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.

As with every recipe I have tried from Lauren, this soup was delicious! The depth of flavor is awesome and it’s not a difficult recipe. For those who had lumpy roux, you must keep adding soup to your roux until it is smooth, before adding into rest of soup.
I have been trying to replicate a “cheesy, tomato soup with zucchini that we used to enjoy at a favorite restaurant before they closed. This is the closest yet! I added the zucchini (sliced or chunked into bite size pieces), and a couple of splashes of dry red wine after the cream and cheese were blended and simmered a few minutes to soften the zucchini. Delish!
I’ve been sick for the last couple of days so I needed something with some good potassium and vitamin C kick! This soup is absolutely amazing. I added some smoked paprika, garlic, and chili powder along with the other seasonings to further invigorate the warmth of this soup. I couldn’t be happier with how this turned out. Thank you so much for sharing!
There’s a local restaurant that made a cream of tomato basil soup that I loved so much I went looking for something to make at home. I have to tell you, this is NOT restaurant quality–it is BETTER. Having made this, the last time I ate at that restaurant, I thought their soup was sort of MEH!
Lovely soup, thank you! I added minced garlic, garlic salt, used roasted tomatoes along with a roasted red pepper. Added some red pepper flake for heat.
I cooked outside in crockpot so as to not heat up the house. Brought it in to finish so it cooled down a lot–to perfect warm temp for a hot day. I served it with garlic bread heated on the grill.
Absolutely delicious!! My husband says it tastes like a $20 soup. Will be making this for small gatherings in the future. Can’t wait to eat it again!
Is there a way to make this vegan? Thx!
You can use vegetable broth, coconut (or another vegan milk) and vegan cheese!
Tried this recipe was very tasty
Will definitely make again and add to my meal list.
BEST tomato soup I have ever eaten!!! This recipe is easy and AMAZING!!!
