Who doesn’t love soups? A good bowl of soup can be eaten on any occasion, any time of the day. However, soup really shines on a colder day and is reminiscent of cozy days inside.
This spinach mushroom soup is sure to be a favorite. Best of all, it only has simple ingredients, ones you probably already have at the back of your fridge. Spinach and mushrooms are both incredibly versatile and can be utilized in almost all types of dishes. In this soup, the subtle and slightly earthy flavor of the mushroom really sings.
Spinach also plays an integral part in this soup and helps create that beautiful green color. It’s considered a superfood and is rich in many vitamins, including iron, magnesium, and vitamin A. While it is low in calories, spinach boasts an impressive fiber content and lots of antioxidants linked to improving eye health and immune function.
The creaminess comes from the heavy cream, which makes this soup extra filling and hearty. The heavy cream also helps to thicken up the soup, making it satiating for the whole family.
This spinach and mushroom soup also freezes well. As you’ll want to keep coming back for more, we recommend doubling the batch so you can reheat it and get a hot bowl of soup whenever you want.

I've been coming this soup for a couple of years now but misplaced the recipe and had to come back to print it off again. I'm so glad I did bc I noticed when I searched for it that it only had ONE review. This soup deserves FIVE stars and a place in everyone's heart and menu!! So tasty! -and with a luxuriously rich, smooth texture and warmth that just gently comforts all the way down to my toes! The flavors "meld" really well. I can't get enough of it! There are 6 in my household, and at the time I first made this, I believe our age ranges were from 4 or 5 years all the way up to 45. It's a favorite here. I've made a portion just for myself and got caught by my 2 youngest and they were SO disappointed. We top ours with the suggested parmesan but sometimes add bacon crumbles or switch out the cream drizzle with a dollup of sour cream. If you haven't experienced this soup, you are missing out!
