This easy tomato basil soup recipe couldn’t be simpler. I got the recipe from the cooks at St. Mary’s in Sewanee, Tennessee many, many years ago. I love to serve it with toasty grilled cheese sandwiches for a perfectly soothing meal at the end of a long day. 

All you need is four ingredients to make this creamy tomato basil soup: a can of tomato soup, a can of diced tomatoes, basil pesto, and milk. Simply add the ingredients to a saucepot and let them simmer. In 30 minutes it’s ready to serve to your hungry family as the main dish. Or perhaps it will become your new favorite weekday lunch?

This soup is delicious with lots of tomato flavor. It’s also light, healthy, and vegetarian. It’s no tomato basil bisque, which uses cream to make it thicker, but it ticks all of my boxes! Plus, there’s no need for an immersion blender or roasted tomatoes like other tomato soup recipes out there. It’s the definition of easy, which is just how I like it.

Store soup leftovers in an airtight container in the fridge for up to 3 days. You can also freeze leftovers for up to three months. Thaw overnight in the fridge before reheating quickly on the stovetop.

Recipe Notes

  • Garnish your bowl of hot soup with cracked black pepper, fresh basil leaves, garlic croutons, or fresh parmesan cheese.
  • If you want to use fresh tomatoes instead of the crushed tomato can, you’re going to need to roast a handful of Roma tomatoes or plum tomatoes in olive oil and then blend them to make a homemade version of diced tomatoes. Then you’ve got yourselves roasted tomato basil soup.
  • Instead of whole milk, I’ve heard this works well with coconut milk.
  • For added flavor, add a teaspoon of dried basil or chopped fresh basil to the tomato sauce.

Recipe FAQs

What can I pair with a bowl of tomato basil soup?

This soup goes great with its best friend, i.e. a grilled cheese sandwich or some homemade cheesy garlic bread, but you can pair it with a whole bunch of other food.  Try it with an Italian salad. Cook up some ravioli and add it to the bowl. Tuna salad sandwich lover? Dunk it in this beautiful bowl. Or simply dip in a slice of crusty bread. The possibilities are endless. Feel free to dunk.

  2. Sewanne is how I found out about your website. My 1st trip to Sewanne was Jan. 2009 for the quilt retreat. I met your Mom there and she told us all about your new venture and gave us the site to visit when we got home. Well the rest is history. Moms; what would we do without them? I will be headed back this a week from today. Thanks for all the info of places to visit.

  4. This recipe made me giggle!!! It looks yummy but when I was newly married I want to impress my Hubby with my cooking talents! I found a recipe for a tomato bisque that was served at a Swiss ski resort.I started from scratch with fresh whole tomatoes and spent the entire day making this soup! When I served it to my Hubby, expecting rave reviews, he said….. ” Yum, Campbell’s tomato soup is my favorite!” Dang near divorced him!!!!!

  5. Thanks Christy for the tomato soup recipe. Tomato soup and grilled cheese sandwiches are always the best. sometimes when I don’t want the bread, it tastes pretty good to add the cheese (cheez whiz or canned cheese soup)right in the soup. I like to sprinkle cheyenne pepper on my soup and grab a handful of flipside crackers. (mmmmm good)

  6. About 5 yrs ago, a friend and I drove to Sewanee to see our mutual friend on her birthday, who is the USPostmistress at Sewanee. She took us to the campus cafeteria for lunch, where we were joined by her husband. After lunch, she toured us around town and to The Point where one can see for miles and miles.–quaint town!

    I’m getting the ingredients for the Tomato Soup, and serve to a friend, if I can find one who is willing to eat my cooking! I’ve signed up for FACEBOOK, but it’s new to me.
