Why This Mushroom Soup is a Must-Try

Ingredients
Here’s everything you’ll need to create your own comforting pot of mushroom soup:
-
2 tablespoons olive oil or unsalted butter
-
1 medium yellow onion, finely chopped
-
2 garlic cloves, minced
-
1 pound (450g) fresh mushrooms (white button, cremini, or a mix), sliced
-
4 cups vegetable or chicken broth
-
1 cup whole milk or half-and-half (optional for creaminess)
-
2 tablespoons all-purpose flour (to thicken the soup)
-
Salt and freshly ground black pepper to taste
-
1 teaspoon dried thyme or 1 tablespoon fresh thyme leaves
-
Optional: ¼ cup grated Parmesan cheese
-
Fresh parsley or chives for garnish
Note: For a vegan version, use plant-based milk and skip the Parmesan cheese or replace with nutritional yeast.
Step-by-Step Instructions
1. Sauté the Aromatics
Begin by heating the olive oil or butter in a large soup pot over medium heat. Once hot, add the chopped onions and cook until translucent, about 5–6 minutes. Add the garlic and sauté for another minute until fragrant. These aromatics are the flavor base of your soup, so take your time to let them cook gently.
2. Cook the Mushrooms
Add the sliced mushrooms to the pot and stir well to combine with the onion and garlic mixture. Cook the mushrooms for 8–10 minutes, stirring occasionally. They will release their moisture, then begin to brown and caramelize slightly. This step is critical for developing that deep, savory mushroom flavor.
3. Add the Flour
Sprinkle the flour over the mushrooms and stir to coat. This will help thicken your soup. Cook the flour for 2–3 minutes to eliminate any raw flour taste.
4. Deglaze and Simmer
Slowly pour in the broth while stirring continuously to prevent lumps. Scrape the bottom of the pot to release all the flavor-packed brown bits. Bring the mixture to a boil, then reduce the heat and let it simmer for 15–20 minutes. The soup will begin to thicken and the flavors will meld beautifully.
5. Add Creaminess
At this stage, stir in your milk or half-and-half for a creamy finish. If you prefer a lighter broth, feel free to skip this or use a smaller amount. Add the thyme, salt, and pepper, and let the soup simmer for another 5 minutes.
6. Blend (Optional)
If you prefer a smooth soup, use an immersion blender to puree the soup right in the pot. Alternatively, you can carefully transfer it to a countertop blender in batches. If you like texture, leave some mushroom slices whole or only partially blend.
7. Add Final Touches
Stir in the grated Parmesan cheese (if using), adjust seasoning, and let the soup rest for a few minutes. Garnish with chopped fresh herbs like parsley or chives before serving.
How to Serve Mushroom Soup
This soup is incredibly flexible and can be served in many ways:
-
As a starter: Pair with crusty bread or garlic toast.
-
As a light meal: Serve with a green salad or grilled cheese sandwich.
-
As a dinner option: Add cooked wild rice, barley, or even shredded rotisserie chicken for a heartier dish.
Tips for the Best Mushroom Soup
-
Use a mix of mushrooms for deeper flavor. Combining cremini, shiitake, and button mushrooms adds complexity.
-
Don’t skip the browning process when cooking mushrooms. It enhances the soup’s savory depth.
-
Make it vegan by using olive oil instead of butter, vegetable broth, and plant-based milk.
-
Add wine or sherry when deglazing the pot (optional) to create extra depth and aroma.
-
Store leftovers in the fridge for up to 4 days or freeze in airtight containers for up to 3 months.
