I can’t believe that October is almost over, it feels like we were just saying goodbye to summer! I’m already thinking about Thanksgiving, it’s one of my favorite holidays. Let me tell you: this sweet potato casserole with marshmallows? Is the best sweet potato casserole I’ve ever had. It’s a MUST for the holidays, to be honest, my kids ask for it year round.
This easy sweet potato casserole has the best of both worlds with a crunchy pecan streusel topping AND a generous amount of mini marshmallows. The mashed sweet potato mixture underneath all that topping is just lightly sweetened to create the perfect balance between savory and sweet.
How do you cook sweet potatoes?
I like to roast whole sweet potatoes for this recipe. It’s super easy and you can just scoop the potatoes out of their skins, so there’s no peeling involved! Simply prick the potatoes with a fork, then place them on a sheet pan. Bake for 45-60 minutes or until the potatoes are tender and you’ll be ready to go! You also have the option of boiling or steaming cubed and peeled sweet potatoes.
How do you make sweet potato casserole?
This recipe starts with the sweet potatoes. I prefer to mash my sweet potatoes with a hand masher for a more rustic texture, but you can definitely puree the sweet potatoes in a food processor if you prefer them to be on the smooth side. Another option is to beat them with a mixer until they’re light and fluffy.
The sweet potatoes are mixed with brown sugar, maple syrup, cinnamon and butter. Aren’t you hungry just thinking about it? The casserole is topped with an easy pecan streusel and then goes into the oven. The marshmallows don’t go on until the very end, otherwise they could burn. All you do from there is serve and enjoy!
Tips for sweet potato casserole
- Not a fan of marshmallows? You can leave them off entirely and still have a fabulous dish.
- If you don’t like pecans, try walnuts or almonds instead.
- This recipe can easily be doubled or tripled if you’re looking to serve a large crowd.
- I typically use light brown sugar because I always have it on hand, but dark brown sugar will also work just fine.
- The recipe will work with canned sweet potatoes, but freshly cooked potatoes have a better flavor and texture. If you’re using canned sweet potatoes, make sure they don’t contain any sugar.
- You can arrange your marshmallows in a decorative pattern like I’ve done here, or simply sprinkle them over the top. It’s delicious either way.
Can you make sweet potato casserole in advance?
The number one question I’m asked about this recipe is, can it be made in advance? Yes, you can assemble this casserole the day before you plan to bake it. Simply cook and mash the potatoes, then add the streusel topping, cover and refrigerate.
You may need to add 7-10 minutes to the bake time if you’re starting with a cold casserole. I almost always assemble it early on so that my time is freed up to work on other holiday dishes on the day of the big event.
This recipe has gotten countless rave reviews, your family is sure to love it too!
