How to Hard Boil an Egg Perfectly

Nothing is much easier than hard boiling an egg. Cook eggs slowly so the boiling water does not bounce them around and break the shell. A  properly cooked egg is solid but not rubbery, and it should be easy to peel. Over cook an egg and you get a dark green ring around the yolk. The green discoloration is harmless,  caused by the  iron and sulfur from the yolk and white coming in contact, and cooking too long.

To hard cook an egg:

  • Bring the water to a boil
  • Place the eggs in the water using a tablespoon to set them in softly, reduce heat so the water boils gently not at a rolling boil. Use enough water to cover the eggs completely.
  • To hard cook an egg can take 10 to 20 minutes depending on the number of eggs being cooked and the temperature of the raw eggs before cooking.


Knowing when an egg is cooked to desired hardness is tricky, for that reason I use an egg timer.

Simply place the eggs timer in with the eggs and water, bring to a boil as you normally would. When the color changes from red to purple and reaches the desired spot on the scale you wish:  soft, medium or hard, you will have the perfect egg,  cooked just the way you like it. You can find an egg timer at any good kitchen store or go to one of the links listed below.

    I just got one … I was not aware of this trick. Thanks for writing about it.
    My trick was … boil the water, place the eggs in the water, and go watch discovery. 7-9 minutes after, the water will evaporate and the fire alarm will start beeping… TIME TO CHECK THE EGGS :)
