tip Friday Learning how Long Eggs Will Keep
How Long Will Raw and Hard Boiled Eggs Keep? How do you store them?
The answer to this question may surprise you!
While uncooked eggs typically last four to five weeks when properly refrigerated, hard-boiled eggs will only last about a week.
This is because egg shells, which are highly porous, are sprayed before sale with a thin coating of mineral oil that seals the egg.
Boiling the egg washes this coating away, however, leaving the shell susceptible to bacteria.
Store Bought Eggs
Refrigerator Storage: Refrigerate eggs at 40°F or less. Store them in their original carton on an inside shelf and away from pungent foods. The temperature on an inside shelf remains more constant than one on the door, which is opened and closed frequently. The carton keeps the eggs from picking up odors or flavors from other foods and helps prevent moisture loss. The eggs can last 4-5 days past the date on the carton. This date is the packed date and not the expiration date.
Raw eggs that have been removed from their shells should be refrigerated in a tightly covered container. Refrigerated whole egg yolks should be covered with water to prevent them from drying out. Drain these eggs before using.
Freezer Storage: If you have more eggs than you can use within a few weeks you can freeze them out of their shells. Freeze only clean, fresh eggs. Place them in freezer containers, seal tightly and label with the number of eggs, whites or yolks and the date. Defrost frozen eggs overnight in the refrigerator.
Egg yolks thicken when frozen. To slow formation, beat in either 1/8 teaspoon salt or 1-1/2 teaspoons sugar or corn syrup per ¼ cup yolks (4 Large) before freezing. These can last up to 1 year. Do not freeze hard boiled eggs. They become tough and watery.
Hard Boiled Eggs
Hard boiled eggs, peeled or unpeeled, are still safe to eat up to one week after they were cooked. Keep them stored in the refrigerator, and you should consider writing the boiling date on each egg to know if they’re still good!
Proper storage of eggs can affect both quality and safety.
- Use hard-cooked eggs (in the shell or peeled) within 1 week after cooking.
- Use frozen eggs within 1 year. Eggs should not be frozen in their shells. To freeze whole eggs, beat yolks and whites together. Egg whites can also be frozen by themselves.
- Refrigerate leftover cooked egg dishes and use within 3 to 4 days. When refrigerating a large amount of a hot egg containing leftover, divide it into several shallow containers so it will cool quickly.
Farm Fresh Eggs
To no surprise Farm Fresh Eggs have the longest expiration date. These are eggs plucked right from the chicken.
Many small farmers and backyard chicken keepers advise that unwashed eggs can be kept at room temperature for up to 30 days. Once washed they need to be refrigerated at between 35 – 40 degrees F and are typically good for 6 – 8 weeks
There is a natural waxy coating on an egg that makes the shell impermeable. Nothing can get through that coating, not water, air, feces, nothing. So don’t wash farm fresh eggs until they are ready to be used,
