Tomatoes are a bit too high in carbs to be eating a lot of on a regular basis. We’ve used butter and heavy cream to increase the fat levels, to make this less “low carb” and more “ketogenic” – be sure to check your macros because too much of this delicious soup could kick you out of ketosis!

Our Low Carb Tomato Soup can also be made in a slow cooker; after sauteing the onion and garlic, throw everything, except the cream, into your slow cooker. Cook on high for 3 hours or low for 7-8 hours, then blend and stir through the cream.

This Keto Creamy Tomato Soup recipe makes 6 appetizer serves. 1 serving is 7oz/200g and has 5g net carbs.

Store leftover Keto Creamy Tomato Soup in the fridge for up to 5 days, reheat gently over low heat on the stove. If you want to freeze the soup, we recommend not adding the cream, as cream and tomatoes do some funny things when frozen together – freeze up to 3 months.

    We have made this tomato soup several times and absolutely love it. The blend of flavors and creamy texture are just right. Easy to make. I’d like to say, however, we have frozen this soup as many times as we have made it. The thawed and reheated soup has tasted just fine and the texture was good, too. So, I say it’s worth trying to freeze one or two portions and see if you have any trouble with it. 😉
    Thanks so much for this recipe!
