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!

    1. Sure. I’d say the same amount but perhaps increase the cook time for a minute or so. I’ve only tested frozen broccoli.

  1. 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

    1. I’m not sure. I have only used Xanthan Gum as a thickener since it is keto approved.

  2. 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

    1. 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.

    1. Great! I think it is great to customize a recipe to make it more suitable to your liking. Glad you enjoyed it.

  3. 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 !!!

    1. 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.
