Add 1-16 eggs in a single layer and not touching the walls (to avoid cracking). Close the lid, set valve to Sealing and press Pressure Cook on High or Manual button and adjust time to 5 minutes.
Let pressure come down on its own for 5 minutes, then turn valve to Venting to release remaining steam. When pressure pin drops, open the lid and remove cooked eggs into an ice bath. Let eggs cool off for 5 minutes.
Refrigerate peeled eggs in a container with a lid for up to 3 days. Unpeeled eggs can be refrigerated uncovered for up to 7 days. Unpeeled eggs last longer. Freshly cooked eggs last up to 2 hours at room temperature.
