Boiling eggs with an egg cooker typically takes approximately 8 to 10 minutes. This time frame is based on the standard boiling temperature of water, which is around 212°F (100°C). Egg cookers are designed to maintain a consistent temperature, ensuring that the eggs are cooked evenly. The precise timing can vary slightly depending on the model of the egg cooker and the desired level of doneness. For example, if you prefer your eggs to be soft-boiled, you may need to reduce the cooking time to around 6 to 7 minutes. Conversely, for hard-boiled eggs, extending the cooking time to 10 to 12 minutes is recommended. The data supporting these guidelines comes from various kitchen appliances and cooking resource websites, which provide detailed instructions and cooking times for different types of egg cookers.
