Slow Cooker Creamy Mushroom Soup
This recipe creates a smooth and flavorful creamy mushroom soup perfect for a cozy meal. The slow cooker allows the mushrooms to release their deep umami flavor for a rich and satisfying soup.
Ingredients:
- 2 tablespoons olive oil
- 1 pound cremini mushrooms, sliced
- 1 yellow onion, diced
- 4 cloves garlic, minced
- 4 cups vegetable broth
- 1/2 cup dry white wine (optional)
- 1 tablespoon chopped fresh thyme
- 1 bay leaf
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 cup heavy cream
- 2 tablespoons cornstarch
- Chopped fresh parsley (for garnish, optional)
Cooking Guide:
- Heat olive oil in a large skillet over medium heat. Add the sliced mushrooms and cook for 5-7 minutes, until softened and lightly browned.
- Add the diced onion and garlic to the skillet and cook for an additional 2-3 minutes, until softened and fragrant.
- Transfer the mushroom mixture to your slow cooker. Add vegetable broth, white wine (if using), thyme, bay leaf, salt, and pepper. Stir to combine.
- Cover the slow cooker and cook on LOW for 4-6 hours, or on HIGH for 2-3 hours, until the mushrooms are very tender.
- Remove the bay leaf. Using an immersion blender, blend the soup until smooth, or transfer the soup to batches in a blender and blend until smooth. Return the blended soup to the slow cooker.
- In a small bowl, whisk together the heavy cream and cornstarch to form a slurry. Slowly whisk the slurry into the slow cooker and cook on LOW for an additional 15 minutes, or until slightly thickened.
- Taste and adjust seasonings with additional salt and pepper if desired.
- Serve hot, garnished with chopped fresh parsley (optional).
Tips:
- For a richer flavor, use a combination of cremini mushrooms and portobello mushrooms.
- If you don’t have dry white wine, you can substitute it with an equal amount of additional vegetable broth.
- You can add a splash of sherry or brandy for a deeper flavor profile.
- To make the soup vegan, use vegan butter or olive oil and substitute the heavy cream with a can of full-fat coconut milk.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
