    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 💬

    1. Heat olive oil in a dutch oven or soup pot over medium heat.
    2. Add onions and cook until softened, 5 minutes.
    3. 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.
    4. Add soup to a blender and blend until smooth.
    5. 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! 🥰

      Hello, we’re going to try your recipe and cannot wait! I would like to double the ingredients. Will this freeze well? Sorry if I missed. Thanks!

        Great! Yes, it freezes well. There is a way to easily double the recipe. Look on the recipe card for the button that says 2X. That’ll give you twice the amounts so you don’t have to do the math.

      I don't have the sweetener you used. Will it taste ok without it?

        Oh, it'll be fine. But Campbell's tomato soup is so sweet, you really need a little sweetener to get the flavor just right.
