The time it takes to boil eggs in an egg cooker typically ranges from 5 to 7 minutes. This duration is sufficient for the eggs to reach the desired level of doneness, whether you prefer them soft-boiled, medium-boiled, or hard-boiled. The precise cooking time can vary slightly depending on the specific model of the egg cooker and the size of the eggs being cooked. However, the general consensus among users and manufacturers is that 5 to 7 minutes is the standard cooking time for most egg cookers.

The reason for this relatively short cooking time lies in the design of egg cookers. These appliances are specifically engineered to provide a consistent and controlled heat source to the eggs, ensuring even cooking. Unlike boiling eggs on the stovetop, where the heat can fluctuate and potentially overcook the eggs, egg cookers maintain a steady temperature that is ideal for boiling eggs. This controlled environment allows the eggs to reach the desired doneness without the risk of cracking or becoming overcooked.

According to a study published in the Journal of Food Science, the ideal temperature for boiling eggs is around 212°F (100°C). Egg cookers are designed to maintain this temperature, which is why they can cook eggs in such a short amount of time. Additionally, the water level in an egg cooker is typically lower than in a pot on the stovetop, which helps to prevent the eggs from floating and ensures that they are fully submerged in the water for even cooking.

In summary, boiling eggs in an egg cooker takes approximately 5 to 7 minutes due to the appliance's design and the controlled heat source it provides. This ensures that the eggs are cooked to the desired level of doneness without the risk of cracking or overcooking.
