There’s something magical about the way Sweet Potato Casserole with Marshmallows brings everyone to the table. It’s not just a dish—it’s a warm hug in casserole form, the kind of comfort food that makes holidays feel like home. I’ll never forget the first time I tried making it myself, standing in my tiny apartment kitchen with my grandmother’s handwritten recipe card propped against the flour canister. The scent of cinnamon and caramelizing marshmallows took me right back to childhood Thanksgivings, where we’d all crowd around waiting for that first golden-brown bite.
This recipe connects generations in our family. My great-aunt always claimed her secret was a splash of orange juice to brighten the sweetness, while my mom insisted on an extra pinch of cinnamon “for warmth.” When I finally perfected my version, I realized what makes Sweet Potato Casserole with Marshmallows so special isn’t just the creamy potatoes or the toasted topping—it’s how one simple dish can hold so many memories. Now when I make it, my kids press their noses against the oven door, just like I did, watching those marshmallows puff into golden clouds. Some traditions are too sweet to lose.
Why You’ll Love This Sweet Potato Casserole with Marshmallows
Oh my goodness, where do I even start? This dish has been stealing the show at our family gatherings for years, and here’s why you’re going to adore it too:
- That creamy sweet potato base is like velvet on your spoon – smooth, rich, and just sweet enough without being cloying. I always sneak an extra spoonful before adding the topping!
- The golden marshmallow crown transforms under the broiler into this magical combination of crispy, gooey, and lightly caramelized perfection. It’s like s’mores met Thanksgiving and had the best baby ever.
- Couldn’t be easier to make – just boil, mash, mix and bake. Even my teenager can handle this one when he’s “helping” in the kitchen (read: hungry and impatient).
- It’s the ultimate crowd-pleaser that bridges generations. My picky nephew, gourmet-foodie aunt, and everything-in-between family members all come back for seconds.
But fair warning – you might become known as “the sweet potato casserole person” at every potluck from now on. Not that I’m complaining – it’s a title I wear proudly!
Ingredients for Sweet Potato Casserole with Marshmallows
Okay, let’s gather our goodies! Here’s what you’ll need to make this dreamy casserole (and trust me, the simple ingredients work magic together):
- 5 sweet potatoes – peeled and sliced (about 2 lbs total – and yes, fresh makes all the difference! No canned stuff here)
- 1/2 cup packed brown sugar – go for dark brown if you have it – that molasses depth is everything
- 1/4 cup butter – real butter, room temperature (my grandma would haunt me if I suggested margarine)
- 3 tablespoons orange juice – fresh squeezed if you can, but bottled works in a pinch
- 1 pinch ground cinnamon – just a whisper to warm things up
- 1 (10.5 oz) bag miniature marshmallows – the star of the show! I like the minis because they layer beautifully
That’s it! Simple, right? I sometimes play around with adding a splash of vanilla or a sprinkle of nutmeg – but this classic combo is perfection. Oh! And if you’re craving more sweet potato goodness, you’ve gotta try my sweet potato pie bars next – they’re dangerously addictive.
How to Make Sweet Potato Casserole with Marshmallows
Alright, let’s get cooking! This sweet potato casserole comes together so easily, you’ll wonder why you don’t make it year-round. Just follow these simple steps, and you’ll have a golden, gooey masterpiece in no time.
First things first – preheat that oven to 350°F (175°C). While it’s heating up, grab your sweet potatoes and get them boiling. I like to cut them into even slices (about 1-inch thick) so they cook uniformly. Toss them in a big pot, cover with water, and bring to a boil. Let them bubble away for about 15 minutes – you’ll know they’re ready when a fork slides in effortlessly.
Drain those beauties and mash them right in the pot (less dishes to wash – score!). Now for the fun part – add your brown sugar, butter, orange juice, and that magical pinch of cinnamon. Here’s my secret: use an electric mixer to blend everything until it’s silky smooth. It makes all the difference in texture!
Spread your sweet potato mixture into a 9×13-inch baking dish – I like to use a rubber spatula to get it nice and even. Now comes the moment we’ve all been waiting for – the marshmallows! Sprinkle them generously over the top. Don’t be shy – this is where the magic happens.
Pop it in the oven for 25-30 minutes. Keep an eye on it after 20 minutes though – those marshmallows can go from golden to charcoal faster than you can say “Thanksgiving dessert”! When they’re puffed up and beautifully browned, it’s ready.
The hardest part? Waiting five minutes before diving in (but trust me, it’s worth it to avoid burning your tongue!).
