Hi! I'm Karen, a stay at home mom and blogger. Mostly I write about the new foods and recipes I've been making at my house. I like nutella, avocados, muddy buddies, mushrooms, tomatoes, peaches, berries, beans and rice, dark chocolate, cilantro, peanut butter, fried eggs and a million other types of foods. Most of the time, I like to make really easy and simple recipes--that's why I use my slow cooker a lot! I hope you find my posts helpful! Please comment and let me know when you make one of my recipes!

This is the most delicious soup ever!  Whenever I make it I get tons of compliments.  Serve alone or with grilled cheese sandwiches for a appetizing, comforting meal.

Tomato Basil Parmesan Soup

Makes about 2 quarts (about 8 servings)

  • 2 (14 oz) cans diced tomatoes, with juice
  • 1 cup finely diced celery
  • 1 cup finely diced carrots
  • 1 cup finely diced onions
  • 1 tsp dried oregano or 1 T fresh oregano
  • 1 T dried basil or 1/4 cup fresh basil
  • 4 cups chicken broth
  • ½ bay leaf
  • ½ cup flour
  • 1 cup Parmesan cheese
  • ½ cup butter
  • 2 cups half and half, warmed (or skim milk if you’re trying to cut some calories)
  • 1 tsp salt
  • ¼ tsp black pepper

1.  Add tomatoes, celery, carrots, chicken broth, onions, oregano, basil, and bay leaf to a large slow cooker.

2.  Cover and cook on LOW for 5-7 hours, until flavors are blended and vegetables are soft.

3.  About 30 minutes before serving prepare a roux. Melt butter over low heat in a skillet and add flour. Stir constantly with a whisk for 5-7 minutes. Slowly stir in 1 cup hot soup. Add another 3 cups and stir until smooth. Add all back into the slow cooker. Stir and add the Parmesan cheese, warmed half and half, salt and pepper.  Add additional basil and oregano if needed (the slow cooker does a number on spices and they get bland over time, so don’t be afraid to always season to taste at the end).

4.  Cover and cook on LOW for another 30 minutes or so until ready to serve.

Stove-Top Version of Tomato Basil Parmesan Soup

If you want to make this recipe on the stove-top you can!  Here is the adjusted recipe:

  • 3 cups diced tomatoes with juice (you can use canned)
  • 1 cup finely diced celery
  • 1 cup finely diced carrots
  • 1 Tbsp fresh oregano or 1 tsp dried
  • 4 cups chicken broth
  • 1/2 cup flour
  • 1 cup parmesan cheese, freshly grated
  • 1/4 tsp black pepper
  • 1/4 cup vegetable oil
  • 1 cup finely diced onions
  • 4 Tbsp fresh basil or 1 Tbsp dried
  • 1/2 bay leaf
  • 1/2 cup butter
  • 2 cups half and half, warmed (if you want you can use whole milk, evaporated milk instead…or even skim if you want to skinny it up)
  • 1 tsp salt

1.  Heat oil in 4 quart soup pot.  Add celery, onions and carrots.  Saute 5 minutes.  Add basil, oregano, bay leaf, tomatoes, and chicken broth.  Bring it to a boil, reduce heat and simmer until carrots are tender (15 minutes).

2.  While soup simmers, prepare a roux.  Melt butter over low heat, add flour and cook, stirring constantly, 5-7 minutes.  Slowly stir in 1 cup hot soup.  Add another 3 cups and stir until smooth.  Add back into soup pot.

3.  Simmer, stirring constantly, until soup begins to thicken.  Add Parmesan cheese and whisk to blend.  Stir warmed half and half, salt and pepper.  Simmer over low heat 15-20 minutes, stirring occasionally.

    This soup was delicious. Very easy to make. I used canned tomatoes and added garlic. YUMMY…totally going in my rotation. Thank you for sharing!

  3. impa 03/20/2013 at 10:05 am

    loved the soup, very easy, made twice already, second time i used almond milk to skinny it up and garlic it was just as delicious as the first time. Shared with my diet buddy and she loved it and told her bout the cream she said it was still very tasty.

  4. Rebecca 03/24/2013 at 11:05 am

    Could I use vegetable broth instead and it still be flavorful? My sister is a vegetarian and I like to share my leftovers with her.

    Others such as tomato paste, modified food starch, salt, yeast extract, caramel
    color, hydrolized soy protein, hydrolized yeast protein, beef
    fat, flavoring, hydrolyzed wheat gluten, dextrose are ingredients containing hidden MSG.
    According to these sites, the batteries and other accessories you’ll need can be purchased inexpensively on auction sites. Because the lid will be sitting snugly on the pot during the slow cooking, liquid will be generated as a by-product.

    I used roma tomatoes, liquified and poured into pot with chicken stock. The veggies were chopped and added to broth. No sauteing. Cooked on stove top on very low heat. The result..Like slow cooker..Added salt, pepper and skimmed milk…So very good..Will for sure make again but next time will double recipe..

  8. Karen Bonfield 04/08/2013 at 6:32 pm

    This is the best soup ever, and when you make it , double the recipe…trust me, you’ll want an extra batch in the freezer. I do think you can use half the amount of milk and flour for the roux though , it’s plenty thick for me even though I use 2%milk (regular and evaporated). Also, I use an immersion blender when it is done simmering, before I put the milk in, just to blend it all up a bit. A keeper for sure!

    Have you ever ended up freezing this soup? If so did it freeze well and still taste yummy? My navy bean soup freezes so good,I think it’s better on that soup to freeze(navy bean)

    This is a delicious soup you must try if you like cream of tomato soup.

    Is it possible to crock pot this soup on high to reduce the time?

    • Karen Petersen 01/02/2014 at 9:36 pm

      For sure. Just cook on HIGH for about half the time and it should be fine.

  34. Ann Garza 01/11/2014 at 9:20 pm

    Almost done prepping the this soup for the crockpot. Planning to start the crockpot in the AM and have it ready for lunch after church. Used crushed tomatoes and diced all veggies small, as I just dropped my immersion blender tonight. Totally broken, bummer. But looking forward to this soup and grilled cheese sandwiches on Sunday.

    This is the best soup ever! I make it over and over for my family. Tonight we are snowed in and I’m so glad I put this in the crockpot earlier.

    Hi Karen,

    Thanks for putting up this recipe and for taking such a lovely picture of it.

    Made the stove top version tonight with some changes.
    • added in a full bay leaf
    • added in one parmesan rind
    • only added in 1/2 cup of milk
    • added in some basil and parmesan tortellini
    • used margarine instead of butter
    • omitted the 1 cup parmesan cheese

    I found it quite creamy enough with the parmesan tortellini so I felt like I didn’t need to add in all the parmesan and milk.

    With all the changes it tasted great!

    Thanks again!

    Hi! I made this once and LOVED it. Now, I’m seeing that the tomatoes are listed as canS – plural – but no number in front of the 14 oz. Do you mean more than one can of those? Thanks for clarifying.

    • Karen Petersen 03/07/2014 at 11:12 am

      Oops!! It is supposed to be 2 cans!! Thanks for letting me know. I will correct it :)
