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!

This recipe has minimal added sugar so I’ve already done the work for you to make it healthier!

  • 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 weight loss 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.

Ingredients To Make Low Calorie Sweet Potato Casserole

Here’s the ingredients you need to make sweet potato gluten free and low calorie! You will also need a baking sheet for roasting the potatoes, a food processor or hand mixer, and an 8-inch by 8-inch casserole dish that’s oven safe.

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.

Substitutions For Sweet Potato Casserole

Here’s the substitutions I recommend you could make for this healthy recipe. Please remember when you substitute ingredients or add ingredients it will change the nutrition values from what you see in the recipe card below.

  • Sweet Potatoes – I use yams for this recipe, but any sweet potato variety will work in this recipe. If you use white sweet potatoes, the recipe may not be as sweet as yams or purple sweet potatoes.
  • Maple Syrup – Honey, stevia, monkruit could be substituted. Please note that I do not like foods overly sweet. I recommend you test the batter while making to ensure it has the right level of sweetness for you.
  • Cinnamon – Nutmeg could be substituted or pumpkin pie spice.
  • Extra Virgin Olive Oil – Avocado oil or coconut oil can be substituted.
  • Vanilla Extract – May be omitted or you could swap for almond extract.
  • Pecans – Any nut or seed may be substituted, or you can omit the nuts.
  • Coconut Flakes – You can omit this if you do not like coconut.
  • Ground Flax – If you have an aversion to flax, then I recommend you omit it.
  • Marshmallows – I use dairy free, vegan friendly marshmallows from Sprouts. You can use any marshmallow variety that works for you or omit them.

    I wouldn’t even bother telling people this was healthy – it’s stunning! Tell them after 🙂 I love roasting veggies – they become magical! I so agree, people that don’t like veggies are doing them wrong 😉 This is a must try, pinning!

    1. Megan says:

      Haha, I like it! The healthy part is an added bonus. I think that way of all the healthy food I make though. 🙂

  2. Lisa @ Lisa the Vegetarian says:

    Great recipe! I feel like so many sweet potato casseroles (especially at this time of year) are chock full of sugar and bad things. This is a nice change!

    1. Megan says:

      I feel the same. 🙂

  3. Sheena @ Paws and Pavement says:

    That looks very good! I have been making my sweet potatoes like fries but with a brown sugar glaze for Thanksgiving. I loved my sweet potatoes with marshmallows when I was younger though!

    1. Megan says:

      That sounds amazing Sheena!

  4. Rebecca @ Strength and Sunshine says:

    Magic things do happen when you roast 😉 I’ve never had a bad roasted veggie or fruit…or anything hahaha!

    1. Megan says:

      You are lucky!

  5. Morgan @ Morgan Manages Mommyhood says:

    I LOVE sweet potato casserole, and I love even more the idea of adding in maple syrup! Thanks for sharing!

    1. Megan says:

      I think I could put maple syrup on anything!

  6. Deborah @ Confessions of a Mother Runner says:

    That looks great! I love taking classic dishes and making them healthier. Thanks for joining us for MM

    1. Megan says:

      Thanks for hosting! I think we should do something fun with MM next year like other bloggers post recipes as guests on each others sites. Just a thought!

  7. Tiffany @ The Chi-Athlete says:

    OH BOY. I’m going to make this one next Thursday! We always make a very sugary apple and sweet potato casserole with candied this and that on top. I bet everyone will LOVE this! Bookmarked.:)

    1. Megan says:

      I’m sure they will love it. Let me know!

  8. Susie @ SuzLyfe says:

    YES PLEASE. Hmmmm veggies that I don’t like. I had a terrible experience with kobocha squash (seriously, disgusting. I think it must have been rotten or something) and I’ve pretty much stayed away since. I more have issues with certain fruits. I really don’t like lychee and I’m on the fence about Asian Pears. OH and I HATE cactus. GROSS.

    1. Megan says:

      For me, I can’t do beets. There’s just something too earthy about them.

  9. Tina muir says:

    YESSSSS! this is what I need!!! LOVE LOVE LOVE! Thanks for sharing for meatless monday! And TOTALLY agree about roasting vegetables being magical!

    1. Megan says:

      I’m so happy you’re happy!

  10. Michele @ Paleo Running Momma says:

    Most veggies I love roasted! Some more than others, but the magic really does happen in the oven.

    1. Megan says:

      Good thing yours doesn’t shut off anymore especially with all the veggies you eat!
