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 had planned on making this soup today but I woke up late and didn’t have prep time. I was anxiously scanning the comments section in hopes of finding a stove adaptation and now I’m so glad I did. Thanks for adding it, now I can rush home and make the soup after work!
How would I change the cooking time if I was making this on the stove?
Hi Karen, to make it in a saucepan, add all of the veggies to the pan and saute. Add the tomatoes, paste, chicken broth and seasoning and cook until the veggies are tender. Make and add the roux according to the directions.I would blend it at this point (if you want to blend it). Then add the half and half, parmesan and any other spices, to taste. Heat through.
Enjoy!
We made this for dinner tonight and my family LOVED this soup!! I did not blend it at the end though, I served it right out of the crock pot. It was just as delicious. They were already asking when I will make this again!
Very happy to hear it! Thanks for commenting 🙂
Just made this and it is delicious!! No need to puree if you like it a little chunky. I also added 1 TBS of minced garlic.
Made this for dinner this evening with grilled ham and cheese sandwiches… It was AWESOME! I used only 1/4 cup of both the flour and butter in the roux. The veggies make it so filling and secretly healthier, and I was so pleased!! I used an immersion blender which made for easier cleanup…. Can’t wait to try it with fresh tomatoes and basil in the summer! Thanks so much!
YUM! My mom recently told me she cuts down the butter as well–glad you liked it! Thanks for commenting!
What is Half & Half? I’ve never heard of it here in the UK! Loving the sound of this soup and any comfort food that can be made in the slow cooker is always a winner!
It is basically half cream, half milk. You could substitute half cream and half milk, or you could even use evaporated milk 🙂
I made this in my Vitamix. I made the roux on the stovetop to prevent a “floury” taste. I then put all the ingredients, including the roux, into the Vitamix–except the broth and Parmesan cheese. I ran it until it was very, very hot. Then I added the cheese and pulsed several times. The cheese did not melt entirely, which was perfect. I completely omitted the broth!! The result was a very thick, restaurant-quality, amazing soup!
Thanks for commenting–your adaptions sound wonderful 🙂
Could the first part be turned up to high for a bit to cook the soup faster?
Hi Anna, Do you mean could you cook the first part in a pot rather than the slow cooker? Yes, you could!
I added a small can of tomato paste, one additional cup of broth and more salt and pepper. Then, 1/4 cup 25 year balsamic vinegar… Delicious!
This sounds delicious! Do you think I could substitute heavy cream for the half and half? It’s in my fridge and half and half is not 😛
Hi Kim, that should work great!
