Making hard cooked eggs in the pressure cooker (Instant Pot or Crockpot Express) is a great "no fail" kind of recipe for beginners!
I saw this idea in a Facebook group for Crockpot Express Users:
To cook up to 24 eggs in one batch, use cardboard (cardboard ONLY) egg cartons stacked on each other. It will get wet, but won't disintegrate, and you can dry it out and use it again! It keeps the eggs from cracking during cooking and is great when cooking for a party! Deviled eggs, anyone? :)
