Dice up the broccoli into bite size pieces. You want them very small. Set it aside.
Meanwhile in a stock pot, add butter, onion, celery, salt and pepper. Cook over medium heat until the onions are translucent.
Add the broccoli and continue to cook for 3-4 minutes until the broccoli turns bright green and is soft.
Add in the chicken broth and heavy whipping cream. Stir.
Bring to a boil. Once boiling turn down the heat to simmer and slowly add the cheese, mixing as you add.
Melt cheese and add in the xanthan gum and remove from medium heat.
Stir until soup thickens.
Serve warm and enjoy!
