Tomato Parmesan Slow Cooker Soup is a delicious vegetarian comfort food meal that the whole family will love.
On a particularly busy week, the ease of making Tomato Parmesan Slow Cooker Soup in the {affiliate} crock pot or slow cooker is just so awesome!
Serve this bread with some homemade Dakota Bread. Find the recipe for Dakota Bread here.
And when the soup comes out as tasty as this one, well, you have a winner – easy and yummy! everything you could want! Especially when it’s so cold out and you just need something warm in your tummy.
And, in full disclosure, I am fairly awful at making roux, so my awesome husband always makes the roux for me. Thanks, Dan!

Fresh bread to go along with this soup
When I make something in the crock pot, I like to make bread in the {affiliate} bread machine at the same time. Then, when it’s time for dinner, everything is all fresh and hot!
These Buttermilk Dinner Rolls can be made as a whole loaf of bread, and would it’d be awesome to make the leftover bread into French Toast the next day.
Milk of your choice
Use the milk of your choice: half and half will make a thicker richer soup that’s higher in calories; skim milk will make a thinner soup that’s lower in calories. I like the compromise of whole milk in this soup. You could even use a non-dairy milk like canned coconut milk (that would give a great thick soup), or almond milk.

Looking for more delicious crock pot soups
I love the slow cooker, and I think soups made in it are terrific! Here are some of my favorites: Slow Cooker Creamy Tortilla Soup, Crock pot Meatball and Potato Soup, and Crock Pot or slow cooker Broccoli Cheese Soup.
How does this soup look so smooth?
There are chunks of carrots, onions, and little bits of tomato in this soup. It is not a pureed soup. (though, using crushed tomatoes in the soup as the base makes it look very smooth.)
Because the chunks are heavy, they have sunk down in the bowl. If you look closely there are some carrot bits sticking up.
Now, if you want a pureed smooth soup, you can pop this in the blender, or use an immersion blender on it.

Tomato Parmesan Slow Cooker Soup Recipe
Tomato Parmesan Slow Cooker Soup
Ingredients
- 28 ounce can crushed tomatoes undrained
- 4 carrots sliced
- 1 large yellow onion chopped
- 1 teaspoon dried oregano
- 1 tablespoon dried basil
- 4 cups vegetable broth
- 1 bay leaf
- 1 teaspoon salt
- ½ teaspoon freshly ground black pepper
- ¼ cup olive oil
- ¼ cup butter
- ½ cup flour
- ½ cup freshly shredded Parmesan cheese
- 2 cups whole milk
Instructions
- Add first nine ingredients, tomatoes through black pepper, to the bowl of a 4-quart slow cooker. Cover and cook on low for 5-7 hours, or until vegetables are softened.
- About 30 minutes before serving the soup, prepare the roux. Heat oil and butter over low heat in a sauce pan and add flour. Stir constantly with a whisk for 5-7 minutes, until roux is a smooth light brown paste. Slowly stir 1 cup of hot soup into the roux, until fully mixed in. Add another 3 cups soup to the mixture, and continue to stir until smooth. Add thickened soup back into the slow cooker, and mix in the Parmesan and milk.
- Cover and cook on low for another 30 minutes. Taste for seasonings, and enjoy.

Damned ! I don’t speak English…:(
Catherine, I don’t speak French, sorry. But I did use this translator and it worked pretty well. https://translate.google.com/
This is one gorgeous soup! I, too, like to have my slow cooker and bread machine going at the same time. Makes the house smells amazing!
I love the color of this soup, i must try it soon!
This looks really good……can’t wait to try it! Quick question…..are you able to freeze it? I like doing big batches and freezing into portions for my lunch box! Thanks!
Amy, Thanks! I haven’t tried freezing it, but I think it would work just fine. I freeze most of the soups I make because there are only two of us eating here. I say go for it. I can’t think of any reason it would go badly freezing it.
Amazing recipe! Its absolutely delicious!!! Thank you 🙂
Britney, thanks so much for taking the time to let me know you loved it! You’ve made my day! 🙂
I’m so excited to make this tonight! In the picture it looks like it’s puréed, but I didn’t see that in the instructions. Do you purée it? Thanks!
Jenny, I don’t puree it (I’m too lazy to go to that extra step hee hee). The crushed tomatoes are almost like a puree or a sauce, so there’s no need to. It does have chunks of carrots & onions that have sunk to the bottom of the bowl so you can’t see them in the photos. You’ll love this! Thanks for the comment.
I had no idea tomato soup was so easy to make in a slow cooker, looks delicious! Thanks for the recipe.
This soup looks so comforting and inviting! Its color is simply amazing!
With the rain coming in this weekend, Tomato parm soup will be on the menu. Sounds so delish and I haven’t used my crock in ages!
This was pretty good! I used half & half & 2 cups was *way* too much. Next time I’ll use 1 cup or less. Like others have done, I used an immersion blender and came out with a very good texture!
I was skeptical of the carrots but read someones post, and it was delicious. YUM!
Recipe was good, first time I ever had a hearty tomato soup. I ended up putting at least half in the blender and blending it up for a creamier texture.
Yummy to my tummy
I made this in a pressure cooker instead of a slow cooker and followed the ingredients exactly…. cooked in 30 min and just incredible. Loved it!!
Add cooked ravioli to your bowl of soup!
Family thought this was one of the best soups ever,
