The shelf life of a hard-boiled egg depends on whether it is unopened or opened and how it is stored in the refrigerator.
Unopened hard-boiled eggs: If the hard-boiled eggs are left unpeeled and kept in the refrigerator, they can last for about one week. It's important to store them in a sealed container or covered to prevent odors from affecting the eggs and to reduce moisture loss.
Opened hard-boiled eggs: Once you've peeled the hard-boiled eggs, their shelf life decreases significantly. After peeling, they should be consumed within one to two days for the best quality and safety. When eggs are peeled, they are more exposed to bacteria and moisture, which can lead to faster spoilage.
Always use your best judgment when assessing the quality and safety of any food item. If there are any signs of spoilage, such as a foul odor, sliminess, or unusual texture, it's best to discard the eggs to avoid the risk of foodborne illness.
