The secret to making a flavorful vegetable soup is using high quality ingredients and building flavor in steps. This recipe is incredibly flavorful because the vegetables are first sautéed to release their natural sweetness and develop a rich base. By layering flavors–from caramelizing the tomato paste to adding fresh herbs and finishing with rich Parmigiano Reggiano–each ingredient enhances the dish. The end result is a hearty vegetable orzo soup with remarkable flavor and complexity!
