Ingredients You’ll Need

You’ll be amazed by how a handful of pantry staples come together to create such a delicious and satisfying result. Each ingredient plays a key role in building Creamy Mushroom Soup’s depth of flavor, dreamy texture, and gentle color. Here’s what you’ll need and why each is essential:

Mushrooms: The earthy soul of the soup, offering umami richness and bite.
Butter: Adds plenty of richness and ensures a silky base.
Minced garlic: For a flavor boost and aromatic warmth.
Onion powder: Delivers all the sweet, mild bite of onion but blends seamlessly.
Salt: Enhances and ties together all the other flavors.
Ground pepper: Provides a subtle kick to balance the creaminess.
Gluten-free all-purpose flour: The magic that thickens the soup without any gluten.
Gluten-free chicken broth: Lends savory depth and helps keep things light.
Milk: Gives a luxurious, velvety texture to round out the soup.

How to Make

Step 1: Sauté the Butter and Garlic

Start by setting a medium saucepan or skillet over medium heat. Melt the butter until it just begins to foam, then add the minced garlic. Sauté for about 30 seconds until the garlic is wonderfully fragrant but not browned—this brief mingling infuses the entire base of the soup with aromatic flavor.

Step 2: Add Mushrooms and Soften

Stir in the chopped mushrooms, letting them cook for a few minutes. As they soften, you’ll notice their aroma intensifying and their color deepening—they’ll also start to release moisture that melds beautifully with the buttery garlic.

Step 3: Season for Max Flavor

Sprinkle in the onion powder, salt, and ground pepper. Toss everything together, making sure the mushrooms are evenly coated. These seasonings enhance the mushroom’s natural earthiness and bring warm, layered notes to the Creamy Mushroom Soup.

Step 4: Make the Roux

Evenly sprinkle the gluten-free all-purpose flour over the mushroom mixture. Stir constantly for about a minute—this forms a roux, which will thicken the soup later on. Cooking the flour for just a minute removes any raw taste while keeping things gluten-free.

Step 5: Whisk in Broth Gradually

Slowly pour in the gluten-free chicken broth, whisking as you go. Add it in small amounts at first, stirring constantly to prevent lumps. This gentle approach transforms the roux into a silky, lump-free base for your Creamy Mushroom Soup.

Step 6: Add Milk and Simmer to Perfection

Pour in the milk, still whisking, and turn up the heat slightly. Allow the soup to come to a gentle simmer. Whisk frequently as it thickens—this is where the magic happens, turning the mixture into a velvety, glossy soup. If you like it a little thicker or thinner, adjust the heat and cook time to match your perfect texture.

Step 7: Season, Taste, and Serve

Do a final taste and adjust the salt or pepper if needed. Serve your Creamy Mushroom Soup piping hot, straight from the pot, over your favorite grains, proteins, or all on its own.

How to Serve

Garnishes

A swirl of cream, a sprinkle of chopped parsley, or even some crisped mushrooms take your Creamy Mushroom Soup from homey to restaurant-worthy. Try freshly cracked pepper, a drizzle of olive oil, or a pinch of smoked paprika for extra flair.

Side Dishes

This soup is wonderful paired with toasty gluten-free bread, a wedge of focaccia, or a crisp side salad. It’s also lovely with a plate of simply roasted vegetables or a protein like grilled chicken or salmon.

Creative Ways to Present

Impress your dinner guests by serving Creamy Mushroom Soup in small cups or shot glasses as an appetizer. For a cozy weeknight, ladle it over baked potatoes or cooked quinoa for a comforting meal-in-a-bowl.

Make Ahead and Storage

Storing Leftovers

Store any leftover Creamy Mushroom Soup in an airtight container in the fridge for up to 3 days. Give it a good stir before reheating, as it may thicken more while it sits.

Freezing

This soup freezes beautifully. Pour cooled soup into freezer-safe containers or bags, leaving space for expansion. Thaw overnight in the fridge before reheating for the best texture and flavor.

Reheating

Warm up Creamy Mushroom Soup on the stovetop over low heat, stirring frequently. If it’s become a little too thick, simply whisk in a splash of broth or milk until it’s back to silky perfection.

FAQs

Can I make this soup vegan?

Absolutely! Substitute the butter for vegan butter, the milk for your favorite plant-based alternative, and use veggie broth. The result is still a gorgeously creamy, plant-based mushroom soup.

Which mushrooms work best for Creamy Mushroom Soup?

White button, cremini, or baby bella mushrooms are all excellent, but you can blend in a little shiitake or portobello for deeper flavor. Use whatever fresh mushrooms are available and affordable.

Can I use regular flour instead of gluten-free?

Definitely—if you’re not avoiding gluten, swap in regular all-purpose flour in the same amount. It will thicken the soup just as well.

How can I make this soup even more flavorful?

Try adding a dash of tamari or Worcestershire sauce, toss in some fresh chopped herbs like thyme or sage, or finish with a squeeze of lemon for brightness.

Is this Creamy Mushroom Soup good as a sauce?

Absolutely! This recipe pulls double-duty as a luscious sauce—drizzle it over steak, chicken, mashed potatoes, roasted veggies, or gluten-free pasta for a next-level meal.
