When stored properly in their shells, hard-boiled eggs can last up to 1 week (7 days) in the refrigerator, according to current food safety guidelines from the USDA and FDA.
Important Storage Best Practices
To keep hard-boiled eggs fresh and safe to eat, keep these guidelines in mind:
-
Leave the Shells On: Store your hard-boiled eggs with their shells intact. The shell acts as a natural protective barrier that keeps out bacteria and prevents the egg from drying out. (Peeled hard-boiled eggs should be eaten within 1 to 2 days and stored in an airtight container with a damp paper towel).
-
Keep Them Cold: Store eggs on an inner shelf of the refrigerator rather than in the door. The temperature in the main body of the fridge remains much more stable (ideally at or below 40°F / 4°C).
-
Mark Your Batch: If you boil a large batch for meal prep, use a pencil or a piece of tape to write the boiling date on the carton so you never have to guess how long they have been sitting in there.
How to Tell If a Hard-Boiled Egg Has Gone Bad
If you are unsure whether an older egg is still safe to eat, use your senses:
-
The Smell Test: Once peeled, a spoiled egg will emit a distinct, unpleasant sulfur or ammonia-like odor. If it smells “off,” discard it immediately.
-
Texture and Appearance: If the white feels unusually slimy, sticky, or tacky, or if there is any visible mold, do not eat it.
The Bottom Line
Hard-boiled eggs make a fantastic, protein-packed snack or breakfast addition—just be sure to enjoy them within one week of boiling them.
