I’ve made countless soups over the years, but this mushroom cream soup with garlic and thyme is the one I return to when I want something deeply comforting yet elegant. It’s the kind of recipe that fills the kitchen with a warm, earthy aroma and makes you slow down, savoring each step as much as the final bowl.
What I love most about this soup is how simple ingredients transform into something rich and velvety. The mushrooms bring depth, the garlic adds warmth, and the thyme ties everything together with its subtle herbal note. It’s cozy enough for a quiet night in, but refined enough to serve to guests without any stress.
What You Need To Make This Recipe
Mushrooms:
Mushrooms are the heart of this soup. I like using cremini or button mushrooms because they’re easy to find and develop a deep, savory flavor once sautéed. You can also mix in a few shiitakes for extra richness if you like.
Garlic:
Fresh garlic adds warmth and a gentle bite that balances the creaminess of the soup. Minced finely, it melts into the base and enhances the earthy flavor of the mushrooms without overpowering them.
Fresh Thyme:
Thyme brings a subtle herbal freshness that pairs beautifully with mushrooms. Fresh thyme is ideal here, as it releases a more aromatic and delicate flavor than dried.
Onion:
Onion creates a flavorful foundation for the soup. When slowly cooked, it becomes soft and slightly sweet, rounding out the savory notes of the mushrooms and garlic.
Butter:
Butter adds richness and depth, helping the mushrooms brown properly and giving the soup its luxurious texture.
Vegetable or Chicken Broth:
The broth forms the body of the soup. Vegetable broth keeps the recipe vegetarian, while chicken broth adds a slightly deeper savory note.
Heavy Cream:
Heavy cream is what gives this soup its silky, indulgent texture. It softens the bold mushroom flavor and creates that classic creamy finish.
Salt and Black Pepper:
Simple seasoning is key. Salt enhances all the flavors, while freshly ground black pepper adds a gentle warmth.
Olive Oil:
A small amount of olive oil helps prevent the butter from burning and adds a subtle fruity note.

How to Make Mushroom Cream Soup with Garlic & Thyme
Sauté the Aromatics
In a large pot, heat the butter and olive oil over medium heat. Add the chopped onion and cook until soft and translucent, stirring occasionally so it doesn’t brown.
Cook the Mushrooms
Add the sliced mushrooms to the pot and cook for several minutes until they release their moisture and begin to brown. This step builds deep flavor, so don’t rush it.
Add Garlic and Thyme
Stir in the minced garlic and fresh thyme. Cook for about 30 seconds, just until fragrant, being careful not to let the garlic burn.
Pour in the Broth
Add the broth and bring the mixture to a gentle simmer. Let it cook for about 10–15 minutes so all the flavors meld together.
Blend the Soup
Using an immersion blender, blend the soup until smooth. You can also carefully transfer it to a blender in batches if needed.
Add the Cream and Season
Return the soup to low heat and stir in the heavy cream. Season with salt and black pepper to taste, warming gently without boiling.
Tips for Making This Recipe
- Don’t overcrowd the mushrooms when cooking; give them space so they brown instead of steaming.
- Use fresh thyme for the best aroma and flavor.
- Blend the soup as smooth or as chunky as you prefer.
- Taste and adjust seasoning after adding the cream, as it can mellow the flavors.
- For extra depth, add a splash of white wine before the broth and let it reduce.
