Hard-boiled eggs are handy to have on hand for a snack, a salad topping or to use in recipes. They will last about one week (seven days) in the refrigerator, either peeled or unpeeled. Hard-boiled eggs are ideally kept in their shell until ready to use.
Make sure you refrigerate eggs at 45°F or colder and do not freeze.
Store in Water
Hard-boiled, peeled eggs may be stored in the fridge, in a bowl of cold water. Make sure the eggs are completely submerged and change the water often--at least daily--to discourage bacterial growth.
You can also cover your hard-boiled eggs with damp paper towels and store in a container with a tight lid.
Try not to leave hard-boiled eggs, especially peeled ones, at room temperature for too long. Hard-boiled eggs on a buffet, peeled or unpeeled, should be kept over ice. If you are ever in doubt about an egg's safety, dispose of it.
For best quality, your eggs should really be used within a few days of cooking. Peeled hard-boiled eggs can create an unpleasant odor in your refrigerator if kept uncovered. They can also pick up odors from strong-smelling foods.
