A hard-boiled egg usually takes about 9–12 minutes of cooking time once the water is boiling, plus a few extra minutes to heat the water and cool the eggs afterward.

Quick Scoop

Super short answer

  • From boiling water: 9–12 minutes for hard-boiled yolks.
  • Total “start to finish” (heat up + cook + cool): roughly 20–25 minutes.

Basic timing guide

Most home methods fall into two main styles.

  1. Starting in boiling water
    • Gently lower eggs into already boiling water.
 * 9–11 minutes gives a fully set yolk without being super chalky.

 * Then move eggs to an ice bath for about 10 minutes so they stop cooking and peel easier.
  1. Starting in cold water, then standing
    • Put eggs in a pot, cover with cold water by about 1 inch, bring to a boil.
 * When it just boils, turn off the heat, cover, and let stand in the hot water 10–12 minutes for large eggs.

 * Cool eggs in ice water for about 10–15 minutes.

Example timing chart (yolk doneness)

These are typical ranges once the water is boiling or once you’ve turned the heat off, depending on method.

Yolk style| Approx. time (minutes)| Notes
---|---|---
Soft / jammy| 7–9 minutes| Center still creamy. 12910
Fully hard| 9–11 minutes| Solid but not over-dry. 2910
Very firm/traditional| 12–14 minutes| Classic “hard-boiled”, risk of slightly chalkier yolk. 13510

Small real-life example

If you start with fridge-cold large eggs and cold water:

  1. 5–7 minutes to bring the pot to a full boil.
  1. 10–12 minutes sitting in the hot water for hard-boiled yolks.
  1. 10–15 minutes in an ice bath so they cool and peel well.

That puts you at about 25–30 minutes from “out of the fridge” to “ready to eat,” though the actual cook phase for a hard-boiled egg is still around 9–12 minutes.

TL;DR: Plan ~10 minutes of cook time for hard-boiled, and around 20–25 minutes total including heating and cooling.
