Preserving Eggs: The Ultimate Guide to the Safest and Best Methods

How to preserve eggs: The safest and best ways

Preserving eggs is a valuable skill to have, whether you have an abundance of eggs from your own chickens or want to take advantage of great deals at the grocery store. Knowing how to safely and effectively preserve eggs ensures that no eggs go to waste. In this article, we will explore the safest and best ways to preserve eggs, including freezing, lime water preservation, hard boiling, salt preservation, and water glassing.

Storing Fresh Eggs

Before looking at the different methods of preserving eggs, it is important to understand how long you can store fresh eggs. Knowing the shelf life of fresh eggs will help you determine if you need to preserve them.
For store-bought eggs, it is best to store them in the main part of the refrigerator rather than on the refrigerator door. This helps to maintain a consistent temperature. In addition, keeping eggs in the carton they were sold in helps prevent them from picking up odors and flavors from other foods. The “best by” date is clearly marked on the carton to help ensure freshness.
If you have your own chickens and freshly laid eggs, you can store them on your kitchen counter. The eggs have a protective membrane coating that keeps them safe. However, it is important to use these eggs within 3-4 days and to remove any debris from the shell before consumption.

Preserving eggs by freezing

Freezing eggs is one of the easiest and most accessible methods of preservation. When freezing eggs, it is recommended to lightly scramble them before freezing, as this gives better results than freezing them whole.
One method of freezing eggs is to use a standard muffin tray. Crack an egg into each well of the tray or pour enough lightly scrambled eggs to fill the tray about ¾ full. Lightly spray the muffin tray with nonstick oil before adding the eggs. Place the tray in the freezer until the eggs are frozen solid. Once frozen, remove the egg cups from the tray and place in a plastic freezer bag. Squeeze out as much air as possible and seal the bag tightly, doubling the bag if necessary. Don’t forget to label the bag with the freezing date.
Another option is to freeze eggs in an ice cube tray. Look for a tray that has molds that can hold either ½ or 1 whole egg. Follow the same steps as the muffin tray method, but adjust the measurements accordingly. When you are ready to use the frozen eggs, simply open the freezer container and remove as many egg cubes as you need. Use frozen eggs within 4 months for optimal quality.

Hard boil egg preservation

If you need to preserve eggs for a short period of time, such as a few days or a week, hard boiling is a simple and effective method. While hard-boiled eggs will only keep for about 7 days, this method extends their shelf life without the need for extensive preservation techniques.
To hard-boil eggs, place an appropriate number of eggs in a saucepan and cover with water. Boil the eggs for the appropriate amount of time to ensure that both the white and yolk are fully cooked. Once boiled, transfer the eggs to the refrigerator and store for up to 7 days. Hard-boiled eggs can be enjoyed as a snack, used in sandwiches or salads, or prepared as deviled eggs for holiday gatherings.

Preserving eggs in lime water

Lime water egg preservation is an excellent long-term preservation method that allows eggs to be stored for up to a year or more. This technique uses pickling lime, which helps seal and preserve the eggs without introducing any additional flavors or tastes.
To preserve eggs in lime water, make a solution by mixing approximately 1 ounce of lime powder with 1 quart of water. Shake the container to ensure proper mixing; the solution should appear milky white. Select fresh, clean eggs without cracks or blemishes. Place the eggs in a large, sterilized jar and pour the lime-water solution over them, making sure all the eggs are completely submerged and the jar is filled. Seal the jar tightly, label it with the expiration date, and store it in a cool, dry place such as a pantry or basement.
When you need to use the preserved eggs, remove the desired amount from the jar with clean tongs or after washing your hands. Rinse the eggs under running water to remove any traces of lime water. The preserved eggs can be cracked and used in recipes while retaining their flavor and texture. The egg whites can even be whipped into stiff peaks.

Preserving eggs in salt

Preserving eggs in salt and fat is another method that prolongs their freshness for a considerable period of time. However, this technique requires plenty of storage space.
To preserve eggs in salt, begin by pouring a thick layer of rock salt into a foam cooler or similar container. Make small indentations in the salt bed and carefully place the eggs into the indentations with the shell side down. Make sure the eggs do not touch each other and are completely submerged in the salt. Cover the eggs completely with another layer of rock salt, making sure there are no exposed areas. Close the cooler tightly and store in a cool, dry place.
When you are ready to use the preserved eggs, simply remove them from the salt bed, brush off any excess salt, and rinse under running water to remove any remaining salt. The preserved eggs can then be used in a variety of recipes or enjoyed as a snack.

Preserving eggs with water glass

Water glassing, also known as sodium silicate preservation, is an ancient method of preserving eggs without refrigeration. The technique involves coating eggs with a mineral solution, creating a protective barrier that inhibits bacterial growth and prolongs shelf life.
To preserve eggs with water glass, begin by cleaning and sanitizing a large glass or ceramic container with a tight-fitting lid. Prepare a solution by mixing water glass (sodium silicate) with water according to the manufacturer’s instructions. Carefully place the eggs in the solution, making sure they are completely submerged. Close the container tightly and store in a cool, dark place such as a basement or root cellar.
When it is time to use the preserved eggs, remove them from the solution, rinse under running water, and use as desired. Water-soaked eggs can be used in recipes that call for raw or cooked eggs, such as baking or scrambling.


Preserving eggs is a valuable skill that allows you to make the most of your egg supply and reduce waste. By using a variety of methods, such as freezing, brining, hard boiling, salting, and water glassing, you can extend the shelf life of eggs and enjoy them long after their sell-by date. Each method offers its own benefits, so choose the one that suits your preferences and available resources. By mastering the art of egg preservation, you can ensure a steady supply of eggs for your culinary needs throughout the year.
