Instructions
Prep. Preheat the oven to 400ºF. Line a baking sheet with foil and set aside.
Roast the mushrooms. In a large mixing bowl combine mushrooms and onions with garlic, Italian Seasoning, salt, pepper, and olive oil. Toss to coat. Spread the mushrooms in a single layer on the previously prepared baking sheet. Bake for 30 minutes, or until the vegetables are roasted and tender. Remove from oven and let stand for 5 minutes.
Blend. Transfer the roasted mushrooms and onions to a blender. Add thyme leaves, parmesan cheese, and 1 cup of vegetable stock. Blend until completely smooth. (Depending on the size of your blender, you may have to blend in batches.)
Make the soup. Transfer the blended mushroom mixture to a large pot. Add the remaining vegetable stock and 1 cup of water. Stir and cook over medium-high heat until heated through. If the soup is too thick, add more vegetable broth as needed.
Finish and serve. Taste the soup for salt and pepper and adjust accordingly. Then, remove from heat and ladle the creamy mushroom soup into bowls.
