How to Tell if Hard-Boiled Eggs Have Gone Bad
Start with a sniff test. If an egg smells off or sulfurous, it’s best to toss it.
Next, check the appearance and texture. Spoiled hard-boiled eggs may develop a slimy or sticky exterior and can take on a slightly grayish color. If you notice any of these signs, discard the eggs.
How to Store Hard-Boiled Eggs
Just like raw eggs, hard-boiled eggs should always be refrigerated. After cooking, allow them to cool completely. Store unpeeled eggs in their shells in a covered container in the refrigerator.
If you’ve already peeled them, place the eggs in a container with a tight-fitting lid. You can add a damp paper towel to the container to help prevent them from drying out.
