My Sweet Potato Casserole lightened up still has all the buttery, brown sugar flavor of a traditional casserole with half the calories!

Sweet Potato Casserole is my favorite Thanksgiving side dish. It wins by a mile. I will happily pile up my plate with gravy-free turkey, steamed green beans and a whole-wheat roll as long as I have my sweet potato casserole.
Who doesn’t love eating dessert WITH dinner before getting to the real dessert…pie?!

In high school and college, my best friend, Julia, regularly joined my family for Thanksgiving. She was in charge of bringing her sweet potato casserole…It was crazy good. Sweet, buttery filling topped with a toothachingly sweet brown sugar pecan topping. The good stuff.

Last year when I was planning on hosting Thanksgiving for the first time (You can read about my adventures with that here, here, and here!), I requested the recipe from Julia, and I almost fell out of my chair. There was more butter and sugar in the casserole than I even had in my cupboard!
So, with the help of my husband, I lightened it up.

This isn’t a healthy sweet potato casserole; so don’t even go there. It’s just not as indulgent as a traditional one!
Most of the calorie savings are from drastically reducing the butter and sugar in the filling. To me the topping is sacrosanct and shouldn’t be messed with, but you could always reduce the sugar and add more flour and oats as filler. But why? It’s Thanksgiving, the day of indulgence!

This casserole has brown sugar in every bite but it isn't cloyingly sweet. Toasting the pecans is calorie free flavor boost! It has the added benefit of keeping them a touch crunchier even after refrigerating. Since I reduced the amount of butter and sugar in the filling, the actual sweet potato flavor is more pronounced and you are reminded why sweet potatoes are so awesome even by themselves!
My husband likes sliced sweet potatoes in this casserole but I got distracted (shock!) and cooked the thin slivers too long and they didn’t hold together in a beautiful layered form like last Thanksgiving. Immersion blender to the rescue!

Fortunately they are just as good when the filling is mashed. It just doesn’t look as classy.

Kitchen Tip: Boiling the sweet potatoes will preserve that beautiful, bright orange color. This will provide a gorgeous color contrast in the casserole but will also keep your sweet potato pies, cakes and cupcakes orange too!

Sweet Potato Casserole Lightened Up
Ingredients
For the Filling:
- 3 pounds uncooked sweet potatoes (sliced ⅛ inch thick or cubed)
- 1 cup dark brown sugar (unpacked)
- 2 eggs (lightly beaten)
- 1 ½ teaspoons vanilla
- ½ cup low fat milk
- ½ cup melted butter

- ½ cup dark brown sugar (packed)

- In a large bowl combine brown sugar, eggs, vanilla, milk, butter and salt. Whisk to combine.
- Boil sweet potatoes in cold water, just covering, until fork tender. Drain well.

- Bake 30-40 minutes until bubbling.

Erlene says
This is going to sound weird, but I'm not a fan of mash sweet potatoes, but I love eating it in chunks. Do you think this would work if I didn't puree the potatoes and just left them in chunks?
Lindsey says
We all have our preferences! Absolutely you can leave them in chunks and it will taste just as good. I like to make this casserole with sliced sweet potatoes, which I planned to do here but I forgot about them on the stove and they cooked too long to stay whole, so I had no choice but to mash them!
marcie says
I make a casserole similar to this and have lightened it up significantly as well...still not healthy...but lighter. 🙂 It's one of my favorite side dishes too, and I like the idea of using sliced sweet potatoes, too!
Lindsey says
Yours is probably way healthier than this one..and that is why you are so thin! 🙂 The sliced sweet potatoes were so pretty...if only I hadn't been distracted!
David @ Spiced says
Haha! I think we were separated at birth...as soon as I saw "gravy-free turkey," I knew we must be related somehow. I can't stand gravy on my turkey! Now to be fair, we might be like distant cousins or something because I just don't love sweet potato casserole. Sweet potato pie? Now that's a whole different story...but I have some weird issue with sweet and savory flavors combined in a savory style dish. With all of that said, your sweet potato casserole looks amazing...and I love the toasted pecans. Nice work!
Lindsey says
My money is on distant cousins. But let me make sweet potato casserole for you and we'll see how you feel then, mmkay? Maybe it will help if you think about sweet potato casserole as a crustless, deep-dish pie with a crumble topping?
Julianne @ Beyond Frosting says
Sweet Potato Casserole is one of my favorite! I've got one coming up tomorrow!
Lindsey says
Mmmm can't wait to see yours!
Kristi @ Inspiration Kitchen says
I am *so* glad you're featuring some lightened up recipes to counteract my eatin' pants posts! LOL. I personally love sweet potatoes, and I'm with you - the topping should not be messed with! Having dessert with dinner sounds like a perfectly acceptable and necessary idea to me! I am loving it! Pinned!
Lindsey says
lol! I'm trying to make sure that my eaten' pants aren't the only pants that fit in January! Thanks for the pin
Josephine says
Thanks for this healthier version. I will pass it along to my healthy cooking sister in law who has been assigned sweet potatoes.
Lindsey says
Welcome! There is still more lightening up that can be done but I didn't have the heart to do it 🙂
Gayle @ Pumpkin 'N Spice says
I've only recently started to like sweet potatoes, so I'm discovering my love how I like them prepared. This casserole looks delicious, Lindsey! I like how it's on the lighter side, but still full of flavor. And that topping sounds amazing! Delish!
Lindsey says
Oh I am a HUGE fan of sweet potatoes both for the sweet and savory.
Manali @ CookWithManali says
wow this looks delicious. I have never had one before 🙂 Thanks for this lighter version Lindsey, I will give it a try! Pinning.
Lindsey says
Thanks, Manali! Never had a sweet potato casserole?! oh dear. Try it! Thanks for the pin!
Kathleen @ Yummy Crumble says
The color is amazing! Sweet potato casserole is my most favorite dish at Thanksgiving but I always feel guilty and not eat dessert. Now I can do both! Thanks for this 🙂
Lindsey says
Oh wow, you have waaaaay more will power than I! I eat sweet potato casserole AND dessert. I figure it's one day a year...

Kelly - Life Made Sweeter says
I would happily forego the turkey just to have more room for side dishes and dessert 🙂 Especially this sweet potato casserole, it looks incredible and I love that you lightened it up too! I would totally be piling a big serving or two of this on my plate 🙂 Pinned!
Lindsey says
LOL that makes 2 of us, Kelly! I only eat the turkey because I have to have something to put my cranberry chutney on!
