Now, let’s dive into the heart of our topic: how long do eggs last? The shelf life of eggs varies depending on several factors, including storage conditions and their expiration date.

  • Refrigerated Eggs: When stored in the refrigerator at a consistent temperature of 40°F (4°C) or below, eggs can last up to 3-5 weeks past their pack date. It’s essential to store eggs in their original carton to protect them from absorbing odors and flavors from other foods in the fridge.
  • Room Temperature Eggs: Eggs should not be kept at room temperature for more than 2 hours. If left out longer, they should be discarded to prevent the risk of bacterial contamination.
  • Freshness Test: To determine the freshness of an egg, you can perform a straightforward float test. Place the egg in a bowl of water; if it sinks and lies flat on the bottom, it’s fresh. If it stands on one end at the bottom, it’s still good but should be used soon. If it floats, it’s best to discard it.
  • Check the Expiration Date: Always check the expiration or “sell by” date on the egg carton. While eggs can often be consumed safely after this date, it’s a good guideline to follow for optimal freshness and quality.

Understanding how to store eggs properly and being mindful of their shelf life is crucial for enjoying them safely and getting the best flavor and texture in your dishes. Whether you’re preparing a complex recipe like Vietnamese Braised Pork and Eggs or opting for a quick and easy Sheet Pan Eggs breakfast, ensuring your eggs are fresh and properly stored is paramount.