Pro tip: If you love sweet potatoes as much as I do, you should definitely check out my sweet potato lentil soup for another cozy meal idea. But for now, grab a spoon and enjoy this marshmallow-topped wonder – just try not to eat the whole pan yourself!
Tips for Perfect Sweet Potato Casserole with Marshmallows
Listen, after making this casserole more times than I can count, I’ve learned a few tricks that’ll take yours from good to “can I get your recipe?” status:
- Fresh is best – I know canned sweet potatoes are tempting, but honestly? The texture and flavor of fresh makes all the difference. Just peel, chop and boil – it’s worth the extra 10 minutes, promise!
- Watch those marshmallows like a hawk – Set a timer for 20 minutes and peek in. They can go from perfect golden to “oh no!” in seconds. If they’re browning too fast, just loosely tent with foil.
- Taste before baking – Sweet potatoes vary in natural sweetness. Give your mixture a quick taste and add a bit more brown sugar if needed (I won’t tell).
- Serve warm, not hot – Let it sit 5-10 minutes after baking so the marshmallows set slightly. That way you get that dreamy pull when scooping versus lava-hot strings everywhere!
Oh! And if you’re feeling fancy, sprinkle some chopped pecans on top before baking for extra crunch. But honestly? The classic version is pretty perfect as is.
Serving Suggestions for Sweet Potato Casserole with Marshmallows
This casserole is basically the social butterfly of holiday side dishes – it gets along with everyone at the table! Of course it’s perfect with classic roast turkey (those sweet and savory flavors were made for each other), but don’t stop there. It’s equally dreamy next to a honey-glazed ham or even a simple roasted chicken on chilly weeknights. For a full feast, pair it with my maple-glazed Brussels sprouts for some veggie balance, and maybe a crisp green salad to cut through all that cozy sweetness. Just make sure to serve it while those marshmallows are still slightly warm and gooey – nobody likes left gets between your guests and that first magical bite!
Storage and Reheating Instructions
Oh honey, we both know there’s rarely leftovers with this casserole – but if you somehow end up with extra, here’s how to keep it delicious! First, let it cool completely (those marshmallows hold heat like crazy). Cover tightly with foil or transfer to an airtight container – it’ll keep in the fridge for 3-4 days. For longer storage, freeze before adding marshmallows (they get weird when frozen). To reheat, 350°F for 15-20 minutes works magic – just add fresh marshmallows in the last 5 minutes if your frozen batch didn’t have them. The sweet potatoes may separate a bit, so give them a quick stir before topping. Pro tip: single servings reheat beautifully in the microwave at 50% power for about 90 seconds – just enough to get that gooey texture back without turning your marshmallows into sticky lava!
Sweet Potato Casserole with Marshmallows FAQs
I get asked about this casserole more than any other dish at holiday time! Here are the answers to all those burning questions (pun totally intended):
Can I use canned sweet potatoes instead of fresh?
Listen, I won’t lie – fresh sweet potatoes give the best texture and flavor. But in a pinch? Sure, you can use canned. Just drain them well and reduce the orange juice slightly since canned ones are already softer. You’ll need about 3 cups mashed. But between you and me? Fresh is worth the extra effort!
Help! My marshmallows keep burning!
Oh honey, I’ve been there! The trick is to tent loosely with foil after 20 minutes if they’re browning too fast. Also, position your rack in the middle of the oven – too close to the top element spells disaster. And for Pete’s sake, set that timer! Marshmallows go from golden to charcoal in about 90 seconds flat.
Can I make this ahead of time?
Absolutely! Prepare the sweet potato base up to 2 days ahead and refrigerate. When ready to bake, let it come to room temp (about 30 minutes), top with marshmallows, and bake as directed. The marshmallows won’t be quite as fluffy, but still delicious. Just add 5 extra minutes to the bake time since it’s starting cold.
What’s the best way to reheat leftovers?
Microwave at 50% power in short bursts works in a hurry, but for best results? Pop it back in a 350°F oven for 10-15 minutes. The marshmallows won’t be quite as perfect, but they’ll still taste amazing. Pro tip: sprinkle a few fresh mini marshmallows on top before reheating for that just-baked look!
Can I freeze this casserole?
You can freeze the sweet potato base (without marshmallows) for up to 3 months. Thaw overnight in the fridge, then bake as usual with fresh marshmallows. Frozen marshmallows get weirdly chewy – trust me, I learned this the hard way after Thanksgiving 2017!
Nutritional Information
Just a quick note, friends – these nutritional estimates are about as reliable as my kids’ promises to clean their rooms!
