Tips for Best Results
Seafood Options: Feel free to add scallops or fish chunks for more variety.
Blending: For a chunkier soup, blend only half the base and leave some vegetables intact.
Storage: Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently to avoid curdling the cream.
Enjoy this rich and flavorful seafood soup as a comforting appetizer or a hearty main course!
