How to Store or Freeze This Recipe
Allow the lentil soup to cool completely before storing. This helps maintain the texture and flavor of the vegetables and lentils.
Transfer the cooled soup into airtight containers. For easy portioning, consider using individual serving-sized containers. This makes it convenient to grab a single serving without defrosting the entire batch.
Label the containers with the date of preparation. This ensures you keep track of freshness and consume the soup within a safe timeframe.
Store the containers in the refrigerator if you plan to consume the soup within 4-5 days. The flavors will meld together beautifully, making the soup even more delicious.
For longer storage, place the containers in the freezer. The lentil soup can be frozen for up to 3 months without losing its hearty flavor and comforting texture.
When ready to enjoy, thaw the soup in the refrigerator overnight if frozen. This gradual thawing helps maintain the integrity of the vegetables and lentils.
Reheat the soup on the stovetop over medium heat, stirring occasionally until heated through. Alternatively, you can use the microwave, heating in 1-2 minute intervals and stirring in between to ensure even heating.
If the soup thickens too much after storing, add a splash of vegetable broth or water while reheating to reach your desired consistency. Adjust the seasoning if needed to refresh the flavors.
