21 Ways to Preserve Eggs That Are Pure Genius

If we are fortunate enough to have gotten through a bad time and have a secure place to live, then thoughts inevitably turn toward producing and preserving enough food to feed us and our families.

Having chickens that can provide us with eggs is one of the most ideal ways to have a solid, healthy source of food literally in our own backyard. Plus, eggs are a highly nutritious source of protein, vitamins, and minerals that will keep our tummies full and our bodies fueled.

In a post-collapse world, chances are you will not have refrigeration, and even if you do, your chickens will have an egg-laying schedule that does not jive with your eating schedule. At times, chickens produce far more eggs than you can eat, and at other times, they don’t produce anything.

By knowing a bunch of egg preservation methods, you can even out the supply of these little white (or brown) gems and be eating eggs throughout the year.

Things to Know Beforehand

First and foremost, you can’t take just any eggs and preserve them. Eggs off the grocery store shelf won’t work, at least when it comes to North American grocery stores.

In much of the world, grocers keep their eggs unwashed and unrefrigerated. These eggs are only washed when it is time to use them. In North America, the fear of lawsuits ensures our store-bought eggs are presented clean and pretty.

It is critical that you use unwashed, farm-fresh eggs that are clear of cracks. Why unwashed you ask? Because eggs straight from the chicken and unwashed actually come with a natural sealing agent called bloom. This bloom protects the egg from the environment around it, sealing it off from bacteria, oxygen, and any other nasties floating around in the air.

Now, there are many ways to keep eggs, both with or without refrigeration and each preservation method has its own advantages and disadvantages. Some of these methods are better than others. Some are easier than others. Let’s take a look at the best methods of preserving eggs.

#1. Just Let Them Sit

Yup, as long as you have fresh, unwashed eggs, you can simply let them sit, provided the temperature does not get above 55 degrees Fahrenheit (12 degrees Celsius). A cold room would work well.

Eggs will keep for up to three months like this, provided the humidity level is around 75%. If you are keeping the eggs on your counter, they will last for two weeks. Remember to keep the eggs in the carton because it helps reduce the amount of condensation on the shells.

#2. Sealed Container in Fridge

If you do have refrigeration, then the very best way to store eggs for the long term is to put them in a sealed container or their carton in the fridge. They should be stored between 35 and 40 degrees Fahrenheit (2 and 5 degrees Celsius) and will keep that way for at least seven months.

After this amount of time, the whites might get a little runny, but otherwise, the texture is good and they taste great.

Salt is a very good preservative, so no wonder it works with eggs too.

#3. Storage in Salt, or Wet Clay

The ancient Chinese people used to store their eggs in salt and lime, wet clay, cooked rice, or salt and wood ashes mixed in an infusion of tea. These eggs would be stored for years this way, and although they looked bad (yolks that were greenish-gray and albumen that looked brown and jelly-like) they could be safely eaten.

#4. Cured Egg Yolks

This is a great way to preserve the yolks of your eggs. You will want to put down half an inch of salt in a container of some sort.

Make depressions in the salt that will hold the yolks. Then you will separate the egg yolks from the whites, making sure that the yolk does not break.

Set the whites aside to use later and place the yolk on the salt. You can place more than one yolk side by side if the container is big enough, but do not let them touch more than slightly so the salt can surround them.

Pour more salt over the yolks and cover the container. Leave them in the fridge for one week, then remove them from the salt. The yolks will be hard by this time:

Wrap them in cheesecloth and hang them in the fridge for one to two weeks. You can then leave them in the cheesecloth and store them in a container in the fridge. They will keep for at least a year this way.

#5. Freezing

You can put the ice cube trays directly into the freezer, or you can take the frozen eggs out and move them to a Ziploc bag.

Yes, you can freeze eggs! Again, this is if you have electricity and the ability to do this. You will need to remove them from their shells to freeze them. You can mix them together or freeze them separately. Small portions work well for this method of preparation and using an ice cube tray is ideal.

