🍠 Sweet Potato Casserole with Marshmallows

A classic Thanksgiving side dish - creamy, sweet, and topped with golden marshmallows

Ingredients

  • Sweet potatoes - 3-4 lbs (about 4-5 medium)
  • Butter - 4-6 tablespoons, softened
  • Brown sugar - ½ cup (light or dark)
  • Eggs - 2 large
  • Vanilla extract - 1 teaspoon
  • Ground cinnamon - 1 teaspoon
  • Salt - ½ teaspoon
  • Milk or heavy cream - 2-3 tablespoons (optional)
  • Mini marshmallows - 1-2 cups
  • Pecans or walnuts - ½ cup chopped (optional, for crunchy topping)
  • Ground nutmeg - ¼ teaspoon (optional)

Step-by-Step Method

1. Cook the sweet potatoes

Choose one method:

  • Roasting (recommended): Preheat oven to 400°F. Prick sweet potatoes with a fork, place on baking sheet, roast 45-60 minutes until tender
  • Boiling: Peel and cut into chunks, boil 15-20 minutes until fork-tender

Let cool slightly, then remove skins if roasted

2. Mash the sweet potatoes

Mash the cooked sweet potatoes until smooth. You can use a potato masher, fork, or food processor for extra smoothness.

3. Mix the casserole base

In a large bowl, combine:

  • Mashed sweet potatoes
  • 4-6 tbsp softened butter
  • ½ cup brown sugar
  • 2 eggs (beaten)
  • 1 tsp vanilla extract
  • 1 tsp ground cinnamon
  • ½ tsp salt
  • 2-3 tbsp milk or cream (optional, for creaminess)
  • ¼ tsp nutmeg (optional)

Mix until well combined and smooth.

4. Transfer to baking dish

Spread the mixture into a greased 9x13 inch baking dish or 2-quart casserole dish. Smooth the top.

5. Bake

Bake at 350°F for 25-30 minutes until the edges are bubbly and the center is set.

6. Add marshmallows and finish

Remove from oven and top with:

  • 1-2 cups mini marshmallows (spread evenly)
  • Optional: ½ cup chopped pecans or walnuts

Return to oven and bake 5-10 minutes until marshmallows are golden brown and puffy. Watch closely - they can burn quickly!

Make-Ahead Tips

  • Day before: Prepare the casserole base, cover, and refrigerate. Add marshmallows and bake on Thanksgiving day
  • Morning of: Bake the base, let cool, then add marshmallows right before serving
  • Reheating: Can be reheated at 350°F for 10-15 minutes, but marshmallows may not look as perfect

Pro Tips

  • ✓ Roasting sweet potatoes (vs boiling) gives better flavor and texture
  • ✓ Don't overmix - just until combined for best texture
  • ✓ Use mini marshmallows for even coverage and better browning
  • ✓ Watch marshmallows closely - they go from golden to burnt quickly!
  • ✓ If marshmallows brown too fast, tent with foil
  • ✓ Pecans add great crunch - toast them first for extra flavor

Variations

  • Pecan topping: Mix ½ cup chopped pecans with 2 tbsp butter and 2 tbsp brown sugar, sprinkle over marshmallows
  • Less sweet: Reduce brown sugar to ⅓ cup
  • Extra creamy: Add ¼ cup heavy cream instead of milk
  • Spiced: Add ⅛ tsp ground cloves or allspice
