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.
It’s also delicious with some Cheese Crisps. Check out my easy to make How to Make Cheese Crisps recipe!
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.

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.

Amazing recipe! Its absolutely delicious!!! Thank you 🙂
Jenny
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!
Debi
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.
Sharon
I had no idea tomato soup was so easy to make in a slow cooker, it’s delicious! Thanks for the recipe.
Katerina
This soup is so comforting and inviting! Its color is simply amazing! Easy to make too!
KC
With the rain coming in this weekend, I made this Tomato parm soup. So so delish and I haven’t used my crock in ages! It was a fun recipe to make!
Jordan
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!
Lori
I was skeptical of the carrots but read someones post, and it was delicious. YUM!
Morgan
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.
Kannelle
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!!

Just made this and I love it! Hubby doesn’t love the smell of it cooking all day but I guess that means I don’t have to share! I can’t wait to enjoy this with a yummy grilled cheese sandwich 🙂
