We love quiche — perfect for weekday leftovers or Christmas morn. But a soggy crust? Sad disaster. Reheat it right with this oven trick—crisp, tasty, done!

Can Quiche Sit Out Overnight?
No, quiche should not set out overnight.
Quiche shouldn’t be kept at room temperature for more than 2 hours.
Even if you are in a hurry we recommend that you cover the quiche will aluminum foil and place it in the fridge for quick storage.
How Long Will Quiche Last in the Refrigerator?
Cooked quiche will last 3-4 days in the refrigerator.
You can extend the life of leftover quiche by freezing what remains but only if it has been in the fridge for less than 4 days.
Can You Make Quiche Ahead of Time and Reheat It?
Yes, you can make quiche ahead of time and reheat it.
You can fully bake it, then allow it to cool and store it in the refrigerator.
You can also fully bake it, allow it to cool and then freeze it.
You can also put together a quiche in advance and bake it when you are ready to serve it.
In this instance, you would store it in the fridge until you are ready to cook it.
Uncooked quiche should not be kept in the fridge for more than 24 hours before baking it.

Helpful Tips on Reheating Quiche
- Allowing the quiche to come to room temperature prior to reheating it will help with keeping the texture of the crust and ingredients close to the original desired texture.
- If reheating quiche in the microwave cut it into small pieces prior to reheating it. This will allow you to reheat it quicker which will help keep the crust from getting too soggy.
- If reheating the quiche in the microwave be sure to use a microwave-safe dish. This is important and easy to forget.
- Allow the quiche to set for a couple of minutes prior to serving it.
- Be sure the oven is at 350 degrees prior to putting the quiche in the oven. If you allow the oven to heat up with the quiche in it, the crust may turn out soggy.

How to Reheat a Quiche in the Oven
A quiche is cooked in the oven and reheating it in the oven is by far the best option to retain that crispy crust and the texture that we all love.
- Set your quiche out and allow it to come to room temperature.
- Preheat your oven to 350 degree.
- Place your quiche on a baking sheet and cover it with aluminum foil.
- Bake the quiche in the oven for about 15-25 minutes or until it is heated all the way through. (Most often 15 minutes does the trick but check the internal temperature to be certain.)

How to Reheat Quiche in the Microwave
While we believe that reheating quiche in the oven is the optimal choice for the tastiest quiche sometimes we just don’t have the time for that.
That is when we wind up heating our quiche in the microwave.
Do note that when reheating quiche in the microwave you will want to do it one slice at a time.
Be careful not to overcook the quiche because it will become soggy if overheated.
- Set your quiche out and allow it to come to room temperature.
- Place a slice of quiche on a microwave-safe plate.
- Microwave the quiche on medium-high for 30 seconds.
- Check the quiches’ internal temperature. The internal temperature should be 165 degrees.

How to Freeze a Quiche
You can freeze a quiche. If the quiche is already cooked you can freeze it for up to two months.
If the quiche has not been cooked you can freeze it for up to one month.
Baking a quiche prior to freezing it makes it a bit easier to handle.
Make sure that your quiche has cooled to room temperature before placing it in the freezer.
(Do note that you shouldn’t leave a quiche out at room temperature for more than 2 hours.)
- Cover the quiche with plastic wrap.
- Cover the top of the quiche with aluminum foil.
- Place it on a level spot on the freezer. Don’t put anything on top of it.

Conclusion
Reheating quiche may seem like a complicated process but just remember that your means of reheating depends on your particular need.
Use oven if you want a perfectly reheated quiche, and use a microwave, if you’re in a rush.
