If you want to further minimize the carbohydrate content of your tomato soup, you can switch out some ingredients for low-carb alternatives. 

How to Store Creamy Keto Tomato Soup 

If you want to make your keto, low-carb tomato soup in advance and enjoy it later, you can put it in a jar or any other airtight container and store it in the fridge. This should make it last another 4-5 days without going bad. If you need to store it for longer, you can opt to put it in the freezer and thaw it before dinner.

To reheat your creamy keto tomato soup, move it to a pot and heat it over medium heat. Stir slowly as you reheat to break up the chunks of heavy cream. You can also heat this tasty soup in the microwave. Just move it to a microwave-safe bowl and leave it to heat for 2-3 minutes. 

What to Serve with Keto Tomato Soup

Can You Make Keto Tomato Soup Paleo-Friendly? 

This keto tomato soup recipe can be adjusted to suit your dietary needs and preferences. If you’re on a dairy-free or paleo diet, you can swap the heavy cream out for coconut cream.

Alternative Ingredients and Instructions for This Low Carb Soup

You love tomato soup but not a fan of canned soup? Try out this absolutely delicious keto soup that's definitely a keeper. If you want to give it a little twist to make it your own, here are some alternatives that you can use:

You can use chicken broth or vegetable broth instead of water and blend until you've reached your desired consistency. Add a bit of coconut milk if it's not creamy enough but note that it will increase the soup's carb count.

Fresh basil works perfect for this recipe (dried basil is fine too). Feel free to play with different herbs and spices such as Herbs de Provence, bay leaf, a dash of garlic powder or onion powder, red curry paste etc. Whatever fits your taste buds!

  • You can substitute heavy cream with sour cream, Greek yogurt, or even cream cheese but the subs can change the total net carbs.
  • If you don't have a blender, use a potato masher. The result will be chunkier but you'll still have a delicious soup!
  • If you like the tomato flavor and want to intensify it, tomato paste is your go-to ingredient. It will also add to the creamy texture that we're looking for.
  • Remember to discard the skins if you opt for fresh tomatoes. Try to avoid store bought tomato sauce as its ingredients may not be good for keto diet.
  • Most people prefer San Marzano tomatoes. However, Roma tomatoes are also a good alternative especially for their paste-like texture.
  • It is possible to cook it in a slow cooker as well as a Dutch oven.