One egg will fill two compartments in an ice cube tray. Another great option is a popsicle mold. When you want to use the eggs, take them from the freezer, and let them thaw in the fridge, and then you can scramble them, make French toast, or bake with them.

#6. Coating/Immersing in Oil

Coating fresh eggs in food-grade mineral oil is a great way to preserve eggs. You will want to use ¼ cup oil for 4-6 dozen eggs:

coating an egg with oil
Mineral oil shouldn’t be handled with your bare hands… use some gloves instead!
  1. Warm the oil and lay your eggs out on the counter.
  2. Wear food-handling gloves and get some oil on your hands.
  3. Then pick up an egg and rub the oil all over it. It can go on thick, but the most important thing is to ensure the entire surface of the shell is coated.
  4. Repeat this with all the eggs, replacing them in the cartons with the smaller, pointy side down.

You can store these for a few weeks at room temperature and longer at slightly cooler temperatures, about 68 degrees Fahrenheit (20 degrees Celsius). You should turn the carton over once a month so that the yolk will remain intact.

An alternative to this is to immerse the eggs in food-grade mineral oil, olive oil, or another type of oil in a large sealable container, such as a food-grade 5-gallon bucket. This will buffer the eggs from the air very well. You can also coat the eggs in lard or shortening.

Finally, when coated in oil and stored this way, the eggs are no longer usable as a leavening agent when making cakes.

Finally, you can thermos-stabilize the eggs prior to coating them in oil. This is done by immersing the eggs in boiling water for a short time in order to cause a thin layer of albumen to coagulate directly beneath the shell.

However, when the egg is used, you will have this consistency that you might not want, depending on your intended use for the eggs.

#7. Water-Glass Solution

Water-glass is a solution of sodium silicate that will fill the pores of the eggshell to keep out air and contaminants. It is a method of egg preservation that has been used for decades and was particularly popular during World War II.

Water-glass comes in powder form and you mix one part water glass to nine parts water (or as directed on packaging). Be sure to boil the water and cool it first to ensure it is free of bacteria and other contaminants.

Preserving Protein for Winter: Waterglass

Once you have the water-glass solution mixed, ideally in an earthenware crock, place the eggs in the solution, ensuring there is a minimum of 2 inches of water-glass above the eggs.

You will get about 16 dozen eggs preserved for every quart of water-glass solution and the eggs will keep for several months.

There are some things to remember about water-glass preservation. First, the best eggs to use are those that are at most three days past laying. Shells must be clean (wiped with a damp cloth; not washed) and there must be no cracks in any of the eggs.

One egg with even the tiniest crack will go bad and one bad egg will cause all the other eggs in the solution to spoil. Also be sure to sterilize the crock before using and go by a first-in-first-out procedure when using the eggs.

#8. Liquid Isinglass

Isinglass is a form of gelatin obtained from fish, particularly sturgeon, and it is resistant to bacteria. Note that liquid paraffin can also be used. As with water-glass, the eggs should be wiped clean and free of cracks:

  1. Mix the Isinglass with water according to the package directions.
  2. Heat the mixture and then let it cool.
  3. Once cooled it will be a white jelly-like liquid.
  4. Place eggs pointed end down in a crock and pour the cool Isinglass over the eggs, completely covering them.

You can then cover the crock to keep dirt out and remove eggs only as you need them.

#9. Egg Preservation French-Style

The French style of preserving eggs is a variation of the oil preservation:

  1. You will melt 2 ounces of beeswax into 4 ounces of olive oil.
  2. Dip your eggs into the wax-oil mixture and lay them to dry.
  3. Then place them pointy side down in an air-tight container that contains course sea salt.
  4. The eggs must be completely covered by the salt and they cannot be touching each other. They will keep for up to two years in this manner.

Pickling is a fantastic way to preserve eggs and it’s easy to do even if you’re a newbie.

#10. Pickling

You might think of pickling as something you do with plant-based foods, but you can also pickle eggs. Pickling eggs is a great and tasty way to preserve them. Be sure to have your jar(s) sterilized ahead of time.

