A Complete Hard-Boiled Egg Guide: How Long to Cook Eggs to Hard Boil

Last Updated on 7th June 2023 by

For many, a morning meal is not complete without eggs. It’s safe to say that among all food products, eggs are staple morning dishes that can be cooked in various ways and incorporated into various dishes to enhance and improve their composition and flavor. Heck, you can even eat eggs during lunch or dinner if you want to.

They’re excellent, nutritious, and fresh protein sources available all year round, anywhere and everywhere. I can guarantee you a better day if you start with one egg a day.

Before we discuss how to make a hard-boiled egg, what’s in an egg?

Egg Nutrition Facts

Let me cover how nutritious eggs are and why they can be considered superfoods.

When it comes to protein, only milk beats eggs. A single egg contains only 75 calories but an impressive 7 grams of high-quality protein, 5 grams of fat, 1.6 grams of saturated fat, and vitamins, iron, and minerals. Did you know that two eggs supply your body with 82% of your daily Vitamin D requirements, 50% folate requirements, 25% riboflavin, and 40% selenium requirements?

Does that seem like a lot? Because it is! Eggs are very healthy for the body and if you do not suffer any adverse reactions or allergies, consider including them in your daily diet.

How to Cook a Hard-Boiled Egg

Cooking hard-boiled eggs is a no-brainer! Leave the raw egg onto a pot of water, let it boil, sit at your desired time, and then voila! You have yourself a hard-boiled egg.

The problem, however, lies in personal preference. Some people like their hard-boiled eggs, very mushy, some quite like it just a bit mushy, and others prefer it very well-cooked. I personally prefer it well in between mushy and well-cooked.

Whatever your preference is, it all boils (pun intended!) down to how long you let a raw egg boil for and the strength of your flames. Just as the perfect hard-boiled egg is easy to make, so are less than perfect ones.

First off, put your raw eggs into a pot and cover with cold water up to 1 inch higher than the egg. There’s been a debate over using hot or cold water to boil the eggs, and either way will cook the egg just fine. Really, you don’t need to stress about it.

However, cold water will separate the membrane from the shell (that rubbery texture when you peel) and make it easier for you to peel eggs properly. Bring the water to high heat and let boil.

How Long to Boil an Egg for Hard-Boiled Eggs

For regular to large shaped eggs, you would want to cook up to 4 minutes for mushy and runny soft boiled eggs, 6 to 8 minutes for medium, a bit mushy but also hard-boiled eggs, and 10 to 12 minutes for the firm, hard-boiled eggs.

Turn off the heat after your desired time, turn off the heat and carefully remove the eggs from the pot, and give them a nice ice bath. This will halt the cooking process inside the egg so your egg is as cooked as you estimated by the time you remove them as the internal heat will keep on cooking the egg despite being out of the boiling water.

This will also prevent a green ring from forming around the yolk, which means you have terribly overcooked your eggs.

Another tip is to use eggs that have stayed in the fridge the longest. They are easier to peel.

How Long Is a Hard-Boiled Egg Good For?

Hard-boiled eggs that were immediately cooled and stored can be kept in the refrigerator with the shell on and sealed in a container for four days up to one week.

However, peeled ones should be consumed within 48 hours as the white egg surface can attract microorganism growth because of its moisture.

You can place the hard-boiled eggs in a sealed container or bag that you can put a date on to consume first those that were cooked earlier.

Also, remember to separate raw eggs from boiled eggs because they look similar, and cross-contamination can occur from raw eggs to cooked ones.
