In this post, I will share with you a handful of tips and tricks to achieve the perfect boiled eggs. From selecting the eggs to the appropriate cooking times and temperature, I have got you covered. Whether you are a boiled egg enthusiast or simply looking to improve your cooking skills, this guide will help you take your egg-boiling game to the next level. Once you have perfected your technique, you might want to try your hand at poached eggs as well.
Do Not Boil Your Boiled Eggs
Perfectly boiled eggs are a delicate balance of temperature, timing, and technique. The traditional method of boiling eggs, where the eggs are placed in a pot of rapidly boiling water, can lead to tough whites, overcooked yolks, and cracked shells. However, by simmering eggs instead of boiling them, you can achieve the perfect consistency every time.
Simmering involves cooking the eggs in water that is just below the boiling point. This gentle process allows for more controlled and consistent cooking, leading to tender whites, yolks cooked to your desired consistency, and unbroken shells. If you are not familiar with the difference between simmering and boiling, my cooking terms glossary covers these and many other essential techniques.
To simmer eggs, fill a pot with enough water to cover the eggs by about an inch, and bring the water to a simmer (just before it reaches a full boil). Gently place the eggs in the pot and cook them for the desired time, depending on whether you want soft, medium, or hard-boiled eggs. This method is particularly useful for hard-boiled eggs, as it allows for a consistent final product while cooking for a longer period of time.
Fresh Eggs Are Harder to Peel
Peeling boiled eggs can be a frustrating task, especially when the shell stubbornly sticks to the white and leaves chunks of the egg behind. Many people assume that the problem is with their cooking technique, but it is often the result of using fresh eggs. As counterintuitive as it may sound, using eggs that are slightly older can make peeling them much easier.
The reason behind this is that as eggs age, the pH levels of the whites change, and the protein bonds within them weaken. This makes it easier for the shells to separate from the whites when the eggs are boiled. However, you may not always have the option to wait for your eggs to age before boiling them. In that case, there are a few tricks you can use to make peeling easier:
- Room temperature: Place your eggs on the counter at room temperature for an hour or two before boiling them. This helps loosen the bond between the egg and the shell.
- Baking soda: Add 1 teaspoon of baking soda for every litre of water while boiling. The baking soda slightly softens the shell, making it easier to peel without affecting the taste or quality of the eggs.
Different Methods, Same Results
Cooking boiled eggs can be achieved through various techniques, each with its own advantages and disadvantages. Two popular stovetop methods are:
- Cold start, heat off: Start the eggs in cold water, bring it to a boil, then turn off the heat and let the eggs sit for a set amount of time.
- Cold start, keep boiling: Start the eggs in cold water, bring it to a boil, and then boil the eggs for a set amount of time.
However, my preferred technique is starting with boiling water, adding the eggs, bringing it back to a boil, and then reducing the heat to a simmer and cooking the eggs for a set amount of time. This method offers the most accurate cook on the eggs and eliminates many of the variables that can lead to overcooking. Before adding the eggs to boiling water, bring them to room temperature or run them under slightly warm water to prevent the shells from cracking.
Instant Pot Method
Cooking eggs in an Instant Pot involves steaming eggs under high pressure, which speeds up the cooking process. Place eggs on the trivet in the Instant Pot with 1 cup of water. Cook on high pressure for 5 minutes for soft-boiled eggs, 8 minutes for medium-boiled eggs, and 12 minutes for hard-boiled eggs. Release the pressure naturally for 5 minutes before quick release.
Sous Vide Method
Sous vide cooking is a method where the eggs are immersed in water at a precisely controlled temperature for a specific amount of time:
- Soft-boiled: 63C (145F) for 45 minutes to 1 hour
- Medium-boiled: 64C (147F) for 1-2 hours
- Hard-boiled: 71C (149F) for 2-4 hours
Sous vide cooking allows for a high level of precision and consistent results. However, it does require specialized equipment such as a sous vide immersion circulator. While each method has its own set of pros and cons, all of them can produce perfectly cooked eggs. The important thing is to choose the method that best suits your needs and preferences.
