10 to 15 minutes.
Cook for a further minute if you like your soft boiled eggs a little firmer. For a hard-boiled egg, start the egg in cold water and bring up to the boil. Once the water is gently boiling, set the timer for between 7-10 minutes depending on how well cooked you like your eggs. The longer you boil the egg, the firmer it will be. Step 1: Place the Eggs in a Pan of Water and Bring to a Boil. For hard-boiled eggs, put the eggs in a pan and cover them with cold water. This way you'll have less of a chance of breaking them. Bring to a boil, put a lid on it and turn off the heat. Let it stand for 10 to 15 minutes.  If you need easy-to-peel eggs and you have fresh eggs, you might want to try steaming the eggs for 15 minutes. Pour an inch of water into a pot and insert a steamer basket.Bring to a boil. Place the eggs in the steamer basket, cover and steam for 15 minutes (more or less, check!). Heat the pot on high heat and bring the water to a full rolling boil. Adding a teaspoon of vinegar to the water may help keep egg whites from running out if an egg does crack while cooking. Also some people find adding 1/2 teaspoon of salt to the water helps prevent cracking as well as making the eggs easier to peel. Gently lower the eggs into the water one at a time. Cook the eggs for 5 to 7 minutes: For 1 to 2 eggs, cook 5 minutes for a very runny yolk or up to 7 minutes for a barely-set yolk. For 3 or 4 eggs, add a few extra seconds to your timing. (For more than 4 eggs, cook in batches.) Remove the eggs with a slotted spoon. 1 Cook the eggs for 5 to 7 minutes: For 1 to 2 eggs, cook 5 minutes for a very runny yolk or up to 7 minutes for a barely-set yolk. 2  For 3 or 4 eggs, add a few extra seconds to your timing. ( 3 For more than 4 eggs, cook in batches.). 4  Remove the eggs with a slotted spoon. 1 Fill pot with water to completely cover the eggs at least 1 inch above eggs and turn heat to high. 2  Bring water to a boil, takes approximately 15 minutes. 3  As soon as eggs start to boil, let boil for 10-12 minutes (I do 11 minutes). 4  Set timer to help. Place the eggs with water over high heat and bring to a boil. For our gas stove, bringing the eggs to a boil takes about 15 minutes in our larger saucepan. When boiling starts, set a timer to 11 min. Depending on how cooked you like your hard boiled eggs, the eggs should be done perfectly in 10-12 minutes. That said, depending on your altitude, the shape of the pan, the size of the eggs, the ratio of water to eggs, it can take a few minutes more. Heat the pot on high heat and bring the water to a full rolling boil. Adding a teaspoon of vinegar to the water may help keep egg whites from running out if an egg does crack while cooking. Also some people find adding 1/2 teaspoon of salt to the water helps prevent cracking as well as making the eggs easier to peel. As soon as the water reaches a rapid boil, remove pan from heat and cover egg pan tightly with a lid. Set timer for 17 minutes for large eggs or 20 minutes for jumbo eggs. After 17 or 20 minutes (depending on size of your eggs), remove lid and drain off water from the eggs. Hard-cooked eggs in the shell can be refrigerated up to one week. Peeled hard boiled eggs can be stored in the refrigerator in a bowl of cold water to cover for about 1 week (change the water daily) - or in a sealed container without water (cover the eggs with damp paper towels) for the same length of time. Directions. Place eggs in a large saucepan. Cover them with cool water by 1 inch. Slowly bring water to a boil over medium heat; when the water has reached a boil, cover and remove from heat. Let sit 12 minutes. Transfer eggs to a colander; place under cool running water to stop the cooking. Eggs can be peeled and served immediately. Bring a pot of water to a boil over high heat. Reduce the heat to low, then add your eggs and cook 4 to 5 minutes. Drain, cool in ice water and peel. Medium: Bring a pot of water to a boil over high heat. Reduce the heat to low, then add your eggs and cook 7 to 8 minutes. Drain, cool in ice water and peel. Hard: Place your eggs in a pot and cover with cold water by 1 inch. Bring to a boil over medium-high heat, then cover, remove from the heat and set aside 8 to 10 minutes. Drain, cool in ice water and peel.
