Recipe Information
Ingredients
- 3 tablespoons unsalted butter
- 1 tablespoon olive oil
- 3 large (thinly sliced) yellow onions
- 12 ounces (sliced) cremini mushrooms
- 3 cloves (minced) garlic
- 1 teaspoon fresh thyme
- 2 tablespoons all-purpose flour
- 4 cups chicken or vegetable stock
- 1 cup heavy cream
- 0.5 teaspoons (more to taste) salt
- 0.25 teaspoons (more to taste) ground black pepper
- 2 tablespoons (fresh, chopped, for garnish) parsley
- 4 slices (optional, for serving) crusty bread
Instructions
In a large pot or Dutch oven, heat the butter and olive oil over medium heat until the butter is melted and bubbling.
Add the sliced onions to the pot and cook, stirring occasionally, for 20-25 minutes or until they are golden brown and caramelized. Lower the heat if necessary to prevent burning.
Add the mushrooms to the pot and cook for another 8-10 minutes, stirring often, until the mushrooms are softened and their moisture has evaporated.
Stir in the minced garlic and fresh thyme, cooking for 1-2 minutes until fragrant.
Sprinkle the flour over the onion and mushroom mixture and stir well to combine. Cook for 1-2 minutes to remove the raw flour taste.
Slowly pour in the chicken or vegetable stock while stirring constantly to avoid lumps. Bring the mixture to a gentle simmer and cook for 10 minutes to allow the flavors to meld.
Using an immersion blender, carefully blend the soup until smooth and creamy. Alternatively, transfer the soup in batches to a traditional blender and blend until smooth, then return it to the pot.
Stir in the heavy cream, then season the soup with salt and ground black pepper to taste. Simmer gently for another 5 minutes, being careful not to let it boil.
Ladle the soup into bowls, garnish with fresh chopped parsley, and serve with crusty bread on the side if desired.
