Tessa’s Recipe Rundown
Taste: I love the hint of maple and nutmeg in the filling. Both toppings feel like you’re eating dessert for dinner in the best possible way!
Texture: The filling is rich, soft, and creamy without being too whipped. Of course, the texture of the topping depends on which spoonful you go for – crunchy pecan topping or gooey marshmallow.
Ease: Very easy, even when using fresh sweet potatoes.
Pros: You get the best of both worlds and the filling is scrumptious.
Cons: None!
Would I make this again? Absolutely – every Thanksgiving, Friendsgiving, and Christmas!

My favorite Thanksgiving side dish has been Sweet Potato Casserole for as long as I can remember.
That’s probably because the casserole is basically dessert disguised as dinner. That’s something I can ALWAYS get on board with. I’m particularly fond of that buttery brown sugar pecan topping. However, I know many people and families prefer the marshmallow topping.
That’s why this is such a crowd-pleasing recipe. You can offer your Thanksgiving guests BOTH, so everyone is happy! You can even put the best of both worlds on your own plate if you can’t decide.

The casserole I grew up eating relied on canned yam puree, which does cut the oven time down, but it also cuts the flavor. Using fresh sweet potatoes is a total game-changer.
Reader Love
I made this last year for Thanksgiving, and it was a big hit! Even my picky son loved it. I’m definitely making it again this year. The maple syrup and the 2 different toppings are incredible. My mouth is watering just thinking about it.

This casserole is the perfect side dish to please everyone at your Thanksgiving table. Add my delicious Apple & Sausage Stuffing, easy Cheesy Green Bean Casserole with Bacon, and buttery, soft Ultimate Dinner Rolls, and you’re all set for Turkey Day!

How to Make Sweet Potato Casserole
Do I Have to Use Fresh Sweet Potatoes?
Yes. I know it’s a bit of extra work, but I promise, it’s so worth it! If timing is an issue for you, bake your sweet potatoes ahead of time, scoop out the inner flesh, and refrigerate inside an airtight container until you’re ready to make the potato casserole.
If you buy too many sweet potatoes, try out Brown Butter Sweet Potato Pie or Sweet Potato Dinner Rolls to use up the rest!
Sweet Potatoes vs. Yams
Although often labeled interchangeably in grocery stores, sweet potatoes and yams are different. We are using sweet potatoes in this recipe. The Spruce Eats has a terrific explanation of the differences between these two vegetables, so check that out if you’re interested!
What Type of Maple Syrup Should I Use?
Be sure to use real maple syrup, not maple-flavored syrup meant for pancakes. I know some real maple syrups can get pricey, so check out Trader Joe’s maple syrup – it’s good quality for a reasonable price.
What Type of Milk for Sweet Potato Casserole?
I always prefer to use whole milk, but 2% should work okay – it may just make your sweet potato casserole a little less rich and creamy.
I haven’t tried any dairy-free milks here, but just note that may alter the flavor and texture.
What Type of Pan Should I Use for Sweet Potato Casserole?
- This recipe was written to use a 9×13-inch baking pan.
- I recommend a ceramic pan like this one, for the prettiest table presentation.
- Feel free to use a glass or even a disposable pan, as long as they’re similarly sized.
- Be cautious of the pan’s material if you’re planning to make ahead, as not all pans can safely go from freezer to oven, or even fridge to oven.
Can You Make Sweet Potato Casserole Ahead of Time?
Yes! Once the casserole is assembled but just before baking, you can cover and refrigerate for up to 2 days. Add toppings just before baking. If baking straight from the fridge, add a few minutes to the baking time.
If you need to prep further in advance, check out my freezing instructions just below.
How to Freeze Sweet Potato Casserole
- Assemble the casserole in a heat-safe and freezer-safe pan but don’t add the toppings yet.
- Wrap the pan in plastic wrap. Cover with tin foil, label, and date. Freeze for up to 4 months.
- When you’re ready to bake, remove plastic and foil, add the toppings, and bake for about 45 minutes from frozen.
- If using a glass pan, allow to defrost overnight in the fridge before adding the toppings and baking, adding a few minutes to the bake time if baking straight from the fridge.
How to Store Leftovers
Store any leftovers in an airtight container in the fridge for up to 5 days.

