For a richer soup, use whole milk or add a touch of heavy cream at the end. To make it vegan, use vegetable broth and a plant-based milk alternative like cashew or oat milk, and thicken with a cornstarch slurry instead of flour. Consider adding roasted vegetables for deeper flavor, or blending in cooked chicken or seafood for a heartier meal. Garnish with fresh herbs, croutons, or a swirl of pesto.
