I’ve only recently started using my Instant Pot to boil eggs. I thought stovetop was less hassle until I discovered that every egg I made in the IP peels perfectly. That is pure gold.
Before reading any further, this only works with the Duo IPs as the Lux models only have a high pressure setting. One reason to get the Duo!
Here is my unscientific experiment. The pros, Amy+Jacky have rigorously tested their method here. Their definition of a medium boiled egg is 9 minutes on low pressure. Mine is 4 minutes on low. Perhaps that is the difference being at altitude makes? I live at about 3,500 ft above sea level.
Hard boiled eggs
Pour one cup of water into the pot. Place eggs on rack that came with the pot, or use a steamer basket. 5 minutes on high then vent. Rinse with cold water so I could handle them and voila! Perfect eggs.
Medium boiled eggs
Pour one cup of water into the pot. Place eggs on rack that came with the pot, or use a steamer basket. 4 minutes on low then vent. Dump into a bowl filled with cold water and wait about a minute. Dump the water and cover with cold water for about 5 minutes. Do a third cycle if the water is still warm.
Tried 1 minute on low. White done but yolk is very runny.
Tried 2 minutes on low. Edge of yolk is medium but middle is still very runny. (nice soft boiled egg)
Tried 3 minutes on low. Edge of yolk is medium but middle is a little runny.
Tried 4 minutes on low. Edge of yolk is medium and middle is just set. Perfect!
For fun, tried 8 minutes on low. Still hard boiled but on the softer side.