Crowd Pleasing Sweet Potato Casserole
Ingredients
For the casserole:
- 4 large sweet potatoes
- 1 cup milk
- 1/2 cup pure maple syrup
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 teaspoon fine salt
- 1/8 teaspoon ground nutmeg
For the toppings:
- 1/4 cup (32 grams) all-purpose flour
- 3 tablespoons (44 grams) butter, at room temperature
- 1/2 cup (100 grams) brown sugar
- 1/2 cup (70 grams) pecans (or more, depending on preference), chopped
- 1 1/2 cups miniature marshmallows
Instructions
- Preheat the oven to 400°F. Pierce the potatoes all over with a fork and place on a foil or parchment-lined rimmed baking sheet. Bake until they are tender on the inside, about 45 minutes. Reduce oven temperature to 350°F. Let the potatoes cool slightly, then slice open and scoop the flesh into a large bowl, discarding the skins. Mash with a potato masher, being careful not to over-mash. Add the milk, maple syrup, eggs, vanilla, salt, and nutmeg and stir until just combined.
- In a small bowl, combine the flour and butter, cutting the butter into the flour with the back of a fork. Add the brown sugar and pecans and stir until combined.
- Spread the potato mixture into a 13 by 9-inch pan (or similarly sized baking dish). Sprinkle the pecan mixture in diagonal rows over the sweet potatoes, leaving a 1 1/2-inch gap between rows. Bake at 350°F until golden brown on top, about 30 minutes. Remove from oven and gently place the marshmallows between the rows of the pecan mixture. Bake for an additional 10 minutes, or until the marshmallows are just golden brown. Serve.

I used this recipe for Thanksgiving with only one small tweak. Instead of nutmeg, I used a tablespoon of baking spice. It well so well received that I had to make a second batch for leftover night! Thanks for the recipe!
Hi does it matter what type of milk I use? Whole, 1% , etc. thanks!
Hi Sarah! We always recommend whole milk for best results, but 2% should work if that’s all you have. Let us know what you think once you have given this casserole a try!
I’ve made this twice, today being one of the times, I don’t use the maple syrup or nutmeg, I put a little extra brown sugar in the potatoes and a pinch of cinnamon! My son doesn’t eat sweet potatoes and he loved this version, it really is delicious! Thank you for the recipe❤️
My go to thanksgiving side.
Definitely a crowd pleaser!! I made first 2 years ago, now this is the requested dish for the holidays! so good!!
Been making this recipe for probably 8 years. It’s amazing!! After the first year it was just expected for me to bring this dish. Everyone really enjoys it.
Could the Pecans be omitted? We have some family members with a nut allergy?
Hi Bridgette! We haven’t tried simply omitting the pecans, and the streusel topping might be a little bland without the pecans, but it should still be tasty – or just omit the streusel part entirely and simply use more mini marshmallows! Let us know what you think if you give this casserole a try 🙂
If I were to multiply your recipe to accommodate between 50 to 60 people, how I figure out how much ingredients I would need?
Hi Josiah! This casserole feeds 10-12 as written. To feed 50-60, you would therefore need to multiply everything by 5 to 6 – but I doubt you could find a pan large enough to accommodate that much. I would recommend making the recipe as written 5 or 6 individual times, in 9×13-inch pan, or three double batches if you’re able to find a deep half sheet pan (something like this might work). I hope that helps. Happy baking!
Can you make this early? The day before and then how long do you cook – do you cover?
Hi Pam! Yes, you can make this in advance. Details are in the pink tip box, above the recipe. Let us know what you think of this recipe once you have given it a try! 🙂
can I use canned sweet potatoes? how much would I use? perhaps 4 cups?
Hi Amanda! We haven’t tried that and don’t really recommend it. Check out the pink tip box (above the recipe) for some tips on making this ahead, to help save time on Turkey Day!
I’ve made this for 6 years now. BEST recipe in my opinion! Everyone I’ve ever made it for loves it too. The topping combo is the best part.
So happy to hear how much you love this recipe, thanks for the comment!
Best version of this ever and so cute on the table! Would make just for me, myself and my fork.
haha YES!! So glad you loved this recipe 🙂
Will it make a taste difference if you peel and boil the potatoes on the stovetop instead of baking them in the oven?
Nope! We just found that baking them in the oven is easier 🙂
Hi! Could I pre make the casserole and finish it off with the toppings tomorrow for Thanksgiving?
Hi Brittany! Yes, that should work fine 🙂 Enjoy!
