  • 2 lb purple sweet potatoes peeled and diced into 1" cubes
  • 1 lb frozen cauliflower thawed
  • 1 medium yellow onion
  • 4 cloves garlic peeled and pressed
  • 6-8 cups low-sodium chicken broth
  • 3-4 cups filtered water
  • 2 large carrots peeled and chopped into small pieces


  • Peel the carrots and potatoes. Then chop each into small pieces about 1" cube and set aside
  • Place a large pot with a lid on the medium heat and add the onion. Let saute for 1 to 2 minutes.
  • Add the garlic, carrots, water, cover and cook until soft about 3 minutes.
  • Add the potatoes and cauliflower then cover with 7 cups of broth. Bring to a boil and lower heat then continue to cook until veggies are soft and tender (about 10 to 15 minutes).
  • Once the veggies are cooked soft take an immersion hand blender and blend the mixture until the veggies are all pureed. If too thick you can add more broth to thin out the soup. Continue to blend until the soup is at a desired consistency.


If you don't have a hand immersion blender you can use a regular blender with a soup setting.
