Can you believe that I grew up not liking sweet potatoes, much less a casserole made out of them. I often mourn the years I wasted not loving them. Okay, I may be exaggerating. Ha! 

I was inspired to make this Skinny Sweet Potato Casserole on a very special Thanksgiving a few years ago.

My family and I traveled 3 hours to spend the holiday with my sister and brother-in-law, aunt, cousins, and friends. It was a blessed time full of treasured memories…and amazing food.

Always the food, right? πŸ™‚

You see I had been wondering for months if I too needed a tiny crock-pot. I always managed to talk myself out of it though, reasoning that I already had so many kitchen appliances. Surely it would not be used often.

Wrong. Wrong. Wrong.

One taste of that delicious and healthy sweet potato crock pot recipe prepared by my sweet aunt and I knew I NEEDED this tiny cooking device too.

After returning home and using all the Kohl’s coupons I had (thanks Kohl’s, you rock!), I inexpensively purchased my favorite new kitchen appliance.

And guess what? I use it almost weekly! Obviously, I don’t make this casserole weekly. However, I do cook a lot of chicken breasts and small roasts to then shred for salads or to use in main dishes.

Shortly after my purchase, I started “healthifying” the sweet potato recipe my aunt shared with me right away in my beloved little slow cooker and haven’t looked back since.

The skinny aspect of this recipe comes in the fact that it contains very little sugar and all whole food ingredients. Your guests will never guess this dish has been “lightened” up though.

It is every bit as indulgent as the original version even though it is dairy free, gluten free, and vegan.

This healthy version will surely be on our table this Thanksgiving!

  • small crock pot



  • 4 cups sweet potatoes, peeled & chopped into 1" pieces (3 medium-large sweet potatoes)
  • 1/2 cup water
  • 1 tsp vanilla extract
  • 1/4 cup coconut sugar



  • Lightly grease your 1.5qt crock-pot. Place peeled and chopped sweet potatoes along with the water in crock-pot and cover. Cook on high 3 hours.
  • Then mash the potatoes well or use an immersion blender to make it smooth. Mix in vanilla and sugar until combined.
  • In a separate bowl, mix together topping. Sprinkle over sweet potatoes and replace the lid. Cook on high another 2 hours.
  • Serve warm from the crock-pot or remove from base, cool, and put in fridge. Enjoy!


*To save you time preparing your holiday meal, cook the sweet potato portion, allow it to cool, remove from base, and store in the fridge a few days ahead of time. Then set the ceramic dish back into the base of the crock-pot, add pecan topping, and re-heat on HIGH for 2-3 hours or until pecans are candied and "set".

  5. What a deliciously healthy recipe! I love how you have made this classic better for you, Sammi. Thank you so much for sharing it with us at Hearth and Soul. And what a great crock pot too!

  6. The best part about this recipe is the crockpot part. This would be a hit as a dessert for a party, and bonus points for not slaving away in the oven to serve it! Thanks so much for sharing this with us on #shinebloghop! Always a pleasure to have you join us, Sammi!

    • Well thank you for hosting such a fun party each week, Maria! Yes, no slaving away in the kitchen for this recipe which is so nice on busy holidays. I appreciate your kind words. Happy Fall!

  8. Hi Sammi, Here’s the URL for the Slow Cooker Green Bean Casserole I use at Thanksgiving. I also like it because it doesn’t contain soy sauce like the traditional green bean casserole. Hope you enjoy it!

  9. Hi Sammi, What a wonderful recipe & I really like that you’ve made it in the slow cooker! I make a Green Bean Casserole in the slow cooker on Thanksgiving to free up the oven for other food. This is another great way to free up the oven! Thanks for sharing this recipe & I look forward to trying it! Blessings, Janet
