I don’t care what anyone says; sweet potato casserole is essential for Thanksgiving dinner! I love it in all forms, but Sweet Potato Casserole with Marshmallows is nostalgic and delicious– and who doesn’t want to eat dessert with your meal?

Creamy, sweet, and spicy sweet potatoes are topped with golden, crunchy marshmallows for a classic Thanksgiving side dish!

Sweet Potatoes vs Yams

Let’s settle the debate right now. Yams and sweet potatoes are not the same thing! Yams have dark skin that has more of a rough bark-like texture, and inside has the texture of a normal potato. They also aren’t as sweet as a sweet potato.

Most confusingly of all, in most of the US, the words yams and sweet potatoes are used interchangeably, especially during Thanksgiving. If you’re looking to make candied yams for the holidays, you’re actually making sweet potatoes!

If you accidentally buy fresh yams, you’re going to be disappointed. Your casserole won’t turn out as sweet or creamy as it usually does.

Look for long, pointed potatoes with orange-colored, smooth skin. As long as your sweet potatoes look like sweet potatoes, you’ll be good!

Ingredients for Sweet Potato Casserole

How to Make Sweet Potato Casserole with Marshmallows

Making sweet potato casserole from scratch is not hard! It just requires a few steps.

Step 1: Boil your potatoes

Boil your potatoes until they are fork-tender. This should take about 15 minutes or so. Drain the potatoes and add them to a large bowl.

Step 2: Season and mash

Add your butter, orange juice, brown sugar, pumpkin pie spice, and cinnamon to the bowl with the potatoes. Mash with a potato masher or hand mixer. I like to use a hand mixer because it goes so quick.

Step 3: Assemble

Add your sweet potatoes to a baking dish and top with marshmallows.

Step 4: Bake

Bake your casserole for about 23 minutes, or until everything is warmed through and the marshmallows are browned. If the marshmallows get too brown, you can cover the casserole with foil.

Can I Make Sweet Potato Casserole with Marshmallows Ahead?

Yes, you can make this ahead of time and cook it later! Make this through step 3, but don’t add the marshmallows on top. Refrigerate the sweet potato mixture for up to 3 days. When you want to make it, just take it out of the fridge, add your marshmallows on top, and bake. You might need to add a couple of extra minutes to your baking time, and if the marshmallows get too brown, you can cover the casserole with foil.
