Why You’ll Love Creamy Mushroom Soup Recipe
This mushroom soup delivers restaurant-style flavor using simple, familiar ingredients. The mushrooms are cooked patiently to concentrate their flavor before being simmered with aromatics and broth.
Blending the soup creates an exceptionally smooth texture, and a final splash of heavy cream adds richness without overpowering the mushrooms. It’s also easy to customize: you can experiment with different mushroom varieties, adjust the consistency, or leave part of the soup chunky for additional texture.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
- Unsalted butter
- Fresh sliced mushrooms
- Salt
- Yellow onion, diced
- All-purpose flour
- Chicken broth
- Water
- Fresh thyme sprigs
- Garlic cloves
- Heavy cream
- Freshly ground black pepper
- Fresh thyme leaves for garnish
Directions
- Melt the butter in a large soup pot over medium-high heat. Add the sliced mushrooms with a pinch of salt and cook until they release their moisture.
- Lower the heat and continue cooking the mushrooms, stirring regularly, until their liquid has evaporated and the mushrooms become deeply caramelized. Reserve a few attractive mushroom slices for garnishing if desired.
- Add the diced onion and cook until softened and translucent.
- Sprinkle in the flour and stir well. Cook briefly so the flour loses its raw taste.
- Pour in the chicken broth and water. Add the fresh thyme bundle and whole garlic cloves. Reduce the heat and allow the soup to simmer gently for about 1 hour so the flavors can develop.
- Remove the thyme sprigs. Carefully blend the soup in batches until smooth. When using a countertop blender with hot soup, avoid overfilling it and allow steam to escape safely according to the blender manufacturer’s instructions. An immersion blender can also be used.
- Return the blended soup to the pot and stir in the heavy cream. If the consistency is thicker than you prefer, add a little additional broth or water.
- Taste and season with salt and freshly ground black pepper. Ladle into bowls and finish with reserved mushroom slices and fresh thyme leaves.
Servings and timing

Preparation time: 10 minutes
Cooking time: 1 hour 25 minutes
Total time: 1 hour 35 minutes
Variations
For a more complex mushroom flavor, replace some of the standard mushrooms with cremini, shiitake, or rehydrated porcini mushrooms.
For a chunkier soup, blend only half or three-quarters of the mixture and leave the remaining mushrooms intact. You can also reserve additional caramelized mushrooms and stir them back into the finished soup.
For a lighter version, substitute half-and-half for some or all of the heavy cream. The finished soup will be slightly less rich but still creamy.
For a vegetarian version, replace the chicken broth with a flavorful vegetable or mushroom broth.
For extra herbal flavor, add a small amount of rosemary alongside the thyme while the soup simmers, removing the sprig before blending.
Storage/Reheating
Allow leftover mushroom soup to cool before transferring it to an airtight container. Store it in the refrigerator for up to 4 days for best quality.
Reheat the soup gently in a saucepan over medium-low heat, stirring occasionally until completely heated through. If it has thickened during refrigeration, stir in a splash of broth, water, or cream until it reaches your preferred consistency.
Individual portions can also be reheated in the microwave. Heat in short intervals, stirring between each interval to encourage even heating.
The soup can be frozen for up to 2 months. Because it contains heavy cream, the texture may separate slightly after freezing. Thaw overnight in the refrigerator and reheat slowly while whisking or stirring well to restore a smoother consistency.
FAQs
What mushrooms are best for creamy mushroom soup?
White button mushrooms are an easy and affordable choice, but cremini mushrooms provide a somewhat deeper flavor. You can also combine several varieties, such as cremini, shiitake, and porcini, for a more complex soup.
Why should I caramelize the mushrooms?
Caramelization concentrates the mushrooms’ natural flavor and creates deeper savory notes. Allowing their released moisture to evaporate before continuing to cook them is an important part of developing the soup’s rich flavor.
Can I make this mushroom soup vegetarian?
Yes. Simply replace the chicken broth with vegetable broth or mushroom broth. A good mushroom broth can intensify the earthy character of the finished soup.
Can I make creamy mushroom soup without heavy cream?
Yes. Half-and-half can produce a lighter soup, while whole milk can also work, although the final result will be less rich. For a dairy-free version, an unsweetened plant-based cooking cream can be used.
Do I have to blend the soup completely?
No. Blend it completely for a silky, smooth soup, or blend only part of it if you prefer pieces of mushroom throughout. An immersion blender makes it especially easy to control the final texture.
How can I make the soup thicker?
Let the finished soup simmer uncovered for a few additional minutes. The flour in the recipe already provides some thickening, so the soup should naturally develop a creamy consistency as it cooks.
How can I thin mushroom soup if it is too thick?
Gradually stir in additional chicken broth, vegetable broth, or water until the soup reaches your preferred consistency. A small splash of cream can also thin it while maintaining its richness.
Can I prepare this soup ahead of time?
Yes. This is an excellent make-ahead soup because the flavors remain rich after refrigeration. Prepare it in advance, refrigerate it in an airtight container, and gently reheat before serving.
What can I serve with creamy mushroom soup?
Crusty bread, garlic bread, toasted sourdough, or a simple green salad are excellent accompaniments. Smaller portions also work well as a starter before roasted chicken, steak, or another hearty main course.
Can creamy mushroom soup be frozen?
Yes. Freeze cooled soup in airtight freezer-safe containers for up to 2 months. Leave a little room for expansion. After thawing, reheat gently and stir thoroughly, as cream-based soups can separate slightly after freezing.
Conclusion
Creamy mushroom soup transforms everyday mushrooms into a deeply flavorful, comforting dish. The key is giving the mushrooms enough time to release their moisture and caramelize before adding the broth and aromatics. That extra patience creates the rich mushroom flavor that makes this soup stand out.
With its silky consistency, fresh thyme aroma, and creamy finish, this soup is satisfying enough for a cozy meal while still being elegant enough to serve as a starter for a special dinner.
