Fresh baked sweet potatoes are mashed together with butter and maple syrup and baked until bubbly. Then they’re topped with mini marshmallows and candied pecans and baked again until perfectly browned.

While this casserole looks so fancy it’s actually easy to prepare. You can place the marshmallows and pecans in any design you like. No need to follow my design! But if you want to I’ve got all the directions in the recipe card.

What do I need to Make this Candied Pecan Marshmallow Sweet Potato Casserole?

How can I make this Sweet Potato Casserole Easier?

You can skip making the candied pecans. They add so much flavor to this casserole though I think they’re worth it! BUT Make them ahead of time if you want to save some time on the day you’re making this dish. Or BUY them!!

You can ALSO boil the sweet potatoes instead of baking them. This saves time as well as oven space if that’s a concern.

I recommend making this dish UP through the step of making the mashed potatoes. They can be stored in the fridge until you’re ready to spread them in a baking dish. Bake and top as usual.

I don’t recommend making and baking this casserole completely with the pecans and marshmallows and then trying to reheat it to serve. The marshmallows will catch on fire.

How to Reheat Leftover Sweet Potato Casserole?

Be careful if you’re reheating this casserole again the marshmallows are going to cause you trouble. I’d say take the cooked marshmallows off and reheat it without them. You can add them back after reheating if you like. OR add fresh mini marshmallows and reheat until they brown lightly.
