Homemade Cream of Mushroom Soup Recipe

This homemade cream of mushroom soup is worlds above any canned version. Rich, flavorful and creamy soup with a buttery and umami flavor thanks to the sautéed mushrooms and onions that form the flavor backbone of this recipe.

You can customize the texture of this recipe to your personal preferences:

• Like a lightly creamy soup with no bits of veggies mixed in? Sauté the veggies to extract their flavor and then remove and save them for another recipe or to be enjoyed on their own.
• Do you like the light texture of canned soup and want chunks of soft, perfectly cooked veggies? Add the veggies back in after the broth has been added
• Or, for a thick soup that sticks to the spoon, puree the veggies with a bit of the soup (or additional broth) and stir them back into the pot

This cream of mushroom soup is not just a rich and creamy bowl of soup that can be enjoyed on it’s own – it’s actually a great recipe to replace store-bought cream of mushroom in your favorite casserole recipes.

For example, I use this homemade cream of mushroom soup for our Green Bean Casserole. I think it tastes way better than making it with canned soup, partially due to severely reducing the amount of salt that we’re using, and I feel better about serving one less meal with processed foods to my family. (Not that I’m perfect about that – but every effort counts.)

This homemade cream of mushroom soup comes with a bevy of health benefits including providing your body with iron, vitamin D and selenium, which is an antioxidant that benefits your immune system and heart health.

How do you thicken cream of mushroom soup? There are a few ways to thicken cream of mushroom soup but in this recipe we use melted butter and flour to form a “roux” that serves to thicken the soup and impart flavor.

If desired, you can use heavy whipping cream to thicken your soup or swap out the flour for cornstarch. To use heavy whipping cream, replace the milk called for in this recipe with heavy whipping cream and allow the soup to come to a boil before simmering until thickened.

Can cream of mushroom soup be frozen? Some people have had success with freezing this recipe, but I personally avoid freezing soups with any dairy in them as the dairy can separate from the rest of the soup and take on an unappetizing appearance.

Storage: this recipe can be kept in an airtight container in the fridge for up to a week with no change in flavor or texture.

How to Make Cream of Mushroom Soup

In a medium-sized saucepan, melt 1 Tablespoon of the butter.

Add the mushrooms and onions to the hot butter and sautee until onions are translucent, about 3 minutes.

Add garlic and continue cooking for 1 minute.

Remove vegetables to a small bowl and then add remaining 2 Tablespoons of butter to the saucepan. (The reserved onions and mushrooms can be added back to the soup later or saved as a separate side dish.)

Use a spatula to scrape up all the browned bits in the saucepan.

Once the butter is melted, whisk in your flour to form a roux.

Whisk 1 cup of the milk into the roux to make a thicker paste, then slowly whisk in the broth.

Add the second cup of milk if planning to use as a soup – if using in casseroles, you may want to omit the second cup or not add the full cup.

Once warmed through, remove from heat.

If desired, add back in the reserved onions and mushrooms. To make a thicker soup, you can puree the mushrooms and onions with a bit of broth and stir back into the soup mixture.

Makes 5 cups.
