It's not recommended to freeze Salad Olivier because the vegetables in the salad will become waterlogged and mushy. Freezing and thawing the mayonnaise can also cause it to split. Olivier salad is best consumed soon after preparation to ensure optimal flavor and texture. If you need to store Salad Olivier, it is recommended to refrigerate it in an airtight container for up to 3-4 days instead of freezing.
