Healthy Sweet Potato Casserole

This healthy sweet potato casserole has all the tasty Thanksgiving flavors in one baked dish. It’s a lightened-up, sugar-free version of the classic recipe with a layer of creamy, spiced sweet potato topped with a nutty pecan crumble. It’s loaded with flavor and certainly not missing anything – you’ll love it!

Hello sweet potato, we meet again. If you’ve been following along this season, I’m sure you’ve noticed how much I love this rich, versatile vegetable. From prosciutto wrapped sweet potato to roasted sweet potatoes to a sweet potato breakfast hash, the sweet potato recipes just keep on coming!

But when it comes to the holidays, there’s no doubt that they deserve a special place amongst your Thanksgiving side dishes.

While you expect a sweet potato casserole baked with marshmallows, I figured there’s no need to add extra sugar or softness to this recipe. Instead I’ve create a delicious golden crumble made from pecans, dates, pepitas, and almond flour. The contrast between silky sweet potatoes and crispy nuts makes for the perfect texture combination.

Healthy Sweet Potato Casserole Ingredients

With just a few pantry staples and a bundle of sweet potatoes, your trip to the market will be a quick one. Here’s what you’ll need:

  • Boiled Sweet Potatoes: Instead of baking, I boil my sweet potatoes to create a similar creamy texture to my mashed sweet potatoes. This will also save you some time!
  • Milk: You can use any type of milk here, but I use cashew milk. It’s got a creamy and nutty flavor that mixes well with the sweet potatoes.
  • Butter: While I’ve used melted butter, you can also use ghee. This will add extra creaminess to the sweet potatoes.
  • Spices: Throw in a dash of cinnamon, nutmeg, salt, pepper, and vanilla extract to bring a spicy aroma to the sweet potato layer.
  • Pecan Crumble: This is a blend of chopped pecans, dates, pepitas, almond flour, and butter. It’s naturally sweetened from the dates. While the pecans and pepitas give it a savory crunch.

How To Make A Healthy Sweet Potato Casserole

This easy, one pan recipe come together with a few simple steps. Just follow along below and you’ll have a winning Thanksgiving side dish in no time.

  1. Boil the sweet potatoes. Bring a large pot of water to boil, peel and dice the sweet potatoes, and let them cook for 20-30 minutes.
  2. Mash the sweet potatoes. Drain them with a colander and mash the sweet potatoes in a large bowl with a hand masher or electric beater.
  3. Add the butter and milk into the bowl and mix until it’s creamy. Then add the seasonings and blend again.
  4. Make the crumble topping. First, roughly chop the pecans, dates, and pepitas and toss them in a large bowl. Then add the almond flour and butter and mix with your hands until everything is combined.
  5. Spread the sweet potato in a flat layer into a baking dish.
  6. Sprinkle the pecan crumble on top as thin, even layer.
  7. Bake for 25-30 minutes, until the top becomes a nice golden brown.
  8. Let it cool once you take it out of the oven, then serve!

Prepare This Casserole Ahead Of Time

Looking to meal prep this casserole ahead of time? No problem. To do this, just make sure to keep your mashed sweet potatoes and pecan crumble separate and tightly covered in the fridge.

On the next day, take the the mixtures out of the fridge and let the sweet potatoes thaw for about 30 minutes. Then, spread the sweet potato into an even layer in the baking dish and sprinkle the pecan crumble on top. Pop the dish into the oven and bake for about 30 minutes or until the top is golden and crisp.

  • Bring a large pot of water to boil on high heat.
  • Peel the sweet potatoes with a hand peeler.
  • Dice the potatoes into chunks and place them into the pot. Cook the potatoes for 20-30 minutes, or until the potatoes are fork tender.
  • Drain the potatoes over a colander, and place the potatoes in a large mixing bowl and mash them with a hand masher or electric beater.

  • Bake for 25-30 minutes, or until the top is golden brown.

Lisa's Tips

  • To create a more creamier sweet potato layer, use a food processor, hand mixer, or stand mixer to blend.
  • To make it dairy-free , you can swap butter for ghee as well as use any type of nut milk.

  1. This was a hit during our 2020 thanksgiving dinner. Even with my husband that is not a big fan of sweet potatoes. I also follow an AIP diet and this recipe was super easy to modify!5 stars

  2. I wanted a few healthier versions to choose from for Thanksgiving dinner my husband and I made this together. It was fun to cook something as a team and it turned out absolutely delicious. It was a little daunting dicing up the sticky dates so when I make this again I will probably buy them already packaged. Lol
    But the point is I will definitely be making it again it was very tasty and such a healthier version of a famous holiday dish. Lisa never disappoints5 stars

  3. This was hands down my favorite Thanksgiving dish! It is so good! Thanks for the fantastic recipe, Lisa!5 stars

  4. YUM! So versatile and delicious, as are all of your recipes. I had walnuts, so I used those. This was a hit with the family, and I’ll surely be making it again. Thank you!5 stars

  5. Can I make this with a white sweet potato or does it have to be the yellow one ?

  6. Hi, thank you for this recipe. I wonder if I can use brown sugar or raisins in place of the dates, and oat flour OR all purpose flour for the almond flour? Also, sunflower seeds for the pepitas? I’m not on a strict diet, or any diet for that matter, so I think having nuts and seeds instead of the usual sweet potato/marshmallow recipe is already a great healthy change. I’m sorry to butcher this great sounding recipe but I don’t have these ingredients and prefer to use what I already have. Thank you so much again.

  7. Hi Lisa, Can this be made ahead of time? I have some sweet potatoes now, and would love to freeze this casserole for Thanksgiving. Would you recommend that for this recipe? Thanks!

  8. Hi Lisa! I am looking forward to trying this recipe for Thanksgiving this year. My husband is allergic to nuts — do you have a suggestion for substituting the pecans?

  16. I made this dish for a Rio de Janeiro Thanksgiving, using organic sweet potatoes, a mixed nut milk, ghee instead of butter, and finally walnuts (because I was also making a pecan pie).
