This keto tomato soup recipe is delicious and ready to eat in under 20 minutes! It’s a quick, healthy low-carb appetizer, lunch, or dinner that everyone, even non-keto dieters, will love. You can make this keto tomato soup in an instant pot, slow cooker, or pressure cooker.
Tomatoes are a bit too high in carbs to be eating a lot of regularly. 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 six appetizer serves. One serving is 7oz/200g with 5g net carbs.

Notes
Nutrition
Store tomato soup in the fridge for up to 5 days, and 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 for 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!
Thank you for the kind words Trilby and for your tip, we’ll give it a go.
This tomato soup was amazing and so easy to make. I added an extra can of tomatoes (Mexican Recipe stewed tomatoes) to the mix and, since I don’t have an instant pot, I used a regular old fashioned stovetop pot.
I have tried two of the soups recently, (tomato and the broccoli & leek) both were lovely, so tastey. I can thoroughly recommend both.
Thank you 🙂
