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.
