This bold and ultra flavorful Creamy Tomato Basil Soup is out of this world amazing! It uses a lot of pantry staple ingredients, and can easily be made in the slow cooker, Instant Pot, or right on your stovetop. You won’t want canned tomato soup ever again!

This is one of mySouprecipes I know you’ll want to keep on hand!

Slow Cooker Creamy Tomato Basil Soup (1)

I’ve had this recipe on my website since 2014… in fact, it’s one of the very first recipes I shared!

We still make this creamy tomato soup often, and over the years, I’ve tweaked it slightly, changed things up to prevent any curdling, and developed more ways to cook this soup.

If you’re a fan of canned creamy tomato soup, let me tell you, you won’t want to buy those cans ever again after you try this homemade version.

The flavors are absolutely incredible! The acidic tomatoes, sweet basil, velvety cream, and salty Parmesan all come together in a bowl of pure deliciousness.

This soup is made in a slow cooker, but don’t worry, I’ve shared how to make it in the Instant Pot, as well as on the stovetop. No matter which version you make, you’ll love how easy it is!

How to make creamy tomato basil soup?

This is just an overview; the full ingredients and directions are in the recipe card toward the bottom of this post.

Slow Cooker Creamy Tomato Basil Soup (2)
  1. Add tomato soup base to slow cooker. That’s the diced tomatoes, tomato sauce, tomato paste, onion, garlic, basil, salt, pepper, and chicken broth.
  2. Slow cook. Cover and cook on low for 6-8 hours.
  3. Make roux. This thickens the soup a bit, and adds undeniable creaminess! Melt butter, then add flour and whisk. Whisk in the milk and cream and cook a few minutes, until thickened slightly.
  4. Add cheese. To the roux, add Parmesan cheese and stir until smooth.
  5. Pour roux into slow cooker. Give it a good stir, then leave it uncovered and cook about 20 more minutes, stirring occasionally.
  6. Serve. Serve hot, sprinkled with Parmesan cheese, and fresh basil.

Helpful Tip!

This soup will need to be blended once cooked, and there are several ways you can do that. My favorite way, and the most convenient, is to use an immersion/hand blender. You can blend the soup while it’s hot, and right in the slow cooker. You can also use a traditional blender, or food processor but you’ll need to take some precautions.

  • Let the soup cool a little bit, so there is less steam.
  • Only fill up your blender about halfway.
  • Remove the center cap of the blender lid.
  • Use a kitchen towel to hold the blender lid on.
  • Blend, then pour into a bowl.
  • Repeat with remaining soup.

Variations of this recipe

  • Non-creamy – creamy tomato soup not your thing? You can simply leave off the roux and dairy, and have a rich, traditional tomato basil soup.
  • Vegetarian – we like to use chicken broth as the liquid in the soup since it adds great flavor, but if you’re a vegetarian, swap that for vegetable broth.
  • Dairy – we like the combination of the evaporated milk and heavy cream, but feel free to play around with different types of dairy that you have on hand (milk, half and half, all evaporated milk, all cream, etc). I haven’t specifically tested with non-dairy milks, but I *think* they should work well.
  • Fresh tomatoes – in the summer, this soup can be made using fresh tomatoes if you have some on hand. You’ll want about 3 lbs of tomatoes (peeled or unpeeled, it’s up to you), and you can use less chicken broth (since the tomatoes will give off quite a bit of liquid as they cook). Obviously you can omit the canned tomatoes and tomato sauce, but I’d probably keep the tomato paste in, since it adds a deeper flavor.
  • Other cooking methods – as written, this is for a slow cooker soup, but you can easily make this recipe in other ways. Check out the “chef tips” section below the recipe for all the details (stovetop and Instant Pot versions).

FAQ’s

Is creamy tomato soup the same as tomato bisque?

Traditionally, bisque is made using a shellfish broth/stock. But in our more modern times, adding cream and thickening a soup can classify it as a bisque… which means this recipe can either be called creamy tomato soup, or tomato bisque. Whatever you call it; it’s delicious!

Will the dairy curdle when added to creamy tomato basil soup?

