How long will hard boiled eggs keep fresh and safe to eat as long as they are refrigerated?
Hard-cooked eggs should never be boiled – simmer them in water. If boiled or cooked too long, the protein toughens or becomes rubbery and a greenish or purplish ring forms around the yolk. Extremely fresh eggs are not recommended when making hard-boiled eggs. They are very difficult to peel. This is the best use for eggs nearing their expiration date. Refrigeration is necessary for hard boiled eggs if they eggs are not to be consumed within a few hours. Hard-cooked eggs in the shell can be refrigerated up to one week.
