Add the potato salad to a freezer baggie. Do not fill it completely. Only fill it 3/4 the way full.
Squeeze all of the air out of the baggie.
Place the baggie in the freezer. Lay it flat so that the potato salad freezes flat.
To Defrost the potato salad:
1. Remove the potato salad from the freezer and place it in the fridge.
2. Allow it to defrost for 24 hours in the fridge.
3. Stir it prior to serving.
Notes
Experts advise against freezing potato salad because when you defrost it, it may be watery. If we have a lot of leftover potato salad it is worth the risk for us. Give it a try and use your own judgement on the issue.
