Sommer’s Recipe Notes
Why We Love This Chicken Mushroom Soup Recipe
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!)

Tips & Tricks
- 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!

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

Ingredients
- 2 tablespoons unsalted butter
- 1 large sweet onion, peeled and chopped
- 1 cup chopped celery
- 5-6 cloves garlic, peeled and minced
- 18 ounces sliced mushrooms, mixed varieties
- 1 teaspoon fresh chopped rosemary
- 1 teaspoon dried thyme
- 1/3 cup dry sherry
- 1 pound boneless chicken breast
- 8 cups chicken broth
- 2/3 cup heavy cream
- 1 tablespoon cornstarch (or arrowroot for ketogenic)
- 1/4 cup chopped parsley
- Salt and pepper
Instructions
- Add the butter to a large 6-8 quart soup pot and set over medium heat. Once melted add the onions, celery, and garlic.
- Sauté for 2-3 minutes, then add in the mushrooms, rosemary, and thyme. Sauté until the mushrooms soften and cook down.
- Deglaze the pot with dry sherry. Then add in the whole chicken breasts, chicken broth, 1 teaspoon salt, and 1/4 teaspoon black pepper. Bring to a boil. Then lower the heat and simmer for 15 minutes, or until the chicken breasts have cooked though.
- When the chicken is fully cooked, remove the breasts with tongs, and chop into bite-size pieces.
- Whisk the cornstarch into the heavy cream, making sure there are no clumps. Then whisk the heavy cream into the soup pot and allow it to simmer and thicken. Stir the chopped chicken back into the soup and add the parsley. Taste, then salt and pepper as needed.
This is some of the best soup I’ve ever had. I made it with fresh herbs, chicken thighs, and baby bella mushrooms. So delicious!
Finally found the perfect chicken mushroom soup after searching many sites, thanks for sharing this.
I made this in my Instant Pot. I pressure cooked the chicken breasts first, hoping to make this soup a little faster. Also, because I’m doing keto, I exchanged the corn starch for xanthan gum for thickening, but kept in the onion. I used a little less sherry than the recipe called for due to the alcohol and sugar content, but did keep it in the ingredients, just used less. It turned out delicious! Very pleased with the results!
Sounds perfect will try tomorrow
This was great, thank you! It’s hard for me to find a meal that all 6 family members will truly enjoy.
Great low-carb dish. Took much longer to prepare than the estimated time, but I’m a slow cooker (ha).
I am a cooking novice, so this took forever for me. I don’t think I could do this after a long day of work, for example. But being that it’s cold weather and I just hung some Xmas lights, I was in the mood for a pot of something warm and homey. And it turned out so great! Savory and flavorful. I didn’t modify the recipe.. just made it as described above.
My husband has been keto for almost a year. It was great to find a recipe that we both enjoyed. I only had cremini mushrooms but they worked very well. I had leftover chicken that also worked very well. No sherry in the liquor cabinet but we didn’t miss it. I sauteed the veggies in bacon fat (yummm!!) and added only 6 cups of home made chicken stock. Hubs had 2 bowls and pronounced himself ‘stuffed’. I could only manage one. Thanks for a great recipe. Definitely a keeper!
I usually leave out rosemary just because I often don’t have any on hand. I also always use the leaves from the celery because I like the flavor. I’ve made this as written and it’s amazing as it is. My tweaks are just based on what I have in my kitchen or my mood. This is a delicious soup that can easily be modified to fit your taste. Sometimes I add a little more heavy cream, sometimes I purée some to make it a cream soup, more mushrooms, bacon, or any number of tweaks make this a very versatile soup. You can’t lose with the original version, but it’s nice to change it up sometimes too.
I would leave out the added salt if you have to watch your salt intake. Other Than that I enjoyed it.
I am going to be making this all fall and winter! Yum!
The addition of sherry is fabulous. Such a flavour boost.
