Healthy Cream of Mushroom

One of the best things about this soup (besides its amazing taste) is that it is healthy!! There are no chemicals or unnatural ingredients to be found. Yep. All ingredients are pronounceable!

🥘 What You'll Need

Here are the ingredients you will need to make this soup:

Ingredients

  • Butter
  • Onion
  • Mushrooms
  • Parsley
  • Heavy Cream
  • Salt
  • Pepper

Additional ingredients if making cream of soup from the condensed version:

  • Milk (Use nonfat or 2% . You can use whole milk but it will very rich).
  • Xanthan Gum mixed with 1 tsp olive oil

Note: xanthan gum is a low carb thickener. Dissolving it in a fat such as olive oil keeps it from clumping when added to your soup. A little goes a long way, start with 1/2 tsp up to 1 tsp. 

For exact ingredient quantities, please see the recipe card below!

How To Make Condensed Cream of Mushroom Soup

Over medium heat, melt butter in a skillet and sauté onions and mushrooms until very tender. Add parsley then stir. Reduce heat to low, stir in cream, salt, and pepper.

Stir frequently, continue simmering soup until liquid is reduced by more than half and very thick. You should end up with approximately 12 oz of condensed soup. Remove from heat and allow to cool.

Place in an airtight container. Store in the refrigerator for up to three days or the freezer up to three months. Allow soup to come to room temperature before using.

💭 Top Tips

    I used 1 tsp of salt
    1/2 tsp of pepper
    1 Tbsp parsley

    I think 3 tsp of salt as recipe recommended is way to much

      I made that mistake. I thought about it before I did it, but did it anyway. I ended up adding another cup and a half of heavy cream. It was still salty, but usable in the stroganoff recipe. Just thought I would warn others. Otherwise, delicious!

    It making a Keto version, would you substitute the milk with heavy whipping cream, almond milk, or a combo of both?

      You could definitely substitute. I usually use heavy whipping cream and/or half and half.

      Hi Kelly! Thank you, I am so glad you love it. 🙂 I make batches of it and use it all the time. So good. Is it a social share button link that is not working?

Hey there, I'm Kori.

I’m a culinary school trained chef specializing in holistic nutrition and wellness. I’ve always been a major foodie, and as I’ve aged, the full impact of my love of food—and not-necessarily-healthy eating habits—caught up to me. In an effort to make positive changes in my life (and hopefully yours, too), I created this website where I could share great-tasting, craveable, healthy recipes.
