For an even smoother creamy broccoli soup, blend the vegetables completely before adding the pasta.
You can replace ditalini with another small pasta shape. If the soup becomes too thick as the pasta cooks, simply add a splash of hot vegetable stock or water.
Serve with warm crusty bread, toasted pita, a simple green salad, or roasted vegetables for a more complete meal.
For a milder family-friendly version, reduce or omit the red chili flakes.
