If there was ever the ultimate comfort soup, this bowl of deliciousness would be a serious contender.

We go with a combination of fresh tomatoes and canned crushed tomatoes for the perfect taste and texture. The fresh basil and stock are just the right amount of balance to the soup. The cream adds depth and luxuriousness. And, once you’ve roasted the tomatoes, the soup comes together in about 30 minutes!

HOW TO MAKE ROASTED TOMATO SOUP

Roasting the tomatoes for this easy tomato basil soup delivers a deeply satisfying taste for the soup.

You can really go with any type of tomato here, but we find Roma tomatoes work best. And, they are typically available all year.

ROASTING THE TOMATOES IS EASY

Simply preheat your oven to 375°F, line a large baking sheet with foil, and slice the tomatoes in half.

If using whole tomatoes, then cut them into thick (½-inch) slices. Drizzle with olive oil and then sprinkle them with salt and pepper. After baking for 1 hour, they will be tender and perfectly cooked.

EXPERT TIP: The tomatoes can be roasted in advance, up to 24 hours. Once the pan is cool enough to handle, cover the tomatoes with either kitchen towels (not pressing down on them), or with plastic wrap. When ready to use, carefully transfer the roasted tomatoes with a spatula (or your hands) from the baking sheet to the pot.

After sautéing chopped onions in olive oil, throw in 4 minced cloves of garlic along with some chopped fresh thyme.

Next goes in a large can (28 oz) of crushed tomatoes and the fresh basil.

Season with salt and pepper and let simmer for just 10 minutes.

FRESH TOMATO BASIL SOUP IN ABOUT 30 MINUTES

Once the canned tomatoes have simmered with the basil, it’s time to add in the roasted tomatoes.

Add the stock and let simmer on low for 20 to 30 minutes.

We’re getting close, folks!

To reach the right consistency, we use our immersion blender.

EXPERT TIP: You could also purée the soup in a blender or even a food processor. Using either of these appliances will give you a very smooth texture. The immersion blender allows you to make the soup as smooth, or textured, as you desire. Whichever method you opt for, use caution. The soup is hot and can splatter and cause a burn if it reaches your skin.

A final addition of heavy cream adds a depth of silkiness and taste that makes this the best-ever creamy tomato basil soup recipe on the planet.

The soup is now ready to eat, or you can keep it at a low simmer until ready to serve.

EXPERT TIP: You can substitute whole milk or half-and-half in place of the heavy cream. The finished soup will not be as silky, and the cream does add a layer of taste that we think is wonderful, but the other options are fantastic, too. For a completely dairy-free version, don’t add the cream or milk at all.

THE PERFECT SOUP FOR ENTERTAINING

This soup is so satisfying and always gets rave reviews when we serve it to guests.

Silky, cream, and layers upon layers of taste.

And it’s so easy to prepare!

ROASTED TOMATO BASIL SOUP FAQs

  • Can I use only canned tomatoes? Yes, but you won’t get the deep roasted taste from roasting fresh tomatoes. If using only canned, skip the roasting steps of the recipe and go with two 28 oz. cans of tomatoes, we recommend one can of crushed tomatoes, and one can of whole tomatoes, preferably San Marzano (make sure the can is labeled “certified”).
  • What about dried herbs, can I use them? For the thyme, absolutely, go with 1½ teaspoons of dried. For the basil, you won’t get those beautiful specs of basil, and the flavor won’t be as robust, but in a pinch, you could go with ¼ cup of dried basil.
  • How do you make those delicious looking croutons? Cut a loaf of bread into thin slices. Cube the slices (2 or 3) and place them in a bowl. Add 1 tablespoon of olive oil, 1 minced garlic clove, and a pinch of salt and pepper. Preheat oven to 400°F and bake until golden, flipping once – about 8 minutes.
  • How long will the soup keep? As with so many soups and stews, this gets even better the next day. It will keep in an air-tight container in the refrigerator for up to 1 week and freezes beautifully for up to 2 months.