Rinse the Eggs to Remove the Shell
Once you have cooked your eggs to perfection, the next step is to remove the shells. While this may seem simple, the shells can stubbornly stick to the whites, making it difficult to peel cleanly. However, there is a simple trick that can make shell removal much easier: rinsing the eggs in cold water.
When you drain the water from the pot after cooking, gently crack the shells of the eggs all over with the back of a spoon or by tapping them on the counter. Then, submerge the eggs in cold water for a few seconds. This causes the membrane under the shell to shrink and pull away from the egg, making it much easier to peel the shell off. Do not worry, this will not cool the eggs too much.
You can also use this method when peeling hard-boiled eggs that have been sitting in the refrigerator. Simply place the eggs in a bowl of cold water, and let them sit for a few minutes before peeling.
Time Is of the Essence
The final key to perfect boiled eggs is time. It is the only other variable you need to control to achieve the desired level of doneness. The cooking time will vary depending on the method you choose.
For the traditional method of simmering in boiling water, it is essential to consider the desired level of doneness. Here are the times for each method:
Soft Yolk, Set Whites
- Traditional (simmering): 4 ½ - 5 minutes
- Instant Pot: 5 minutes high pressure, 5 minutes natural release
- Sous vide: 63C (145F) for 45 minutes to 1 hour
Medium Yolks
- Traditional (simmering): 6 ½ - 7 minutes
- Instant Pot: 8 minutes high pressure, 5 minutes natural release
- Sous vide: 64C (147F) for 1-2 hours
Hard Yolks
- Traditional (simmering): 9 ½ - 10 minutes
- Instant Pot: 12 minutes high pressure, 5 minutes natural release
- Sous vide: 65C (149F) for 2-4 hours
Cooking eggs for too short or too long can result in overcooked or undercooked eggs. The ideal time will vary based on personal preference and the method used. Use a timer -- it makes all the difference.
Bonus Tip: Stop the Cooking
Once the eggs are cooked, they will still have quite a lot of heat contained in them. If this is not dealt with, the eggs can overcook. This is especially true if the eggs are not going to be eaten right away. To combat this you can cook the eggs slightly less than you normally would, and you can shock the eggs in cold water. Shocking the eggs by rinsing them or submerging them in very cold water for 1-2 minutes will stop the cooking process. This should not cool the eggs down so much that they are no longer enjoyable.
Final Thoughts
I have cooked thousands of eggs over the years and the simmering method remains my favourite for its consistency and simplicity. Once you nail the timing, perfect boiled eggs become second nature, and you can use them in everything from potato salad to Devilled Egg Sandwiches.
Frequently Asked Questions
Despite the name, eggs should be simmered rather than boiled. The high heat and vigorous movement of a rolling boil can toughen the whites, overcook the yolks (causing a green ring and sulphur taste), and crack the shells. Simmering in water just below the boiling point gives you tender whites and perfectly cooked yolks every time.
Using the traditional simmering method, a soft-boiled egg with a runny yolk and set whites takes 4 ½ to 5 minutes. Start timing once the water returns to a simmer after adding the eggs. For an Instant Pot, cook on high pressure for 5 minutes with a 5-minute natural release.
As eggs age, the pH levels of the whites change and the protein bonds weaken. This makes it easier for the shell to separate from the white after cooking. With very fresh eggs, the membrane clings tightly to the white, causing chunks to tear away when you peel. Using slightly older eggs, bringing eggs to room temperature before cooking, or adding baking soda to the water can all help.
The green ring around the yolk of a hard-boiled egg is caused by overcooking. It happens when iron in the yolk reacts with hydrogen sulphide in the white at high temperatures. To prevent it, simmer instead of boil, time your eggs carefully, and shock them in cold water immediately after cooking to stop the residual heat from continuing to cook the yolk.
The best method depends on your needs. For the most control and consistency, the traditional simmering method (starting with boiling water, adding eggs, then reducing to a simmer) is preferred. For a hands-off approach, the Instant Pot is excellent. Sous vide offers the highest precision but requires specialized equipment and significantly longer cooking times.