Choose fresh eggs and hard boil them using your preferred method. Once boiled, transfer the eggs to an ice bath and when they are cooled, peel the eggs and place them in your sterilized jar.

Next, you need to make your brine. You will need:

  • 6 cups water
  • ½ cup apple cider vinegar
  • ¼ cup sugar
  • Any seasonings you choose, such as salt and peppercorns or curry seasonings
  • Beet juice (optional if you want pink eggs)

Bring the brine to a boil and let it simmer for ten minutes, then strain it and pour it into the jar with the eggs. Be sure to completely cover the eggs with the brine. Put on the lid tightly and refrigerate.

You will need to wait between one and four weeks for the eggs to absorb the seasoning, depending on the size of the eggs. They will keep up to four months.

#11. Dehydration

Making dehydrated eggs is quite easy. You can either crack them or mix them together or you can separate the yolks from the whites and dehydrate these separately.

Spread them in thin layers on the dehydrator trays (be careful, they will run easily!) and dehydrate them at 135 degrees for 6-8 hours. Stirring the eggs about halfway through the dehydration process will help get rid of any skin forming on top of the eggs.

Once done you can crumble or powder the eggs and store them in jars. If powdered finely enough, you might be able to fit a dozen eggs into ½ pint jar!

The best thing is, once the eggs are reconstituted, they can be cooked up or used in baking the same as fresh eggs, yet it takes so much less space to store them than it takes for whole eggs.

#12. Waxed (Using Beeswax or Paraffin)

It is possible to use beeswax or common paraffin wax to preserve your eggs. This works, as you would expect, by sealing the pores of the eggs, and the thick, solid nature of cooled wax provides a better seal than other substances.

However, the process is pretty laborious and requires dunking them multiple times in hot wax using special tongs. Ideally, you will seal the eggs in an airtight container after coating. Eggs waxed in this way will keep for around 6 months.

#13. As Egg Pasta

One clever way to store your eggs is as pasta. You can use any egg pasta recipe you prefer and a homemade pasta maker for the purpose, but you don’t have to have one. A rolling pin works just as well.

Once the pasta is finished be sure to dry it carefully to prevent molding and then you can store it like any other dry good using various techniques to extend the shelf life. You can easily get 9 months to a year from your eggs using this method.

#14. Coated with Butter

One clever trick for preserving eggs easily uses nothing more than common butter. This works as you would expect by sealing up the pores of the egg and preventing dehydration.

coating an egg with butter
Coating an egg with butter is, as you can see, pretty trivial.

Keep in mind that the butter will eventually go rancid itself, ruining the egg, but if you keep them in a cool spot after buttering them they can keep for several months.

This technique has been around for quite a while, but note that it works best when the eggs are as fresh as possible. Just wipe them off and then wipe them down with butter before storing.

#15. Coated with Lard

Similar to coating your eggs with butter, lard can be used to keep them sealed and hydrated.

coating an egg with lard using a sponge
Coating eggs with lard is straightforward and doesn’t require any special equipment.

This method is effective at preventing spoilage but it does have the disadvantage of the lard going rancid in time, like butter, and also the eggs slowly absorbing the lard over time; that’s probably not good for you and has a decent probability of affecting the taste of the eggs.

If you use lard to preserve your eggs they can keep a few months on the counter or as long as a year in the refrigerator.

#16. In Lime Water

In this method, lime water has nothing to do with citrus fruit. We are referring to lime, the mineral, the same one used for pickling lime.

Note this is more than merely mixing the lime with water because the ratios must be precise and then the heavier minerals should be allowed to settle while you draw the saturated lime water off the top.

It sounds a bit strange and involved, and it is, but it is not that difficult and it has the advantage of preserving the quality of your eggs excellently. It is also easy to do at home with very cheap supplies. Limes preserved in this way will keep for months at the least.

