How to correctly store boiled eggs
During boiling, the protective layer that coats the shell is removed, making the eggs more susceptible to air and harmful microorganisms.
Therefore, refrigeration is imperative to prevent hard-boiled eggs from contaminating or spoiling.
Storing them in your fridge helps to slow bacterial growth, as potentially dangerous bacteria grow slower in temperatures below 40°F (4°C).
Avoid keeping the cooked eggs at room temperature for long and refrigerate them within 2 hours of cooking.
It’s also best to store them in a carton or an air-tight container. Keep them on an inside shelf rather than in the door, as frequent opening and closing of the fridge may cause the temperatures in this spot to fluctuate.
Initially, you may notice a gassy odor in your refrigerator when storing hard-boiled eggs. This is caused by hydrogen sulfide that forms when eggs are boiled.
However, this is normal and harmless; the smell usually dissolves within a few hours.
Lastly, it’s not recommended to freeze hard-boiled eggs, as both the egg white and yolk become tough and watery, making them less enjoyable to eat.
Peeled hard-boiled eggs
For the best quality, it’s best to wait to peel hard-boiled eggs until you’re ready to eat them or use them in a recipe.
If the eggs have already been peeled, it’s recommended to keep them in an air-tight container along with a damp paper towel to prevent them from drying out.
Just like unpeeled hard-boiled eggs, peeled ones should not be left at room temperature and should be refrigerated as quickly as possible.
Summary: Refrigeration is key to keeping your hard-boiled eggs safe and fresh. Hard-boiled eggs should be stored in the fridge within two hours of boiling and kept on an inside shelf instead of in the door. Avoid peeling hard-boiled eggs until you are ready to eat or cook with them.
How long can hard-boiled eggs last before spoiling?
When stored properly, hard-boiled eggs — peeled or unpeeled — can safely be kept in the refrigerator for approximately 1 week, according to the United States Department of Agriculture (USDA).
If you’re unsure how long your hard-boiled eggs have been stored, check the shell for a slimy or chalky appearance. If present, throw out the egg to be safe.
It’s important not to eat eggs past their prime, as this can put you at risk of foodborne illness with symptoms like diarrhea, nausea, and vomiting.
A spoiled hard-boiled egg may have a distinctive, unpleasant odor. If the egg still has the shell on, you may need to crack it to assess the smell.
Many people become alarmed if the yolk of a hard-boiled egg is greenish-gray in color. However, this doesn’t necessarily mean that your egg has gone bad.
The color of the yolk varies depending on cooking time and cooking temperature. When eggs are boiled for long, the yolk becomes paler and eventually turns greenish-gray.
This color occurs when you overcook the egg, making the iron from the yolk react with the hydrogen sulfide from the white.
While this might affect the texture and mouthfeel, it’s safe to eat.
Summary: Hard-boiled eggs can be kept for 1 week in your refrigerator. If the egg develops an unmistakable odor or slimy or chalky texture, discard it, as eating spoiled eggs can make you sick.
Summary
When handled and stored correctly, hard-boiled eggs stay fresh for about 1 week.
Hard-boiled eggs should be stored on an inside shelf of your fridge and cooled within 2 hours of cooking. For the best quality, store them unpeeled and inside an egg carton or air-tight container.
This way, you can reap the many benefits of this nutritious food.
