This recipe for Keto copycat Campbell’s Tomato Soup is the ultimate comfort food, but with only 86 calories and 4g net carbs.
Hello, soup lovers 👋
Today I’ve got a Keto tomato soup recipe to share with you. It’s a copycat version of the classic Campbell’s Condensed Tomato Soup. My Keto version is pretty darn close to the original.
If I do say so myself. 😊
But before we get to the recipe...
I've got a bone to pick with the Campbell's Tomato Soup advertisements. Growing up in the ’80s, the Campbell’s Soup catchphrase was “Soup is Good Food”. But I ask you, was "good" really the best thing they could say about their soup? Was it the best soup or even a great soup? No, it was just good soup. I truly don’t get it.
Let’s move on. 🤷♀️
In the soup 🥣
The Keto tomato soup that we’re making today is better than good, it’s great! It’s made from just vegetables, broth, and cream so it has only got 4g net carbs per cup. Compare that to Campbell’s Tomato Soup which has 43g. So... no contest.
Ingredients 🍅
- olive oil
- onions
- tomatoes
- vegetable broth
- tomato paste
- Swerve
- salt
- black pepper
- heavy whipping cream

Instructions 💬
- Heat olive oil in a dutch oven or soup pot over medium heat.
- Add onions and cook until softened, 5 minutes.
- Add broth, tomatoes, tomato paste, sweetener, salt, and pepper to the pan and bring to a low boil. Lower the heat and simmer for 30 minutes.
- Add soup to a blender and blend until smooth.
- Return to the pan, add cream and mix well.
Done! 👩🍳
The simple ingredients make the soup Low Carb, Keto, Vegetarian, and Low-Calorie. But how low in calories? How do 86 calories sound to you? Campbell's Tomato Soup has 329 calories and our much healthier tomato soup has just 86. Because you know what?
Keto Tomato Soup is Good Food! 🥰

Maggie says
This soup was really good. I didn't have the sweetener you used, so I used Allulose instead. Turned out great.
★★★★★
Emily Krill says
Oh, I like Allulose too. I tend to use Swerve, but not always. It can crystallize when it's heated, so I use Allulose for candy.
Carl says
This soup turned out jus like Campbell's soup! Thank you. Do you know of any low carb crackers I could eat it with?
★★★★★
Emily Krill says
You know what, HighKey makes some almond flour crackers that are very good. And if you are doing low carb rather than Keto, I like to eat Wasa Light Rye crackers which have 6g net carbs for each large cracker.
Beth M says
Mmmm, mmmm, Good!!! This soup is excellent, so much better than anything you could get out of a can. Even my non-soup-eating husband loves it! The only thing I did different from the recipe was to add about 1/2 tsp of garlic powder and a few shredded basil leaves from my garden. This is definitely a keeper! Thanks for sharing your recipe!!!
★★★★★
EmilyKrill says
Yum, fresh basil would be great with this soup. Thanks for the tip.
Judy says
Why did you add sweetener to soup?
EmilyKrill says
I added sweetener because Campbell's Tomato Soup is very sweet. It is also to counteract the acidity of the tomatoes. It's fine to skip it, but it does balance the flavor of the tomato soup.
Sandra says
Thank you for creating this recipe! So looking forward to trying this with keto grilled cheese sandwich! Just wondering if this soup be frozen so I can use in some adapted recipes in future?
★★★★★
EmilyKrill says
Yes, freezing it should be fine.
Marie says
What kind of tomatoes do you use?
EmilyKrill says
Any kind of tomato will work, except for cherry sized.
Debbie says
Made this today, makes 6 huge servings of soup, and you are right, it tastes better than the canned version with milk. Very creamy and tasty. Thanks for sharing the recipe.

EmilyKrill says
Sure thing! Thanks.

I’ve made this twice now. Living in North Dakota, tomatoes aren’t always great in the off seasons here. So I just use two cans of organic diced tomatoes. (I usually double the recipe too) I do tend to add only 4T of the swerve bc canned tomatoes seem to have a lot of sweetness too! I like to top it with basil and eat all night! Lol thank you for this

EmilyKrill says
Ha, thanks for the stars!
EmilyKrill says
Sure thing! It is a sweet soup, but the original Campbell's version is really quite sweet too.
Andrea Poythress says
I recently started keto and it was looking for a comfort inn tomato soup recipe so I was excited when I came across this one. It definitely is a lot more work than opening a can of Campbell's but I know that the end product is way better for me which makes it entirely worth it! I do prefer a creamier tomato soup so I doubled the heavy whipping cream. Additionally I added a tablespoon of butter at the end for a little more richness (I used to dunk buttered crackers into my tomato soup and always enjoyed the buttery flavor that they left behind). It was a pretty good substitute although next time I think I will add a little bit of garlic powder and see if that rounds out the flavor a little bit more. Thanks 😊

EmilyKrill says
Sure thing.
Karen says
Starred just for the Ren and Stimpy reference. Loved the soup and will definitely make again this winter.

If there is a chance to reference the Log song, I take it. Thanks for noticing!
