To reheat a frozen, pre-cooked, quiche:Pre-heat the oven to 350°F. Wrap the quiche in foil to prevent further browning. If the frozen quiche is already in a metal or foil pie pan, you only need to cover the top with aluminum foil. If you are reheating individual slices, wrap each one individually in foil, and place the slices on a baking sheet.Place the quiche in the ovenPlace the foil-covered frozen quiche on an oven rack positioned in the center of the preheated oven. A whole quiche takes 25 to 30 minutes to fully reheat. Individual pieces of frozen quiche reheat much faster, however, in about 10 to 15 minutes.
