Fill a medium saucepan 3/4 full of water. Bring the water to boil.
Use a large slotted spoon to lower the eggs, one by one, into the boiling water. Reduce the heat just a touch to prevent the eggs from knocking against each other.
Cook for 12 minutes for hard-cooked. Reduce the cooking time by 2 minute increments for softer cooked results; cook for 6 minutes for a soft, runny center. Cook for 8 minutes for medium-cooked eggs.
Fill a medium bowl halfway with ice and cool water. Remove the pot from the heat and with a slotted spoon transfer the eggs to the ice bath. Allow them to rest for 2 minutes.
Crack the eggs on a hard surface and peel them under a cool running faucet. Slice and serve.
Notes
For easier peeling, use slightly older eggs rather than very fresh ones.Storage: Hard-boiled eggs will stay fresh in an airtight container in the fridge for up to 1 week, medium-boiled eggs last for about 5 days, and soft-boiled eggs will keep for up to 3 days.
