Instant Pot Keto Broccoli Cheese Soup Recipe
One of the very first meals I cooked when I started following a ketogenic/low carb lifestyle was Broccoli & Cheese Soup. I had avoided it for years due to the high-fat content. Now that I was eating high-fat foods with Keto, I couldn’t wait to start enjoying keto broccoli cheese soup.
As a busy homeschooling momma, I try to keep things simple. One way I do this, especially when the weather is cold, is by making a big pot of soup to eat for lunch all week. This Keto Broccoli Cheese Soup is on my menu at least twice a month because we all love it.
Last night I decided to tweak the recipe so I could make it in my Instant Pot. I just love my Instant Pot. It’s kind of like a Crock-Pot on steroids as it cooks so much faster. It also infuses the food with flavor making it taste as if it has been simmered on the stove for hours. No wonder the Instant Pot has become so popular!

Karen says
Can you use fresh broccoli instead of frozen? And how much if so?
Kasey says
Sure. I’d say the same amount but perhaps increase the cook time for a minute or so. I’ve only tested frozen broccoli.
Kristy says
How can I do this in the crockpot?
Jennifer says
How much is a serving….1 cup?
Kasey says
I would say yes.
Charlene says
Just made this and I am eating is right now! WOW! I love it! Thank you for a great recipe!!
Kasey says
You are so very welcome! Glad that you enjoyed it!
D. Milano says
Looks delicious! Do you have the net carb count on each serving?
Kasey says
That information is at the very bottom of the recipe box. Thanks!
Amanda says
By far one of the best soups I’ve ever made. And even better that it is keto!!
Kasey says
I’m so glad you loved it.
Dolores says
Hi ~ Don’t have Xanthan Gum. What can I use in the pressure cooker that’s ok and won’t increase carbs. I need to keep them low.
Thanks. Dolores
Kasey says
I’m not sure. I have only used Xanthan Gum as a thickener since it is keto approved.
patti says
Would it taste ok with veggie stock? I do not eat any meat
Kasey says
I’ve only tried it as is, but it is worth a try. I would think it would be fine.
Beckie says
Is bone broth ok to use?? Thank you.
Kasey says
I’ve only made it as is, but it is worth a try with bone broth.
Maryanne says
I’m having a big family dinner and want to make this amazing soup ahead of time. Do you think it would hold up to warm setting in a slowcooker for an hour or two ?
Thank you
Kasey says
I am not sure I haven’t personally tested to do that. Sometimes, if the temp is too hot the dairy products begin to break down and become grainy, but if the temp is only on warm perhaps that won’t happen.
Lauren gardner says
I just made this and I added bacon. It’s amazing!! Thank you.
Kasey says
Awesome! Bacon is so good in Broccoli & Cheese Soup!
Iona says
I would cut cheese in half, toooo cheesey. I used fresh broccoli. Good soup!
Kasey says
Great! I think it is great to customize a recipe to make it more suitable to your liking. Glad you enjoyed it.
Brittany says
We loved it, didnt like how big the frozen broccoli florets were so we used the emulsifier. I dont why but the xantum gum didnt thicken thou. I just love all your recipes that ive made so far !!!
Kasey says
I’m so glad you loved it. It is always great to customize a recipe to your liking like you did with the emulsifier. Xanthan Gum has to have time to sit on the recipe to thicken the sauce.
Jeremy Bunn says
Amazing, loved it. So much better than premade.
Kasey says
Awesome! So glad you loved it!
Mary says
High or low pressure?
Hortensia R Acosta says
First time making the soup and it was easy. Yummy!
Kasey says
Awesome! Glad you enjoyed!
MICHAEL B says
Have you ever added bacon? If so, how long should I saute it?
Kasey says
My family usually sprinkles crispy bacon pieces on top of the soup.
Lindsay says
I just made the recipe tonight. It was a hit with the whole family. Thank you for a yummy recipe!
Kasey says
So glad you enjoyed!!
Louise says
Do you think chicken bone broth would work
Instead
Kasey says
I have only tried it as is. May work though. Let me know how it turns out.
Sue says
How many carbs are in the soup and what is the size of a serving?
Kasey says
Hey Sue, the nutritional info is on the recipe card.
Molly says
Quite good! I would do more onion and garlic.
Kasey says
So glad you liked it!
Rebecca says
My first InstantPot Keto recipe! Super easy cheesy deliciousness! Thanks so much for taking time to post these free recipes🙋♀️👍
.Kasey says
You’re welcome, Rebecca! I’m glad you enjoyed your first InstantPot Keto recipe.
CrackerJack says
Wow, I’m really impressed with this recipe. There are tons of versions of broccoli cheddar soup online but I just made this one for dinner because it had the most reasonable carb count. Making it paid off in a big way.
I verified the carb count too as I went and my version came out almost exactly. Also, I was surprised at how well the nutmeg worked in the soup!
As a tip I mashed the broccoli with a potato masher a couple times (very few, I like chunks) to get the perfect size of florets.
Thanks for posting, I really appreciate it!
.Kasey says
You’re so welcome! I’m glad you enjoyed the soup!
Audra says
This is DELICIOUS!!! My cheese didn’t melt all the way though… any thoughts?! I shredded it and added it slowly. It’s still not completely melted. It’s very tasty, but weird. LOL HELP!
Kasey says
Glad you enjoyed it. I am not sure without being there to watch you make it.
