How to store this soup

Storing your delicious Low Carb Zucchini Soup is a breeze! Here’s how:

  1. Refrigeration: If you plan to enjoy the soup within a few days, let it cool to room temperature. Transfer it to airtight containers or resealable plastic bags. Label the containers with the date for reference. Store in the refrigerator for up to 3-4 days.
  2. Freezing: To extend its shelf life, consider freezing the soup. Allow the soup to cool completely before transferring it to freezer-safe containers or resealable freezer bags. Leave some space at the top to account for expansion. Label with the date and freeze for up to 2-3 months.
  3. Individual Portions: If you prefer, portion out the soup into single servings before storing. This makes it easy to defrost and reheat only what you need.
  4. Defrosting: When you’re ready to enjoy the soup, move it from the freezer to the refrigerator to thaw overnight. Alternatively, you can thaw it in the microwave using the defrost setting.
  5. Reheating: For reheating, use the stovetop or microwave. On the stovetop, gently heat the soup over medium-low heat, stirring occasionally. In the microwave, use short bursts of heating and stir in between to ensure even reheating.
  6. Additional Seasoning: Sometimes, soups can lose a bit of flavor during freezing. Consider tasting and adjusting the seasoning after reheating. You might want to add a pinch of salt, herbs, or spices to revive the flavors.

Remember, while reheating frozen soup, make sure it’s heated through to a safe internal temperature (165°F or 74°C) to ensure that any potential bacteria are eliminated. With these storage tips, you can savor this Low Carb Zucchini Soup even on the busiest of days!
