Ingredients You’ll Need
Creating this Decadent and Creamy Mushroom Soup doesn’t require a huge list of fancy ingredients, but each component plays a key role in building flavor and giving the soup its signature silkiness. Let’s take a quick tour of what you’ll need and why it matters:
- Unsalted Butter: Lends rich flavor and helps sauté the aromatics for a wonderful depth.
- Olive Oil: Works alongside the butter to keep things from burning and adds a subtle fruity note.
- Yellow Onion (diced): The foundation of flavorful soup, adding natural sweetness and umami.
- Garlic (minced): A must for fragrant, delicious undertones that highlight the earthiness of mushrooms.
- Mixed Mushrooms (cremini, shiitake, button, sliced): The star of the show! Combining mushroom varieties makes the flavor deep and complex.
- Dried Thyme: Brings herby warmth and an unmistakable French-inspired aroma.
- Salt: Essential for seasoning and bringing all the flavors together.
- Black Pepper: Adds a hint of spicy warmth and lift to the earthy mushrooms.
- All-Purpose Flour: The secret to thickening the soup and creating that luscious, creamy body.
- Vegetable or Chicken Broth: The flavorful liquid base—choose whichever suits your dietary needs.
- Heavy Cream: The absolute key to a soup that’s silky, rich, and completely indulgent.
- Whole Milk: Lightens up the cream while still keeping things luscious.
- Soy Sauce or Tamari: Just a splash gives a savory umami punch and rounds out the flavor beautifully.
- Chopped Fresh Parsley (for garnish): Brightens up each bowl with color and a burst of freshness.
How to Make Decadent and Creamy Mushroom Soup
Step 1: Start With a Flavorful Base
Heat the butter and olive oil together in a large soup pot over medium heat. Once the butter is melted and bubbling gently, add the diced onion. Cook, stirring occasionally, until the onions turn soft and translucent—about five minutes. Add the garlic and give it just a minute more, releasing all those incredible aromas. This simple start layers your soup with aromatic goodness right from the get-go.
Step 2: Sauté the Mushrooms and Seasonings
Add all those wonderful mushrooms to the pot, along with the dried thyme, salt, and black pepper. Sauté everything, stirring occasionally. Be patient, and keep cooking for 10 to 12 minutes until the mushrooms have released most of their moisture and start attaining a deep golden brown. At this point, your kitchen will smell absolutely heavenly, with each mushroom soaking up the herby flavors.
Step 3: Create the Creamy Foundation
Sprinkle the flour evenly over the sautéed mushrooms. Stir well so the flour coats every bit—this step is essential for getting that signature thick and creamy texture. Let it cook for another minute or two, watching closely so nothing sticks. The flour will blend into the mushroom mixture, ensuring a lump-free result when you add the broth.
Step 4: Simmer to Perfection
Gradually pour in the broth, stirring constantly to incorporate the flour and prevent any clumping. Bring everything to a gentle boil, then immediately reduce the heat to a simmer. Let the soup bubble away for about ten minutes. This not only thickens the base but allows the flavors to meld into one harmonious whole. If you’re after an ultra-smooth texture, you can blend all or part of the soup before the next step.
Step 5: Add the Creamy Goodness and Finish
Now for the magic touch: Stir in the heavy cream, whole milk, and a splash of soy sauce or tamari. Let the soup gently simmer for another five minutes or so, until everything is piping hot and the soup is decadently creamy and just thick enough to coat the back of a spoon. Taste and adjust your seasonings if needed. Ladle your Decadent and Creamy Mushroom Soup into bowls, topping each with a sprinkle of fresh parsley. Dive in and savor every spoonful!
How to Serve Decadent and Creamy Mushroom Soup

Garnishes
This is one recipe where a little bit of garnish goes a long way. A generous sprinkle of chopped fresh parsley instantly brightens up the earthy tones of your Decadent and Creamy Mushroom Soup, but don’t stop there! Try a drizzle of good olive oil, a few shavings of parmesan, or even a handful of crispy fried mushrooms for added texture and flair. Each garnish brings new excitement to every bowl.
Side Dishes
The richness of this Decadent and Creamy Mushroom Soup pairs beautifully with humble sides. Think thick slices of toasted sourdough, a hunk of crusty French bread, or a warm, buttered baguette to soak up every last drop. For a lighter touch, serve alongside a simple mixed green salad tossed in a zippy vinaigrette—the contrast of flavors and textures is pure bliss.
Creative Ways to Present
Get playful with your presentation! Serve the soup in small espresso cups for a chic appetizer at your next dinner party. Pour it into rustic bread bowls for cozy gatherings that invite dipping and sharing. For a truly elegant touch, float a herbed crouton or swirl a spoonful of crème fraîche on top. However you serve it, Decadent and Creamy Mushroom Soup adds warmth and a touch of luxury to any table.
Make Ahead and Storage
Storing Leftovers
Homemade Decadent and Creamy Mushroom Soup stores beautifully in the refrigerator. Let the soup cool completely before transferring it to airtight containers. It will keep for up to four days and often tastes even better the next day as the flavors continue to develop and deepen.
Freezing
While cream-based soups can sometimes separate upon freezing, this one holds up surprisingly well with a few considerations. For the best results, cool the soup completely and freeze in airtight containers, leaving a bit of space at the top for expansion. You might notice a little texture change after thawing, but a quick stir or blend will bring it right back to silky perfection.
Reheating
When you’re ready for round two, reheat Decadent and Creamy Mushroom Soup gently on the stove over low heat, stirring often. If the soup has thickened in the fridge, add a splash of broth or milk to loosen it up. Avoid boiling to keep the cream smooth and uncurdled—a gentle simmer is all it needs to become deliciously cozy again.
FAQs
Can I make this Decadent and Creamy Mushroom Soup vegan?
Absolutely! Swap the butter for a plant-based alternative, use full-fat coconut milk or cashew cream in place of the dairy, and choose vegetable broth. The soup remains just as luscious and hearty—perfect for anyone following a vegan diet.
What’s the best mushroom mix to use?
Combining cremini, shiitake, and button mushrooms yields the greatest depth of flavor, but feel free to experiment with whatever fresh mushrooms you find. Different varieties like oyster or portobello add their own unique notes, so make this soup your own!
Can I make Decadent and Creamy Mushroom Soup ahead of time for entertaining?
This soup is a perfect make-ahead dish. Prepare it a day or two in advance, refrigerate, then reheat gently before serving. The flavors will continue to develop, making it even more delicious by the time your guests arrive.
How can I thicken the soup if it’s too thin?
If your soup is looking a bit thin, simply simmer it uncovered for a few extra minutes to allow excess liquid to evaporate. Alternatively, mix a small amount of flour with cold milk, stir into the simmering soup, and cook for a few minutes until it thickens up.
Is it possible to freeze Decadent and Creamy Mushroom Soup with the cream added?
Yes, but do so knowing there might be some separation once thawed. Give the soup a good stir or a quick blend after reheating, and it should return to its creamy former glory. For best results, you can freeze the soup before adding cream and stir in the cream after reheating.
