With so many dishes calling for mayonnaise, it would be handy if this ingredient could freeze, but unfortunately the answer is no. Mayo cannot be frozen because it will separate during the freezing process and will not resemble mayonnaise when done.
This means that any dips or recipes that include mayonnaise cannot be frozen. However, Miracle Whip can be frozen when you are able to substitute Miracle Whip for mayonnaise, such as in our Freezeable Ham Sandwiches.
If you are so inclined, next time you are at the end of a jar of mayo, pop it into the freezer and you can see exactly why mayonnaise is one ingredient that cannot be frozen.
