How long does it take eggs to boil hard?
Cover the eggs in a saucepan with water. Bring the water to a full rolling boil. Turn OFF the heat, keep the pan on the hot burner, cover, and let sit for 10-12 minutes. Strain the water from the pan and run cold water over the eggs to cool them quickly and stop them from cooking further.
Place eggs in pan, add water to cover the eggs by about 1 inch. Bring to a boil over medium high heat then time from 5 - 12 minutes depending on your preference of softer to harder hard boiled eggs. Take from boiling water and place into ice water peeling one by one immediately after the ice water.
