You need just five ingredients to create this flavorful crock pot cream of asparagus soup and it’s one of my favorite dishes to make during a busy week! All you need is a few minutes to spare and your slow cooker on hand to do the rest. If you like asparagus, you like soup, and you like having tasty leftovers to rely on mid-week, it’s a no-brainer.

I like to serve this savory soup with some of my Pretty Darn Perfect Sweet Dinner Rolls or my Classic Toasted Tomato Sandwich to really fill up those tummies!

How to Make Crock Pot Cream of Asparagus Soup

I don’t actually fry the onions or the garlic before I make this soup, and you can if you like. They both will cook in the slow cooker over the day and it saves you the time of frying them. If you enjoy caramelizing your onions before you add them to soup then, by all means, fry them up quickly and throw them in!

  1. Add the first 4 ingredients to the crockpot, combine, and cook on low for 6-8 hours.
  2. Puree the ingredients with a hand blender until smooth before serving.
  3. Stir in the cream/coconut milk until it’s completely combined.
  4. Serve with an extra dash of cream on top or my buttery garlic homemade croutons if you aren’t keeping this low carb.

How Do I Thicken My Cream of Asparagus Soup?

If you prefer a thicker soup, you can easily make a cornstarch slurry. Take 2-3 tablespoons of cornstarch and mix it with cold water until it’s smooth, then whisk it into the slow cooker rapidly. This will instantly thicken up the soup. However, this turns it from low carb into very carb!

How Do I Make Vegan Cream of Asparagus Soup?

It’s super easy to make this soup vegan! Just use vegetable broth instead of chicken broth and replace the cream with coconut milk.

How Long Do Leftovers Last?

Your leftover cream of asparagus soup will last for 3-4 days in the refrigerator. If you want it to last longer, you can freeze it making sure to use heavy freezer bags or airtight containers. Once frozen, this soup will last for about 3 months!

Tips and Tricks For Making Crock Pot Cream of Asparagus Soup

  • Sometimes I like to add a swirl of pureed roasted red pepper to the sour cream for that extra touch!
  • You don’t have to serve it warm, this soup is just as delicious served chilled.
  •  It’s hard to freeze soups that have a milk base, so try to freeze the soup WITHOUT the milk, then add it after when you defrost the soup base.

  1. susan says

    It needs more flavor. I added dill, 2t lemon juice and about 2 T parmesan cheese grated, 2 T sour cream and 1/2 c dehydrated potatoes to thicken it up. Reserved the tips of asparagus which I blanched and used for garnish, along with croutons and bacon bits. With all the additions, much tastier.3 stars

  2. Janet says

    You keep saying 5 ingredients. There are only 4 listed. What’s the 5th?

    • Regina Bauer says

      I was thinking the same thing, is there an ingredient missing of did it mean the first 3 ingrdients

  3. Lynn1974 says

    Anyone who would do this to two pounds of fresh asparagus is simply nuts.
