Ingredients for sweet potato casserole
- Mashed sweet potatoes – feel free to roast your own whole potatoes and mash them BUT you can easily use canned mashed sweet potatoes (like canned pumpkin but sweet potato) or simply buy a can of cooked yams and mash them.
- Coconut milk – I used refrigerated coconut milk to help smooth out the mashed sweet potatoes.
- Unsalted butter – Just a touch for richness and buttery flavor.
- Vanilla bean paste – I love using vanilla paste in this recipe as it gives a big punch of vanilla flavor with pretty black flecks.
- Brown sugar – The brown sugar brings in a touch of sweetness with a subtle molasses flavor.
- Pumpkin pie spice – I love using pie spice because it’s a delicious combination of spices like cinnamon, cloves, and ginger.
- Kosher salt – Gotta add a sprinkle to highlight the flavors.
- Vanilla sugar – If you can’t find vanilla sugar you can use course granulated sugar but the vanilla sugar will bring more of a vanilla punch.
- Granola – Use whatever granola you have on hand that you think would work well in this recipe. I used a basic honey nut granola that had no dried fruit or chocolate and was simply just oats and nuts.
- Mini marshmallows – I’m using your basic everyday mini marshmallow. Use whatever brand you love the most.
How to prepare your sweet potatoes
I found canned mashed sweet potatoes, so I used that for this recipe. It made putting it together so easy.
However, if you cannot find canned mashed sweet potatoes, try mashing canned cooked yams, roasted whole, or boiled.
To boil, simply skin the potatoes, cut them into 1-inch cubes, add them to a large pot filled with water, set over high heat, and boil until soft. Drain and mash.
What granola to use
For this recipe, I used a basic honey nut granola made from oats and nuts. I tend to shy away from granola with dried fruits in it for this topping, but in a pinch, it could work.
I also like granola with flavorings such as cinnamon, cloves, or pumpkin pie spice.
They tend to go well with sweet potatoes and vanilla flavors.
Make ahead
If you’re looking to prep this dish the night before, you’re in luck because it’s the perfect dish for prepping ahead!
I like to prep the mashed sweet potato part first, cover it, put it in the fridge, let it come to room temperature 30 minutes before baking, then freshly top it with granola and marshmallows and bake!
It’s just that simple!
My main reason for waiting to put on the topping is that the granola can get soft if it sits too long before being baked.
Storage and leftovers
Store any leftovers in an air-tight container in the refrigerator for up to 3 days.

I’ve always loved sweet potatoes but, like you, don’t want them full of sugar. They just don’t need it. Their natural sweetness is just perfect to me and some vanilla only enhances it. Great recipe! Adding to my list for Thanksgiving dinner.
This would be perfect for Thanksgiving
I am so looking forward to Thanksgiving now! Love it
The only way I ate sweet potatoes until recently was from a can and with lots of brown sugar, cinnamon and butter. Haha. Classy. Now I also eat them in fry form. 😀
But this sounds good! I could definitely do this.
Are those the Home Depot tiles, by the way? They look great!
This sweet potato casserole could easily double as dessert! 🙂 I just love your little additions to this classic side dish. And those mini marshmallows?? Essential. 😉
Yes, yes, and more YES! I felt the same way as a kid, but LOVE them now. I still don’t like them super sweet, but this look and sound like the perfect compromise to the typical ones on a Thanksgiving table. I think this may be one of my contributions to the family potluck this year!
Oh man, this looks absolutely perfect. I’ve never been a huge sweet potato fan but this recipe just changed my mind. Plus it’s so darn pretty.
Yummy…I love loaded sweet potato casserole and have never thought of adding granola before. I can’t wait to try it!
Mmm, I love that you can probably get away with eating this for any meal, let alone dessert. Those toasted marshmallows on top look so perfect!
