Healthy Sweet Potato Casserole
Ever since I was a little girl, my most favorite Thanksgiving recipe has been Sweet Potato Casserole.
I grew up eating a sweet potato casserole that was made with canned sweet potatoes in heavy syrup,combined with more sugar, eggs, and milk. AND then topped with butter, more sugar, nuts, and flour. I am not going to lie. It was incredible.
But as our family grew, many food issues arose. We have dairy allergies, egg allergies, and gluten sensitivities.
Our classic recipe needed to be revamped.
I took it upon myself to recreate my family’s Sweet Potato Casserole and make it healthy and allergy-free while still keeping the family happy. And if you have ever messed with a classic recipe passed down for generations, that can be quite the task.
After multiple tries, SUCCESS! I have created a Healthy Sweet Potato Casserole that is dairy-free, egg-free, gluten-free, but MOST importantly absolutely delicious. In fact, my entire extended family prefers this Vegan Sweet Potato Casserole to the traditional–hands down!
Healthy Sweet Potato Casserole Swaps
- Sweet Potatoes: Instead of canned sweet potatoes in a thick syrup, this Sweet Potato Casserole starts with baked sweet potatoes. You can bake them in the oven or make Instant Pot Baked Sweet Potatoes. Pro Tip: Roast the potatoes while you are baking something else, like dinner the night before you plan to make your sweet potato casserole.
- Maple Syrup: Rich and earthy, maple syrup pairs PERFECTLY with sweet potatoes and adds just the right amount of sweetness to this casserole.
- Apple Juice Concentrate: Not apple juice, but instead apple juice concentrate. It is a perfect ingredient to replicate the sweetness in traditional sweet potato casseroles without the refined sugars.
- Oats: Instead of using both oats and flour to create a sweet potato topping, process certified gluten free oats in the food processor for a crumble that resembles the classic, while being gluten free.
- Coconut Oil: Coconut oil makes a great dairy free option to replace butter and gives the crumble on this casserole a rich, nutty finish. Feel free to use vegan butter or canola oil in place of coconut oil if desired.
- Nuts: Walnuts or Pecans are a wonderful source of crunch and healthy fats, but feel free to omit the nuts and use additional oats to keep this Sweet Potato Casserole nut free.
How to Make Sweet Potato Casserole
Step One: Prepare Sweet Potato Casserole Filling
- Roast fresh sweet potatoes at 400 degrees for about 1 hour, or until fork tender. Alternatively, use my recipe for Instant Pot Baked Sweet Potatoes.
- Remove the skins from the sweet potatoes and place the flesh of the potatoes into the food processor or blender.
- Add in apple juice concentrate, maple syrup, cinnamon, nutmeg, and vanilla extract while pureeing to finish off the base of the casserole.
- Place sweet potato puree into a greased 2 quart baking dish.
Step Two: Prepare Gluten Free Sweet Potato Casserole Topping
- Wipe out the blender or food processor (no need to wash, just rinse or wipe out.
- Place the oats, cinnamon, nutmeg, coconut oil, nuts, and maple syrup into the food processor and pulse until the oats are broken down and the crumble comes together.
- Evenly sprinkle the crumble over the sweet potato puree.
Step Three: Bake Casserole
- Bake at 350 degrees for 45 minutes or until heated through and the topping is golden brown.

My kiddos are allergic to nuts. Do you think it will negatively impact the crumble if I leave out the nuts? Do I need to replace the nuts with another ingredient?
Hi Betsy! I would use 1/4 cup more oats and leave out the nuts–it will be perfect!
This looks great! My husband is a picky eater too, and I look for recipes without certain ingredients, otherwise I have to make a separate casserole for him (no onions or mushrooms, for example). We both love sweet potatoes and will eat them baked, but sometimes you just have to change it up. Thank you for your recipe!
I am so glad to hear you both can enjoy this casserole Millican.
This is far and away the best sweet potato casserole I’ve ever had! It is just sweet enough without being cloying. And you are right about the apple juice concentrate being essential; the flavor compliments the sweet potatoes perfectly.
And no one would be able to tell that this is gluten free and vegan unless I told them. This may become my new go-to potluck recipe :).
The only thing I’ll do differently next time is use a shallower casserole dish; I used a 2-quart dish as recommended, but it was too deep and not wide enough, quite, and so the outcome was a little watery. It didn’t hurt the flavor, though!
I am so so glad to hear you love this sweet potato casserole as much as we do! And I just served it to my family yesterday—and they had no clue it was vegan either.
Do you think it would be ok not To mash the potatoes?
Hi Clarrisa, I think you need to at least semi mash them so that they can absorb the spices, maple syrup, and apple cider concentrate. You can leave them chunky for sure, but I am not sure if they would turn out without mashing. I understand some recipes call for just sliced sweet potatoes, but in order to get the sweet potatoes tender you would need to cook so long the sugary syrup would burn as well. Sorry!

Miss Kristin,
In your reply, here, you mentioned “apple ‘Cider’ concentrate”. Was that a typo? The ‘cider’ part sounds a bit more inviting, to me. But being diabetic, ‘concentrates’ are not friendly. If needed, can I omit the concentrate and increase the maple syrup. For some reason, maple syrup doesn’t seem to affect me, like juices do.
Hi Thomas! Yes, this recipe does call for concentrate. HOWEVER, by all means, omit the concentrate and increase the maple syrup. I have done this in the past with great success. I would suggest using 1/2 cup maple syrup. I hope you enjoy!
What’s a good sub oil for coconut?
Hi Janey! You can use canola oil or melted butter in place of coconut oil 🙂 Enjoy!
This looks delicious! I love that it is gluten-free!
Thanks Carolyn, it is a great option to serve to gluten-free guests at the Holidays.
Sweet Potato Casserole is one of my favorites! Can’t wait to try your healthier version!
I am willing to be you will LOVE it 😉
Quick question – when you say “coconut juice, melted”, do you mean coconut oil? I would assume so, but wanted to be sure. 🙂 And I’m so excited to try this!
Oh goodness yes!! I need to change that ASAP! And you can watch me prep this here if you are interested: https://www.facebook.com/amindfullmom/videos/1795576154048856/

Sweet potato casserole is one of my favorite parts of Thanksgiving! This looks delicious!
Mine too Marye–and this one is AMAZING!!!
LOVE that this is naturally sweetened!
All the more reason to have 2 or 6 servings 🙂
Ooh I love this idea! Nice spin on a classic!

This looks so yummy!

You bet! I love your parties!
Nice spin on a Thanksgiving classic. Thanks for the share!
Thanks Melissa
Something like this is totally happening on Thursday except with butternut squash! 🙂
OOH–Sounds AMAZING!!!!
I love this! I think sweet potatoes are sweet and delicious enough that they don’t need all the sweetening up. This will be perfect.
Totally agree Lindsay. Sometimes I just mash a banana with them to make this casserole (even less sweet) But this version is a close to my family’s as you can get.
We are having a “friendsgiving” carry-in at work on Wednesday this will be perfect for that!
I love Friendsgivings!! More reasons to celebrate and eat!! Let me know how everyone likes it!!
my mom puts marshmallows on top of her sweet potatoes!
I just found kosher and all natural marshmallows at publix–my kids were so excited to have them in hot cocoa. I need to pop a few on their sweet potatoes next time too!
