This crockpot butternut squash soup is a warm and creamy soup that’s cooked up in the slow cooker. It’s easy and requires very little effort. Although it’s creamy, there’s no cream added at all! The recipe is completely vegan and is full of sweet butternut squash and apple flavors.

There are only three simple steps to making this soup. You can throw it all in your slow cooker before you leave for work and you will have a delicious soup waiting for you when you get home with not much left to do other than purée the ingredients.

If you’re looking for a healthy, dairy-free soup, this is the dish for you. Serve with some warm crusty bread or a simple side salad. 

“This butternut squash soup was delicious and makes a lot! I filled a 7-quart slow cooker about 2/3 full and cooked it on high for 4 hours. You could cut the prep time if you use pre-peeled and cubed squash. I got 3 quarts of soup using a 6-pound squash.” —Diana Rattray

Use Caution When Blending Hot Ingredients

Steam expands quickly in a blender, and can cause ingredients to splatter everywhere or cause burns. To prevent this, fill the blender only one-third of the way up, vent the top, and cover with a folded kitchen towel while blending.


  • If the soup is too thick, you can add in more vegetable broth, some apple cider, or more coconut milk.
  • Tie the herbs together with a piece of kitchen twine so they can be removed easily when the soup is done.


  • If you don’t need this soup to be vegan, you can add butter, substitute chicken broth for vegetable broth and cream for the coconut milk. A dollop of sour cream also tastes delicious in place of dairy-free yogurt.
  • If you love the apple flavor, you can add in an additional 1/2 cup apple cider.
  • Use whatever types of apples you like. Using one tart and one sweet works well. Go ahead and leave the skins on. They provide nutrients and a nice color. 
  • Instead of thyme, add a few sprigs of sage leaves to the soup.

How to Store Butternut Squash Soup

  • Refrigerate leftover butternut squash soup in a covered container and consume within 3 to 4 days.
  • This soup freezes beautifully. Transfer the cooled soup to single-serving or family-size freezer containers or freezer bags—label with the name and date and freeze for up to 1 month. Defrost the soup in the refrigerator for several hours or overnight.
  • Reheat butternut squash soup in a saucepan on the stovetop over medium-low heat until hot.
