how long to hard boil an egg

For a classic hard-boiled egg with a fully set yolk and firm white, keep large eggs in boiling water for about 10–12 minutes.

Basic timing (large eggs)

These times assume you gently lower cold eggs into already boiling water, then start your timer:

• 8 minutes: Mostly set yolk, still a bit creamy in the center.
• 10 minutes: Fully set yolk, not dry or chalky (sweet spot for most people).
• 12 minutes: Very firm yolk, closer to “old-school” hard-boiled.

If you prefer to use the “turn off the heat and cover” method, let the eggs sit in the hot water about 10–12 minutes as well, then chill.

Step‑by‑step method

1. Place eggs in a single layer in a pot and cover with about 2.5 cm of water.
2. Bring the water to a full boil over medium‑high heat.
3. Start your timer as soon as it boils. Boil for 10–12 minutes for hard‑boiled.
4. Transfer eggs immediately to an ice‑water bath and cool at least 10–15 minutes.
5. Peel under running water for easier shell removal.

Little variables that change the time

• Egg size: Medium may need 1 minute less, extra‑large 1–2 minutes more.
• Starting temperature: Fridge‑cold eggs can need about 1 minute more than room‑temperature.
• Stove and pot: Thin pots or very strong burners may cook a bit faster, so note what works in your kitchen.

Quick rule of thumb: Start at 10 minutes for hard‑boiled, then adjust by 1 minute up or down next time if you want a creamier or firmer yolk.
