Frequently Asked Questions

Everything people ask about boiling eggs — timing, egg size, altitude, peeling, the green yolk ring and storage. For the full method in one place, see the egg cooking time guide.

Questions

Timing

How long do you boil an egg for it to be hard boiled?

Twelve minutes at a rolling boil for a large egg. Small eggs need about 10 minutes 30 seconds, extra large about 13 minutes.

How many minutes for a soft boiled egg?

Six minutes at a rolling boil for a large egg, giving a fully set white and a warm, runny yolk.

How many minutes for a jammy or medium boiled egg?

Eight minutes at a rolling boil for a large egg. Pull at 7 minutes 30 seconds for a wetter centre.

Do you start timing before or after the water boils?

After. Bring the water to a full rolling boil, lower the eggs in gently, then start the timer.

Do you put eggs in boiling water or cold water?

Boiling water, if you want repeatable results. A cold water start is gentler on the shells but the total time shifts with your pot and stove.

Questions

Egg variables

Does egg size change the boiling time?

Yes, by roughly 30 seconds per size step. At the soft boiled end that is the difference between a liquid yolk and a setting one.

How long to boil eggs at high altitude?

Add about 1 minute per 3,000 feet of elevation. Water boils cooler as you go up, so the egg cooks more slowly even at a full boil.

Should eggs be at room temperature before boiling?

Not necessarily. These times assume cold eggs from the fridge. Room temperature eggs finish about 30 seconds sooner and crack slightly less often.

How long to boil quail eggs?

Two to three minutes for soft, about four and a half for hard. Far shorter than chicken eggs.

Questions

Troubleshooting

Why does my hard boiled egg have a green ring around the yolk?

It is iron sulfide, a harmless reaction between sulfur in the white and iron in the yolk that happens when eggs are overcooked or cooled too slowly.

How do I make eggs easier to peel?

Use eggs 7 to 10 days old rather than very fresh, chill them in ice water for at least 10 minutes, and peel from the fat end under cool running water.

Why do my eggs crack when boiling?

Usually thermal shock from cold eggs hitting boiling water, or eggs knocking together in a violent boil. A pin-prick in the fat end and a steadier boil both help.

My egg is undercooked, can I put it back?

Yes. Return it to boiling water for another minute or two. It will not be quite as even as an egg cooked straight through, but it is perfectly good.

Why is my egg white rubbery?

Overcooking. The white firms up long before the yolk does, so extended boiling toughens it.

Questions

After cooking

How long do hard boiled eggs last in the fridge?

About one week, whether peeled or unpeeled, as long as they were refrigerated within two hours of cooking.

Can you freeze hard boiled eggs?

Not successfully as whole eggs. Both white and yolk turn tough and watery on thawing.

How can you tell if an egg is boiled or raw?

Spin it on a flat surface. A boiled egg spins smoothly because the contents are solid; a raw one wobbles.

How long should eggs sit in an ice bath?

Two to three minutes for soft boiled, at least five for medium, and ten or more for hard boiled if you want the easiest peeling.