Equipment

  • Large Dutch oven, or soup pot

Ingredients

  • 9 Roma tomatoes sliced lengthwise
  • 3 tablespoon extra virgin olive oil
  • 2 tablespoon unsalted butter
  • 1 yellow onion diced
  • 4 garlic cloves minced
  • 1 tablespoon fresh thyme minced
  • 1 teaspoon Kosher salt
  • ½ teaspoon ground black pepper
  • 1 28 oz. can San Marzano tomatoes crushed
  • 1 cup basil fresh, roughly chopped
  • 1 tablespoon sugar
  • 2 cups chicken stock
  • ⅔ cup heavy cream

Instructions

  • Preheat oven to 375°F.
  • Spread tomato halves on a baking sheet. Drizzle with olive oil, and then sprinkle with salt and black pepper.
  • Roast tomatoes for 1 hour. Remove from oven and set aside.
  • Heat 2 tablespoon oil, or butter, in a large pot (or Dutch oven) over medium-high heat.
  • Add onion, and saute for about 5 minutes.
  • Stir in the garlic, thyme, salt, and pepper. Sauté for another minute.
  • Add crushed tomatoes, basil, and sugar to the pot. Lower the heat and simmer for about 10 minutes.
  • Add the stock and the roasted tomatoes into the pot. Simmer for 30 minutes, stirring every now and then.
  • Use an immersion blender to purée the soup, or very carefully transfer to a blender or food processor to purée. This would most likely need to be done in a couple batches. Return the soup to the pot.
  • Stir in the cream.
  • To make the mini croutons: Cut a few small pieces of bread in small cubes, add a little oil, diced garlic and basil...bake at 400 for about 7 minutes... these make wonderful croutons!
  • Add the croutons to the top of the served soup. Serve at once!

Notes

We find fresh Roma tomatoes are perfect for roasting, but most tomatoes will work.  Thick slices are best.  Be sure to cut away any brown spots, especially on the top of the tomato.  The roasted tomatoes can be made up 1 day in advance, but we think using them within a couple of hours or roasting is best. 
Fresh thyme and basil is always best, but if using dried, then reduce the thyme to 1½ teaspoons and ¼ cup of dried basil. 
Whole milk, or half-and-half can be substituted for the cream, although the soup won't be as silky and the taste not as rich, but will still be delicious.
Substitute vegetable stock/broth for the chicken stock to make the soup 100% vegetarian. 
The soup will keep in the fridge for up to 1 week and freezes beautifully for up to 2 months.

    My family and I LOVE this soup! I have shared this recipe repeatedly in the the two weeks since I discovered it and made it for the third time tonight!
    This time I doubled the recipe so we can enjoy it for a couple more days, I added a quarter teaspoon of baking soda to cut the acidity a bit more, added half of the fresh basil with the tomatoes to simmer and the rest at the end before blending- it was perfect!! Love the roasted tomatoes and fresh basil. I make cheesy garlic bread for dunking and we also enjoy a bit of fresh shaved asiago on top of our steaming bowls of soup. It is comfort food and brings us all together at the table. THANK YOU!!

    I LOVE your Roasted Tomato Soup!!! My family loves it too! We our using the last of the tomato’s from the garden. My daughter requested your soup today as there’s a nice crispness in the air and as fall as arrived here in Georgia. It will be back up to 89 degrees next week so it’s a great day to make this most perfect soup.

    This by far hands down is the best tomato soup I have ever tasted . It is loaded with rich roasted tomato flavor and the cream makes it a winner. You said it was Loon Approved it is also Grandson that is a VERY picky eater Approved. I almost feel over when I asked him what he wanted me to make him for lunch and he said that tomato soup you had me try the other day.
    Great Job guys . I will be adding more of your recipes to my arsenal for happy grandbabies and my husband too.
    I love both of your energy and your love for each other it really stands out.
    Thanks so much for sharing.

    So here’s the thing, I’m a picky person. I don’t like tomatoes that much, but this was incredible. It changed my mind about tomato soup. It was honestly fantastic. I had this with a brie grilled cheese, pesto, and roasted red peppers. It was lovely. Thanks so much for this recipe!

    I came across this recipe on Pintrest and decided I had to try it after watching you make it and how easy it was. I followed your recipe to a tee, the soup is exceptional! My husband thought it was phenomenal. I normally post my kitchen creations on IG. I got so excited to try the soup that I forgot to take a picture of it in my Dutch oven before ladelling it in bowls. Perfect soup for the cold NY winters!

    This was absolutely, by far, the best tomato soup I ever had — the rich texture of the roasted tomatoes coupled with the flavor enhanced by the San Marzano tomatoes added to the texture of the soup and I was transported to Tuscany. I made it twice in two days so I could share with my neighbors confined to their homes due to COVID. Thank you.
