This creamy Tomato Basil Soup is loaded with hidden vegetables and is restaurant-quality DELICIOUS! You can make it on the stove, slow cooker or in the Instant Pot.

How to Make Tomato Basil Soup:
- Sauté the vegetables: Add the carrots, onion and celery to a pot with a little bit of oil and sauté them for a few minutes.
- Add: diced tomatoes, tomato paste, chicken broth, oregano, and basil. Bring to boil and cook for several minutes, until the vegetables are tender.

- Blend. Use an immersion blender or regular blender (you may need to do this in batches, depending on how big your blender is) and purée the soup until smooth. Return it to the soup pot.
- Make the roux: In a separate pot, add butter and melt on medium heat. Stir in the flour and whisk together constantly for about 10 minutes or until the roux is a nice golden brown color.
- Add the roux: Stir a big ladle full of soup into the roux-it will start to form a thick paste. Slowly add another 2-3 cups of warm soup to the roux, whisking it until smooth. Add the mixture to the soup pot and stir well to combine.

- Stir in parmesan cheese, half and half (or milk), and salt and pepper. Add additional oregano and fresh basil as desired, to taste. Stir well. Cook for a few more minutes until warmed through.

For Slow Cooker Tomato Soup:
- Add to slow cooker: diced tomatoes, carrots, onions, celery, tomato paste, chicken broth, oregano, and basil.
- Cover and cook on low for 5-6 hours until flavors are blended and vegetables are soft.
- Make the roux: About 30 minutes before the soup is ready, prepare a roux. Melt the butter over medium low heat in a skillet and add the flour. Whisk together constantly for about 10 minutes or until the roux is a nice golden brown color.
- Thicken soup. Slowly add 1 cup of the soup from the slow cooker to the roux–it will start to form a thick paste. Slowly add another 3 cups of warm soup to the roux. Whisk together until smooth. Add the roux mixture to the slow cooker and stir to combine.
- Blend: Pour soup into blender (you may need to do this in batches, depending on how big your blender is) Purée until smooth. Return to the slow cooker.
- Stir in the Parmesan cheese, half and half (or milk), and salt and pepper. Add additional oregano and basil if needed, to taste. Stir well.
- Finish cooking. Cover and cook on low for another 20-30 minutes or until warm.

I originally shared this recipe December 2013. Updated September 2019.






My husband said that this was the best soup he has ever had! It was perfect. We dipped our grilled cheese in it. Yum!
The whole family loved it! Even my oldest, that doesn’t like soup! We will definitely be making this again! Thanks for sharing the recipe! ❤️
Turned out well enough, but I would reduce or probably eliminate the parmesan altogether in the future as it overwhelms the tomato and makes the soup too rich and heavy.
Added crab to this and Yaouza!!!!! It then became crab Bisque! Wonderful!
This soup is amazing – it’s the 4th time I’ve made it this month – going to freeze the batch I’m cooking this morning – it is wicked cold and this is just the ticket. I did have some fresh basil – threw it in to add even more flavor! 😋
Love this soup! It is a staple for my family. The only change I made was I do fire roasted tomatoes! It adds that little kick this soup needs.
However I do have one question… how much soup in oz/g/cups is the serving size?
I made this soup over the weekend and will make it again with some slight changes: 1/2 the amount of onion (or less) and I added Greek seasoning to taste. I found the original recipe to be lacking in flavor hence the Greek and overpowering in onion. I toasted parmesan bread with butter and additional Greek seasoning. Perfect paring!
We liked the soup, but I think next time I will skip the step of making the roux, and just add the milk to give it that creaminess. The flavor was great though.
Made this today when I was hankering for tomato soup. Delicious!
Question, can this be frozen? I was thinking of freezing individual portions in my vacuum seal bags so I can enjoy it at work for lunch.
So glad you loved it!! Yes, you can freeze it but it’s best frozen without the cream and shredded cheese. You can find instructions in the post on how to freeze it!
Made this recipe for my annual girls soup party and it was such a hit, that the left overs were my parting gift! So flavorful and paired well with a parmesan crustini!
This soup is excellent. Made it exactly as recipe states and it was perfection. Great flavor. My husband wanted a second bowl.
The roux ruined my soup. It tasted amazing until I added it to the roux. Wish I would have left it out 🙁 it’s completely unnecessary. However, the veggies puréed together was great. Would make again without the roux.
