Pre-heat the pot on the stove. In the pot, place the onions, minced garlic, salt, and pepper. Sauté on medium until the onions are clear.

Sprinkle xanthan gum over the butter and onions. Stir in the chicken broth.

Put the broccoli in the pot. Ensure the vegetables are coated with broth mixture.

Quickly stir in the cream. Stir frequently so the xanthan gum mixes in and thickens. Bring the soup up to a boil, then reduce heat and simmer.

Once simmering, slowly begin whisking the cheese into the pot. If preferred, add additional chicken broth to achieve desired consistency.

Serve warm.
