How to Store or Freeze This Soup
Allow the soup to cool completely before storing. This helps prevent condensation, which can lead to a watery texture.
Transfer the soup to an airtight container. Glass containers with tight-fitting lids are ideal, but BPA-free plastic containers work well too.
For short-term storage, place the container in the refrigerator. The soup will stay fresh for up to 4-5 days.
For long-term storage, consider freezing the soup. Portion the soup into individual servings using freezer-safe containers or heavy-duty freezer bags. This makes it easier to thaw only what you need.
Label each container or bag with the date and contents. This helps you keep track of how long the soup has been stored.
When ready to use, thaw the soup in the refrigerator overnight. For a quicker option, place the container in a bowl of cold water to speed up the thawing process.
Reheat the soup gently on the stovetop over medium heat, stirring occasionally. If the soup is too thick after reheating, add a splash of vegetable broth or water to reach the desired consistency.
Avoid reheating the soup multiple times, as this can affect the flavor and texture. Only reheat the amount you plan to consume.
For an added burst of freshness, garnish the reheated soup with freshly chopped herbs like cilantro or parsley before serving.
How to Reheat Leftovers
For stovetop reheating:
- Pour the leftover soup into a saucepan.
- Heat over medium-low heat, stirring occasionally to ensure even heating.

For microwave reheating:

- Cover the bowl with a microwave-safe lid or plastic wrap, leaving a small gap for steam to escape.

- Check the temperature and heat in additional 30-second intervals if needed until hot.
For oven reheating:
- Preheat your oven to 350°F (175°C).
- Pour the soup into an oven-safe dish and cover with foil.
- Heat for about 20-25 minutes, or until the soup is hot throughout.
- Stir before serving to ensure even temperature.
For slow cooker reheating:
- Transfer the soup to your slow cooker.
- Set to low heat and cover.
- Heat for 1-2 hours, stirring occasionally, until the soup is hot.
For double boiler reheating:
