Is There a Difference Between Sweet Potatoes and Yams?
Yes! While the United States tends to use the terms sweet potatoes and yams interchangeably, there is actually a difference.
Sweet potatoes are the root veggie we always see in the produce department. Unless you shop at ethnic markets, there’s a strong chance you’ve never even encountered an actual yam. Yams are not orange inside, but white.
Yams are starchier than sweet potatoes and have a rough, bark-like skin. American products labeled “yams” are almost always sweet potatoes.
So all those orange beauties, as well as the purple ones are really sweet potatoes and not yams.
For this recipe, you want the vegetable that is orange, not white, even if it’s labeled as “canned yams.”
What If I Want to Use Fresh Sweet Potatoes Instead of Canned?
It’s perfectly okay to sub fresh cooked sweet potatoes for the canned version. You’ll need about 4 to 5 sweet potatoes for this recipe.
Follow these easy steps to use fresh sweet potatoes:
- Peel and cube 4 to 5 medium sweet potatoes and add to a pot of cold water on the stove, covered with water completely.
- Bring the pot to a boil, then lower the heat to a simmer. Allow the sweet potatoes to cook for about 15 to 20 minutes until they are very tender to pierce with a fork.
- Drain the sweet potatoes and continue the recipe as stated.
Can I Make This Recipe Ahead of Time?
You can make the main part of this sweet potato casserole ahead of time and store it covered in your refrigerator until you’re ready to bake it. You can even make it 2 days in advance!
Wait to add the marshmallows until the end of baking. Marshmallows on a refrigerated casserole could break down and get gooey in a bad way.
If you like to prepare and plan ahead, you can even freeze this casserole without the marshmallows. Just add them at the end of baking, as the recipe describes.
Can I Double This Recipe?
Yes! If you have people coming over for a large Thanksgiving dinner, you can double this recipe by using a 2QT dish and doubling all ingredients.
The casserole will still cook at 350 degrees but will take longer to cook, about 45 minutes, before adding the marshmallows.
How Do I Store the Leftovers of My Sweet Potato Casserole?
If everyone doesn’t gobble every yummy bite up right away, you can save what’s left for later.
This sweet potato casserole will stay good in the fridge for 3-4 days tops. Just cover it with plastic wrap, or keep it in an airtight container.
How to Reheat Sweet Potato Casserole
- Preheat your oven to 350 degrees F.
- Cook the leftover casserole for 20 to 25 minutes, until thoroughly warmed.
You can also heat slices of the sweet potato casserole back up in the air fryer. Just preheat it to 320 degrees and cook for about 4 to 5 minutes until warm.
Do not reheat this recipe back up in the microwave as the marshmallows can explode.
Can You Freeze This Sweet Potato Casserole?
Yes! You can freeze the sweet potato casserole before and after cooking.
To Freeze Before Cooking
Prepare the casserole up to spreading the mashed sweet potato mixture in the baking pan, then freeze. Once ready to make, thaw in the fridge overnight, bake, then add the marshmallows and pecans as directed.
To Freeze After Cooking
Remove the marshmallows from the cooked sweet potato casserole (freeze before cooking if freezing the entire casserole whole).
Freeze leftovers in an airtight container for up to 2-3 months. Thaw overnight before cooking.
I recommend taking the marshmallows off and using new ones when you reheat after freezing. They can become gooey and just not appealing.

Used oven not air fryer?
Hi Norma, yes this recipe is made in the oven.
Just found out I’m allergic to gluten, wheat, eggs and dairy so can I use applesauce instead of eggs or can I use the JustEggs made from mung beans in this recipe?
I have never made the recipe with either, but I would choose the egg substitute over the applesauce just to keep the flavors intact. If you do try it that way, let me know how it turns out!
Too dry and not sweet enough 😵😵😵😵 how could I make it not so dry? I followed the recipe to a T.
Hi Jennifer, I’ve never had mine turn out dry before, but make sure the sweet potato mixture is fully mashed/pureed before adding it into the casserole dish. That way all of the wet and dry ingredients are fully mixed.
How long do I cook this if I triple the recipe?
Hi Helen, I have not tripled the recipe before, but I would lower the temperature about 25 degrees and let it cook for longer as it will be thicker. If cooking it in 3 separate dishes in the same oven, you can keep the time and temperature the same.
Definitely double the recipe! It’s so good you’re going to want left overs!
DONT BROIL THE MARSHMALLOWS! Mine caught on fire and had flames all over my oven, the rack was down low and only in for 2 min.
Alternative up the temp a few degrees to brown the marshmallows.
Hi Chelsea, I’ve never had any issues broiling the casserole with the marshmallows on it though it doesn’t take long to brown them.
Oh my, what a lovely recipe!
I’m so glad I picked this recipe. Others recipes seemed overly complicated. The instructions use the exact size of the can – 40 oz, and also the only one that says to Drain the liquid. Thank you!!
The sweetness was spot on. Plenty sweet, but not overkill or bland.
Some recipes called for regular sugar, but I really liked the flavor the brown sugar adds.
We really liked the texture, which was slightly firm, but not dry. And not runny.
The toasted marshmallows were so good, but we had to take them off broil bc they were cooking too fast & not browning. (Could be our oven- first time we’ve used broil)
We just turned off the oven & left them in for a minute or so & they finished perfectly.
Definitely added this recipe to our permanent collection. Looking forward to making it again!
Can this be made in a slow cooker?
I have not tried it in a slow cooker, but you won’t be able to roast the marshmallows unless you use a torch.
Can you bake the sweet potato casserole a day ahead or hours ahead of the meal?
Yes! It will need to be reheated in the microwave or oven (preferred) prior to eating though. If you can, prepare the casserole and then let it sit until you’re ready to cook it. Just wait to add the marshmallows until your food is about to be served.
