Starting the eggs in cold water and bringing them to a boil before covering and killing the heat cooks the whites evenly without the rubbery texture or greenish yolk ring that comes from a hard, prolonged boil, and a quick ice bath afterward shrinks the egg away from the shell so it peels cleanly.

Instructions

1Place the eggs in a single layer in a medium saucepan and add enough cold water to cover them by about 1 inch.
2Bring the water to a full, rolling boil over high heat, uncovered.
3As soon as the water reaches a boil, remove the pan from the heat, cover it, and let the eggs sit in the hot water for 10 to 12 minutes (10 minutes for a slightly soft-set yolk, 12 for fully firm).
4While the eggs sit, fill a large bowl with ice water.
5Using a slotted spoon, transfer the eggs directly from the pot into the ice bath and let them cool for at least 5 minutes.
6Tap each cooled egg gently on the counter to crack the shell all over, then peel under a thin stream of running water, starting at the wider end where the air pocket sits.

How to Tell If Eggs Are Still Good

Tips & variations

Eggs that are a week or two past their pack date often peel more easily than very fresh ones, since the egg white's pH rises slightly as it ages, which loosens its grip on the shell membrane. Very fresh eggs (just laid or bought that week) are notoriously hard to peel cleanly.
Adding a teaspoon of baking soda to the boiling water raises the pH of the cooking water slightly and can also help fresher eggs release from the shell more easily.
For a dozen eggs, use a wider pot so they still sit in a single layer; stacking eggs leads to uneven cooking.
Steaming works as an alternative to boiling: set eggs in a steamer basket over an inch of boiling water, cover, and steam for 12 to 13 minutes, then move straight to the ice bath.

Storage & reheating

Keep hard-boiled eggs in their shells if not eating right away; the shell protects the egg and keeps it fresher longer than peeling ahead of time. Refrigerated in the shell, they keep for up to 1 week; peeled eggs should be stored in a covered container, ideally with a damp paper towel, and used within 3 to 4 days. Hard-boiled eggs are eaten cold or at room temperature, not really reheated, but if a warm egg is wanted, submerge the unpeeled egg in a bowl of hot (not boiling) water for about 10 minutes. Don't freeze whole hard-boiled eggs; the whites turn rubbery and watery as they thaw.

Tips from the Tulo kitchen

The date on an egg carton (a 'sell-by' or 'pack' date) is not an expiration date; eggs stored continuously below 40°F (4°C) are typically safe to eat for 3 to 5 weeks after that date, not just until it passes.
A quick float test settles most doubts: submerge a raw egg in a bowl of water. It lies flat on its side if very fresh, stands upright if getting older but still fine, and floats to the top if it should be tossed, since air has replaced enough of the moisture inside the shell.

FAQ

Do eggs go out of date?

Eggs don't have a hard expiration date the way some perishables do. The date stamped on the carton (often labeled 'sell-by' or 'pack date') refers to when the eggs were packed or should leave the store shelf, not when they become unsafe. As long as they've been refrigerated continuously at or below 40°F (4°C), raw eggs are generally safe for 3 to 5 weeks past that date, and hard-boiled eggs are good for about 1 week after cooking.

How can I tell if an egg has actually gone bad?

Crack it into a bowl first and check for an off, sulfurous smell, which is the clearest sign of spoilage. Visually, a pink, green, or black tint, or an unusually runny white, are also red flags. The float test in cold water is a reliable check before cracking: an egg that floats has too much internal air and should be discarded.

How long do hard-boiled eggs last in the fridge?

Up to 1 week when left unpeeled and refrigerated. Once peeled, use them within 3 to 4 days and store them in a sealed container so they don't absorb odors from other fridge items.

Why did the yolk turn a greenish-gray color?

That ring forms when eggs are boiled too long or at too high a heat. Iron in the yolk reacts with hydrogen sulfide released from the white, forming a harmless but unappetizing greenish film. Pulling the eggs off the heat right at 10 to 12 minutes and chilling them immediately prevents it.
