How To Cook a Perfect Soft-Boiled Egg


How To Cook a Perfect Soft-Boiled Egg is not a recipe, it is more of a cooking method that is too good not to share. The  American test kitchen tested about 1000 eggs to perfect the cooking method of a soft-boiled egg.



The perfect soft-boiled egg has a firm egg white and soft egg yolk.  Whenever I use the American test kitchen cooking method, my soft-boiled eggs are a home run and cooked to perfection.
The whites of an egg are set at 180 degrees F (82 degrees C), while the yolk will cook through if it gets past 158 degrees F (70 degrees C). Using only a ½ inch of water, the steam coming off the water is a regular, constant 212 degrees F (100 degrees C), allowing the eggs to cook quickly, without giving the yolk time to set up.

Be sure to use large eggs that have no cracks and are cold from the refrigerator.
Because precise timing is vital to the success of this cooking method, it is strongly recommended to use a digital timer.

  1. Wow! I eat softboiled eggs a lot and I was totally SKEPTICAL about this procedure. IT WORKS! I’ll never cook ’em any other way.

    Got any tips for cooking (say) a dozen or two at once?

      Ed, Thanks for the feedback. I don’t think it would be a problem cooking a dozen eggs using that method. However, if you need to cook more, I think it might require a bit more water.
      I haven’t personally tried it for larger quantities.”