#17. Egg Liqueur

As bizarre as it sounds to most Americans, eggs can actually be preserved in liquor, and not just in the form of eggnog! There are all kinds of recipes hailing from various cultures around the world, and each of them has strong alcohol as the basis for preserving the eggs kept in them.

Even in the case of cocktails and mixed drinks like eggnog, these can often be kept refrigerated for several months so long as they have plenty of alcohol in them. 

#18. Freeze-Dried

Freeze-drying is not the same as simple dehydration and not the same as freezing. The freeze-drying process works my driving pretty much all of the moisture out of food, including eggs, creating a product with a hard, powdery texture that can be rehydrated later.

The major advantage of freeze-drying is that produces dry goods capable of lasting decades in cool, dry storage. Home freeze-drying tech is very expensive, so you might be better off purchasing freeze-dried eggs commercially if you want to add some to your long-term storage pantry.

#19. In the Root Cellar

Root cellar storage has long been the standard for easy extended keeping of eggs, and root cellars today are making a comeback. If you keep fresh, unwashed eggs in a cool Root cellar with high humidity they will easily last for 2 months, perhaps longer.

Remember, you don’t want to use washed eggs for this purpose because removing the bloom from the eggshell accelerates dehydration and spoilage. The fresher the better, otherwise use root cellar storage in conjunction with another method of preservation on this list.

#20. As Canned Lemon Curd

Making lemon curd is a great way to consume a lot of surplus eggs, and so long as you pay attention to canning it properly the resulting lemon curd can be canned safely for an extended period of time, at least a year. 

Ultimately you can freeze the lemon curd without canning it to keep it even longer than a year with very little degradation and quality. 

#21. In Any Other Preserved Dishes

Think outside the box when it comes to preserving your eggs for the Long haul by using them in other dishes, or ingredients for other dishes, prior to preserving them. This could be something like lemon curd as detailed above, or even something like a brownie batter. Various other doughs are always a good option, too.

Storage life varies depending on what you make, and how you preserve it, but this can give you far greater flexibility than just trying to preserve the eggs themselves as they are.

Final Tips

Regardless of how you have chosen to preserve your eggs, be sure that when it comes time to use them you break them over a separate dish, rather than over the food to which you are adding them or the pan in which you are cooking them.

There are two reasons for this, the first of which is that these are unwashed eggs that might still have chicken doo-doo on them or other nasty stuff from the hen house.

For this reason, you should also separate eggs with your hand, rather than the shell…

The second reason is that you might end up with the odd spoiled egg and you should make sure they are good before you add them to the pan or the food. It is always wise to test the eggs by placing them in a dish of water. If any of them float, then they are spoiled and you don’t want them.

Preserving eggs to keep in your food stores is smart because it will ensure your family has a good source of protein when food is scarce.

Having enough eggs in your food stores to get you by until you can establish a new food source will give you considerable peace of mind, particularly when the going gets tough.

At the very least, preserving your eggs, even in good times, will ensure you don’t waste eggs when your chickens go on a laying binge.

  1. Great article, we use the food grade mineral oil method on our store bought eggs to get more more shelf like and go augment our home layed chicken eggs.

  2. I have used slaked lime in water to store eggs for up to one year. Cooler temps extend the storage time.

  3. Thank you for the great list of preservation techniques! I am curious about where you got the instructions for room temperature egg storage? The information I got a few years ago was from Mother Earth News. They said they did the original research a couple of decades ago, but the article got so much attention that they kept it updated. Their instructions were to check fresh eggs for cracks or signs of having been wet and set those aside for immediate use or refrigeration, to dry wipe off the eggs and store them in a quiet spot at above freezing and below 90F. The stored eggs should be used within a prudent 90 days, but could be stored for up to 120 days. I have seen the article as a link in numerous places. I often give my eggs to friends, so I set aside the ones with feces or mystery markings to wash and boil for my use. The rest are packed in pasteboard cartons and kept in a cool, well ventilated shelf protected from sunlight. No problems and no complaints from my friends.
