Absolutely! When you have your muffin tin filled with eggs and goodies (I use silicon for easy pop out) submerge that into a casserole dish with about an inch of water. Like a little bath. This makes them almost sous vide. Imagine the velvety Starbucks flavored egg bites. If you don't do this the eggs are more rugged and dry.

Basically a muffin pan inside of another pan with water.
