Ingredients

For the soup base

2 tablespoons unsalted butter
1 tablespoon olive oil
1 1/2 pounds boneless skinless chicken breasts cut into small bite-size pieces
8 ounces cremini or white button mushrooms sliced
1/2 cup yellow onion finely diced
3 cloves garlic minced
4 cups chicken broth preferably low sodium
1 cup heavy whipping cream
4 ounces cream cheese cut into small cubes and softened
1/2 teaspoon xanthan gum optional, for extra thickening
1 teaspoon fine sea salt or to taste
1/2 teaspoon black pepper freshly ground, or to taste
1 teaspoon dried thyme
1/2 teaspoon dried parsley

For finishing and serving

1/4 cup grated Parmesan cheese optional, for extra richness
2 tablespoons fresh parsley chopped, for garnish

Instructions

Heat the butter and olive oil in a large soup pot over medium heat until the butter is melted and foamy.
Add the chicken pieces in a single layer and cook, stirring occasionally, until lightly browned on the outside and just cooked through, then transfer the chicken to a plate and set aside.
Add the sliced mushrooms to the pot and cook over medium heat, stirring occasionally, until they release their moisture and become deeply browned and fragrant.
Stir in the diced onion and cook until the onion is softened and translucent, then add the minced garlic and cook until fragrant.
Pour in the chicken broth, scraping up any browned bits from the bottom of the pot, and return the browned chicken and any accumulated juices to the pot.
Stir in the salt, black pepper, dried thyme, and dried parsley, bring the soup just to a gentle boil, then reduce the heat and let it simmer for several minutes to allow the flavors to meld.
Reduce the heat to low and add the cream cheese cubes a few at a time, whisking or stirring constantly until the cream cheese is completely melted and smoothly incorporated into the broth.
Slowly pour in the heavy whipping cream while stirring, keeping the heat low and allowing the soup to gently heat through without boiling so the dairy stays silky and smooth.
If you prefer a thicker soup, sprinkle the xanthan gum lightly over the surface while whisking vigorously, then let the soup simmer gently for a few more minutes until it thickens to your liking.
Taste the soup and adjust the seasoning with additional salt and pepper if needed, then stir in the grated Parmesan cheese until melted for extra richness if using.
Ladle the hot soup into bowls, top with chopped fresh parsley, and serve immediately while warm and creamy.

Notes

For deeper flavor you can substitute boneless skinless chicken thighs for the breasts or use a mix of both. To keep carbs low, avoid adding flour, starches, or high carb vegetables such as potatoes or carrots, and rely on the cream cheese and optional xanthan gum for thickening. This soup reheats well on low heat, but avoid boiling after adding dairy to prevent separation. Leftovers can be stored in an airtight container in the refrigerator for up to 4 days or frozen in individual portions for convenient keto-friendly meals.
