Depending on how you like your eggs will dictate the cook time.
I like the yolk moist and not solid, 6-7 minutes should do it. I remove my egg from oven and cover with lid. Grill-Man likes his eggs cooked all the way through and then some. At the 7 minute point, I add a lid to his egg to steam for 2 minutes without turning to a crisp. Set timer.
