Praline Marshmallow Sweet Potato Casserole

Thanksgiving is almost upon us so I decided to jump on here real quick and share with y’all my family’s favorite holiday side dish – Praline Marshmallow Sweet Potatoes.

When I say this is our favorite holiday side, it really is our favorite of all. It’s almost like a dessert but not quite. It falls somewhere in the middle & it’s oh-so-good.  I’ve not found a sweet potato casserole recipe that I have ever liked better than this one.

It’s really simple to make too. The filling is just sweet potatoes, sugar, eggs, vanilla, & heavy cream – and the praline topping is just butter, flour, pecans, vanilla, & sugar. It’s crazy that something as easy as this tastes so heavenly.

I seriously can’t get enough of this. Give me a spoon and a 9×13 casserole of this – and I’ll be good. My pants won’t fit afterwards but priorities… 😉

Praline Marshmallow Sweet Potato Casserole

Prep Time 5 minutes
Cook Time 30 minutes


  • For the sweet potato part:
  • 4 cups cooked & mashed sweet potatoes about 4-5 large sweet potatoes
  • ½ cup white sugar
  • 2 tablespoons vanilla extract
  • 4 eggs beaten
  • 1 cup heavy cream
  • For the praline topping:
  • 1 stick of butter softened
  • 1 cup packed brown sugar
  • ½ cup all purpose flour
  • 1-1/4 cups chopped pecans
  • 1 teaspoon vanilla extract

Also, you need:

  • 1 cup mini marshmallows or more to your liking


  • Preheat your oven to 350 degrees.
  • Whisk together the cooked (and mashed) sweet potatoes, white sugar, vanilla extract, beaten eggs, & heavy cream. Spread into a casserole dish.
  • In a separate bowl, combine the softened butter, brown sugar, flour, pecans, & vanilla extract. I like to use my hands for this part, it makes it so much easier in my opinion. Crumble the topping all over the sweet potatoes.
  • Bake for 30 minutes. Sprinkle on marshmallows & return to the oven for 3-5 minutes, until your marshmallows are golden.
