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 and potential spoilage.
Transfer the soup into airtight containers. For convenience, use portion-sized containers so you can easily reheat just the amount you need.
Label each container with the date. This ensures you keep track of how long the soup has been stored and helps maintain freshness.
Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. The cool temperature will keep the vegetables and barley fresh and flavorful.
For longer storage, place the containers in the freezer. The soup can be frozen for up to 3 months without losing its quality. Make sure to leave some space at the top of the containers, as the soup will expand when frozen.
When ready to enjoy, thaw the soup in the refrigerator overnight. This gradual thawing process helps maintain the texture and flavor of the vegetables and barley.
Reheat the soup on the stovetop over medium heat, stirring occasionally until heated through. Alternatively, you can use the microwave, heating in short intervals and stirring in between to ensure even warming.
If the soup has thickened too much after freezing, add a splash of vegetable broth or water to reach your desired consistency. Adjust the seasoning if necessary, as freezing can sometimes dull the flavors.
Enjoy your Instant Pot Vegan Vegetable and Barley Soup with a fresh slice of crusty bread or a side salad for a complete, nourishing meal.
