are fork-tender and easily pierced. Drain in a colander and let cool for about 5 minutes to make mashing easier without breaking apart completely.
  3. Mash and Mix Sweet Potatoes: Transfer the cooled sweet potatoes to a large mixing bowl. Add brown sugar, unsalted butter, salt, and vanilla extract. Mash the mixture to your desired consistency, preferably leaving it slightly chunky to maintain texture. Fold in 1/4 cup of finely chopped pecans evenly throughout the mixture.
  4. Assemble Casserole: Evenly spread the sweet potato mixture in the prepared baking dish, smoothing the top with a spatula. Sprinkle the remaining 1/4 cup of chopped pecans evenly over the surface, then arrange the mini marshmallows on top in a single layer, spacing them slightly for optimal puffing and browning during baking.
  5. Bake: Place the casserole in the preheated oven and bake for 20 minutes until the marshmallows are puffed up and golden brown. Keep a close eye during the final few minutes to avoid burning as marshmallows can quickly go from golden to charred.
  6. Rest and Serve: Remove the casserole from the oven and let it rest for 5 minutes to allow it to set slightly, making it easier to portion and serve.

Notes

  • Using pure vanilla extract enhances the flavor over imitation vanilla.
  • Leaving the sweet potato mash slightly chunky adds pleasant texture to the dish.
  • Spraying the baking dish thoroughly prevents sticking and simplifies cleanup.
  • Keep a close watch on marshmallows during baking to avoid burning.
  • Optional marshmallows can be omitted or replaced with a streusel topping for a less sweet variation.
  • This dish pairs wonderfully with roasted meats and green vegetable sides for holiday meals.
