Loaded Creamy Mushroom Soup
Ingredients
Method
- In a large pot over medium-high heat, melt the butter with the olive oil. Add the diced onion and cook, stirring often, until softened, about 2 to 3 minutes. Stir in the minced garlic and cook until fragrant, roughly 1 minute.
- Add the sliced cremini mushrooms and 2 teaspoons of the chopped thyme. Cook, stirring occasionally, until the mushrooms release their liquid and start to brown, about 5 minutes. Pour in the Marsala wine and let it cook down for 3 minutes, scraping up any browned bits from the bottom of the pot.
- Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 2 minutes to remove the raw flour taste. Slowly pour in the chicken broth while stirring continuously, then bring the soup to a boil. Reduce the heat to low-medium, add the salt, pepper, and crumbled beef bouillon cubes, and stir to combine.
- Cover the pot and let the soup simmer gently for 10 to 15 minutes, stirring occasionally, until it thickens to your liking.
- Reduce the heat to low and stir in the heavy cream. Warm the soup gently without letting it boil. Taste and adjust the salt and pepper as needed.
- Remove from heat and stir in the chopped parsley and remaining 2 teaspoons of thyme. Ladle into bowls and serve warm.

Let us know how it was!Why This Loaded Creamy Mushroom Soup Works
I know what you’re thinking. Hot soup in the middle of summer? Trust me, I get it. The first time I made this loaded creamy mushroom soup, it was July in Los Angeles, and my kitchen felt like a sauna. But here’s the thing. Sometimes you just crave that deep, earthy comfort that only a bowl of creamy soup can deliver. And when that craving hits, you don’t care what the thermometer says.
This isn’t your average cream of mushroom soup from a can. We’re talking layers of flavor from browned cremini mushrooms, a splash of Marsala wine, and a velvety broth that coats every spoonful. The secret? A proper roux, good bouillon, and not skimping on the cream. Plus, it’s ready in about 40 minutes. One pot. Minimal cleanup. Maximum satisfaction.
So yeah, I crank up the AC, pour myself a glass of iced tea, and make this loaded creamy mushroom soup even when it’s 90 degrees outside. And you should too. Because good comfort food doesn’t have a season.
Ingredients You’ll Need
Let’s talk about what goes into this creamy mushroom soup recipe. The ingredient list is straightforward, but each one pulls its weight. Here’s the breakdown:
- Cremini mushrooms 1 ½ pounds. These are your workhorses. Baby bellas, same thing. They’ve got that deep, earthy flavor that white buttons just can’t match. Don’t skimp here.
- Unsalted butter and olive oil Half a cup of butter plus a tablespoon of oil. The butter brings richness, the oil keeps it from burning. California olive oil if you’ve got it.
- Yellow onion and garlic The aromatic foundation. One large onion, finely diced. Four cloves of garlic, minced. This is where the savory base starts.
- Fresh thyme Four teaspoons total, divided. Fresh makes a difference here. Dried won’t give you that bright, herbal lift.
- Marsala wine Half a cup. This adds a subtle sweetness and depth that’s hard to replicate. Dry sherry works too if that’s what you have.
- All-purpose flour Six tablespoons. This is your thickener. Don’t skip the roux step, it’s what gives the soup that luxurious body.
- Low-sodium chicken broth Four cups. Gives you control over the salt level.
- Beef bouillon cubes Two cubes, crumbled. This is the umami bomb. Sounds weird maybe, but trust me, it takes the mushroom flavor to another level.
- Heavy cream One cup. For that silky, velvety finish. Half-and-half works too if you want something lighter.
- Fresh parsley Half a tablespoon, chopped. For brightness at the end.
No heavy cream? Use half-and-half or even full-fat coconut milk for a dairy-free option. The texture will be slightly different, but still delicious.
How to Make Loaded Creamy Mushroom Soup
Alright, let’s get cooking. I’ll walk you through the four main stages. Each one builds on the last, so don’t rush.
Stage 1: Build the Aromatic Base
Start by melting the butter with the olive oil in a large pot over medium-high heat. Once it’s bubbling, toss in the diced onion. Cook it for about 2 to 3 minutes, stirring often, until it turns translucent and starts to soften. Then add the minced garlic and cook for another minute until it’s fragrant. Your kitchen should already smell amazing at this point.
Stage 2: Brown the Mushrooms
Add the sliced cremini mushrooms and 2 teaspoons of the chopped thyme. Here’s where patience pays off. Let the mushrooms cook without stirring too much at first. They’ll release a ton of liquid. Keep cooking until that liquid evaporates and the mushrooms start to brown. This takes about 5 minutes. That browning is the Maillard reaction, which is just a fancy way of saying flavor is happening. Pour in the Marsala wine and scrape up any browned bits from the bottom of the pot. Let it cook down for 3 minutes.
