The recipe for hard boiled eggs is as follows: Fill a small saucepan about ⅔ full with cold water (for easy peeling, see below). Add the egg(s) and then turn on the stove to high heat. Once the water is rapidly bubbling, immediately turn off the heat and cover the saucepan with a lid.

- Soft Boiled Egg: For a soft boiled egg that has a very runny yolk similar to a poached egg, set aside, covered in the hot water for exactly 3 minutes before transferring to the ice bath. Cook for 4 minutes if you prefer a slightly firmer yolk and runny center (see this chart for more soft boiled egg cooking advice). Try soft boiled eggs on toast with asparagus or English muffin egg pizzas.
- Medium Boiled Egg: For ramen-ready eggs with a firm, slightly undercooked yolk, set aside, covered in the hot water for exactly 6 minutes before transferring to the ice bath.
- Hard Boiled Egg: To cook the perfect hard boiled egg, set aside, covered in the hot water for exactly 10 minutes before transferring to the ice bath. This is the ideal amount of time to cook a yolk that will be firm in texture, pale yellow in color, with no runniness. Use them in creative deviled eggs or clever mini quiches.
Easy to Peel Hard Boiled Eggs
Fresh eggs, week old eggs, baking soda, salt, peeling under cold tap water, gadgets galore—there are dozens of internet hacks for easy hard boiled egg peeling. I tried every trick I could find to make peeling hard boiled eggs easier— cooking the eggs in plain water, salted water, soaking the eggs in ice water, adding baking soda to the water, placing a towel in the pot with the eggs, and cooling them in the refrigerator. None of these worked well, especially when compared to the magic that happened when I added vinegar to my cooking water. Vinegar works because the acid breaks down the calcium carbonate in the eggshells, which make them softer and easier to peel. The eggshells peeled off in just a few large pieces, rather than dozens of tiny shards.
Try this technique at home by adding 1 tablespoon of distilled white vinegar to about 4 cups of water. Pour the liquid in a medium-sized pot, then cook your hard boiled eggs. After the hard boiled eggs finishing cooking, carefully transfer them to a bowl filled with ice water to chill for 5 minutes. The cold water will help to further soften the shell and make for even easier egg peeling.
