- For longer storage, place the airtight containers in the freezer. The soup can be frozen for up to 3 months without losing its vibrant taste and texture.
- When ready to enjoy, thaw the soup in the refrigerator overnight. This gradual thawing process helps maintain the integrity of the bell peppers and other ingredients.
