Classic Sweet Potato Casserole Recipe

Nothing screams “Thanksgiving” like sweet potato casserole topped with lightly toasted marshmallows and pecans! When I think of classic Thanksgiving side dishes, I can’t think of anything more traditional.  I used my favorite Sweet Potato Casserole with Pecan Topping recipe as jumping off point when creating this recipe for Thanksgiving sweet potato casserole. It’s been a reader and fan favorite for years now! Being that it’s such a fan favorite due to those sweet, creamy, and tender sweet potatoes, topped with the most lovely buttery pecan crumble topping for a texture contrast that I personally adore, it was about time for a marshmallow-topped rendition. Today’s recipe is virtually the same, but with a marshmallow twist. My daughter says they’re her favorite part!

How to Make Sweet Potato Casserole with Marshmallow Topping

As I mentioned, I used my favorite Sweet Potato Casserole recipe as the base, and then added marshmallows. If it ain’t broke, don’t fix it!

Make-Ahead Instructions

You can assemble the entire casserole the night before, cover it tightly with foil, and refrigerate it until ready to bake. I suggest letting the casserole sit at room temp on your counter for 30 to 45 minutes before baking if you have refrigerated it overnight so that you don’t need to extend the baking time at all.

All of my sweet potato recipes here!  In the freezer: Store airtight for up to 4 months. However, I recommend freezing it without the marshmallows on top for best results.  To reheat: First, let it sit at room temp for at least 15 to 30 minutes if you can plan ahead. Then, you can reheat the casserole in either the microwave or the oven. Reheat in 30-second bursts in the microwave. Reheat in a 325ºF oven for 15 to 20 minutes. Tried this recipe? Leave a review!
