Hard-boiled eggs are a fantastic and healthy snack, a great addition to salads, and essential for deviled eggs. Making them is straightforward, but knowing how to store them properly and for how long is key to food safety and enjoyment. You might be wondering, how long do boiled eggs last in the fridge? Let’s dive into the details.
According to food safety experts, including the American Egg Board, hard-boiled eggs in their shell can be safely stored in the refrigerator for up to one week. This applies to eggs that are properly cooked and handled. However, if you’ve peeled your hard-boiled eggs, the recommendation changes. Peeled hard-boiled eggs should be consumed on the same day they are peeled for optimal safety and quality.
It might seem surprising that cooked eggs don’t have a longer shelf life than fresh, uncooked eggs, which can last for three to five weeks in the refrigerator. There’s a scientifically sound reason for this difference in longevity.
The United States Department of Agriculture (USDA) explains that the process of hard-boiling eggs removes the egg’s natural protective outer coating. This coating, also known as the bloom or cuticle, is crucial for preventing bacteria from penetrating the porous eggshell. Once this protective layer is gone, the pores of the shell are exposed, making it easier for bacteria to enter and potentially contaminate the cooked egg. This is why hard-boiled eggs don’t last as long as their raw counterparts.

To ensure your stored hard-boiled eggs are safe and delicious, follow these best practices:
- Cool them quickly: As soon as your hard-boiled eggs are cooked, transfer them to an ice bath to rapidly cool them down. This helps to stop the cooking process and prevents the gray-green ring from forming around the yolk.
- Refrigerate promptly: The USDA advises refrigerating cooked eggs within two hours of cooking. This two-hour window is crucial for preventing bacterial growth at room temperature.
- Proper storage container: Store your hard-boiled eggs in a lidded container in the refrigerator. This not only helps to keep them fresh but also prevents them from absorbing odors from other foods in your fridge.
“Never leave cooked eggs or egg dishes out of the refrigerator for more than two hours,” warns the Food and Drug Administration (FDA), “or for more than one hour when temperatures are above 90°F.” High temperatures accelerate bacterial growth, making it essential to refrigerate promptly, especially during warmer months. If you are taking a hard-boiled egg for lunch, make sure to refrigerate it as soon as possible once you reach your destination.
It’s a good idea to store hard-boiled eggs separately from raw eggs to avoid confusion. But if they do get mixed up, there’s a simple trick to tell them apart: the spin test!
Former Los Angeles Times test kitchen director Noelle Carter explained, “A hard-boiled egg will spin smoothly; a raw egg won’t.” This is because the contents of a hard-boiled egg are solid, allowing it to spin easily. A raw egg, with its liquid yolk and white, will wobble due to the shifting center of gravity.

You might notice a sulfurous smell coming from your hard-boiled eggs, even when stored correctly. The Egg Farmers of Canada assure us that this smell is normal and harmless. “The odor is caused by hydrogen sulfide, which forms when eggs are cooked. It’s harmless and usually dissipates in a few hours.”
However, there are signs that indicate a hard-boiled egg has gone bad. If the egg is slimy, has a chalky appearance, or emits a distinct, unpleasant rotten egg smell, it’s no longer safe to eat and should be discarded. When in doubt, it’s always best to err on the side of caution and throw it out.
While you might consider freezing hard-boiled eggs for longer storage, it’s generally not recommended. The American Egg Board, Egg Farmers of Canada, and the USDA all advise against freezing hard-boiled eggs. Freezing can negatively impact the texture, making the egg whites tough and watery when thawed. Instead of dealing with rubbery egg whites, it’s usually easier and more satisfying to simply cook a fresh batch of hard-boiled eggs when you need them.
In summary, hard-boiled eggs are a convenient and nutritious food to have on hand. Remember that unpeeled hard-boiled eggs last for about a week in the fridge when stored properly. Always prioritize food safety by cooling and refrigerating them promptly and being aware of the signs of spoilage. Enjoy your hard-boiled eggs knowing you’re storing and consuming them safely!
