Why You’ll Love Making Button Mushroom Soup
Button mushroom soup is a classic for so many reasons, and once you learn the basics, you’ll make it again and again.
First, button mushrooms are affordable and available at nearly every grocery store, so making button mushroom soup won’t strain your budget.
Second, this soup comes together fast, which makes it perfect for busy weeknights when you still want something homemade.
Third, the flavor of button mushroom soup is incredibly versatile, so you can keep it simple or dress it up with herbs and spices.
Finally, making button mushroom soup from scratch lets you control the thickness, saltiness, and creaminess exactly to your liking.
1. The Best Mushrooms for This Soup
When you decide to make button mushroom soup, you might wonder if you should use only button mushrooms or mix in others.
Button mushrooms are the star here because they have a mild, slightly nutty flavor that blends beautifully with creamy bases.
You can absolutely make button mushroom soup with just white button mushrooms, and that’s what most classic recipes call for.
If you want a deeper taste, try combining button mushrooms with cremini or shiitake, but keep button mushrooms as the main ingredient.
For the best results when making button mushroom soup, look for mushrooms that are firm, dry, and free of slimy spots.
2. Prep Your Button Mushrooms the Right Way
How you prepare your mushrooms makes a huge difference in how to make button mushroom soup that’s not gritty or watery.
Start by wiping each button mushroom with a damp paper towel instead of running them under water, since mushrooms absorb moisture quickly.
If you rinse them too much, your button mushroom soup can end up thin and bland because the mushrooms release extra water.
Slice your button mushrooms evenly so they cook at the same rate, which ensures every spoonful of your soup has consistent bites.
You can chop some mushrooms finely and leave others in thicker slices for a more textured button mushroom soup.
3. Sautéing Builds the Flavor Foundation
The single most important step when you make button mushroom soup is to sauté the mushrooms properly before adding any liquid.
Heat butter and a splash of olive oil in a large pot over medium-high heat so the butter doesn’t burn while you cook.
Add your sliced button mushrooms in a single layer and let them sit without stirring for a few minutes to get golden brown edges.
This browning is called the Maillard reaction, and it’s what gives button mushroom soup that deep, savory umami flavor.
Season with salt at this stage because salt helps draw out moisture, and then cook until the mushrooms shrink and release their juice.
4. Aromatics and Broth for Depth
After your button mushrooms are nicely browned, you’ll want to add aromatics to make button mushroom soup even more flavorful.
Finely diced onion and minced garlic are classic choices, and you can also add a little thyme or rosemary for a herby note.
Cook the onion and garlic for two to three minutes until fragrant, which infuses your button mushroom soup with sweet, savory layers.
Now pour in your broth, and chicken or vegetable broth both work beautifully when making button mushroom soup.
Use about four cups of broth for every pound of button mushrooms, and bring everything to a gentle simmer before blending.
5. Blend and Finish With Cream
The texture you choose for your button mushroom soup is totally up to you, and you can go smooth, chunky, or somewhere in between.
For a velvety button mushroom soup, use an immersion blender directly in the pot and pulse until the mixture is silky.
If you prefer some texture, blend only half of the soup and leave the rest as tender pieces of button mushrooms.
After blending, stir in heavy cream or half-and-half to enrich your button mushroom soup and give it that luscious mouthfeel.
Taste your button mushroom soup and adjust salt and pepper, then finish with a squeeze of lemon juice to brighten all the flavors.
Tips for the Perfect Button Mushroom Soup Every Time
Once you understand the core steps, making button mushroom soup becomes second nature, but a few extra tricks can elevate it further.
1. Don’t Skimp on the Browning
Your button mushroom soup will only taste as good as the color you develop on those mushrooms, so be patient during sautéing.
If the pot looks dry before the mushrooms release their liquid, add a tiny pat of butter rather than more broth or water.
Properly browned mushrooms will give your button mushroom soup a rich, almost meaty flavor that you can’t get any other way.
2. Use Warm Liquid to Prevent Splattering
When you make button mushroom soup, adding cold broth to a hot pot can cause splatters and also cool down the cooking too fast.
Warm your broth in a separate saucepan or microwave it before pouring it into the pot with your mushrooms and aromatics.
This small step helps your button mushroom soup cook evenly and keeps your stovetop cleaner in the process.
3. Add a Splash of Wine (Optional)
Deglazing the pan with a splash of dry white wine is a restaurant trick that works wonders when making button mushroom soup.
After your button mushrooms and aromatics are cooked, pour in the wine and scrape up any browned bits stuck to the bottom.
Let the wine reduce by half before adding broth, and this will add a subtle acidity that balances the cream in your button mushroom soup.
If you prefer to skip alcohol, a teaspoon of sherry vinegar or lemon juice can do a similar job in your button mushroom soup.
How to Serve and Store Button Mushroom Soup
Your button mushroom soup is ready to eat, but how you serve and store it matters for the best experience.
Serve your button mushroom soup hot with a swirl of cream, cracked black pepper, and a sprinkle of fresh parsley or chives.
A slice of crusty bread or garlic toast on the side is perfect for dipping and soaking up every last drop of button mushroom soup.
If you have leftovers, let your button mushroom soup cool completely before transferring it to an airtight container.
Your button mushroom soup will keep in the refrigerator for up to four days, and the flavors only get better as they meld overnight.
You can also freeze button mushroom soup for up to three months, just thaw it in the fridge overnight and reheat gently on the stove.
