How to Make Creamy Mushroom Soup
Step-by-Step Instructions:
Step 1: Prepare Your Ingredients Clean and slice all mushrooms uniformly, about 1/4-inch thick. Dice the onion and mince the garlic. Having everything prepped before you start cooking ensures smooth preparation.
Step 2: Sauté the Aromatics Heat butter and olive oil in a large, heavy-bottomed pot over medium heat. Add the diced onion and cook for 3-4 minutes until softened and translucent. Add minced garlic and cook for another 30 seconds until fragrant.
Step 3: Cook the Mushrooms Add the sliced mushrooms to the pot and cook for 8-10 minutes, stirring occasionally. The mushrooms will release their moisture initially, then begin to brown as the liquid evaporates. This browning is crucial for developing deep, rich flavor.
Step 4: Deglaze (Optional) If using white wine, pour it into the pot and scrape up any browned bits from the bottom. Let the wine simmer for 2-3 minutes to cook off the alcohol and concentrate the flavors.
Step 5: Add Broth and Seasonings Pour in the vegetable broth, then add thyme, bay leaf, salt, and pepper. Bring the mixture to a boil, then reduce heat and simmer for 15-20 minutes to allow flavors to meld.
Step 6: Create the Cream Base If you prefer a thicker soup, whisk the flour with a small amount of cold broth until smooth, then stir this mixture into the soup. Remove the bay leaf, then slowly stir in the heavy cream. Heat through for 2-3 minutes, but avoid boiling to prevent curdling.
Step 7: Final Seasoning and Serve Taste and adjust seasoning with additional salt and pepper as needed. Ladle into bowls and garnish with fresh parsley if desired.
