Set a timer and wait
The amount of time your eggs need to cook depends on how you want them done. If you want soft-boiled eggs, which will have a runny yolk, set your timer for 3 minutes. If you want medium boiled eggs, set your timer for 6 minutes. For a perfect hard-boiled egg, set your timer for at least 10 minutes. Everyone prefers their boiled eggs cooked differently. Once you’ve practiced a few times, you’ll figure out the perfect amount of cooking time for your tastes.
