For a richer flavor, consider sautéing the vegetables in a tablespoon of olive oil before adding the broth. If you prefer a completely smooth soup, blend the entire batch before serving. To add a smoky depth, incorporate a teaspoon of smoked paprika along with the regular paprika. This soup is even better the next day, as the flavors meld together beautifully. Store leftovers in an airtight container in the refrigerator for up to 3 days.
