We love this sweet potato casserole! It’s topped with homemade toasted marshmallow fluff , and the sweet potatoes are baked rather than boiled, making it an easy sweet potato casserole recipe! This holiday classic has been a family favorite for many years!
This dish is a staple at our Thanksgiving table! What I love about this recipe is that the sweet potatoes are baked rather than boiled. This eliminates having to peel, chop and boil them.
Furthermore, when sweet potatoes are baked they become even sweeter! It also makes mashing so much easier. It’s just easier all around and the flavor is perfect. Creamy sweet potatoes are a classic thanksgiving side dish.
We’ve always topped ours with marshmallows growing up, but I love nothing more than spreading a fluffy, homemade marshmallow fluff over the top! Torch it with a kitchen torch and it not only looks gorgeous but tastes even better!
You can also use marshmallows too, mini marshmallows or large work great. Simply add an even layer of marshmallows over the top of the sweet potatoes (once the casserole is done) and place in the oven for 5-10 minutes until the marshmallows are gooey and toasted!
How to Make Sweet Potatoe Casserole
This casserole is made with only 5 ingredients! Here is everything you need to make this recipe. The full recipe is in the recipe card below.
Supplies
You’ll need a few supplies to make this classic side dish:
- Baking Dish or Casserole Dish
- Baking Sheet
- Potato Masher or Hand Mixer
- Tin Foil
- Large Bowl
Ingredients
Sweet Potatoes – You’ll need 5 large sweet potatoes for this recipe. We use whole sweet potatoes and pop them right in the oven!
Brown Sugar – This adds all of the sweetness to the sweet potatoes. You can use dark brown sugar or light brown sugar.
Butter – This adds so much flavor to the sweet potato mixture! Use good quality butter for the best flavor.
Heavy Cream – The cream gives the casserole a creamy texture.
Vanilla Extract – Add flavor and gives more depth to the dish. Use pure vanilla extract.
Salt – Enhances the flavors in the recipe.
Fluffy Marshmallows or Marshmallow Fluff – Either of these will work to add a delicious marshmallow topping over the sweet potatoes!
Directions
How to Bake a Sweet Potato
Preheat the oven to 425 degrees Fahrenheit
Rinse and pat dry the potatoes.
Line a baking sheet with foil and place the potatoes on the aluminum foil to bake.
Bake until tender for about 50 minutes. You want them to be extra soft.
Cut them open and scoop out the sweet potato and place them in a bowl, leaving the skin behind.
Mash the sweet potatoes with butter, sugar, salt, and heavy cream while they’re hot.
Bake until tender for about 50 minutes. You want them to be extra soft.
Cut them open and scoop out the sweet potato and place them in a bowl, leaving the skin behind.
How to Mash Potatoes
If you don’t have a potato masher, use a fork to get them as smooth as possible. If you want them really smooth add them to a food processor.
We don’t like them too smooth though as the texture is nice for a casserole.
Boiled Potatoes vs. Baked Potatoes
There are two ways of getting soft sweet potatoes. You can peel, chop, and then bring them to a boil in a large pot. Then they’re drained and mashed. However, we find the easiest way is to bake them.
You don’t have to peel or chop and when baked they are even sweeter!
For this method, you simply poke holes in the potatoes, then place them on a baking sheet lined with tin foil and bake until super soft. Then slice opens the top and scoops out the inside of the sweet potato.
Add More Flavors to the Sweet Potatoe Casserole
Bourbon – You can even add in a splash of bourbon or any liquor to give the sweet potatoes an extra kick! Spices like cinnamon and nutmeg are also great in a sweet potato casserole.
Nuts – Top the casserole with walnuts or pecans for a crunch or add a streusel topping over the top of the casserole.
Orange Juice and Orange Zest – Give the dish some citrus notes with orange juice. It will add so much yummy flavor to the dish! Just add a tablespoon of zest or juice to the recipe.
Cardamom – If you’re a fan of this fall spice, add a 1/2 teaspoon for an incredible flavor. We use it in our apple cider donuts and they are amazing!
Spread the homemade marshmallow fluff over the mashed sweet potatoes.
Marshmallow Topping
There are two ways you can add toasty marshmallows to this dish!
Marshmallow Fluff – Spread the homemade marshmallow fluff over the mashed sweet potatoes. Using a kitchen torch, torch the marshmallow fluff until it’s toasty!
Marshmallows – Place large marshmallows or mini marshmallows over the top of the mashed sweet potatoes before baking. They will become gooey marshmallows and taste so good in this classic sweet potato casserole.
Make this dish ahead of time!
We all know how hectic the kitchen gets on Thanksgiving and there is nothing better than a recipe that can be prepared in advance, checking another thing on the Thanksgiving menu! To do this, prepare the casserole and place it in the baking dish you’ll be baking them in. Hold the marshmallows, you will add these right before baking.
Wrap the casserole with plastic wrap and store it in the refrigerator for up to two days. When you’re ready to bake, remove the wrap and add the marshmallows. Bake as the recipe calls. You can also make the marshmallow fluff ahead of time too!
In this case, you’ll wait to add the fluff until after they’re baking then use a kitchen torch to make them nice and toasty!
How to Store
If you have any leftovers, they can be stored in an airtight container for two days. Reheat in the microwave or oven. If you want to keep them longer, sweet potato casserole can be frozen for up to two months. Let it thaw overnight in the refrigerator then reheat.
