Canned soup is often watery and bland compared to homemade versions. However, there are ways to improve it. One method is to add herb-infused butter, such as oregano, tarragon, or bay leaves, to give the soup more flavor. Rosemary and thyme can also be added to brighten up chicken soup. For a Thai twist, sauté lime leaves, lemongrass, and garlic in butter, then add coconut milk. Chives, dried dill, parsley, and crème fraîche can also enhance the soup's taste.
