Egg whites generally last about 2–4 days in the fridge when stored properly in a clean, airtight container at or below 40°F (4°C). For longer storage, they can be frozen and kept for several months to a year, depending on the source and conditions.

Fridge shelf life

  • Raw egg whites kept in a sealed container in the main part of the fridge (not the door) are typically safe for up to 4 days.
  • Many food safety and egg industry guides list “up to 4 days” as the standard for raw separated whites under proper refrigeration.
  • Using them within 2–3 days gives the best texture for baking (like meringues or pavlova) and reduces risk further.

Freezer option

  • Egg whites can be frozen if you need to keep them longer; multiple sources note they can stay good for months , often up to about a year when well sealed.
  • Common methods include freezing them in portions (like ice cube trays) and then transferring to a freezer bag, which makes it easy to defrost only what you need.

Signs they’ve gone bad

  • Discard egg whites if you notice an off or sulfur-like smell, unusual color (pink, green, cloudy with streaks), or a very runny, watery texture that looks different from when you stored them.
  • When in doubt—especially if you’re unsure how long they’ve been in the fridge—it is safer to throw them out than risk a foodborne illness.

Quick usage tips

  • For best safety, label your container with the date you separated the whites so you know when the 2–4 day window ends.
  • For bulk baking or meal prep, freezing extra whites right away instead of letting them sit in the fridge can help minimize waste and keep them ready for later recipes like meringues, omelets, or protein add-ins.

TL;DR: In the fridge: 2–4 days max in an airtight container. For long- term storage: freeze and use within a few months to about a year, depending on quality and how well they’re packed.
