Ingredients

Scale

Sweet Potato Mixture

  • 4 lb sweet potatoes
  • 1/2 cup unsalted butter, at room temperature
  • 3/4 cup packed light brown sugar
  • 1/2 cup whole milk, room temperature
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 tsp salt
  • 1/4 cup pecans, chopped (for folding in)

Topping

  • 2 cups miniature marshmallows
  • 1/4 cup chopped pecans (for topping)

Instructions

  1. Prepare Sweet Potatoes: Peel and cut sweet potatoes into 1-inch cubes. Place in a large pot and cover with cold water. Bring to a boil over high heat, then reduce to simmer and cook for 10-15 minutes until tender. Drain thoroughly and press gently to remove excess moisture to avoid sogginess.
  2. Preheat Oven and Prepare Dish: Preheat oven to 375°F (190°C). Spray a 9×13-inch casserole dish with cooking spray and set aside.
  3. Mix Sweet Potato Base: While potatoes are warm, transfer to a large mixing bowl. Add softened butter, brown sugar, room-temperature milk, eggs, vanilla, and salt. Using an electric mixer on medium speed, blend until smooth and creamy, about 2-3 minutes. Gently fold in 1/4 cup chopped pecans by hand.
  4. Assemble Casserole: Spread the sweet potato mixture evenly into the prepared dish with a spatula. Scatter miniature marshmallows evenly over the top, leaving small gaps. Sprinkle the remaining 1/4 cup chopped pecans over the marshmallows for added crunch.
  5. Bake: Place the casserole in the oven and bake for 25-30 minutes, until marshmallows are golden brown and edges bubble slightly. Check at 25 minutes for doneness.
  6. Rest and Serve: Remove from oven and let rest for 5 minutes to set. Serve warm directly from the dish for the best texture and flavor.

Notes

  • Pressing out excess moisture from cooked sweet potatoes is crucial to prevent a watery, soggy casserole.
  • Using room-temperature milk helps achieve a smoother, creamier sweet potato mixture.
  • Leaving small gaps between marshmallows allows some to brown unevenly for a nice texture contrast.
  • Toasted pecans add a delicious crunch and nutty flavor that complements the sweet potatoes and marshmallows perfectly.
  • This dish is best served warm and is a classic addition to holiday meals like Thanksgiving.
