How Can I Tell If an Egg Is Hard-Boiled Without Breaking It?

by Nick Marshall

Telling the difference among raw, soft boiled and hard boiled can be as easy as knowing a few tricks. Read on to find out when your eggs are done.

Hard-Boiled or Raw?

Place the egg on its side on a smooth countertop, away from obstructions.

Spin the egg gently. A hard-boiled egg, being solid, will spin smoothly. A raw egg, being liquid inside, will wobble.

Double-check by spinning the egg and suddenly stopping its rotation with the tip of your finger. A hard-boiled egg comes to an immediate stop and stays stopped if you lift your finger. A raw egg begins to rotate again, though more slowly, if you quickly lift your finger away from the egg.

Hard or Soft-Boiled?

Place eggs in a pan, just covered by cold water.

Bring to a rolling boil for one minute.

Remove the egg from the water it is boiling in with a slotted spoon. A hard-boiled egg, containing greater residual heat, dries in about 10 seconds, while a soft-boiled egg stays wet for up to 20 seconds.

Items you will need
  • Slotted spoon
  • Pot for boiling water

Warnings

  • Spin eggs away from the countertop, as they can easily veer off course and plummet to the ground.
  • Hard-boiled eggs spoil more quickly than raw eggs. Store them in their shells in the fridge after cooking, if necessary, but discard after a week.
