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


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)


  1. Preheat your oven to 350 degrees.
  2. Whisk together the cooked (and mashed) sweet potatoes, white sugar, vanilla extract, beaten eggs, & heavy cream. Spread into a casserole dish.
  3. 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.
  4. Bake for 30 minutes. Sprinkle on marshmallows & return to the oven for 3-5 minutes, until your marshmallows are golden.
