How to Make the Soup

Simple instructions on how to make cream of mushroom soup.

Allow mushroom soup to cook on low for 15 minutes until it reaches the desired consistency.

  3. Add broth, sugar, sherry
  4. Pour in heavy cream and allow to cook on simmer for 15 minutes (if you want thicker, add slurry)
  5. Garnish with fresh thyme and serve

How to Clean Mushrooms

Because mushrooms are like little sponges, don't rinse them but use a damp paper towel and wipe away any dirt or debris. If you rinse the mushrooms, they'll be water-logged and flavorless.

How to Make a Thickening Slurry

In a one-cup measuring cup, add 2 tablespoons of either flour or cornstarch; fill measuring cup with warm water; combine well and add to soup after you've added the heavy cream

Nutritional Benefits

Mushrooms have been a staple in the diet since ancient times. They are neither fruit nor vegetable, but a fungus. They are self-sufficient in nutritional development because they gain their nutrients from metabolizing non-living organic matter.They're also the perfect food due to their naturally low sodium levels, zero fat and cholesterol, and lack of gluten.
White button mushrooms are the most popular because of their mild flavor. These young mushrooms are found in salads, pizza toppings and mushroom sauce. Shiitake mushrooms are on the opposite end of the spectrum of white buttons. They are aged, offer a deep woodsy flavor and are more firm. You'll often find Shitake mushrooms as a meat substitute in vegetarian dishes.
Cremini are small brown mushrooms, often referred to as "baby bellas" and offer a deeper flavor than button mushrooms; they are also a bit firmer than a button mushroom and usually accompany a pork or beef dish. Many Asian dishes use Cremini mushrooms.
For many, it’s a habit to check the fat, protein carbohydrate and vitamin contents of a food, but we rarely check the trace mineral values of a food. Trace minerals are required for our bodies in maintaining healthy fluid balances, regulating hormones, regulating blood pressure and more.
