What To Do With Leftover Egg Whites (Quick Scoop)

Leftover egg whites are incredibly useful: they can be stored, frozen, and turned into desserts, breakfasts, and even savory snacks instead of going to waste.

Safe storage first

  • Keep egg whites in a clean, airtight container in the fridge for about 3 days before using.
  • For longer storage, freeze them in an ice cube tray or small portions, then transfer to a freezer bag and label the number of whites on the bag.
  • Thaw in the fridge overnight and use in cooked recipes or for baking that doesn’t rely on super-delicate foams if they’ve been frozen.
