How to Make Hard Boiled Eggs

As we learn how to boil eggs, we must not forget there are different kinds of boiled eggs – one of which is hard-boiled eggs. Firstly, what is a hard-boiled egg? A hard-boiled egg is an egg that is cooked so that the white part and the yolk part both solidify. How then can you boil an egg to ensure that it hard boils? The following steps are a perfect guide to successfully hard boil eggs.

Step 1:

Fill a saucepan to about a quarter with water. Place the number of eggs you wish to cook to the single layer at the bottom of the saucepan. Make sure the eggs are covered by an inch of water. You must make sure you add more water to the pan so that the ratio of water is proportionate to the number of eggs you add to the saucepan. Also, ensure that as the number of eggs increases, the higher the level of water that should cover the eggs.

Step 2:

Apply a considerable amount of heat to the saucepan and content. Ensure it is brought to a full rolling boil. At this point, you must note that it is important to take extra care to ensure the white part of the eggs do not come out. Adding a small amount of vinegar to the water will prevent the white part from coming out in case the egg cracks. To avoid cracking, add half a spoon of salt. This will also help the egg peel easily.

Step 3:

After boiling for some time, turn off your cooker and allow the saucepan to rest on the cooker for 10 to 12 minutes. If you are using a cooker like a stove that can retain heat, you might want to lower it and allow it to simmer for a minute before turning it off.

In some instances, you can boil the egg for up to 15 minutes. Take note that 15 minutes of eggs result in extremely hard-boiled eggs. Furthermore, 10-minute eggs, and 8-minute eggs are also still considered hard-boiled. The time factor is dependent on how hard-boiled you want your eggs. Be sure not to overcook your eggs, either.

The Final Step:

Strain the hot water from the pan and immediately run cold water over it to cool them and prevent them from cooking further.


How Long Do Hard Boiled Eggs Last?

Learning how to hard boil eggs is one thing. The next matter is knowing how to store hard-boiled eggs. One of the ways is to preserve them in a refrigerator for use later. Hard-boiled eggs can be stored in the refrigerator from anywhere between four days to one week, either peeled or unpeeled.

How to Make Soft Boiled Eggs

In contrast to hard boiled eggs, another method to boiling eggs is by going the soft boiled route. Soft boiled eggs are a unique variety of boiled eggs that are characterized by a thick white part and a silky yellow part. It means the yolk part of the eggs does not solidify, as is the case in hard-boiled eggs. Some people have a preference for soft boiled eggs over hard boiled eggs, which is why knowing how to boil eggs this way can be just as important.


  • The first step is to add water to your saucepan. Add your eggs on the saucepan layer. Ensure you add a small quantity of water.
  • Then, place the water on your cooking gas and heat to the boiling point.
  • Once the water comes to a boil, quickly place the eggs into the boiling water using tongs to avoid burning your finger in the hot water.
  • After adding the eggs, place the lid of the saucepan back and allow the egg to boil for exactly six minutes. The lid helps the saucepan hold more heat, therefore making the eggs boil evenly and cook quickly.
  • After six minutes, transfer the eggs to an ice bath. This will enable the eggs to cool faster.
  • After cooling the eggs, make sure you avoid exposing them to high temperatures. Any such attempt will continue to cook the egg and cause the soft yolk to solidify. This is an important point to note on how to boil eggs.
  • To peel the eggs, gently tap the hard external part of the egg to avoid spilling the liquid egg yolk. Begin peeling from the fat end and rinse immediately to remove any remaining shell.

How Long Can a Soft Boiled Egg be Stored?

Soft boiled eggs can typically last for about two to three days if kept refrigerated with its shell.
