Keto/ low Carb/Gluten Free Mushroom Soup

If I had to list some of my favorite things about fall, soup would be one of them. I mean, fall foods, in general, are my favorites, but soup is definitely the top one on my list. Super rich, savory and satisfying… this easy keto/ low carb cream of mushroom soup is pure comfort in a bowl! My recipe calls for a couple pounds of cremini and white button mushrooms. Don’t have both? Either will do, though I love cremini (young portobello mushrooms) because they are a little tastier and add a deeper flavor to this soup.

So if you love mushrooms (like I do) you are going to LOVE this soup.  It’s chock-full of fresh mushrooms in a rich, savory and creamy broth.  The best part is that it’s ready in under 40 minutes and you can customize it to your preference.

  • Add shredded rotisserie chicken for extra protein.
  • For a richer soup, swap the chicken broth, for beef stock or bone broth.
  • For a lighter soup (or a vegetarian version), swap the chicken broth for vegetable broth.
  • For a dairy-free version, omit the cream cheese and swap the heavy cream with coconut milk
  • Top it with bacon bits for epic deliciousness.

    I made this recipe over the weekend for my family and it was delicious! I only did 1.5 pounds of sliced mushrooms because I thought I had so many as I added it to the pot- I was wrong – they cooked down quite a bit. I will definitely use the full 2 pounds for next time. The consistency and flavor was spot on. My family loved it, even the little kids enjoyed it, which is always a win in my house! Thank you Mona for always trying to make recipes as close to “normal” food as possible. I enjoy your recipes and appreciate that it’s not just pork rinds dipped in bacon grease – that’s not how I keto! Thanks for a great recipe!

    1. Aww you really made me smile. Thank you so much for trying my recipes and I am so glad that you and your family enjoyed the soup. You can never have enough mushrooms 😊

  3. I’d like to use this in a recipe that calls for cream of mushroom soup in a slow cooker. Would this substitute well?
