This hearty and nutritious vegetable and barley soup is perfect for a cozy meal. Made entirely in the Instant Pot, it’s a quick and easy way to enjoy a warm bowl of goodness. Packed with carrots, celery, onions, and barley, this vegan soup is both filling and flavorful.
Most of the ingredients in this recipe are common pantry staples, but you might need to pick up barley if you don't already have it. Barley is a nutritious whole grain that adds a delightful chewiness to the soup. You can find it in the grain or cereal aisle of most supermarkets. Make sure to get vegetable broth as well, which is essential for the soup's base.

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 cooled soup into airtight containers. For easy portion control, consider using individual serving-sized containers.
Label each container with the date. This ensures you can keep track of how long the soup has been stored.
Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. This keeps the vegetables fresh and the barley from becoming too mushy.
For longer storage, place the containers in the freezer. The soup can be frozen for up to 3 months without losing its flavor and texture.
When ready to enjoy, thaw the soup in the refrigerator overnight. This gradual thawing process helps maintain the integrity of the vegetables and barley.
Reheat the soup on the stovetop over medium heat, stirring occasionally. Add a splash of vegetable broth if the soup has thickened too much during storage.
Alternatively, you can reheat the soup in the microwave. Use a microwave-safe bowl, cover loosely, and heat in 1-2 minute intervals, stirring in between, until hot.
Adjust the seasoning after reheating. Sometimes, soups can lose a bit of their seasoning punch after being stored, so a pinch of salt or pepper might be needed.
How to Reheat Leftovers
To reheat your leftover Instant Pot Vegan Vegetable and Barley Soup, start by transferring the desired amount to a saucepan. Heat over medium heat, stirring occasionally, until the soup is thoroughly warmed. This method helps maintain the texture of the barley and vegetables.
Alternatively, you can use a microwave. Place the soup in a microwave-safe bowl and cover it with a microwave-safe lid or a plate to prevent splatters. Heat on high for 2-3 minutes, stirring halfway through to ensure even heating. Adjust the time as needed based on your microwave's power.
For a quick and efficient method, you can reheat the soup directly in the Instant Pot. Pour the soup back into the pot, set it to the sauté mode, and stir occasionally until the soup is hot. This method is perfect for reheating larger quantities.
If you prefer a slow and gentle reheating process, use a slow cooker. Transfer the soup to the slow cooker and set it on low for 1-2 hours, or until the soup is heated through. This method is ideal for maintaining the soup's flavors and textures.
For a creative twist, consider reheating the soup and then blending it partially with an immersion blender to create a thicker, creamier texture. This can give a new dimension to your leftover soup.
