Broccoli Cheddar Soup has long been a favorite of mine, next to Cheesy Cauliflower Soup, of course. Little did I know about all the extra carbohydrates in a soup that you might think would be relatively low in carbs. Just how many carbs are in broccoli cheese soup? 

About 20-30 grams of carbohydrates per serving in traditional Broccoli Cheese Soup.

Most broccoli soups have a good amount of carrots and flour. Some even have added sugars. So you can see how easily the carbs can add up.

I’m not calling this a Panera Bread copycat recipe, but I will say that my very picky child, who loves Panera Bread’s Broccoli Cheddar soup, loves this recipe.

Why This Recipe Works

To make this soup more keto-friendly with only 7 carbs per serving, mostly from the broccoli, I eliminated the carrots and flour all together. I added extra broccoli to compensate for the carrots, plenty of garlic, and a little shallot to add even more flavor.

This low carb version of broccoli cheddar soup uses mostly sharp white cheddar cheese with a little smoked gouda. It’s the perfect combination of cheesiness with a hint of smokiness.

This soup can be served as an appetizer, for lunch, or for dinner. It’s also perfect for meal prep. I like to divide it into meal prep containers and have a bowl for lunch during the week.

How to Make Keto Broccoli Cheese Soup

Ingredients

Ingredients needed to make keto broccoli cheese soup on a white background with labels

  • I use chicken stock or chicken bone broth, but you can use vegetable to stock to keep this recipe vegetarian. Just be sure to check the ingredients as some vegetable stocks have added sugars.
  • Shred the cheese from a block for the best results. Pre-shredded bagged cheeses contain added starch and can make your soup have a grainy texture.

The entire recipe and instructions can also be found in the recipe card at the bottom of this post. You can also print the recipe from the card, if needed.

Prep!

Either chop your broccoli into very small pieces with a knife, or toss it into a food processor and pulse just a few times for quicker results. The eliminates the need to use an immersion or stand-blender.

Shred the cheeses and mince the garlic and shallot.

    My husband has been following a keto diet, so I’m always looking for new inspiration on what to make for dinner. This soup looks wonderful, especially for a chilly winter night.

      It’s so hard to get back on track. I’ve done low carb most of the last 6-8 years, but this is my second attempt at keto…so far, so good!

      Thanks so much! The gouda definitely adds a smokiness to the soup – it’s different but really good!

    OHMYGOSH I just made broccoli cheese soup last night!! Too funny. I made a version with cashew cheese for me and a ‘normal’ version for my hubs. Still perfecting the normal version, but I feel like this one would be awesome because of the two different cheese varieties. He is going to love it!
