Gathering Your Sweet Potato Casserole Ingredients
Alright, let’s get down to business and gather everything we need to make this amazing Sweet Potato Casserole. Don’t worry, it’s all pretty standard stuff you probably have in your pantry or can grab easily at the store. The key is getting good quality ingredients, and of course, making sure your sweet potatoes are just right!
Essential Ingredients for Sweet Potato Casserole with Marshmallows
Here’s what you’ll need to grab for the base of our casserole. We’re talking about 4 cups of mashed sweet potatoes – that’s usually about 2 pounds of raw ones. Make sure they’re mashed up nice and smooth! Then, we’ve got 1/2 cup of melted butter for that rich flavor, and 1/2 cup of granulated sugar to sweeten things up. A splash of milk (1/4 cup) makes it creamy, and 2 large eggs, beaten really well, help bind it all together. Don’t forget that teaspoon of vanilla extract for a little warmth, and a dash of cinnamon and nutmeg – they’re non-negotiable for that classic holiday taste! A tiny pinch of salt balances all the sweetness. And of course, the star of the topping: 2 cups of mini marshmallows!
Optional Additions for Extra Flavor
Now, if you want to take this casserole over the top, I highly recommend adding some chopped pecans to the marshmallow topping. They get all toasty and add this wonderful crunch that is just *divine* against the soft sweet potatoes and melty marshmallows. It’s a little extra step, but trust me, it’s SO worth it!
How to Prepare the Best Sweet Potato Casserole with Marshmallows

You’ll be amazed at how simple it is to whip up something this good. Just follow along, and you’ll have a crowd-pleasing side dish in no time!
Step 1: Preheat and Mix
First things first, get that oven preheated to 350°F (175°C). While it’s warming up, grab a big bowl. Toss in your mashed sweet potatoes, that beautiful melted butter, sugar, milk, those beaten eggs, vanilla, cinnamon, nutmeg, and a pinch of salt. Give it all a really good mix until it’s smooth and everything is happy together. No lumps allowed!
Step 2: Baking the Sweet Potato Base
Now, take your greased 9×13 inch baking dish – make sure it’s nicely greased so nothing sticks! Pour that creamy sweet potato mixture into the dish and spread it out evenly. Pop it into your preheated oven and let it bake for about 25 to 30 minutes. You want it to be heated all the way through.

Step 3: The Marshmallow Topping
Once the base is hot and ready, carefully take it out of the oven. Now for the best part! Sprinkle those mini marshmallows all over the top, covering it completely. Pop it back into the oven for just another 5 to 10 minutes. Keep an eye on it – you want those marshmallows to get puffed up, golden brown, and beautifully melted. That’s the magic of this Sweet Potato Casserole with Marshmallows!
Step 4: Serving Your Sweet Potato Casserole

Tips for a Flawless Sweet Potato Casserole with Marshmallows
Making this Sweet Potato Casserole with Marshmallows is pretty simple, but a few little tricks can make it absolutely perfect every single time. You want that creamy texture, that sweet flavor, and those gorgeous, golden marshmallows. Trust me, a little attention to detail goes a long way!
Perfecting the Sweet Potato Mash
Okay, this is super important! For the smoothest, creamiest casserole, really mash those sweet potatoes well. I like to use a potato masher or even a fork. If you have an electric mixer, that works great too! Just make sure there are no big lumps hanging around. It makes all the difference in the final texture.
Achieving Golden Marshmallows
Those marshmallows are the grand finale, right? You want them melted and golden, not burnt! Keep a close eye on them during that last bake. Ovens can be tricky, so if they start looking a little *too* brown too fast, just loosely tent the dish with some foil. You’re aiming for a beautiful, bubbly, golden crust.
Sweet Potato Casserole Variations and Serving
This Sweet Potato Casserole with Marshmallows is fantastic as is, but you know me, I love to play around! It’s so versatile, you can totally make it your own. And figuring out what to serve it with is half the fun!
Creative Sweet Potato Casserole Twists
Want to jazz it up? Try adding a pinch more cinnamon or a dash of ginger to the sweet potato mix. A sprinkle of nutmeg is also lovely! For a really decadent twist, skip the marshmallows and add a streusel topping made from flour, brown sugar, and butter. So yummy!
Delicious Serving Pairings
This casserole is the perfect partner for holiday mains like roast turkey or ham, no question. But honestly, it’s also amazing alongside baked chicken, pork chops, or even a hearty beef roast. It just adds that touch of sweet, comforting goodness to any meal!
