This Healthy Sweet Potato Casserole is a holiday favorite in my house! In fact, several years ago my Mom roasted sweet potatoes and blended them in a food processor with a little maple syrup to make mashed sweet potatoes. She raved to me how good they were.
I reminded her of the healthy sweet potato casserole I made over Thanksgiving and how it was the same recipe only served in a casserole dish.
I think we often forget how simple foods like sweet potatoes can be easy, delicious and healthy! This recipe is a good example of that and how you can tweak a traditional holiday recipe to make it better for you and your family.
What Makes This Sweet Potato Casserole Healthy
Most sweet potato casseroles are loaded with ADDED sugar. Now there is a difference between the natural sugar from sweet potatoes and sugar that's been added to a recipe. Natural sugar from sweet potatoes is high in fiber and has nutrients the body loves!
Added sugar is what you want to be aware of with recipes on Pinterest and the internet. This is what causes inflammation, weight gain, insulin resistance and other health problems. This recipe has minimal added sugar so I've already done the work for you!
- Low Sugar - Only one tablespoon of added sugar from maple syrup is put into this sweet potato casserole. The remaining comes from natural sources as well as cinnamon and vanilla extract.
- High Fiber - One of the reasons potatoes are so good for a healthy diet is they're high in fiber (a really important weight loss nutrient I talk about in this free class) and it's high on the satiety index.
- Low Saturated Fat - The majority of the fat in this recipe is healthy - monounsaturated and polyunsaturated. Only 3 grams come from saturated, or less optimal fat.
- Gluten Free - All ingredients are naturally gluten free.
- Low Calorie - Because this recipe uses very little added sugar, the calories are much lower than other sweet potato casserole recipes. You can make the calories even lower with a sugar substitute like stevia or monkfruit.
- Dairy Free / Vegan - This recipe is dairy free.
- Paleo - This recipe is Paleo friendly.

How To Make Sweet Potato Casserole Gluten Free
Here are the steps to making this sweet potato casserole. Don't worry it's easy and you can make it ahead of time too, which I'll share with you below.
To start, clean and peel the sweet potatoes. Slice in half lengthwise then place on a prepared baking dish. Spray lightly with cooking spray and sprinkle with cinnamon before placing in the oven to roast. As a side note, you can roast potatoes in an air fryer too.
Once the potatoes are roasted, place in a food processor or in a mixing bowl and mix until smooth. Add the maple syrup, olive oil, salt and vanilla extract and blend until smooth. Transfer the mixture into a casserole dish. Top with the optional toppings and bake about 10-minutes in the oven to set the toppings.
Can You Make Sweet Potato Casserole Ahead Of Time
If you're wondering if you can make sweet potato casserole in advance, the answer is yes. In fact, this is what I do during the holidays. I like to make as much as possible ahead of time so I can actually enjoy the holidays.
If you want to make sweet potato casserole ahead of time, I recommend you complete all the steps up to the point of topping with the optional ingredients baking in the oven (step 6 in the instructions below) with the toppings. Cover the casserole dish with foil and place in the refrigerator. You can do this up to 3 days ahead of time.
To heat, remove the sweet potato casserole from the refrigerator and bring to room temperature. Add the optional toppings and warm in the oven at 325 F 30-minutes.
