Hard-boiled eggs should not be left out for more than 2 hours at room temperature. If it’s 90°F or hotter, the safe limit drops to 1 hour.

Quick Scoop

  • 2 hours max on the counter is the usual food-safety rule.
  • 1 hour max if the room or outdoor temperature is above 90°F.
  • After that, it’s safest to throw them out rather than risk foodborne illness.

If They’re Still Good

If you’re keeping them, refrigerate hard-boiled eggs within 2 hours of cooking, and store them in the fridge at 40°F or below. Properly refrigerated hard-boiled eggs are generally good for up to 1 week.

Practical Rule

  • At a picnic or buffet: keep them cold in a cooler.
  • For Easter eggs: if they’ve been out too long, don’t eat them.
  • When in doubt: toss them.

Bottom Line

If hard-boiled eggs have been sitting out overnight , they should be discarded.
