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 homemade Broccoli & Cheese Soup again. 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 my Broccoli & Cheese Soup 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! If you don’t have an Instant Pot there are several different models and sizes. You can check them out here.
If you don’t have an Instant Pot my original Broccoli & Cheese Soup Recipe is cooked on the stove top.

Can you use fresh broccoli instead of frozen? And how much if so?
Sure. I’d say the same amount but perhaps increase the cook time for a minute or so. I’ve only tested frozen broccoli.
How can I do this in the crockpot?
How much is a serving….1 cup?
I would say yes.
Just made this and I am eating is right now! WOW! I love it! Thank you for a great recipe!!
You are so very welcome! Glad that you enjoyed it!
Looks delicious! Do you have the net carb count on each serving?
That information is at the very bottom of the recipe box. Thanks!
By far one of the best soups I’ve ever made. And even better that it is keto!!
I’m so glad you loved it.
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
I’m not sure. I have only used Xanthan Gum as a thickener since it is keto approved.
Would it taste ok with veggie stock? I do not eat any meat
I’ve only tried it as is, but it is worth a try. I would think it would be fine.
Is bone broth ok to use?? Thank you.
I’ve only made it as is, but it is worth a try with bone broth.
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
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.
I just made this and I added bacon. It’s amazing!! Thank you.
Awesome! Bacon is so good in Broccoli & Cheese Soup!
