This Crockpot White Sweet Potato Soup Recipe came about by accident. Have you ever picked up a sweet potato in a hurry, taken it home and peeled it, only to find out it’s white? Well, I did and now you can learn from my mistake!

White Sweet Potato Soup

True story, I grabbed a sweet potato out of my pantry, started to peel it and then stared in disbelief at the colour of the potato. I was honestly completely dumbfounded as white sweet potatoes look the exact same on the outside as orange sweet potatoes do. You can’t tell unless you peel the skin. I had glanced at the stack of sweet potatoes in the store and grabbed a good looking one. I didn’t read the sign! Now to be fair, I have actually never encountered STACKS of white sweet potatoes, so I blame the store haha!  I actually had to go and research what the heck to do with a WHITE sweet potato!  What was the flavour profile? Can you substitute it for the orange? Read on to find out!

What are White Sweet Potatoes?

  • White sweet potatoes are one of three sweet potatoes : orange, purple and white. They are sadly the least healthy out of all three with less antioxidants than the other two.
  • White sweet potatoes are less sweet and are closer to Russet potatoes.
  • White sweet potatoes are a good substitution for russet potatoes but expect more sweetness. They are NOT a good substitution for orange in any way! The flavour profile is completely different. Think of a russet potato and then think if it was sweeter.

Which Crockpot should I use for this recipe?

For this recipe, we recommend a 6-8 quart oval shaped crockpot (slow cooker) such as the one pictured below. While this recipe will certainly work in other styles, this one affords the right amount of space for just the right amount of food.

  • 1/2 cup white onion chopped
  • 2 cloves of garlic mined
  • 1 tbsp butter
  • 4-5 cups of chicken broth made from bouillon
  • 4 cups of white sweet potatoes cubed
  • 1/2 tsp onion powder
  • 1 teaspoon of parsley
  • 1/2 teaspoon of basil
  • 1 cup of whole milk
  • 4 tablespoons of flour
  • 3 tbsp of butter
  • 1 cup of Tex Mex cheese and more if you want to top the soup with it
  • Sour cream- if you want to top the soup with it


  1. Saute the onions in butter in a skillet over medium heat until they are soft, then add in the garlic. Fry for another 3 minutes then add to the soup.

  2. Make 4-5 cups of chicken broth, making sure it's enough to cover the potatoes and pour into the crockpot.

  3. Peel and chop up your white sweet potatoes and place in the crockpot

  4. Add the spices into the crockpot and stir in.
  5. Cook in the crockpot on high for 3-4 hours, until the potatoes are slightly falling apart and the broth is cloudy.
  6. When the soup is ready, cooked potatoes and slightly falling apart, you need to make a roux. (Flour/butter/milk thickener)

  7. In a medium size pot over low heat, melt the butter. Stir in the flour until it's combined,it will be all clumped together, this is ok.

  8. Next, little by little, stir in the milk making sure that the milk is absorbed into the flour without making it lumpy. Eventually the mixture will be smooth.
  9. When all of the milk has been added and the mixture is smooth, add in the cheese and stir until melted.
  10. Move your potatoes to one side of the pot so there is a soup surface to mix in.Whisk in your milk/cheese sauce into the crockpot.
  11. Cook for another 30 minutes or so, stirring occasionally so there isn't a skin on the surface. If you like, you can puree the soup until smooth with an immersion blender, this is how I prefer to serve it.

  12. Serve and top with the Tex Mex cheese, extra parsley, bacon, you name it, it will work!

    Made this recipe last fall, when I had white sweet potatoes from my garden, and loved it. Somehow, I lost the recipe, but luckily I just found it again thanks to the “accident” story about the sweet potatoes. (I remembered it from the first time I read the post.) I am making it again only I will be adding a little Voodoo spice this time for an extra kick. I have printed it and it is safely in my recipe binder : )
