The creamy texture and soft mushrooms mixed with the savory flavors of Worcestershire and sage make this the ultimate vegetable soup to warm you up in the winter and serve as a delicious appetizer or a side dish along with Rice Dressing with Sausage or the BEST Garlic Parmesan Green Beans.

As a kid, you couldn't put me within 2 miles of a mushroom. Now, I'm like funk me up with a Gorgonzola Risotto with Mushrooms!

Ingredient Notes and Substitutions

Mushrooms. Use an assortment for the most unique flavor and texture, similar to our Mushroom Truffle Risotto. We used blue oyster, shiitake, and cremini. You could add some lion's mane to that mix as well! The more types you use, the more flavor you'll get.
Herbs. Fresh herbs will be best in this soup. They will be subtle but tasty. Dried herbs can overpower the mushrooms. Make sure to dial back the amount of herbs you use if you use dry. I typically use fresh sage, thyme, and parsley.
Mascarpone. If you don't have mascarpone, you could substitute heavy cream in equal parts. But the mascarpone adds a unique subtle flavor to it. If you really love mascarpone, try our Mascarpone Toast with Lox.

How to Make Creamy Mushroom Mascarpone Soup

Step 1: Start by bringing a large dutch oven to medium heat. Then add butter and melt until the foam fizzles out. Add the onions and mushrooms. Stir for about 8 minutes until the mushrooms have softened and the onions are translucent. You should start smelling the woody aroma of the shiitakes if you used my combination. Season with salt occasionally.

Sauteed mushrooms and onions with fresh herbs added.

Step 2: Once the mushrooms and onions are soft add in the sage, thyme, salt, pepper, and nutmeg and combine. Then stir in the Worcestershire and wait until it starts simmering.

Chicken broth added to the soup to simmer.

Step 3: Add the chicken broth and bring to a simmer. Simmer for 15 minutes, stirring occasionally.

Blending the soup with an immersion blender.

Step 4: Transfer half of the soup to a blender and process using the pulse button for a max of 6 seconds. This portion of the soup should be broken down but not pureed. Transfer back to the soup and stir to combine. Stir in half of the chopped parsley. Or you can use an immersion blender as shown above.

Step 5: To thicken the soup, add the flour to the milk and whisk together. Then stir the milk into the soup and simmer for another 15 minutes. Add the mascarpone and mix until it dissipates completely into the soup adding the final touch of the creamy texture and nutty, buttery flavor.

Serve with crusty Italian bread and garnish with the rest of the parsley. This creamy mushroom soup is perfect for the fall. If you're looking for something similar but more filling try our Creamy Mushroom Pasta.

Pro-Tips

Use a blender to pulse the soup but not blend completely. If you don't have a blender you can use an immersion blender and just pulse it a couple of times in the pot to blend up some of the mushrooms. The blending will make it a creamy mushroom soup!
I recommend using an assortment of mushrooms so that there is more texture and flavor. One mushroom would make this soup feel very one-dimensional.

Recipe FAQs

What thickens creamy mushroom soup?

We use a milk and flour slurry and simmer it into the soup to thicken it. You can also use a corn starch and water slurry to thicken it up.

Does mushroom soup reheat well?

The soup will be slightly thicker upon reheating, so you can either add some broth when reheating over the stovetop or just microwave it and eat it as is. I found both ways to work well.

What Can I Substitute for Dairy?

You can substitute cornstarch and water slurry for the milk and flour mixture to help thicken the soup. You can also substitute coconut milk for the mascarpone.
