You can cook a dozen eggs in a sheet pan, slice them up into patties, put them in breakfast sandwiches, and freeze them. One pan to wash, about an hour of prep, and that’s 12 breakfasts before you have to do it again.
I don’t even use a sheet pan, just right on the oven rack. I used to put a sheet pan on the rack below the eggs (i usually just do 2 at a time) in case of a Humpty Dumpty incident, but that has never happened.
