Why you'll love it

Don't you just love discovering keto recipes for things you thought were off-limits? I know I do!

Is tomato soup keto? Not normally. Canned tomato soup is super high in carbs and sugar, thanks to the tomato concentrate.

Low-carb tomato soup uses lower-carb ingredients with the same robust flavor but a fraction of the carbs. In fact, you can enjoy this with a grilled cheese sandwich - you just have to use low-carb bread.

Whenever you are craving creamy tomato soup, make this zesty recipe. You won't believe how easy it is to make! It's way better than canned tomato soup.

The herbs and spices work together to fill your kitchen with alluring aromas that draw you to the stove. The most difficult thing about this soup is waiting for it to heat up.

Ingredients

ingredients for keto tomato soup.

Here is what you'll need in order to make homemade tomato soup. Some of the ingredients might surprise you. Trust the process; the result is incredible!

Low-carb marinara sauce

Surprise! The base of this tomato soup is actually a marinara sauce. It works incredibly well.

Look at the ingredients label. Only use a marinara sauce that doesn't include any added sugar.

You could even make your own homemade marinara sauce! It's so easy you'll wonder why you ever bought the stuff from the store.

Heavy whipping cream

This is what makes it creamy tomato soup. If you don't have heavy whipping cream, you can use half and half.

Tip: To keep it vegetarian, use coconut cream instead.

Chicken broth

The chicken broth adds more layers of savory flavors to the soup. Chicken stock has a fuller flavor, so use that if you can.

Tomato paste

There is only one tablespoon in the entire pot of soup, so it won't affect the net carbs in each serving very much. This is more or less to enhance the tomato flavors.

Italian seasoning

Since marinara sauce and chicken broth already have plenty of salt and spices, you don't need very much Italian seasoning. It's basically to boost the aromatic properties.

Crumbled bacon

This is an optional topping for the soup. I think bacon adds a delightful crunch!

Fresh parsley

Chop some fresh parsley and sprinkle it on top for a lovely pop of color (and flavor) on the soup. You even mix it up and add some fresh basil.

Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.

Tips

  • Taste the soup before you add the Italian seasoning. It might not need very much seasoning, especially if you use a robust marinara sauce.
  • Let the soup boil before adding the heavy whipping cream. This will naturally thicken the sauce.
  • Do not let the soup boil after you add the heavy whipping cream. If you do, the cream might scald, which deteriorates the quality of the soup.
  • Add a dash of olive oil. This will make it a little creamier and richer.

Instructions

This super simple recipe makes creamy keto tomato soup easier than ever. Follow along; I'll even share step-by-step pictures.

Place marinara sauce on the stove

Place the low-carb marinara sauce in a pot over medium heat on the stove.

Add spices and let it boil

Add whipping cream

Pour in the heavy whipping cream, reduce the heat to medium/low, and simmer for 10 minutes.

Serve garnished with parsley and crumbled bacon if desired.

Serving suggestions

This tomato soup is the perfect thing to serve for lunch. Enjoy it with some grilled cheese sandwiches (made with keto bread, of course).

Soup and sandwich is a classic lunch idea. Instead of grilled cheese, make a keto panini. Or, go the soup and salad route and serve it with some pesto chicken salad wraps.

This tomato soup is also the perfect starter for any Italian recipe you want to make. Enjoy it before a dinner of keto meatloaf or some meatballs and marinara sauce.

Want something that's meat-free? How about eating this soup with some keto cauliflower mac and cheese? It's a fabulous pairing!

Variations

There are a lot of different ways to make this tangy keto tomato soup recipe. Here are some of my favorites! If you make any changes to this recipe, please let me know in the comments.

  • Garnish with chopped fresh tomatoes. A few of them will liven up the look of the soup and give it a little more texture too.
  • Make it vegetarian. Use vegetable broth instead of chicken broth and coconut cream instead of heavy whipping cream.
  • Make it spicier. Sprinkle some red pepper flakes and cayenne pepper into the soup.
  • Use it as a base for other soup ideas. Fill with keto noodles and ground beef for a beefy tomato and noodles soup.
  • Make a roasted tomato soup recipe. Garnish with a few fire-roasted tomatoes.
  • Garnish with fresh basil. This is the perfect addition to the fresh parsley.

FAQs

Here are some questions people usually ask about making tomato soup on the ketogenic diet. If you don't see your question in this list, please leave it in the comments.

Are canned tomatoes keto-friendly?

When it comes to canned tomatoes, it's all about portion control. A few bites won't throw you out of ketosis, but the entire can might. Use self-control, and you'll be alright.

How do you make a silky smooth soup from marinara sauce?

I love soups that have some texture to them. If you want it to be extra creamy (like Campbell's tomato soup), I suggest running it through a food processor or blender first.

Is bone broth keto?

Yes, bone broth is a keto-friendly soup base. You can use it instead of chicken broth for a full flavor in this tasty soup.

How big of a pot do I need to use for this soup?

All of the ingredients will fit easily into a Dutch oven. Use a medium or large pot for this soup.
