Quiche is a versatile dish that can be served at any time of day. This concoction of eggs, milk, cheese and any number of assorted meats and veggies baked into a pie crust can be tailored for breakfast, lunch or dinner, and can even be served as an hors d'oeuvre. Quiche is a relatively simple dish to make, and you can easily make it ahead of time if you're looking to free up time for other chores on the day you intend to serve it. All you would have to do is unwrap it and heat it up in the oven.
If you plan on serving your quiche sooner rather than later, refrigerate it after baking. Let the quiche cool down to room temperature before putting it in the fridge, but don't let it sit out for more than two hours. Letting it cool down keeps condensation from building up after you wrap it, which could make the dish soggy as it sits in storage. Wrap the quiche in plastic cling wrap or aluminum foil before putting it in the fridge.
Freezing Before Baking
You can also store quiche in the freezer, either before baking or after baking. To freeze before baking, mix all the ingredients together, pour them in a pie dish, place the dish on a tray and put the tray in the freezer. After a couple of hours, when the mixture is frozen solid, wrap the quiche in plastic wrap or aluminum foil, then place it in a large zip-top freezer bag for storage until the day you intend to bake and serve it. There's no need to thaw the quiche before baking. Place it frozen in a preheated oven and bake as usual, allowing between 10 to 20 minutes additional baking time.
Freezing After Baking
A less complicated way to store quiche in the freezer is to freeze it after baking. Make sure you let the quiche cool down to room temperature before wrapping and storing it. Tightly wrap the quiche in plastic wrap or aluminum foil and slide it into a zipper lock freezer storage bag before placing it in the freezer. On the day you plan on serving your quiche, you only have to warm it up in the oven rather than fully baking it again. Check that the dish is fully heated all the way through to a temperature of at least 160 degrees Fahrenheit before serving.
You can store a properly wrapped baked quiche for up to three days in the refrigerator. If you're storing it in the freezer, one to two months is the recomended storage time for a prebaked quiche, but you could go as long as three months. For a quiche that hasn't been baked beforehand, you can keep it in the freezer for up to a month. Make sure your freezer thermometer reads at least 0 degrees Fahrenheit before storing your quiche.
