Silas walked into the kitchen last week, sniffed the air like a cartoon dog, and said “okay, what is THAT and can I have it right now.” That is the highest form of praise I get in this house. He wasn’t even being dramatic. This creamy mushroom soup does that to people.
I’ve made a lot of soups in my life. Some good, some forgettable, one that Silas still brings up as “the broccoli incident.” But this one earned a permanent spot on our weekly rotation, and once you make it, you’ll get why.
Side Note: If you’ve only ever had canned cream of mushroom soup, please forget everything you think you know. This is a completely different animal. Earthy, rich, silky, and made with actual mushrooms doing actual work.
This recipe is beginner friendly, comes together in under 40 minutes, and uses ingredients you probably already have sitting in your fridge right now.
Honestly, soup season doesn’t need a calendar. I’ve made this in the middle of July with the AC running, standing at the stove in shorts, not caring one bit. Some recipes just don’t follow rules, and this is one of them.
Let’s get into it.
Why This Mushroom Soup Recipe Works So Well
Mushrooms have this deep, savory flavor that food folks call umami. It’s the same flavor that makes soy sauce and parmesan so addictive.
When you sauté mushrooms low and slow before adding liquid, you’re building layers of flavor instead of just simmering everything together and hoping for the best.
That’s the entire secret here. Patience during the sauté step. Everything after that is basically easy mode.

A Quick Word on Choosing Mushrooms
Not all mushrooms behave the same way in soup. Button mushrooms are mild and budget friendly, a solid everyday pick.
Cremini mushrooms, sometimes labeled “baby bella,” bring a slightly deeper flavor for almost the same price. That’s my go-to.
Shiitake mushrooms add a stronger, almost smoky note. A small handful mixed in makes a noticeable difference without overpowering the soup.
Whatever you pick, look for mushrooms that feel firm and dry, not slimy or spotted. Fresh mushrooms make a fresh tasting soup, plain and simple.
What You’ll Need
Ingredients
| Ingredient | Amount |
|---|---|
| Cremini or button mushrooms | 1.5 lbs, sliced |
| Unsalted butter | 4 tablespoons |
| Yellow onion | 1 medium, diced |
| Garlic cloves | 4, minced |
| All-purpose flour | 3 tablespoons |
| Vegetable or chicken broth | 4 cups |
| Heavy cream | 1 cup |
| Fresh thyme | 1 tablespoon, or 1 teaspoon dried |
| Soy sauce | 1 tablespoon |
| Salt and black pepper | to taste |
| Fresh parsley | for garnish |
Tools
- Large soup pot or Dutch oven
- Sharp knife and cutting board
- Wooden spoon
- Immersion blender (or a regular blender)
- Measuring cups and spoons
Quick tip: grab a mix of mushroom varieties if your grocery store has them. Cremini plus a handful of shiitake takes this soup from good to genuinely impressive.
Pro Tips From My Kitchen to Yours
Here’s what I’ve learned making this soup more times than I can count.
- Don’t crowd the pan. If your mushrooms are piled too high, they’ll steam instead of brown, and you lose all that flavor. Work in batches if needed.
- Let the mushrooms release their liquid first, then let it evaporate. This step takes patience but it’s where all the flavor magic happens.
- Soy sauce is not traditional, but it’s my secret weapon. It deepens the umami without making the soup taste Asian-inspired. Trust me on this one.
- Blend to your preferred texture. I like mine mostly smooth with a few chunky mushroom bits left for texture. Totally your call though.
- Add the cream at the very end, off high heat. Boiling cream can cause it to separate, and nobody wants grainy soup.
Cooking Time Efficiency Tip
Slice your mushrooms and dice your onion the night before if you’re short on time. Store them separately in airtight containers in the fridge.
That prep work alone cuts about 10 minutes off your total cooking time, which matters a lot on a weeknight.

