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!

Creamy White Sweet Potato Soup

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 color 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 flavor 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.

  • 1/2 cup white onion chopped
  • 2 cloves garlic mined
  • 1 tbsp butter
  • 4-5 cups chicken broth made from bouillon
  • 4 cups white sweet potatoes peeled and cubed
  • 1/2 tsp onion powder
  • 1 teaspoon parsley
  • 1/2 teaspoon basil
  • 1 cup whole milk
  • 4 tablespoons flour
  • 3 tbsp butter
  • 1 cup 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


  • 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.
  • Make 4-5 cups of chicken broth, making sure it’s enough to cover the potatoes and pour into the crockpot.
  • Peel and chop up your white sweet potatoes and place in the crockpot
  • Add the spices into the crockpot and stir in.
  • Cook in the crockpot on high for 3-4 hours, until the potatoes are slightly falling apart and the broth is cloudy.
  • When the soup is ready, cooked potatoes and slightly falling apart, you need to make a roux. (Flour/butter/milk thickener)
  • 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.
  • 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.
  • When all of the milk has been added and the mixture is smooth, add in the cheese and stir until melted.
  • 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.
  • 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.
  • 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 : )
