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!

    My first InstantPot Keto recipe! Super easy cheesy deliciousness! Thanks so much for taking time to post these free recipes🙋‍♀️👍

    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!

    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!

    This is the most delicious broccoli soup I’ve ever tasted. My husband overcooked broccoli the previous night for dinner and so the next day I made this soup. I used a regular pot on the stove.
    The next morning I added 2 TBSP of this soup on top of my sausage and scrambled egg breakfast. So very delicious!!

    1. It would prob need to be ajusted but I can’t remember making it with fresh broccoli to give you an exact time.
