When making a bunch of hard boiled eggs for meal prep or to use at a later date, I recommend keeping them in the shell. This will keep the eggs fresh the longest, and properly stored hard boiled eggs in the shell will last 7 days. Peeled hard boiled eggs kept in the fridge won't last as long and they will begin to dry up in a few days. If you want to peel and store them, make sure to wrap them in cling wrap to protect them from exposure to air. Properly stored peeled hard boiled eggs should last at least 5 days in the refrigerator.
