If you're still struggling, peel the eggs under cold running water, which will help separate the shell from the egg. For a more eco-friendly solution than keeping your tap running, you can just peel the eggs in a water bath. The water will have the same effect of slipping under the shell and helping dislodge the egg.
If you're still having trouble, peeling eggs under a faucet with cold running water can encourage the shells to slide right off. Keep any eggs you won't be using right away unpeeled—they'll last longer that way! —and store in an airtight container in the fridge for up to 1 week.
Adding white vinegar or apple cider vinegar to your pot of water allegedly results in softer, easier-to-peel eggshells. That's because the acid in vinegar dissolves some of the calcium carbonate that makes up the egg's hard exterior.
Add baking soda to the boiling water.
According to PureWow, the alkaline baking soda helps increase the pH of the white albumen (that is, makes it less acidic), loosening the bond between the egg whites and the inner membrane of the shell.
Apparently super fresh eggs are difficult to peel because the pH of the white is more acidic which causes it to adhere to the shell membrane more tightly. Two solutions here – use older eggs or add a little bicarb soda to the cooking water to increase the pH.
Shocking your recently boiled eggs by submerging them into a bowl of ice water is key. The quick cooling of the hard-boiled eggs causes the egg whites to contract, freeing them from the membrane. If you let them cool for about 15 minutes, the peeling is much easier.
After 13 minutes at a simmer (not a boil—see full method below & read the tips to prevent cracking), immediately put the eggs in ice water to make them easy to peel. Shocking them in ice-cold water stops the cooking process.
Ideally, peel the eggs as soon as they're cool. Start at the broad end, and hold the egg under running water to loosen any bits of stubborn shell clinging to the sides. Another thing to keep in mind is the freshness of your eggs.
For maximum freshness, leave them in their shells until you are ready to eat or prepare. The shell will help to protect the egg from bacteria, and can help prevent them from absorbing odors from other foods in your refrigerator.
4 minutes for slightly set yolk and set white. 5 minutes for a medium cooked firmer yolk and white. 6 minutes for hard boiled with lightly soft yolk. 8 minutes for firmly hard boiled.
Give the eggs at least five minutes in the ice bath before you try to peel them—letting them cool may help make it easier to peel them, but it's also so you don't burn your hands.
Baking Soda
According to our friends at Delish, adding a teaspoon of baking soda to your boiling pot of water will help the shell peel off seamlessly. Why? The alkaline in the baking soda will help your egg whites loosen up from the shell, making it easier to peel.
Add salt and vinegar to the water.
The salt permeates the shell a little bit, and the vinegar helps to break down the shells, making them easier to peel.
When you plunge the eggs into a bowl of ice and water, the shock of the cold water stops the cooking process, preventing them from overcooking, explains The Spruce Eats. Otherwise, the residual heat in the eggs will continue to cook them, even after they have been removed from the source of heat.
Bring water to a boil over high heat, then reduce heat to moderately high and cook eggs at a gentle boil, uncovered, 10 minutes. Pour off hot water. If using eggs right away, shake pan gently so eggs bump into one another (to crack shells).
If you boil an egg for five or 10 minutes, it becomes firm and cooked. If you boil it for hours, it becomes rubbery and overcooked.
For one to four eggs, bring the water to a rolling boil, cover the pot, and turn the heat down to its lowest setting for 12-14 minutes. For five to eight eggs, cook for 15 to 18 minutes. For nine to one dozen eggs, cook for 20 minutes. After cooking, transfer the eggs to a bowl of ice water.
As soon as the water begins to boil, turn off the heat and cover the pot. Leave the eggs in the hot water for anywhere from 10-12 minutes, depending on how you like your eggs. The 10-minute eggs will have vibrant, creamy yolks, while the 12-minute yolks will be paler and opaque, with a chalkier texture.
