How Do You Reheat a Frozen Quiche?
To reheat a whole frozen quiche, preheat the oven to between 350 and 375 degrees Fahrenheit, and place the frozen quiche in the oven for about 25 to 30 minutes, or until it is heated through. The time it takes to reheat varies depending on the size of the quiche. You do not need to thaw the quiche before placing it in the oven.

Preheat the oven
Turn on the oven to a temperature between 350 to 375 degrees Fahrenheit. If you are using a prepackaged frozen quiche or have a specific recipe with reheating instructions, follow those directions regarding the oven temperature.
-
Wrap the quiche in foil
Wrap the quiche entirely in aluminum foil. 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 oven
Place the foil-covered frozen quiche on an oven rack positioned in the center of the preheated oven. Close the oven door, and let the quiche reheat until fully cooked through. 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.