Stage 3: Make the Roux and Simmer
Sprinkle the flour over the mushroom mixture and stir until everything is well coated. Cook this for 2 minutes to get rid of that raw flour taste. This roux is what gives your loaded creamy mushroom soup that thick, luxurious texture. Slowly pour in the chicken broth while stirring continuously, then bring the soup to a boil. Reduce the heat to low-medium, add the salt, pepper, and crumbled beef bouillon cubes. Cover and let it simmer gently for 10 to 15 minutes, stirring occasionally, until it thickens to your liking.
Stage 4: Finish with Cream
Reduce the heat to low and stir in the heavy cream. Warm the soup gently without letting it boil. Boiling after adding cream can cause it to curdle, and nobody wants that. Taste and adjust the salt and pepper as needed. Remove from heat and stir in the chopped parsley and remaining 2 teaspoons of thyme. Ladle into bowls and serve warm.
Tips for the Best Mushroom Soup
Over the years, I’ve learned a few things that make this creamy mushroom soup recipe really shine. Here are the ones that matter most:
Texture Targets
What to look for: The soup is ready when it coats the back of a spoon. If you want it even thicker, use an immersion blender to puree half the batch right in the pot. This gives you a creamy base with some mushroom chunks for texture. If it’s too thick, thin it with a little extra broth.
- Don’t skip the roux. The flour and butter mixture is what gives this soup its body. Without it, you’ll end up with thin, watery soup. Six tablespoons of flour might seem like a lot, but it’s exactly right for this amount of liquid.
- Brown those mushrooms properly. Crowding the pan is the biggest mistake. Give them space to release moisture and then caramelize. That deep brown color equals deep flavor.
- Never let the soup boil after adding cream. This is non-negotiable. High heat will cause the cream to separate and curdle. Keep it at a gentle simmer or low heat.
- Use good broth. The beef bouillon cubes add a savory depth that chicken broth alone can’t provide. If you want to skip them, use a really good mushroom or vegetable broth instead.
- Taste as you go. Salt levels can vary depending on your broth and bouillon. Adjust at the end, not the beginning.
Variations to Try
This loaded creamy mushroom soup is pretty perfect as is, but I love that it’s flexible. Here are some ways to switch it up:
- Dairy-free version: Swap the butter for coconut oil and use full-fat coconut milk instead of heavy cream. It sounds unusual, but coconut milk pairs beautifully with mushrooms. The texture stays creamy and rich.
- Gluten-free option: Use a 1:1 gluten-free all-purpose flour blend for the roux. It works just as well for thickening.
- Make it vegan: Combine the dairy-free and gluten-free swaps above. Use vegetable broth instead of chicken broth and skip the beef bouillon. Add a tablespoon of soy sauce or tamari for extra umami.
- Add some heat: A pinch of red pepper flakes or a dash of hot sauce at the end gives it a nice kick.
- Extra vegetables: Sauté a diced carrot or celery rib with the onion for more depth.
These are optional additions, not part of the base recipe. But they’re fun to experiment with once you’ve made the original a few times.
What to Serve with Mushroom Soup
A bowl of this loaded creamy mushroom soup is pretty satisfying on its own, but pairing it with the right side turns it into a full meal. Here are my go-to options:
- Crusty sourdough bread San Francisco-style if you can find it. Toast it, rub it with a cut garlic clove, and dip it in the soup. Absolute heaven.
- Simple green salad A light vinaigrette with mixed greens, maybe some shaved parmesan. The acidity cuts through the richness of the soup.
- Grilled cheese sandwich Classic comfort combo. Use a sharp cheddar or gruyere for extra flavor.
- Roasted vegetables Asparagus, broccoli, or Brussels sprouts roasted with olive oil and salt. Keeps things on the healthier side.
For a lighter meal, just serve the soup with a handful of crackers or some crusty bread. It’s flexible like that.
How to Store and Freeze Leftovers
This soup stores beautifully, which makes it perfect for meal prep. Here’s what you need to know:
Refrigerator: Store in an airtight container for up to 4 days. Reheat gently on the stovetop over medium-low heat, stirring often. Don’t let it come to a boil to avoid the cream separating. If it thickens too much in the fridge, add a splash of broth or water when reheating.
Freezer: This soup freezes well for up to 3 months. For best results, freeze it before adding the cream. Let the base cool completely, then transfer to freezer-safe containers or zip-top bags. When you’re ready to eat, thaw overnight in the fridge, reheat gently, and stir in the cream at the end. If you freeze it with the cream already added, the texture might change slightly, but it’s still delicious.
