Expert Tips
This recipe is already so very simple but here are a few more tips I do to make my life easier.
- Chopping Vegetables – I use a small food chopper or food processor to quickly and easily chop onions. If you do not have one of these, I highly recommend them.
- Cheese – Shred your own cheese instead of buying pre-shredded. The pre-shredded cheese kind does not as smoothly.
Serve with your Favorite Toppings
This is totally optional but I love a little extra cheese on top.
Some people also like to add a little cream cheese to the soup while cooking. Just use what you prefer in this Broccoli Cheddar soup.
I also like to add a little garlic. The onion and garlic blends so well together and smells divine in this low carb Broccoli Cheese soup. We also love to serve with Olive Garden Breadsticks Recipe to get every last drop of the soup.

Can you Make this Soup in a Slow Cooker?
You can certainly try this recipe in your crock pot instead of the stove top. We love to do this when we will be away all day or need to come home to dinner waiting.
Place all the ingredients except for the cheese and cream in a slow cooker. Cover and cook on low for 4 hours. Then stir in the heavy whipping cream and the cheese. Cover and cook on low for 30 minutes until the cheese is melted.
Keto broccoli cheese soup slow cooker recipe is so tasty and always a hit with everyone. Even the kids love it!
How to Make Smooth Broccoli Cheese Soup
You can use an immersion blender or stick blender if you prefer the broccoli to be more blended. We love the pieces of broccoli but I know some people prefer it all blended together.
If you do not have one of these, try using a potato masher. Either way you make this, it is the best comfort food!
How Do You Thicken this Soup?
You can use xanthan gum to thicken the soup. Just a little bit will really help this soup come together.
It makes it so thick and delicious.

I have a delicious Crock Pot Broccoli Cheese Soup that you can check out!
Looks very good! Crockpot directions?
This help thickens the soup and is Keto friendly. You can thicken it as well with a cornstarch slurry. Mix together 2 tablespoons cornstarch with 2 tablespoons cold water and then stir into the soup to thicken it.
Just a heads up…very salty. For me, no need for the teaspoon of salt. I used organic chicken stock which has much less sodium. No clue how to tame the salt in the future. BUT soup came out PERFECT, aside from the saltiness.
I don’t have Xanthan Gum. Is this absolutely necessary or is there a substitute?
Annette – It’s difficult to put an exact size on the serving as each batch is different. The entire recipe makes 8 serving so 1 serving is approximately 1/8 of the recipe. I hope you enjoy it!
You told us the calories etc per serving but not how big a serving is. Please advise as I’m on keto and need to track it. I’m making this for dinner tonight.
Thanks, Annette
Oh no! I’m thinking that the cheese might have gotten overheated. That’s the only reason that it would not melt if using freshly shredded cheese and adding it in slowly.
My cheese didnt melt just kind of clumped at the bottome. What did I do wrong. I added it slowely. I also shredded my own.
This soup is soo good!! Thank you for sharing this recipe!
I would add it at the end.
If I make this in the crockpot like your other broccoli and cheese soup recipe, do I add the xantham gum in the beginning like the cornstarch or at the end like this recipe? Any other special introductions for adapting it to the crockpot? Can’t wait to make it! I’m using it for a mini cleanse to get back into ketosis. TIA
This is just easy and fabulous! Make it at least twice a month!
Delicious soup! Thank you for sharing.
Flavor is terrific. I had to double the Xanthan gum to get it to thicken but I bet when I cool and reheat it’ll help. Very very delicious.
Absolutely amazing! Better than Panera! Thank you!
This soup was amazing! I didn’t even need the Xantham gum for thickening., it was perfect on its own! So I am making it again in days!
Thank you Brandy!
This is so yummy!!!
