This soup is a mix between the classic onion soup and the famous pumpkin soup! The sweetness of caramelized onions marries perfectly with the creamy deliciousness of butternut squash, cream, thyme, and a touch of nutmeg. For extra indulgence, I serve it with cheesy toasts. What I really want is to cozy up in my favorite spot and eat a big soul warming bowl of this. Such a treat!
