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!
Overall good but a little bland. Definitely needs more flavor. Added a lot more salt and some garlic powder.
Needed way more tomato flavor
My husband and I LOVED this soup with grilled cheese sandwiches. Turned out even better than I expected 😁Thanks for a great soup recipe!
Definitely tasted like a high end restaurant. Delicious!
I love this recipe! My family devours it every time. The only thing I change, is I add an entire small can (6 oz) of tomato paste. Like others have said, it didn’t have enough tomato punch for me as originally written. I now make a double-batch and share with the neighbors because they love it, too!
This is not easy for me because I have prepared many of Lauren’s recipes and they have all been delicious! This one was just ok to me. Although, tomato basil soup is a favorite of mine so it may be that I am particular when it comes to it. The tomato did not shine. It was heavily muted by the roux, cheese and carrots. I’m sure many people will like this recipe but I like a more basic tomato basil soup. I have much gratitude for Lauren’s meal plan and cannot wait to try the next recipe from Tastes Better from Scratch!
L0ve it just as it is. And it was easy. Adding spinach sounds good. I will serve with a little rice or velveta
I thought this was delicious and easy! I think next time I will add more tomatoes though to have the tomato flavor come through some more 🙂 Thank you!
This an excellent tomato and basil soup. On those cold winter days it will definitely warm you up. If you serve this to your guests. They will ask for the recipe. Thank you for sharing your recipes. Your recipes are the best.
Can this soup be frozen and thawed for later consumption?
I’d freeze it before adding the roux (freezing with the roux will change the texture slightly.). Reheat on the stove or in slow cooker and then add the roux.
We just found your site on Sunday, we started Week 1 and all three meals thus far have been great, thank you!
Not realizing how much this makes, I wish to freeze the remainder. Do you think that if I let it thaw overnight and then used the emulsifier again it would be “good as new”?
Thank you again!
We haven’t personally tested that but it sounds like it may work! Please let us know if you do! Thanks for checking out the meal plans, we’re thrilled you’re loving them!
