Ingredients

  • 2 ½ pounds sweet potatoes (peeled, cut into 1-inch cubes)
  • ¼ cup light brown sugar (packed)
  • ¼ cup unsalted butter (softened)
  • 1 teaspoon salt
  • 1 teaspoon vanilla extract
  • ½ cup pecans (chopped, divided)
  • 2 cups mini marshmallows

Instructions

  1. Step 1: Preheat your oven to 375°F and grease a 9 x 13-inch casserole dish to prevent sticking.
  2. Step 2: Place the sweet potatoes into a large pot of boiling water.
  3. Step 3: Reduce the heat to low and let the sweet potatoes simmer until tender, about 10 to 15 minutes.
  4. Step 4: Drain the sweet potatoes and transfer them to a large mixing bowl. Mash them together with the brown sugar, softened butter, salt, and vanilla extract until smooth and well combined.
  5. Step 5: Fold in ¼ cup of the chopped pecans, then spread the sweet potato mixture evenly into the prepared casserole dish. Top with the mini marshmallows and sprinkle the remaining pecans over the top.
  6. Step 6: Bake in the preheated oven for 20 to 25 minutes, or until the casserole is bubbly and the marshmallows are golden brown.

Tips & Variations

  • For a richer flavor, try adding a pinch of ground cinnamon or nutmeg to the sweet potato mash before baking.
  • If you prefer a crunchier topping, toast the pecans lightly before adding them to the casserole.
  • Swap mini marshmallows for chopped large marshmallows if mini ones are unavailable.
  • To make it nut-free, simply omit the pecans or substitute with toasted coconut flakes.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm the casserole in the oven at 350°F until heated through, about 15 minutes.

FAQs

Can I make this casserole ahead of time?

Yes, you can prepare the mashed sweet potatoes and assemble the casserole a day in advance. Cover it tightly with foil and refrigerate. Bake it the next day, adding a few extra minutes to the baking time if chilled.

Can I use frozen sweet potatoes instead of fresh?

Frozen sweet potatoes can be used, but be sure to thaw and drain any excess moisture before mashing to avoid a watery casserole.
