Want to double a recipe for crustless quiche which for one recipe takes about 1 hr at 350 degrees in a 3 qtr pan. I want to cook two pans at the same
time so they will both be hot to serve at same time. Not sure how much longer it will take with double that amount. Recipe is mostly eggs and cheese mixture. Can you give me a good estimate of how much extra time to allow to cook two three qtr pans?
