If you’re looking for a hearty and filling soup, this one’s for you! I don’t know about you, but I sometimes feel like broccoli cheese soup is a bit lacking. It’s filling, but it doesn’t quite have enough staying power – so this recipe solves that problem by adding shredded chicken!

Tips for Making Keto Broccoli Cheddar Chicken Soup {Quick Overview}
These are just a few quick tips for making the cheddar low carb chicken soup. For the recipe in detail, scroll to the recipe card at the end of the post.
⭐ Tip 1: Use freshly shredded cheddar cheese. Pre-shredded cheese can make your soup clumpy because of the anti-caking agents, so it’s worth taking the extra step to shred it yourself.
⭐ Tip 2: Chop your broccoli to your liking. I’m a fan of bigger broccoli florets in my soup, but if you prefer smaller pieces, go for it! Smaller pieces cook faster, so you won’t need to leave the soup on as long in Step 4.
⭐ Tip 3: Want a thicker soup? Add xanthan gum. If you like your broccoli cheddar soup thick (like the kind served at restaurants), you can stir in xanthan gum as the recipe suggests. It’s an easy, carb-free way to thicken things up! (For reference, the soup in my photos doesn’t have xanthan gum—I like mine a bit more brothy.)
⭐ Tip 4: Reheat the soup slowly. Whether you’re using the stovetop on low or short bursts in the microwave, take it slow and stir often. This will help keep the cheese from separating and messing up that creamy texture.
