I know there are already eleventy-billion keto broccoli cheese soup recipes out there, but since I make this one all the time, and it is not only easy but incredibly tasty and satisfying, I thought I’d share it with you anyway.

Before we get to this keto broccoli cheese soup recipe, I must tell you that I’ve recently been introduced to the joys of the parmesan cheese chip – and I’m hooked.
Ironically I was so outraged over paying $7 for a head of cauliflower that I wrote an irate letter and boycotted it (at least temporarily) due to the price – buuuuuuuttt when it comes to Parmesan (or Asiago YUM) cheese crisps that I could easily make at home for literally pennies???
I paid $4.99 for a 7 oz bag that had maybe 15 chips in it.
And I’d do it again.

Just look away OK, I can’t bear to see you witness my shame….
Parmesan cheese crisps (homemade or otherwise) are a super tasty crunchy addition to this keto broccoli cheddar soup. You can also set aside some smaller pieces of cooked broccoli to add to this low carb broccoli soup if you want a chunkier texture.

I wanted this keto broccoli cheese soup to be basic at its foundation – but you can easily throw in some chopped bacon, chicken or ham to make it even heartier if you prefer!
Full disclosure – I made this entire batch of keto broccoli cheddar soup in the microwave, so there is no stove required. I know some of you are gasping in horror because you think the microwave is the devil, but some people are living in dorm rooms where all they have is a microwave, and those people are psyched right now.
You can absolutely make this cheesy keto broccoli soup on the stovetop – just saying you don’t NEED to if it’s not an option or you’re pressed for time.

Finally, I used beef broth in this keto broccoli cheese soup recipe, which I think enhances the flavor of the broccoli and cheese more than chicken broth does. You can use chicken broth if you prefer it though.
Also, you will greatly increase the health benefits of this (or any) low carb broccoli soup by using homemade broth from actual bones instead of store-bought. If using a purchased broth, you can increase the health benefits by adding a few tablespoons of beef collagen powder to it, which will also make your soup slightly thicker.

Hi there!
I’ve am on week one and have really enjoyed the diet and recipes so far. Thank you for all of your hard work in putting this together.
I have a question regarding the broccoli in this recipe. In the shopping list for week one it says to buy 2.5 lbs of broccoli florets. The recipe calls for 4 cups of broccoli florets. If I measure out 4 cups then I don’t come near to 40 oz of broccoli florets. Am I doing something wrong?
Mellissa Sevigny says
Thanks for catching that, I updated the list to be more accurate!
Vivienne says
I don’t ever write reviews but this soup is delicious!! I didn’t add the butter and it’s still the tastiest soup I’ve enjoyed in a while. Will be making this one again. Thanks Mellissa.
Sarah says
This soup is absolutely the best broccoli cheddar soup ever!! Thank you so much for all of your recipes this is probably my 8th one to try and all have been a fantastic turn out! Followed it exactly as written I wouldn’t change a thing about this! :)
Mellissa Sevigny says
Thanks so much Sarah!
Susan McCarry says

Deanna says
This chilly winter deserves a yummy soup that is heart and body warming! Thanks!!

I’ve yet to try it, but that was really cool to include a viable cooking option of a microwave. Kudos to you!
rina says
This soup is fantastic, along with all your recipes, I love how it tastes so good but with low cal. and it’s healthy. Thank you so much.
Melissa G says
This soup was fantastic! Other than initially steaming the broccoli in the microwave, I made it entirely in my Vitamix! I was hesitant about using beef broth, but OMG will never go back to chicken; it was that sublime. The soup was hot, thick, frothy and steamy. I realized later that I’d forgotten to add the cream and butter. I made another batch with all ingredients and it too was wondeful! I am happy for the error in my initial batch as I have some friends and family who enjoy LC eating but don’t necessarily want so much fat. Such a home run and I didn’t need to turn on the stove. How great! Thanks, Melissa.
Mellissa Sevigny says
Maybe one of your ingredients was spoiled or something – I love this soup and make it all the time!
Sally Veliquette says
Have you tried freezing this soup? We are doing a 4 week road trip and hauling our 5th wheel. I’m looking for some soups to make ahead and freeze for a quick keto meal on the road. Thanks!
Mellissa Sevigny says
I haven’t tried it – should work though the cream might separate?
