For hard boiled eggs, once the water reaches a rolling boil, you should turn off the heat, cover the pot, and let the eggs sit in the hot water for about 10 to 12 minutes. Ten minutes provides a creamy, vibrant yolk while 12 minutes yields a fully hard boiled yolk that is paler and chalkier. After this, place the eggs in an ice bath to cool before peeling. This method ensures the eggs are perfectly cooked without overcooking or dryness.

Different sources largely agree on this timing, though slight variations may depend on egg size and altitude, but 10-12 minutes is the standard recommendation for hard boiled eggs.
