This herbed mushroom soup is bursting with fresh flavors. Start by sautéing onions and garlic in butter until fragrant. Add sliced mushrooms and cook until they release their moisture. Stir in vegetable or chicken broth, thyme, rosemary, and a bay leaf. Simmer for about 20 minutes to let the flavors infuse. Remove the bay leaf, then blend the soup until smooth. Season with salt and pepper, and garnish with fresh herbs like parsley, chives, or dill.
