Grease silicone egg bite container(s) with non-stick spray. Add water to the bottom of the Instant Pot. Set aside.
To a 4 cup pourable container or bowl, add eggs, milk, salt, and pepper and whisk together.
Pour egg mixture into molds dividing evenly*. Divide ham, cheese, and chives evenly and add to each egg bite cup.
If desired, wrap mold tightly in tinfoil**. Place filled egg bite mold on Instant Pot trivet and carefully lower trivet with the mold into the bottom of the Instant Pot.
Secure lid on Instant Pot and set vent to seal. Select the Steam button and set for 10 minutes. It takes about 5-10 minutes to come to full pressure, then cook time will countdown.
Once cook time is complete, allow pressure to release naturally for 10 minutes and then release remaining pressure manually.
Using oven mitts, remove trivet and mold from Instant Pot, unwrap tinfoil if using, and carefully remove the egg bites from the molds.
Serve immediately or cool, place in a container, and refrigerate for later.
Notes
*The cups should be almost to the top with a little space.
The Instant Pot brand silicone cup has 70ml per silicone cup (6 eggs will produce 7 egg bites)
Smaller egg bite silicone cups, such as GOKCEN’s (OGGO) brand, have 35 ml per cup. 6 eggs will produces 14 egg bites in 2 containers, cooking both at the same time.
**Wrapping silicone mold is not necessary, but will produce more uniform egg bites.
Wrapped egg bites will not rise as much and will produce a flatter top.
Unwrapped egg bites will rise slightly, but will deflate after a couple of minutes.
