The BEST Healthy Sweet Potato Casserole
This casserole was born out of an obsession, er curiosity, with small crockpots. You see, I had been eyeing them for quite a while. Then, one year, we celebrated Thanksgiving at my sister-in-law’s home, and she had one!
Obviously, I had to try it out and quickly whipped up a small batch sweet potato casserole recipe. Well, obviously it was a huge hit, and it couldn’t have been easier to make! Plus, it left the oven free to finish up the turkey.
I had no choice but to buy my own small crockpot immediately! Now, I use it for everything from shredded chicken to small roasts, and this side dish is now a staple for the holidays. Not only is it super easy to make, but it’s also way lower in sugar than the classic dish so you can enjoy all the goodness while knowing that you’re also fueling your body with better-for-you ingredients!

For the Casserole
- Sweet Potatoes – The star of the show! You’ll need four cups, or 690 grams of sweet potatoes. Make sure to peel and chop them before you begin.
- Sweetener – We use golden monk fruit sweetener to keep this recipe low in sugar, but brown sugar or coconut sugar will also work.
- Vanilla Extract – Adds delicious vanilla flavor and enhances the sweetness of the filling.
For the Topping
- Chopped Pecans – Add a satisfying crunch. Walnuts or almonds will also work.
- Sweetener – Again, we use golden monk fruit sweetener, but brown sugar or coconut sugar will work.
- All-Purpose Flour – This adds structure to the topping, helping creating a crumbly consistency. If you need to keep your casserole gluten-free, use a 1:1 all-purpose gluten-free flour instead.
- Unsalted Butter – Adds richness and helps create a crisp topping. Feel free to use your favorite plant-based butter or coconut oil to keep this recipe dairy-free.
