Ingredients
Scale
Soup Base
- 4 tablespoons butter
- ½ onion, diced (about 1 cup)
- 8 ounces mushrooms, sliced (about 4 cups)
Broth and Thickener
- 2 cups vegetable broth, divided
- ¼ cup all-purpose flour
- 1 teaspoon fresh thyme leaves
Finishing Touches
- 1 cup milk or heavy cream
- Salt and pepper, to taste
- Fresh parsley, chopped, for garnish
Instructions
- Sauté Vegetables: Heat butter in a large pot over medium-high heat. Add diced onions and sauté until they become tender. Next, add the sliced mushrooms and continue sautéing until they are softened and lightly browned, which enhances their flavor.
- Deglaze and Season: Pour a splash of vegetable broth into the pot and use a spoon to scrape up any browned bits stuck to the bottom. These bits add depth to the flavor. Stir in the fresh thyme leaves to infuse the soup with a subtle herb aroma.
- Make Roux: In a separate bowl, whisk together the flour and the remaining vegetable broth until you get a smooth mixture with no lumps. This will act as a thickening agent for the soup.
- Thicken Soup: Pour the flour and broth mixture into the pot with the vegetables. Bring it to a boil while stirring constantly to prevent lumps. Once boiling, reduce the heat and let it simmer for 10-15 minutes, allowing the soup to thicken to your preferred consistency.
- Add Milk or Cream: Stir in the milk or heavy cream to give the soup its signature creamy texture. Season with salt and pepper according to your taste preferences.
- Serve: Garnish the soup with freshly chopped parsley for a pop of color and freshness. Serve the soup warm and enjoy the comforting flavors.
Notes
- For a richer soup, use heavy cream instead of milk.
- You can swap vegetable broth for chicken broth if not vegan or vegetarian.
- Make sure to stir constantly when adding the flour mixture to avoid lumps.
- For a smoother texture, blend the soup before adding milk or cream.
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
