Ingredients
Mushroom and Onion Base
- 3 tablespoons olive oil
- 1 ½ pounds mixed mushrooms, trimmed and sliced ¼-inch thick
- 2 cups diced yellow onions
- 3 tablespoons unsalted butter
Seasoning and Thickening
- ¼ cup all-purpose flour (gluten-free flour can be used as an alternative)
- 4 teaspoons sweet mild paprika
- 1 tablespoon chopped fresh dill, or 2 teaspoons dried dill
- Kosher salt and cracked black pepper, to taste
Liquids and Flavor Enhancers
- ½ cup dry white wine (such as Sauvignon Blanc)
- 3 cups low-sodium chicken broth or vegetable broth
- 2 tablespoons low-sodium soy sauce
- 1 ½ cups whole milk
- ¾ cup sour cream
- 2 tablespoons white wine vinegar or sherry vinegar
Garnish
- ½ cup chopped fresh parsley
Instructions
- Prepare the vegetables: Clean and trim the mixed mushrooms then slice them into ¼-inch thick pieces. Dice the yellow onions finely to create the flavor base for the soup.
- Sauté mushrooms and onions: Heat olive oil in a large pot over medium heat. Add the sliced mushrooms and sauté until tender and browned, about 8-10 minutes. Next, add the diced onions and cook until translucent and soft, approximately 5 minutes. Stir in the unsalted butter and allow it to melt evenly throughout the mixture.
- Add flour and paprika: Sprinkle the all-purpose flour over the mushroom and onion mixture, stirring constantly to combine and cook out the raw flour taste, about 2 minutes. Then, stir in the sweet mild paprika and chopped dill, seasoning with kosher salt and cracked black pepper to taste.
- Deglaze with wine: Pour in ½ cup of dry white wine to deglaze the pot, scraping up any browned bits from the bottom. Let it simmer until the wine reduces slightly, about 3-4 minutes.
- Add broth and soy sauce: Stir in the low-sodium chicken or vegetable broth along with 2 tablespoons low-sodium soy sauce. Bring the soup to a gentle simmer and let it cook for around 10-15 minutes to meld the flavors and thicken slightly.
- Add milk and sour cream: Slowly whisk in the whole milk to maintain a smooth texture. Remove the soup from heat and gently fold in the sour cream to add creaminess and tang, ensuring it is fully incorporated without curdling.
- Season and finish: Stir in the white wine vinegar or sherry vinegar to brighten the flavors, adjust salt and pepper as needed, and add chopped fresh parsley for a fresh aroma and garnish.
- Serve warm: Ladle the creamy mushroom soup into bowls and serve immediately, perfect with crusty bread or a light salad to complement its rich texture.