How to Make Creamy Mushroom Soup
Step 1: Sauté the Aromatics
Melt the butter in your pot over medium heat. Add the diced onion and cook for 4 to 5 minutes, until softened and translucent.
Add the garlic and cook for another 30 seconds, just until fragrant.
Step 2: Cook the Mushrooms
Add the sliced mushrooms to the pot. Stir to coat them in the butter mixture.
They’ll release a lot of liquid at first. That’s totally normal. Keep cooking, stirring occasionally, until the liquid evaporates and the mushrooms start to brown. This usually takes 10 to 12 minutes.
Side Note: This is the step people rush, and it’s the one step you really shouldn’t. Browned mushrooms equal flavorful soup.
Step 3: Build the Base
Sprinkle the flour over the mushroom mixture and stir well to coat everything evenly. Cook for 1 minute to remove the raw flour taste.
Slowly pour in the broth while stirring constantly, so no lumps form.
Add the thyme and soy sauce. Bring the soup to a gentle simmer and let it cook for 10 minutes, allowing the flavors to come together.
Step 4: Blend It Up
Remove the pot from heat. Using an immersion blender, blend the soup to your desired consistency.
Prefer a fully smooth soup? Blend until silky. Like some texture? Pulse it a few times and stop.
No immersion blender? Carefully transfer the soup in batches to a regular blender.
Step 5: Finish With Cream
Return the pot to low heat if needed. Stir in the heavy cream.
Taste and season with salt and pepper. Let it warm through for a couple of minutes, but don’t let it boil.
Garnish with fresh parsley and serve hot.
Substitutions and Variations
| Original | Swap | Notes |
|---|---|---|
| Heavy cream | Coconut cream | Adds a subtle sweetness, great for dairy-free |
| Butter | Olive oil | Works well for a lighter version |
| All-purpose flour | Cornstarch slurry | Good gluten-free option |
| Chicken broth | Vegetable broth | Makes the soup fully vegetarian |
| Cremini mushrooms | Portobello or wild mushroom mix | Deeper, earthier flavor |

Make Ahead Tips
This soup actually tastes better the next day, once the flavors have had time to settle in.
Make it up to 2 days ahead, store it covered in the fridge, and reheat gently on the stovetop over low heat.
Hold off on adding the cream until you’re ready to serve if you’re making it more than a day in advance. Add it fresh when reheating for the best texture.
Leftovers and Storage
Store leftovers in an airtight container in the fridge for up to 4 days.
To reheat, warm it on the stovetop over low heat, stirring occasionally. Avoid microwaving on high, since it can cause the cream to separate.
Freezing tip: this soup freezes well for up to 3 months, but freeze it before adding the cream. Stir in fresh cream after thawing and reheating.

FAQs Related to Creamy Mushroom Soup
1. Can I make mushroom soup without cream?
Yes. Swap the heavy cream for coconut cream or whole milk. The texture will be slightly lighter but still delicious.
2. What’s the best mushroom for soup?
Cremini mushrooms are the most reliable choice for flavor and texture. A mix with shiitake or portobello adds extra depth.
3. Why is my mushroom soup watery?
This usually happens if the mushrooms weren’t cooked long enough to release and evaporate their liquid before adding the broth. Give that step more time next round.
4. Can I make this soup vegan?
Absolutely. Use olive oil instead of butter, vegetable broth, and full-fat coconut milk instead of heavy cream.
5. How do I thicken mushroom soup?
The flour does most of the thickening work here. For an extra thick soup, blend a larger portion of it or simmer uncovered a few extra minutes.
6. Can I use dried mushrooms instead of fresh?
You can, though the texture and flavor will differ. Rehydrate dried mushrooms in warm water first, then chop and use them in place of fresh, and consider using the soaking liquid as part of your broth for extra depth.
7. Is this soup gluten free?
Not as written, since it uses regular flour. Swap in a cornstarch slurry or a gluten-free flour blend to make it fully gluten free without losing the thick, creamy texture.
