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.

My husband said that this was the best soup he has ever had! It was perfect. We dipped our grilled cheese in it. Yum!
Is there a reason you use diced tomatoes instead of whole? Just want to make sure I have the proper ingredients.
Made your beautiful from scratch tomato basil soup. Im so inspired by great cooks on Pinterest. Im a single 71 year young woman. Still cooking after all these years. Always share the end product, and always let people know about the new way to research and cook.
I made this but I accidentally opened and used vegetable stock. This recipe is delicious and will be made again an again!! But next time I will use the chicken instead of vegetable broth my bad.. thank you for this amazing recipe❤️
I made this tonight and it was Delicious! I used altered the recipe a bit though. I used one can of regular diced tomatoes and 1 italian diced. I used 2 c of veg broth, one cup of water and 1 c of pino grio. I also used grated parm in the jar and used only 1/2c. I also only used half the butter and half the flour to make the roux. I didnt have to thin it out at all. it was perfect. I also only used one cup of half and half. I also threw in some leftover cooked cheese tortellini. Will definitely make again!
This recipe is perfect! I followed it almost exactly; the only difference was that I didn’t have low sodium chicken broth so I used regular, then added less salt at the end. This soup is creamy and delicious, will make again for sure!
The soup was amazing!! My husband and I really enjoyed how flavorful it was. I tweaked by adding 4oz of cream cheese. Thank you for sharing this awesome recipe!!
Wow. This was super yummy. I bought an immersion blender just for this recipe, and I am so glad I did. I will be making this again for sure!
This is our new favourite tomato soup recipe. I found it took longer to get the rue to the correct colour. I added no additional oregano or basil. Thank you for sharing.
The soup was amazing. I used 1% milk, and omitted the salt, and it was still it was rich and flavorful. I will definitely make this again.
Thanks for the “Serve With” box right before the recipe. I definitely like this format for the post. Figuring out what to serve with a main dish to make a real meal is always a challenge for me. The suggestion box makes this easy.
