Place the oranges, pineapple, coconut and marshmallows in a large bowl. Add the Cool Whip and, using a rubber spatula, gently fold the mixture until all of the ingredients are evenly distributed.
Cover and refrigerate until ready to serve. Ambrosia can be stored in the refrigerator for up to 3 days.
Notes
Fruit Options: Fresh orange segments, maraschino cherries, bananas, strawberries, grapes, or canned fruit cocktail.
Dressing Options: Pudding, cream cheese, yogurt, sour cream, or Jello.
Freezing Instructions: I only recommend freezing ambrosia if you use all canned fruit and Cool Whip. Using fresh fruit and/or homemade whipped cream can cause it to be soggy and watery when thawed.
Make-Ahead: This can be mixed together and refrigerated the day before serving.
Storage: Ambrosia can be stored in the refrigerator for up to 3 days.
