My Sweet Potato Casserole Recipe with Marshmallows is a classic Thanksgiving side dish that just screams Thanksgiving! Fresh sweet potatoes are cooked and mashed with brown sugar and cinnamon, then spread in a casserole dish and topped with ooey-gooey marshmallows!
For year upon year I refused to eat sweet potatoes. I would casually pick away the marshmallow topping, but to actually put the orange stuff in my mouth was just not going to happen. Every Thanksgiving and Christmas it was the same – I’ll pass on the sweet potato casserole thank you very much.
Becoming an adult does funny things to you though, like making you feel all grown up and like you can take on anything – even tasting the aforementioned sweet potato casserole, with marshmallows of course. I did, and I fell in love. This is that casserole and now it’s your turn to fall in love!
HOW TO MAKE SWEET POTATO CASSEROLE
My mom was made the sweet potato casserole with marshmallows for our holiday gatherings each year. She tells me that she basically just mashed up sweet potatoes, added a little salt and threw a bunch of marshmallows on top. According to my dad there were never enough marshmallows – that was the running joke in our family.
To take that casserole completely over the top, I’ve added a few things to sweeten it up and make it extra creamy. This is the only Sweet Potato Casserole recipe that I will eat!
Another note about this casserole – it’s a great Thanksgiving Dinner make ahead recipe! Just refrigerate the potato mixture in the casserole dish overnight and leave off the marshmallows until you’re ready to bake. Add the marshmallows halfway through the baking.
What is the Best Way to Cook a Sweet Potato for a Casserole?
Sweet potatoes are cooked just like a regular russet or other type of potato. For a sweet potato casserole recipe, you don’t need a crispy skin so boiling without the skin is the easiest method to use.
- Bring a large pot of salted water to a boil. Reduce the heat and boil the peeled sweet potatoes until they are nice and tender. It takes about 20 minutes, then you will drain the water off.
- Mash the potatoes with a potato masher (or a hand mixer for no lumps) until smooth. I personally like the lumps as they give a little it of added texture.
Sweet potatoes can also be baked like these Twice Baked Sweet Potatoes or cut up and baked into fries.
How toBuy Sweet Potatoes
Sweet Potatoes are available year round in most places, but in abundance during the fall and early winter. You want to look for small to medium sized potatoes, which are going to be sweet and creamy. The skin of the sweet potato should be firm, smooth and even in color. The darker the skin, the richer in flavor the potato will be.
Are Sweet Potatoes Healthy?
While sweet potatoes have a little more natural sugar than regular potatoes, they are really high in fiber and other nutrients. Sweet potatoes are a good choice for a healthy side dish! They provide essential nutrients, fiber and they taste good too!

Sweet Potato Casserole
Sweet Potato Casserole Recipe is a classic Thanksgiving side dish that just screams Thanksgiving! Fresh sweet potatoes are cooked and mashed with brown sugar and cinnamon, then spread in a casserole dish and topped with ooey-gooey marshmallows!
Yield 8 servings
- 3 pounds sweet potatoes, peeled and roughly cubed
- 1 cup brown sugar
- 3 tablespoons butter, melted
- 1 1/2 teaspoons cinnamon
- 1/2 teaspoon salt
- 1 cup milk
- 2 cups large marshmallows
- Toasted Pecans for garnish (optional)
- Preheat the oven to 375 degrees F.
- Bring a large pot of salted water to a boil. Reduce heat to medium-low and boil sweet potatoes until fork tender; about 20 minutes. Drain.
- Mash the sweet potatoes with a potato masher until smooth. (Use a hand mixer if you want absolutely smooth with no lumps).
- Stir in brown sugar, butter, cinnamon, nutmeg and salt until well combined. Add the milk a small amount at a time to reach desired consistency.
- Spray an 11-inch x 7-inch (medium sized) casserole baking dish with nonstick cooking spray. Spread sweet potatoes evenly in the prepared casserole dish and top with a layer of the marshmallows.
- Bake for 20-25 minutes or until marshmallows are golden brown.
- Allow to cool for 5-10 minutes before serving. Garnish with toasted pecans.
If you find the marshmallows are starting to burn, remove the casserole from the oven sooner. You just need the casserole to be hot throughout, so there's no worry about under-cooking anything.
To make this ahead of time:
Refrigerate the potato mixture in the casserole dish overnight and leave off the marshmallows until you're ready to bake. Add 5-10 minutes to the baking times and add the marshmallows halfway through the baking to avoid burning.
