Chicken Mushroom Soup

When you think of autumn flavors, what comes to mind? Apples? Pumpkins?

To me, mushrooms are the purest flavor of fall.

Recipes that are mushroom-heavy offer an intense rustic depth that cannot be replicated by any other ingredient.

In fact, quite often when I taste a dish and feel like it’s missing something, it’s that underlying umami essence we find so abundantly in mushrooms.

Today’s recipe, Chicken Mushroom Soup, is chock-full of umami goodness and is LOW CARB!

It’s creamy, chunky, robust, and subtle… All in the same bowl.

Plus, it’s packed with protein and very low in carbs. (You can even make a ketogenic version with just a couple of small tweaks!)

How To Make Mushroom Soup With Chicken

  1. Start by placing the butter in the soup pot and then add the onions, celery, and garlic. Saute for 2 to 3 minutes.
  2. Add the mushrooms to the mixture, along with the rosemary and thyme. After sautéing the mushrooms, deglaze the pot with dry sherry.
  3. Add in the whole chicken breasts, the chicken broth, salt and pepper. Then simmer them in the broth. Wait until the chicken is fully cooked then take it out and chop into bite-sized pieces. 
  4. Add the cornstarch to the cream and whisk until there are no clumps. A generous splash of heavy cream gives the mushroom and chicken soup a luxurious finish.
  5. Then add in the chopped chicken and parsley. Season to taste.

Soup Cooking Tips

  • When I make chicken soup, I like to poach whole chicken breasts right in the broth. This not only gives the chicken broth a richer flavor, but it also protects the chicken from overcooking.
  • Cooked chicken is easier to cut into chunks than raw chicken. So you simply pull the cooked breasts out of the soup with tongs. Chop up the pieces. Then throw the chicken chunks back into the mushroom and chicken soup.
  • The cream provides enough fat to balance the Low Carb Creamy Chicken Mushroom Soup’s macros so it’s perfect for a ketogenic diet.
  • Although this Low Carb Chicken Mushroom Soup recipe is not dairy-free, it still tastes delightful if you leave the dairy out. Of course, the broth is then thinner, and the soup is no longer “ketogenic.” Yet it is still low carb, high protein, and tantalizing to the tastebuds!

Serving Suggestions

This healthy mushroom chicken soup is wonderful on its own, but you can also serve it with some lovely side dishes to create a more hearty meal! Keep in mind, some of these options are not low carb, but some of them are! Here are some of my favorites:

Frequently Asked Questions

What does “deglaze” mean?

Deglazing means to pour liquid into a pan and let the simmering liquid help to loosen and lift the crusty particles on the bottom of the pan. You usually move the contents around with a wooden spoon to help the process along. This not only keeps the particles on the bottom of the pan from burning, but it also intensifies the flavor soup.

Can this be made in a crockpot?

Yes, absolutely! Just be sure to sauté all the vegetables on the stovetop before placing them in the slow cooker. Slow cook on low for 4-6 hours. Then add the cream mixture and slow cook another 30-60 minutes to thicken. In the end, you will have a super creamy homemade chicken mushroom soup!

What can I use instead of sherry? 

The sherry does a LOT for the flavor of this soup. It is the perfect complement to mushrooms. However, it is not absolutely necessary. You can find small bottles of cooking sherry at the grocery store. If you want to take it out, add in extra broth instead. 

Can this soup be frozen?

Yes. It freezes well and will last in the freezer for up to 6 months. Just make sure to rewarm the soup at room temperature before reheating, then heat on medium-low so the cream doesn’t separate.

How long does it keep in the fridge?

This soup can keep in an airtight container in the fridge for 4 to 6 days.