In this recipe, it shouldn’t. The extra step of making a roux, then warming the dairy before adding it changes the chemical makeup of the dairy liquid, which keeps it from curdling in the acidic tomato soup base. We are also using higher fat dairy, which further prevents curdling.

I’ve heard of adding baking soda to creamy tomato soup, what’s that for?

Adding baking soda is sometimes done to prevent any curdling. Tomatoes are, by nature, acidic, and high amounts of acid can curdle lower-fat dairy (such as 2% milk). Even just 1/2 tsp of baking soda will work, so if you are using a lower-fat dairy milk, it’s an option if you really want to be on the safe side. I promise, you won’t taste the baking soda!

Making tomato soup ahead of time

Soups are amazing to make ahead of time, since most of the time, they actually taste better the next day! All the flavors have had time to really meld together.

This tomato basil soup should last for several days in the refrigerator, so feel free to make it completely ahead of time if you’d like.

Storage

Leftover soup should be refrigerated in an airtight container and enjoyed within 4-5 days.

Reheat however you prefer (microwave, stovetop or Instant Pot).

Freezing

This tomato soup recipe can be frozen! Due to the dairy in it, I do recommend freezing it before adding the roux and cheese.

Let the soup cool completely, then transfer to a freezer-safe container, label with the date, and freeze for up to 3-6 months.

Thaw in the refrigerator, then proceed with the roux instructions and heat.

My Favorite Slow Cooker!

I had this crockpot for a while now, and I really love how it cooks. The locking lid feature is amazing for taking foods to potlucks or other gatherings!

    This has been a family favorite in my home since discovering it on your blog years ago. Simple recipe, simple ingredients, RICH flavor… so rich that it just “ruins” any other tomato soup recipe. As a family we’re just not even interested in trying other ones, this one right here is the HOLY GRAIL.

      I have one for the condensed version that people use in casseroles (like green bean casserole), but not one for a more traditional soup (yet). https://www.thechunkychef.com/condensed-cream-of-mushroom-soup/

    Oh my goodness! Just got done making this incredible creamy tomato soup! It’s just heaven. I had to make a couple of adjustments because I didn’t have all the ingredients. I did add a 1/2 teaspoon of baking soda and it does make a difference. I substituted 2 cans of tomatoes with chili. It gave the soup a nice little kick. The cream mixture cut back the heat as well. I’ve been buying Progresso Creamy Tomato soup with basil at Walmart! No longer will I need to spend that extra money. Thanks so very much! I’m a fan!

    Wow – I made this for our meatless Friday during Lent and now think this is my favorite soup I’ve ever made! My only changes : used basil from the little squeeze tube bc we had it onhand and I swapped out the cheese – I like things with a kick so I grated Colby Jack instead of parmesan and it is LOADED with flavor…have to stop myself from continuously going back for more! Thank you for sharing – definitely will be making again (and again, and again…😋)

    Great and easy soup! I halved the recipe and it fit great in a 4 quart crock pot. I didn’t have basil so I added a dash of Italian seasoning. Yummy!

      As long as it’s an amount equal to both the diced tomatoes AND tomato sauce.

    This was delicious Amanda as all your recipes are. The only thing I did different was turn it on high after I added the roux mixture and took the cover off so it would thicken just a tad more. I also used fresh tomatoes from the garden, left the skins on, the seeds in and everything just combined well with the immersion blender. Think I am going to try your cheddar broccoli soup this weekend. Thanks for all your delicious recipes!

    Hi Amanda, what brands do you like to use for the tomato sauce? Also, over the summer I jarred 32 oz. of unpeeled tomatoes with the seeds in. Can I use that jar as a substitute for any of these ingredients? Thank you!

    • The Chunky Chef says

      I typically use Hunts, Cento, or Dei Fratelli brand, but you can use any of your favorite brands. You could absolutely use the tomatoes you canned, I would use that in place of the diced tomatoes, although you’d want to remove the skins and just break up the whole tomatoes with a wooden spoon or potato masher 🙂

    I’ve been using this recipe for almost 7 years now. A friend brought it to us when my son was born and my whole family was hooked. It is our absolute FAVORITE soup and I have made it numerous times for events. Every time we share it with someone new they ask for the recipe. It is the most delicious tomato soup you will ever put in your mouth!
