Soup Lovers Unite
My kids love tomato soup and chicken noodle soup. Offer them any other soup and it better be topped with enough cheese, crackers or croutons that it cannot be recognized as soup.
I am a soup and salad lover so this dislike of soup has meant that soup is generally not on the dinner rotation… until I started experimenting with tomato basil soup recipes.
Since my kids love tomato soup and pizza they would have to love tomato basil soup, right?
And they did, but I didn’t love all the fat in the traditional recipe.
Healthy Slow Cooker Tomato Basil Parmesan Soup
I created this recipe as a healthy alternative using six different kinds of vegetables that add creaminess and flavor to the soup without adding many calories or any added fat.
Don’t worry, the flavors of the vegetables blend perfectly with the tomato and basil so you get the traditional flavors of tomato basil.
I love secretly adding nutritious vegetables to my recipes to bulk up the flavor while still being kind to the waste line! (Check out my Ultimate Light Potato Soup Recipe for the Crock Pot, it also adds extra vegetables to a classic soup).

Throw and Go Slow Cooker Recipes
My favorite part about this recipe? It's throw and go: cut up the ingredients, add them to the crock pot, and dinner is done. No pre-browning or pre-cooking necessary. You can even place the ingredients in the slow cooker insert the night before, keep it in the fridge overnight, and then start it cooking on your way out the door.

This soup is amazing!! I love that I can toss everything in the slow cooker in the morning and come home to a delicious and healthy dinner. I usually make grilled cheese on the side and dinner is done!
Bren says
I love a toss and go slow cooker recipe and I agree grilled cheese on the side is perfect!
Amy says
Great recipe! Can you please clarify the size of a serving? 1 Cup?
Thank you!
Bren says
A serving is approximately a cup and a half. 🙂
Susan says
The flavor is delicious, and my husband marveled at how light the soup was. I served this with parm/gruyere souffles–this was perfect for dipping the souffle a spoonful at a time, kind of like an elevated grilled cheese and tomato soup. I started my crock pot a little late, and transferred the soup to my Le Creuset so I could crank it up in order to have it ready for dinner, so I’m sure the flavors blend even better when given the long cooktime.
Bren says
Thanks for commenting, Susan. I’m so glad you enjoyed the recipe!
Kelly says
Do you have to add thecorn starch?
Bren says
No, it just thickens the soup.
GwenEllyn Anderson says
There isn’t enough room in my crock pot – standard size to get all of this in. What happened? I’ll add it hopefully as the other items break down. Anyone else run into this?
Bren says
It will cook down as it heats up. The crockpot I use for the recipe is a 7 quart crock pot.
