    Few foods are comforting like a warm bowl of soup. I like to prepare this Keto Broccoli Cheese Soup recipe on the weekend to have on hand for an energizing meal throughout the week. It is cheesy, creamy, and so satisfying.

    Soup is always a comforting meal, and I'm not sure it gets any better than this broccoli soup. 


    It is cheesy and filling, making it the perfect addition to your low-carb diet.
    Give it a try, and I know you will love it as much as I do!

    Thickening Broccoli Cheddar Soup Naturally

    This Keto Broccoli Cheese Soup recipe is so rich and so creamy. 


    The secret? The addition of cream cheese increases the decadence factor and helps create a thick soup without needing any additional thickeners. 


    This is a great way to keep your broccoli soup keto in a way that doesn't require ingredients that you probably don't already have in your pantry and fridge. 


    I think you will agree that this keto-fied soup is so much better than the original.

    Ingredients for Making Low Carb Broccoli Cheese Soup

    Overhead photo of broccoli, celeery, butter, onion, garlic, broth, cream, vinegar, cream cheese, seasonings, and cheddar cheese.
    • Butter: I recommend using unsalted butter.
    • Onion: Either yellow or white onion will work in this recipe. Red onion will work, but it will impact the overall color when you blend the soup.
    • Celery: If you don't have celery, you can use celery salt in place of the salt.
    • Garlic: You can use ½ teaspoon of garlic powder in place of the broccoli.
    • Broccoli: I prefer fresh broccoli, but frozen broccoli florets may also be used.
    • Broth: For the fullest flavor in this keto broccoli soup, I recommend using homemade broth. I make my Instant Pot Chicken Bone Broth at least once a week. If you are short on time, purchased chicken broth works just fine.
    • Cream Cheese: Make sure you use full fat.
    • Seasonings: Smoked paprika, salt, and pepper add just the right amount of flavor.
    • Heavy Cream: If you are not keto, you could use half and half if you prefer.
    • Cheese: I used all cheddar in this keto cheese soup, but you can mix it up if you like. Gruyere, mozzarella, and havarti would work as well.
    • Vinegar: While it may seem like an odd ingredient, vinegar adds just a touch of acid that I love. Lemon juice would be a great substitution.

    Variations

    • Add 1 tablespoon of hot sauce or ¼ teaspoon cayenne pepper for an extra kick.
    • To brighten the soup, finish with a squeeze of fresh lemon juice.
    • Substitute cauliflower for half of the broccoli.
    • Use smoked gouda or gruyere cheese for half of the cheddar.
    • If you prefer a thicker soup, add in ½ teaspoon xanthan gum.

    Serving Suggestions

    • A side salad with a vinegar-based dressing
    • Keto-friendly bread
    • Steak or grilled chicken
    • A chaffle

    Toppings for Keto Broccoli Cheese Soup

    Frequently Asked Questions

    Can I have broccoli on the keto diet?


    Absolutely! Broccoli is an excellent addition to any low-carb or keto diet.

    One cup of chopped broccoli has 3.34 grams of net carbs, making it a great way to add some green to your plate and keep your carb count down. (Source)

    Is Broccoli and Cheese Soup Keto-Friendly? How many carbs does Broccoli Cheese Soup have?


    In most cases, no, because the carbs in broccoli cheddar soup are too high for a keto diet.


    As an example, Panera's Broccoli Cheese Soup has 19g carbs per cup, and Campbell's has 16g carbs. 


    Even most homemade recipes are thickened with flour, which makes them a no-go for a ketogenic diet. 


    This homemade Keto Cream of Broccoli Soup is perfect for your keto diet, though! With just four net carbs a serving, this is one you can make again and again with no guilt.

    How Do I Make Keto Broccoli Cheese Soup Thicker?


    There are several ways to make your soup thicker. In this recipe, I've used cream cheese, cheese, and pureed broccoli to thicken the soup. I have found that this makes it thick enough. 


    If you prefer a thicker soup, feel free to add in ¼ to ½ teaspoon of xanthan gum. Make sure you go slow because a little goes a long way - this low-carb broccoli cheese soup recipe can get too thick quickly if you use too much.

    Can I Use Frozen Broccoli in This Recipe?


    Yes! It works fine. Just make sure that you thaw it and drain any excess water.

    Can You Buy Keto Broccoli Cheese Soup?


    The only keto-friendly brand that I have found is Kettle u0026 Fire. It is tough to find in stores, but you can get it from Amazon. 

    I have tried it, and while it isn't as good as homemade, it is tasty,, and I try to keep it in my pantry at all times. It has saved me when the fridge and freezer are bare, and the only thing I am seeing is my kids' snacks.

    Can I Freeze This Recipe?

    Stir in the vinegar and season to taste with salt and pepper.

        Most savory recipes benefits from a touch of acid - just for a little flavor pop. Lemon juice would work well too - or you can leave it off entirely.
