How Long Does Hard-Boiled Eggs Last?

A week is the standard window for a hard-boiled egg kept in its shell and refrigerated, and that timeline shortens meaningfully once an egg is peeled — a peeled egg exposed to air and the fridge's other odors is best eaten within a couple of days rather than treated as good for the same full week as an unpeeled one.

The genuine spoilage signs to watch for are a strong sulfur or rotten smell distinct from a hard-boiled egg's normal mild egg scent, a slimy or chalky-feeling shell, or a grayish, off-color white — any of those, especially the smell, mean the egg should be discarded rather than eaten, since a spoiled egg's smell is generally unmistakable once it's actually gone bad.

The harmless gray-green ring sometimes seen around the yolk is worth distinguishing from real spoilage — it's a cosmetic reaction between iron and sulfur compounds that shows up more with a longer cook time or older starting eggs, not a sign the egg has turned, and eggs showing that ring are still safe to eat within their normal one-week window. Eggs that were already close to their own expiration date before being boiled don't gain a fresh week from the cooking process — the one-week hard-boiled window is a general guideline assuming reasonably fresh eggs to begin with, not a reset clock independent of how old the raw eggs already were.
