Introduction
There's something about mushroom soup that feels deeply comforting - earthy, savory, and simple in the best way. But it doesn't need heavy cream to get there.
This version leans into what mushrooms already do well. When you give them time to brown properly, they release a depth of flavor that feels rich all on its own. A quick flour roux builds body, vegetable broth keeps it clean, and just a splash of milk softens the edges without weighing it down.
The soy sauce might seem small, but it's important. It subtly enhances the umami and makes the entire bowl taste fuller and more balanced.
If you enjoy this lighter approach, you might also like Rustic Mushroom Soup with Thyme and White Wine, or something heartier like Comforting Chicken & Rice Soup (No Mushy Rice). And if mushrooms are your thing, don't miss the Simple Sautéed Mushroom Toasts - a great companion to a bowl like this.

Why This Recipe Works
Traditional mushroom soup leans heavily on cream for richness. This version builds flavor differently.
Browning the mushrooms properly concentrates their natural umami. Cooking the flour briefly with olive oil creates a light roux that thickens the broth without heaviness. Vegetable broth forms the backbone, while milk adds gentle creaminess without overpowering the mushrooms.
A splash of soy sauce enhances savoriness without making the soup taste Asian-inspired - it simply deepens the flavor. The result is balanced, comforting, and surprisingly rich without being heavy.
Ingredient Notes
Mushrooms (Portobello, Cremini, or Mixed)
A combination works best. Portobello adds depth, while cremini brings balanced earthiness. Rough-chopping some of the mushrooms adds body and texture.
Olive Oil
Used in stages to build flavor and properly cook the flour. Don't skip dividing it.
All-Purpose Flour
Creates a light thickening base. Cook it briefly to eliminate any raw taste.
Vegetable Broth
Choose a flavorful, high-quality broth. Since there's no cream, the broth matters more.
Milk (Full-Fat Preferred)
Adds softness and slight richness without turning the soup heavy.
Thyme & Rosemary
Thyme pairs beautifully with mushrooms. Rosemary adds a subtle piney depth - use lightly.
Soy Sauce
Enhances umami. It won't dominate the flavor.
Tips for Best Results
- Don't overcrowd the mushrooms - they should brown, not steam.
- Let mushrooms release moisture before stirring too much.
- Cook the flour thoroughly for 1 minute to avoid a raw taste.
- Add broth slowly and whisk to prevent lumps.
- Simmer uncovered to allow the soup to thicken naturally.
- Taste at the end and adjust salt carefully - soy sauce adds saltiness.
Variations and Substitutions
- Make it dairy-free by using unsweetened oat milk or almond milk.
- Add a splash of dry white wine after browning mushrooms.
- Blend half the soup to achieve a smoother texture while retaining some chunkiness.
- Add fresh parsley at the end for brightness.
- Stir in a spoonful of Greek yogurt before serving for a tangy finish.
Storage and Reheating
Refrigerator:
Store in an airtight container for up to 4 days.
Freezer:
Freeze for up to 2 months. Texture may change slightly due to milk but will still taste great.
Reheating:
Warm gently on the stovetop over medium-low heat, stirring occasionally. Add a splash of broth or milk if it thickens too much.
Frequently Asked Questions
Can I make this completely dairy-free?
Yes. Use plant-based milk and ensure your broth is vegan.
Can I skip the flour?
You can, but the soup will be thinner. Alternatively, blend more of the soup for thickness.
What mushrooms are best?
A mix of cremini and portobello gives the best balance of flavor and texture.
Does it taste like soy sauce?
No. It simply enhances depth and savoriness.
Serving Suggestions
- Serve with crusty sourdough or baguette.
- Pair with a simple green salad.
- Top with reserved sautéed mushrooms and a drizzle of olive oil.
- Add cracked black pepper and fresh thyme before serving.
Make It Your Own
This soup is a foundation.
Add wild mushrooms when they're in season. Stir in spinach at the end. Finish with truffle oil for a richer feel. Blend completely for a velvety texture or leave it rustic and chunky.
Cooking without cream doesn't mean sacrificing comfort - it just means building flavor more intentionally.
This is the kind of soup you make once and keep coming back to all season.
Recipe
Mushroom Soup without Cream
Ingredients
- 2 tablespoons olive oil, divided
- 1 large onion, diced
- 3 garlic cloves, minced
- 18 ~ 20 oz mushrooms, Portobello, cremini, or a mix
- ½ cup all-purpose flour
- 4 cup vegetable broth
- 1 cup Full-fat cow milk
- 1 teaspoon thyme leaves
- ½ teaspoon chopped rosemary
- 1 tablespoon soy sauce
- salt & black pepper to taste
Instructions
- Clean the mushrooms by rinsing quickly under cold water and patting dry (do not soak). Slice half of the mushrooms and roughly chop the remaining half. Set aside.
- Heat 1 tablespoon olive oil in a large pot or Dutch oven over medium-high heat. Add the onion and cook until softened, about 4 minutes. Add the garlic and cook for 1 minute, until fragrant.
- Add the mushrooms along with a generous pinch of salt and pepper. Cook, stirring occasionally, until the mushrooms release their moisture and begin to brown, 8-10 minutes. Spoon out about 3 tablespoons of mushrooms and reserve for garnish, if desired.
- Stir in the remaining 1 tablespoon olive oil and the flour. Cook, stirring constantly, for 1 minute, forming a thick paste.
- Slowly add the vegetable broth, stirring to scrape up any flour from the bottom of the pot. Bring to a simmer, then reduce heat to medium-low. Stir in the milk, thyme, and rosemary.
- Simmer uncovered, stirring occasionally, for 15-20 minutes, until the soup thickens slightly.
- Stir in the soy sauce, taste, and adjust seasoning as needed. Ladle into bowls, top with reserved mushrooms and a drizzle of olive oil, and serve warm with crusty bread.
