Broccoli Cheese Soup Recipe

When it comes to keto soup recipes, my favorites include chicken soup, taco soup, and this broccoli cheese soup.

During my college years, one of my favorite takeout foods was Panera bread. While their sandwiches and salads were never anything to brag about, their soups, especially their broccoli cheddar soup, were something else.

Their broccoli cheddar soup (in the bread bowl, obviously) was something I enjoyed on a regular basis, so much that my local Panera bread knew me on a first-name basis. Since starting a keto diet, I’ve tried making a homemade version and I must admit… it tastes even BETTER than the original!

This keto broccoli cheese soup recipe comes together in under 20 minutes and is all made on the stovetop. It’s made with just 5 main ingredients (spices don’t count!) and is perfectly thick and creamy. It’s full of tender broccoli pieces and full of cheesy flavor, and is the kind of soup that sticks to your ribs!

What I love about this delicious soup is that even those who don’t follow a low carb diet will fall in love with it- It’s just THAT good!

Ingredients you’ll need to make this recipe

keto broccoli cheese soup ingredients
  • Butter– Unsalted butter to sautee the onions and garlic in.
  • Onion and garlic– Both these vegetables add extra flavor to the soup.
  • Chicken broth– Also known as chicken stock. You can use a homemade chicken broth or store bought. I like using organic chicken stock as it has no additives or added sugar.
  • Heavy cream– Gives the soup an extra rich and creamy texture, without affecting the flavor.
  • Broccoli– Finely chopped broccoli. Avoid using frozen broccoli as it will yield a much more thinner soup.
  • Smoked paprika– Adds some smokey flavor which works very well with the cheese.
  • Salt and pepper– To taste.
  • Cheddar cheese– A flavorful and easy melting cheese. You can swap out half of it with red Leicester or vintage cheddar if you’d like a more intense cheese flavor. Try to shred your own cheese, as it is cheaper to do and melts into the soup seamlessly.

How do you make keto broccoli and cheese soup?

Start by adding the butter into a deep saucepan and placing it over medium heat. Once melted, add the onions and garlic and saute for several minutes, until fragrant. Add the chicken broth, heavy cream, broccoli, smoked paprika, salt, and pepper, and bring to a boil.

Now, once the soup starts boiling, reduce it to a low and let it simmer for 20 minutes. After this time, add the cheese, half a cup at a time, until fully immersed in the soup. Remove it from the heat and serve immediately.

Pro tips to make the best broccoli cheddar soup

  • Be sure to chop your broccoli into fine, bite-sized pieces. This will ensure they cook evenly and are that there are no large florets throughout.
  • To prevent a grainy soup, be sure to slowly add the cheese into the saucepan, not all at the same time.
  • For a creamier soup, shred your own cheese. It will mix into the soup so much easier and taste that much better!

Frequently Asked Questions

Can I use a slow cooker?

Yes, you can make this soup in a slow cooker. Simply omit the butter and add all the ingredients, except for the cheese into a slow cooker. Cook on low for 6 hours. After 6 hours, slowly add the cheese and cover the pot and cook for a further 30 minutes.

What cheese is best for broccoli cheese soup?

Cheddar cheese is preferred, but you can use any flavorful cheese, like Colby, Tillamook, and Gouda.

Can I make a healthy broccoli cheese soup?

For a healthy broccoli cheddar soup, replace the heavy cream with light cooking cream and replace half the cheddar cheese with reduced-fat (25%) cheddar cheese. Do not use non-fat or low-fat cheese or else it will leave your soup grainy and clumpy.

Can I puree this soup?

This soup is designed to have chunks of broccoli throughout but if you prefer a silky smooth soup, you can either puree it (using a hand mixer) or in a blender.

Thicken the soup by adding 1/2 teaspoon of xanthan gum or 1-2 tablespoons of arrowroot powder. The arrowroot will add some extra carbs to the overall carb count.

    This is delicious and so easy. My crew (kids included) loved it AND it’s Keto friendly!! Thank you!!! I made some easy keto cheddar biscuits to go with this.

  2. Extremely delicious recipe. I had to make it a second time immediately after the first because I wanted more!

    The only thing that needs adjusting is the time estimates. Finely chopping 4 cups of broccoli, half an onion, and garlic is simply not possible to do in 2 minutes. Ten is probably more reasonable.

  3. 5 stars
    Ok, so I usually never leave comments. But OH CRAP. I just made this, with a few mods from what I didnt have (more butter, milk since no cream & added some shaved parm & had no paprika), but let me tell you. This is the most amazing soup. Its already saved in my pinterest to make again. I messed up and added the cheese and it got curdled, so I threw the soup in 2 batches into my vitamix (with the lid cracked for steam vent) and blended it smooth. SOOOO GOOOD!!! Make this asap

  4. 5 stars
    A very easy recipe to make this tasty rich soup. Definitely a recipe I will use often, whenever a tasty comfort food is desired.

  5. 5 stars
    Delicious! I added 4 oz cream cheese for thickening and a dash of red pepper flakes for an extra flavor layer. This is a keeper!

  6. This was an amazing recipe! It was creamy and delicious. I am definitely adding this to my cooking repertoire.

  7. Hi! This is soooo delicious! We love it! Wondering if frozen broccoli would work as well as fresh?
    Thanks again!!
