How to Make Low Carb Creamy Chicken Mushroom Soup Recipe

Step 1: Sauté the Aromatics and Mushrooms

Start by melting the butter in a large soup pot over medium heat. Toss in the chopped sweet onion, celery, and minced garlic, stirring until they begin to soften and release their savory aroma, about 2 to 3 minutes. Next, add the sliced mushrooms along with fresh rosemary and dried thyme. Cook until the mushrooms have released their moisture and are tender, giving the soup its signature earthy richness.

Step 2: Deglaze and Simmer the Chicken

Pour in the dry sherry to deglaze the pot, scraping up any bits stuck to the bottom—that’s pure flavor waiting to infuse your broth. Place whole boneless chicken breasts into the pot, then add chicken broth along with salt and pepper. Bring everything to a boil, then reduce to a gentle simmer for about 15 minutes until the chicken is fully cooked through and tender.

Step 3: Chop Chicken and Thicken the Soup

Remove the chicken breasts with tongs and chop them into bite-sized pieces for easy spooning later. In a small bowl, whisk together the cornstarch and heavy cream until smooth and lump-free. Slowly pour this mixture into the soup, stirring continuously as it simmers and thickens slightly, creating that creamy luxurious texture we love.

Step 4: Final Touches and Seasoning

Return the chopped chicken to the pot, stir in fresh parsley for a pop of color and brightness, then taste and adjust seasoning with additional salt and pepper if needed. Your creamy, comforting Low Carb Creamy Chicken Mushroom Soup Recipe is now ready to warm your soul.

Freezing

FAQs

Can I make this soup dairy-free?

Using a mix of mushrooms, like cremini, shiitake, and button mushrooms, adds complex layers of flavor. Feel free to use whatever varieties you prefer or have on hand for a unique touch.
